Discrete tomography (DT) is a set of tools for reconstructing the inner structure of objects consisting of only few different homogeneous materials. We propose a new method for multivalued DT, which performs the reconstruction as an energy minimisation task. For this algorithm, we define an energy function that can mathematically formulate the reconstruction task, and design a novel optimisation process for approximating the minima of this energy function. We validate the algorithm by comparing its performance with other cutting-edge reconstruction algorithms from the literature. We show that our method can compete with the currently used reconstruction techniques and under certain circumstances (e.g. with a low number of projections, or when the projection data are affected by random noise) it can even outperform them.

In binary tomography the goal is to reconstruct the innerstructure of homogeneous objects from their projections. This is usually required from a low number of projections, which are also likely to be affected by noise and measurement errors. In general, the distorted and incomplete projection data holds insufficient information for the correct reconstruction of the original object. In this paper, we describe two methods for approximating the local uncertainty of the reconstructions, i.e., identifying how the information stored in the projections determine each part of the reconstructed image. These methods can measure the uncertainty of the reconstruction without any knowledge from the original object itself. Moreover, we provide a global uncertainty measure that can assess the information content of a projection set and predict the error to be expected in the reconstruction of a homogeneous object. We also give an experimental evaluation of our proposed methods, mention some of their possible applications, and describe how the uncertainty measure can be used to improve the performance of the DART reconstruction algorithm.

We describe a new approach for the uncertainty problem arisingin the field of discrete tomography, when the low number of projections does not hold enough information for an accurate, and reliable reconstruction. In this case the lack of information results in uncertain parts on the reconstructed image which are not determined by the projections and cannot be reliably reconstructed without additional information. We provide a method that can approximate this local uncertainty of reconstructions, and show how each pixel of the reconstructed image is determined by a set of given projections. We also give experimental results for validating our approach.

In this work we study the relation between the quality of a binary tomographic reconstruction and the choice of angles of the projections. We conduct experiments on a set of software phantoms by reconstructing them from different projection sets using three different discrete tomography reconstruction algorithms, and compare the accuracy of the corresponding reconstructions with suitable approaches. To validate our results for possible real-world applications, we conduct the experiments by adding random noise of different characteristics to the simulated projection data, and by applying small topological changes on the phantom images as well. In addition, we also discuss some consequences of the angle-selection dependency and possible practical applications arising from the field of non-destructive testing, too.

It has already been shown that the choice of projection angles can significantly influence the quality of reconstructions in discrete tomography. In this contribution we summarize and extend the previous results by explaining and demonstrating tile effects of projection selection dependency, in a set of experimental software tests. We perform reconstructions of software phantoms, by using different binary tomography reconstruction algorithms, from different equiangular and non-equiangular projections sets, under various conditions (i.e., when the objects to be reconstructed undergo slight topological changes, or the projection data is affected by noise) and compare the results with suitable approaches. Based on our observations, we reveal regularities in the resulting data and discuss possible consequences of such projection selection dependency in binary tomography.

We study how the quality of an image reconstructed by a binary tomographic algorithm depends on the direction of the observed object in the scanner, if only a few projections are available. To do so we conduct experiments on a set of software phantoms by reconstructing them form different projection sets using an algorithm based on D.C. programming (a method for minimizing the difference of convex functions), and compare the accuracy of the corresponding reconstructions by two suitable approaches. Based on the experiments, we discuss consequences on applications arising from the field of non-destructive testing, as well.

We propose a novel Markovian segmentation model which takes into account edge information. By construction, the model uses only pairwise interactions and its energy is submodular. Thus the exact energy minima is obtained via a max-flow/min-cut algorithm. The method has been quantitatively evaluated on synthetic images as well as on fluorescence microscopic images of live cells. {\textcopyright} 2010 IEEE.

The industrial nondestructive testing (NDT) of objects seems to be an ideal application of discrete tomography. In many cases, the objects consist of known materials, and a lot of a priori information is available (e.g., the description of an ideal object, which is similar to the actual one under investigation). One of the frequently used methods in NDT is to take projection images of the objects by some transmitting ray (e.g., X- or neutron-ray) and reconstruct the cross sections. But it can happen that only a few number of projections can be collected, because of long and/or expensive data acquisition, or the projections can be collected only from a limited range of directions. The chapter describes two DT reconstruction methods used in NDT experiments, shows the results of a DT procedure applied in the reconstruction of oblong objects having projections only from a limited range of angles, and, finally, suggests a few further possible NDT applications of DT.

