Figure 2: (a) A reconstructed transaxial slice and count profile of a Jaszczak phantom acquired for 360° arc with 180° detector configuration after attenuation correction based on Chang's technique as available in Siemens workstation. The acquisition was done on a Siemens e.cam^TM camera capable of acquisition in both 360° and 180° arcs. (b) A reconstructed transaxial slice and count profile of a Jaszczak phantom acquired in heart mode (180° tomographic arc with 90° detector configuration) acquired on the same camera after attenuation correction based on Chang's technique as available in Siemens workstation. Angular variation of counts demonstrated for the 180° arc
