摘要

Data acquisition apparatus for computerized tomography by emission of gamma radiation and its operation. This invention describes the acquisition electronics of a gamma radiation emission tomography system, which encompasses two related nuclear medicine techniques: single photon emission tomography (spect) and positron emission tomography (pet), with a reduced number of gamma cameras and a minimum dead time, and that integrates all the processing electronics for the characterization of radiation and resolution of coincidences in a single electronic device. This invention simplifies the precise distribution of the clock to all elements of the system and reduces the problems arising from the temporal synchronization of all elements to a single time base. In addition, it achieves: a reduction of costs, in front of an analogical system; a reduction in the size and a simplification of the calibration process of the final equipment.
