||Analysis of dermatological images for teledermatology and diagnostic applications|
We are researching and developing image processing algorithms for dermatological applications in diagnostic and decision making systems as well as for education. This includes the creation of a personalized surface model from a set of color and depth camera images, detection and classification of dermatological findings, such as psoriasis lesions and plaques, as well as longitudinal analysis of changes.
||Retina image analysis|
Methods for the automatic detection and evaluation of Glaucoma and other eye diseases from screening examinations.
||Elastic Registration of Multimodal Prostate Images|
A novel method for non-rigid registration of transrectal
ultrasound and magnetic resonance prostate images based on a non-linear
||Estimation of Linear Shape Deformations and its Medical Applications|
We consider the problem of planar shape registration on binary images. Our primary goal is to investigate novel methodologies which work without feature point extraction and established correspondences; avoid the solution of complex optimization problems; and provide an exact solution regardless of the strength of the distortion. The newly developed techniques are validated on medical images.
Computer aided surgical planning with semi-automatic segmentation, implant insertion and biomechanical analysis
A novel solution for reassembling a broken object from its parts without established correspondences, where each part is subject to a linear deformation.
||Assessment of tracheal stenoses, infra-renal aortic aneurysms, and colorectal polyps|
Skeletonization has been successfully applied in the following three medical applications:
assessment of laryngotracheal stenosis,
assessment of infrarenal aortic aneurysm, and
unravelling the colon.
||Quantitative analysis of tubular tree structures|
A method for computationally efficient skeletonization of three-dimensional tubular structures was proposeded.
It is specifically targeting skeletonization of vascular and airway tree structures in medical images but it is general and applicable to many other skeletonization tasks.
||Transforming CT studies of the pelvic region to a common reference frame|
Our automatic registration method was tailored to the needs of a model-based segmentation framework of the pelvic area in CT studies in collaboration with GE Medical Systems. Registration was used as a preprocesing task. The goal of it was the acceptable alignment of the pubic bone area (where the two organs of interest, the prostate and bladder are located) of studies from different patients.
SZOTE-PACS is the Picture Archiving and Communication System of Albert Szent-Gyorgyi Medical University. It is able to collect studies from CT, MR, SPECT, US and modalities and convert them into DICOM format.
||Organ segmentation from 3D CT images|
Study and development of image segmentation algorithms for different organs from CT images for radiotherapy planning purposes.
||Beam Hardening and Metallic Artifacts Correnction Techniques in Computerized Tomography Study|
A joint project is in process between the University of Szeged Image Processing Group and Department of Optics and Quantum Electronics and GE Medical Systems (GEMS) Budapest, to study the problems connected with CT image corrections.
||Robotically assisted, image guided planning and execution of percutaneous therapies|
We developed a unified framework for percutaneous therapies utilizing localization frames and implemented an application using CT imaging and a robot.
||MR intensity standardization and fuzzy segmentation of MR images|
We developed an image processing method for MRI intensity
We also introduced new, fast implementations of the fuzzy connectedness algorithm that allows segmentation at interactive speeds.
We developed a new segmentation "workshop" for brain MRI segmentation using standardized MR images and the fast fuzzy connectedness algorithms.
MicroSEGAMS is an AMIGA-based system to perform and evaluate isotope-diagnostic studies. It was created using the experiences with SUPER-SEGAMS.
Supplement to SEGAMS-80 with the creation and evaluation of SPECT studies. It became possible to create user programs for the system in FORTRAN.
The improvement of the SEGAMS system that made possible to automate the image acquisition and evaluation. The system could be generated in different languages as well.
SEGAMS: A tree-structured hierarchical data processing system.
The software system of a gamma camera connected to a minicomputer that can be used to acquire and evaluate the most common types of nuclear medicine studies used in clinical routine.
Detecting changes in images acquired by a scintigraph about the distribution of radioactive isotopes is a difficult task. Image processing attempts were made to improve the detection of changes.
