Method for determining generation position of radiation signal in measurement region, and measurement apparatus for simultaneously detecting radiation events of decaying radionuclides in measurement region

摘要

The present invention relates to a method for determining a generation position 9 of a radiation signal 10 in a measurement region 7. The radiation signal 10 is detected from the measurement region 7 by a number of radiation detectors 2 at a certain measurement time. A measurement value associated with the measurement time is provided, and the determination of the origination position 9 is performed by measuring all radiation detector 2 measurements and a known positional relationship measurement of each other radiation detector 2 using a reference data set. And executed in consideration of The invention also relates to a measuring device 1 for simultaneously detecting radiation events of decaying radionuclides 8 in the measurement region 7. A number of radiation detectors 2 are provided in the measuring head 1.1. In an advantageous embodiment of the method and measuring device 1 according to the invention, an ultrasonic probe 16 is additionally arranged on the measuring head 1.1. Detection, determination and imaging of the two-dimensional intensity distribution of the radiation signal 10 of the radionuclide 8 is possible in the entire measurement region 7.
