Description

SUPER-SEGAMS is the improvement of SEGAMS-80. It is possible to create user programs for the system in FORTRAN.

During the rapid motion of the heart the central vascular system cannot be imaged directly due to the low signal-to-noise ratio. Using the ECG-gated acquisition technique each heart cycle can be divided into n intervals of the same length and then by summing images taken at the same phase of the heart cycle it is possible to produce images of a representative heart cycle. Images obtained by summing data from several hundreds of cycles have acceptable signal-to-noise ratio and with such images the pumping function of the heart can be well studied. SUPER-SEGAMS allows performing ECG-gated heart studies also, for which an ECG had to be fitted to the system.

SUPER-SEGAMS also includes the program system – as an experimental feature – that allows performing SPECT studies.
