A gamma ray detector is disclosed.

The gamma rays are detected in a gamma ray detector (20).

The detector may be, for example, a solar wind particle detector, an alpha ray detector, a gamma ray detector, or the like.

The gamma ray detector comprises a gamma ray detector for converting a gamma ray photon into an analog pulse, and a single channel analyzer or the analog signal measurement system.

A second gantry (14) comprises a gamma-ray detector that detects gamma-rays emitted from the subject.

A gamma ray detector for determining the position of gamma ray interactions has at least one module (1).

Still further, the present invention relates to a gamma ray detector (3, 51) as well as to a medical imaging device (49) comprising this gamma ray detector (3, 51).

Gauge (10) also includes a gamma-ray detector which produces signals as a response to the detected gamma-rays.

The gamma ray detection window of the gamma ray detector is adjusted in compliance with the characteristics of the organic scintillator.

A portable gamma-ray detector for indicating the intensity of a source of gamma-rays, the nature of the source, and the direction to the source relative to an axis of the detector.

The gamma ray detector can be a proportional gas counter, a scintillation based detector, or a semiconductor detector.
