Title: COMPUTED TOMOGRAPHY METHOD AND APPARATUS FOR CARRYING OUT SAID METHOD
Abstract:
The invention substantially relates to a computed tomography method, in which the operator initially sets an expected approximate scanning area, in which a first sample scanning line is a scanned in a mid-scanning row of the expected scanning area and the tissue texture captured by this sample scanning line is analysed in respect of whether the desired region to be examined is captured by the scanning line, in which the first organ boundary is then searched for with the aid of further sample scanning lines in accordance with a binary search, proceeding from the mid-scanning row of the expected scanning area up to a first limit of the expected scanning area, in which, in a corresponding manner, a further organ boundary is ascertained between the mid-scanning row and a second limit of the expected scanning area and in which, then, scanning lines for the actual examination are substantially only captured between the two ascertained organ boundaries. The advantage of the invention consists of there no longer being any need for a preliminary scan and for human intervention when adjusting the scanning area and, at the same time, of a more accurate scan being produced. This avoids errors, reduces the radiation to a minimum and simultaneously dramatically reduces the cycle time per scan.
