Abstract
A CT scanner ( ) for obtaining a medical diagnostic image of a subject includes a stationary gantry ( ), and a rotating gantry ( ). The detected radiation is reconstructed and divided into sub-portions, which sub-portions are aligned by a registration processor ( ). The registered images are stored in a high resolution memory ( ) and a maximum artery enhancement value is calculated from the high resolution images. A resolution reducer ( ) reduces the resolution of the high resolution images. Time-density curves are found for the voxels of the images, which time-density curves are truncated to eliminate unwanted data, and analyzed to determine characteristic values. A perfusion calculator ( ) calculates perfusion by using the maximum artery enhancement value and the characteristic values. A diagnostician can view any one of a low resolution image, a high resolution image, and a perfusion image on a video monitor ( ).
