Dynamic, incremental computed tomography using a high heat capacity tube, solid-state detector, and automated injector. Potential in body imaging.
Using a new graphite tube, a prototype solid scintillating detector, and an automated injector, improvements were made in body computed tomography image quality. First, more scans with shorter interscan delay could be obtained with the improved tube. Second, liver image quality was improved with the use of higher techniques and a more consistent contrast bolus delivery with a mechanical injector. Last, body surveys were improved because the higher heat capacity tube provided the ability to rapidly scan and examine an entire region during the injection of contrast.
