A calibration rig for an imaging system comprising:
- a base;
- a holder extending from the base, the holder including a fixture configured to hold a radioactive source material in a two-dimensional geometric configuration;
- and
- the radioactive source material disposed in the fixture in the two-dimensional geometric configuration;
- wherein the holder further comprises a plate and the fixture comprises a channel disposed along the edges of the plate.
A calibration rig for an imaging system comprising:
- a base;
- a holder extending from the base, the holder including a fixture configured to hold a radioactive source material in a two-dimensional geometric configuration;
- and
- the radioactive source material disposed in the fixture in the two-dimensional geometric configuration;
- wherein the radioactive source material extends discontinuously from a first end to a second end of the two-dimensional geometric configuration.
A calibration rig for an imaging system comprising:
- a base;
- a holder extending from the base, the holder including a fixture configured to hold a radioactive source material in a two-dimensional geometric configuration;
- and
- the radioactive source material disposed in the fixture in the two-dimensional geometric configuration;
- wherein the geometric configuration comprises a triangle.
A calibration rig for an imaging system comprising:
- a base;
- a holder extending from the base, the holder including a fixture configured to hold a radioactive source material in a two-dimensional geometric configuration;
- and
- the radioactive source material disposed in the fixture in the two-dimensional geometric configuration;
- wherein the geometric configuration includes an asymmetry.
A molecular imaging system comprising:
- a frame;
- two cameras mounted on the frame, each camera comprising a radioactive source detector;
- and
- a calibration rig disposable between the two cameras, the calibration rig comprising a base, a holder extending from the base, the holder including a fixture configured to hold a radioactive source material in a two-dimensional geometric configuration, and the radioactive source material disposed in the fixture in the two-dimensional geometric configuration;
- wherein the cameras are mounted parallel to each other and each camera includes a pixelated detector and a collimator, the collimator comprising holes aligned with pixels on the camera, the holes of each collimator disposed at a non-parallel angle to the holes of the other collimator.
A molecular imaging system comprising:
- a frame:
- two cameras mounted on the frame, each camera comprising a radioactive source detector;
- and
