Claims

[Scope of utility model registration request]

In a scintillation camera device that detects radiation from a subject and displays the position of the detected radiation on an oscilloscope via a position calculation circuit, addition circuit, and pulse height analyzer, horizontal synchronization creates a horizontally synchronized sawtooth wave synchronized with the detected radiation. circuit, a pulse stretcher that extends the pulse width of the adder output, and an unranked signal obtained through the pulse height analyzer, and a detected position signal (x , y-coordinate signal) and displays the detected radiation image in the same way as the oscilloscope.
At the same time, a storage type monitoring oscilloscope that displays the energy wave height distribution image obtained through the horizontal synchronization circuit and the pulse stretcher, the position calculation circuit output input to the storage type monitoring oscilloscope, and horizontal synchronization. A switch is provided for switching the output of the recirculator output and the output of the pulse stretcher, and for switching between the detected radiation image and the pulse height distribution image displayed on the storage type oscilloscope. A scintillation camera device having a wave height distribution display function, characterized in that the scintillation camera device is configured to display the wave height distribution and set a window after confirming the wave height distribution.
