Abstract
A system and method for providing emission mammography are provided. The system includes a first gamma emission detector and a second gamma emission detector. The first and second gamma emission detectors are configured to compress an object therebetween. The system further includes a radioactive transmission source. At least one of the first and second gamma emission detectors is configured to detect gamma ray photons from the radioactive transmission source.
Claims27
A medical imaging system comprising:
- a first cadmium zinc telluride (CZT) gamma detector;
- a second CZT gamma detector, the first and second CZT gamma detectors configured to compress an object therebetween to immobilize the object and detect emission photons;
- and
- a gantry configured for rotation, the gantry further configured to support the first CZT gamma detector, the second CZT gamma detector and a transmission source, the gantry providing variable positioning of the first CZT gamma detector, wherein the first CZT gamma detector is coupled to the gantry and configured for movement along the gantry and the second CZT gamma detector is fixedly held to the gantry.
A quantitative emission mammography conjugate-view imaging system comprising:
- a first gamma detector coupled to a gantry and configured for movement along the gantry;
- a second gamma detector fixedly held to the gantry, the first gamma camera variably positionable with the movement to compress a breast between the first gamma detector and the second gamma detector to immobilize the breast therebetween;
- a translatable radioactive transmission source, at least one of the first and second gamma detectors configured to detect gamma ray photons from the radioactive transmission source;
- a shielded receptacle for storing the translatable radioactive transmission source;
- and
- a calibration source coupled generally along an end of a field of view of the first and second gamma cameras.
A method for performing diagnostic imaging, the method comprising:
- detecting emission photons utilizing a first cadmium zinc telluride (CZT) gamma detector and a second CZT gamma detector, the first and second CZT gamma detectors configured to compress an object therebetween to immobilize the object, wherein the first CZT detector is movable relative to a gantry and the second CZT gamma detector is fixedly held to the gantry;
- and
- detecting transmission photons from a radioactive transmission source utilizing the first and second CZT gamma detectors.
A quantitative emission mammography conjugate-view imaging system comprising:
- a first gamma camera coupled to a gantry and configured for translation relative to the gantry;
- a second gamma camera fixedly held to the gantry, the first gamma camera variably positionable with the translation to compress a breast between the first gamma camera and the second gamma camera;
- and
- a processor, configured to receive a first emission image from the first gamma camera and a second emission image from the second gamma camera and calculate quantitative distribution of radiopharmaceutical isotope in the breast based on the received first and second images and the thickness of the lightly compressed breast.