Three problems of emission discrete tomography (EDT) are presented. The first problem is the reconstruction of measurable plane sets from two absorbed projections. It is shown that Lorentz theorems can be generalized to this case. The second is the reconstruction of binary matrices from their absorbed row and columns sums if the absorption coefficient is μ0 = log((1+v/5)/2). It is proved that the reconstruction in this case can be done in polynomial time. Finally, a possible application of EDT in single photon emission computed tomography (SPECT) is presented: Dynamic structures are reconstructed after factor analysis.

Introduction: During the last four years a Picture Archiving andCommunication System (PACS) has been developed in the University mainly for educational purposes. The original intention was to use the system as a non-stop routine PACS, so the images of the modalities of the system should be available to the workstations connected to the University network at the different clinics. Material and method: Two CTs, one MR, one ultrasound, three fluoroscopy devices, two SPECTs, two gamma cameras and one X-ray film scanner have been connected to the computer network at SZOTE. One Silicon Graphics Challenge DM central image server collects the images and related data. The picture archiving and communication is DICOM conform. An ORACLE data management system facilitates the data retrieval. Step by step testing of the operation of the system began with the transport, conversion and archiving of images of two CTs, one MR and one SPECT: Results: The daily archiving of about 5000 images on 80-100 patients gradually demonstrated the slight incompatibility of DICOM or Interfile of the image modalities or converter stations and the minor shortcomings of the software. Three educational cabinets have been installed, in which the practical teaching of radiology has been performed since 1996. Discussion/conclusion: Full automatization is necessary for handling such huge amount of images. For this the PACS and RIS/HIS connection was needed which was successed as well.

The SZOTE Picture Archiving and Communication System (SZOTEPACS) is used for: - teaching graduate and postgraduate students - picture archiving for scientific purposes - archiving and consulting data from radiological and nuclear medicine examinations In order to implement these tasks, archiving is not enough; it is also necessary to display images in various clinics and departments. On the basis of the cost/benefit principle, after an appropriate selection, Silicon Graphics workstations (Indy Modeler R5000PC microprocessor, 32 MB RM, 1 GB disc, 17{\textquotedblright}/8 bit color monitor) and Albacom Activa Standard computers (Intel Pentium 200 Mhz CPU, 32 MB EDO RAM, 2.1 GB disc, 17{\textquotedblright} GoldStar 78i color monitor) were implemented into the system. The problem of a relatively easy and fast search in the PACS image database is solved, if access is granted. The images are transferred to the workstations (viewing stations) in DICOM 3.0 format. The images processing program OSIRIS is suitable for the processing of images in DICOM format. The resolution of the viewing station display is: Silicon Graphics 1280 x 1024 x 8 bit; Albacom 1600 x 1200 x 8 bit. For the matrix specified above, the 256 grey scale is suitable for display of the chosen images in good quality, consultation with clinicians, and the comparison of control examinations with previous ones.

SZOTE-PACS has been developed since 1995. The aim was to collectdigital images produced by existing and new medical imaging modalities which are placed in different buildings. After collection the images are transmitted and built in to a central database. From the images database the PACS users are able to query study data and images easily. The software system consists of three main type of clients: the admitting, the server and the viewing subsystems taking into account the local circumstances. The images produced by the modalities go to the admitting stations. The studies that are not in DICOM format (Interfile, ACR-NEMA 2.0) are converted to DICOM. All studies are sent to the PACSW server in DICOM format. The images are managed by an Oracle Database Se3rver on the PACWS server. The end users are able to query the data by SQL at the viewing stations. The SZOTE-PACS system provides an efficient PACS for physicians, medical doctors and students. It can be used for making educational material, scientific work and diagnosis as well. The completed parts, the process of the working and the plan of the future development of this software system will be presented.

