Tomographical acquisition method with two detectors and with sighting centre distinct from rotation centre. |
摘要 |
<p>In order to acquire measurement data during a nuclear medicine experiment of the tomographic type, with a gamma camera having two detector heads (8a, 9c), each of these heads is directed on a siting centre (28) while the assembly constituted by these two heads rotates around a centre of rotation (2) of the apparatus, the centre of rotation being separated from the siting centre. It is shown that this procedure makes it possible to go faster (34) on the one hand for the acquisition and furthermore to contribute to work involving tomography images which are more exact and more easily calculated. <IMAGE></p> |
