METHOD FOR DETERMINING THE POINTS OF ORIGIN OF RADIATION SIGNALS IN A MEASUREMENT ZONE, AND MEASURING APPARATUS FOR SIMULTANEOUSLY DETECTING RADIATION EVENTS OF DECAYING RADIONUCLIDES IN THE MEASUREMENT ZONE

摘要

A method for determining the locations of origin of radiation signals in a measurement zone in which radiation signals are detected from the measurement zone by means of a quantity of radiation detectors at a measurement time, and measurement values associated with the measurement time are provided. The determination of the locations of origin is carried out taking into account the measurement values of all of the radiation detectors and of the known positional relationships of the radiation detectors relative to one another using a reference dataset. The measuring device of the invention, for the simultaneous detection of radiation events of decaying radionuclides in the measurement zone has a quantity of radiation detectors provided in a measuring head. An ultrasound probe may be arranged in the measuring head. Detection, determination and imaging of a two-dimensional intensity distribution of radiation signals of a radionuclide is possible in the entire measurement zone.
