Simulated emission computerized tomography of the left ventricle using rotating slant hole collimator and 2 camera positions


, : Simulated emission computerized tomography of the left ventricle using rotating slant hole collimator and 2 camera positions. Journal of Nuclear Medicine 25(3): 343-351

Limited-angular-range tomography leads to an elongating distortion of the object in the direction of the z axis (perpendicular to the camera face). Two-view tomography appends to the usual data set another set of projections taken after the camera is rotated 90.degree. about an axis perpendicular to z. Two-view tomography was investigated using a rotating-slant-hole collimator, 12 projections per view and the SMART iterative algorithm. Computer simulations extended previous results to include noise and attenuation. Phantoms imaged were the Au-rings in air and a ventricle phenatom angled with respect to the z axis and placed in a water bath. Two-view results were generally superior compared to 1-view results, were subject to some artifact in imaging defects, but could detect defects by looking at the differences between 2 sets of images, and were fairly insensitive to ventricle angulation. Two-view tomography has promise for Tl-type imaging [in humans].

BACKGROUND. Multicentric breast carcinomas have a higher frequency of axillary lymph node metastasis than unifocal tumors of similar stage. It remains unclear whether this merely reflects larger tumor volumes or a different biologic behavior. The...
