Iterative reconstruction of detector response of an Anger gamma camera

Convergence Study of an Iterative Joint Detector

The joint detection of all users in a multiple access communication system is known to greatly enhance the system performance. The optimal joint detector has a complexity which is exponential in the number of users and is, therefore, impractical. Suboptimal algorithms attempt to achieve near optimal performance with reduced computational complexity. The suboptimal joint detection literature dea...

Stenosis quantification in coronary CT angiography: impact of an integrated circuit detector with iterative reconstruction.

OBJECTIVES The objective of this study was to assess the value of an integrated circuit (IC) detector, potentially improving spatial resolution by means of reduced cross talk between detector channels, in coronary computed tomographic (CT) angiography regarding image quality and stenosis quantification compared with conventional detector technology. MATERIALS AND METHODS In the ex vivo part o...

Comparison of myocardial perfusion imaging between the new high-speed gamma camera and the standard anger camera.

BACKGROUND Cadmium-zinc-telluride (CZT) solid-state detectors have been recently introduced into the field of myocardial perfusion imaging. The aim of this study was to prospectively compare the diagnostic performance of the CZT high-speed gamma camera (Discovery NM 530c) with that of the standard 3-head gamma camera in the same group of patients. METHODS AND RESULTS The study group consisted...
