Claims27
A gamma radiation camera system, comprising;
- a gamma radiation imager having a field of view and having a first radiation sensitivity;
- and
- a gamma radiation detector having a sensitivity greater than that of the imager and facing in a same direction as a field of view of the imager.
A method of nuclear imaging comprising:
- providing a radiation imager having a field of view and having a first radiation sensitivity and a radiation detector having a sensitivity greater than that of the imager and facing in a same direction as a field of view of the imager;
- determining a direction for the imager based on a radiation signal from the detector.
A method of determining whether a cancerous lesion which has been tagged with a radionuclide, has been removed, comprising:
- acquiring a first nuclear image of an area including the cancerous lesion, prior to excision of the lesion;
- acquiring a second nuclear image of the area after excision of at least part of the lesion;
- and
- comparing the first and second images to each other,
- wherein the first and second nuclear images are acquired using a radiation camera that comprises:
- a radiation imager having a field of view and having a first radiation sensitivity;
- and
- a radiation detector having a sensitivity greater than that of the imager and facing in a same direction as a field of view of the camera.