Introduction: The progress in computer techniques has resultedin the digital archivation and transport of images of radiology and nuclear medicine without loss of information. The images and image series produced by various image modalities are converted to a uniform image format, which provides their interconnectivity and interoperability. The image transport is very important at hospitals comprising pavilion systems. Material and method: Through the computer network of the SZOTE Picture Archiving and Communication System (SZOTE PACS) serves the radiology education with the aid of computer displays. Result: ATM network devices allow the fast transfer of images. Silicon Graphics and PC viewing stations provide fast image processing and presentation. Use of the DICOM standards in SZOTE PACS permits the development of teleradiology services. Discussion: The hardware structure and the parameters of the system will be presented in detail. The PACS is connected to the Radiology Information System of the Department of Radiology and the Department of Nuclear Medicine. Conclusion: This makes automatic image archiving possible. The system is user-friendly: it can be handled with minimum computer knowledge. A group has been established at the University to perform the PACS management.

In 1995 when the development of the SZOTE-PACS (PACS of theAlbert Szent-Gy{\"o}rgyi Medical University) begun, we chose DICOM as the common file format and a possible file transfer protocol for our PACS. Now, we present the problems and our solutions connected with the application of the DICOM standard. According to our experiences the problems can be explained as the misinterpretation of the complex, complicated and extensive standard. After some minor adjustments the exchange of study data between different systems, vendors, and even modalities was generally successful. Diagnostic tools for testing DICOM files coming from different modalities are a help to the adjustments. In the second part we present the automatic procedures built into SZOTE-PACS: automatic data-conversion, -edition (including existing RIS data and predefined study parameters), lossless image data compression, checking and transmission to the Archive.

The main aims of the development were to provide a tool to collect studies from different format and to use the archived information in the education and in the clinical routine. The system is able to collect studies from CT, MR, NM, US, SPECT modalities, from X-film scanners and from any station communicating according to DICOM storage- query/retrieve service class. The data are automatically converted from Interfile 3.3, ACR-NEMA 2.0 or TIFF formats into DICOM 3.0 format and stored in the data-server of the system. The study headers can be edited by graphic editor programs. The PACS can collect information also from the Radiology Information System (RIS) of the Department. In order to have an effective database management the users may use Oracle to retrieve, present or modify data. The Oracle system stores the whole header information but does not contain the image data itself. The clients can reach the database using capabilities and it can be used to avoid unauthorized connections. Our DICOM server gives the studies to the processing stations (PC-s, UNIX workstations or X- terminals). Here the user can retrieve, process and present studies, furthermore, as a special aim, they can edit text and images into HTML format to create graduate and post-graduate educational material. Then this educational material can be stored also in the system/CD-ROMs and can be used in the training of medical students. Our PACS system is modular, flexible and based on a 4th generation functional programming language Tcl/Tk. This language has Oracle connection and graphical interfaces. In this way the same source code can be used by each client. } } @inbook {1325, title = {K{\'e}p-archiv{\'a}l{\'o} {\'e}s tov{\'a}bb{\'\i}t{\'o} rendszer szoftver{\'e}nek fejleszt{\'e}se (SZOTE-PACS)}, booktitle = {Informatika a fels{\H o}oktat{\'a}sban {\textquoteright}96 {\'e}s Networkshop {\textquoteright}96}, year = {1996}, month = {1996}, pages = {1186 - 1192}, publisher = {Debreceni Egyetem}, organization = {Debreceni Egyetem}, address = {Debrecen}, abstract = {The Picture Archiving and Communication System developed for theMedical University of Szeged (called SZOTE-PACS) is described.

The problem of presentation of 3D SPECT (Single-Photon EmissionComputed Tomography) images are considered. Instead of the classical 2D image presentation methods (displaying the slices) the following methods are studied: presentation of sections with a 3D reference image, generation of 3D phase and amplitude images (for gated heart studies), surface rendering and volume rendering by 3DVIEWNIX (MIGP, Univ. Pennsylvania) software. The projections are collected by a single-head SPECT system. After preprocessing (centre-of-rotation, uniformity correction) and reconstruction of the transversal sections absorption- correction and special 3D processing can be done. There are clinical programs for the different kinds of studies (e.g. brain SPECT, heart SPECT). The processed section images are stored and converted into Interfile 3.3 format. The first two presentation methods are available on our SPECT system. In order to use the 3DVIEWNIX software the file of the reconstructed sections is converted into a generalized ACR-NEMA format and transferred into our university network. The 3DVIEWNIX system runs on UNIX machines. It is suitable to visualize, manipulate and analyse multidimensional image data like SPECT. The results of the surface and volume rendering of brain and heart studies are presented.
