A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy. The applications of scintigraphy include early drug development and nuclear medical imaging to view and analyse images of the human body or the distribution of ...
Coded aperture mask for gamma camera (for SPECT) Coded apertures or coded-aperture masks are grids, gratings, or other patterns of materials opaque to various wavelengths of electromagnetic radiation. The wavelengths are usually high-energy radiation such as X-rays and gamma rays. A coded "shadow" is cast upon a plane by blocking radiation in a ...
The geometry of a pinhole camera. Note: the x 1 x 2 x 3 coordinate system in the figure is left-handed, that is the direction of the OZ axis is in reverse to the system the reader may be used to. The geometry related to the mapping of a pinhole camera is illustrated in the figure. The figure contains the following basic objects:
SPECT image (bone tracer) of a mouse MIP Collimator used to collimate gamma rays (red arrows) in a gamma camera. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1]

In 1957, he invented the scintillation camera, known also as the gamma camera or Anger camera. Anger also developed the well counter, widely used in laboratory tests to measure radioactivity in samples. Anger also developed a multi-plane tomographic radiation scanner using the Anger camera and a focussed radiation collimator. [1]
Later systems used a Sodium iodide (NaI) scintillator, as in a gamma camera. [7] The detector must be connected by mechanical or electronic means to an output system. This could be a simple light source over photographic film , dot matrix printer , oscilloscope or television screen .
Camera resectioning is the process of estimating the parameters of a pinhole camera model approximating the camera that produced a given photograph or video; it determines which incoming light ray is associated with each pixel on the resulting image. Basically, the process determines the pose of the pinhole camera.
