Tomographic pet camera with adjustable diameter detector ring |
摘要 |
A PET camera is disclosed with radially translating detector segments coupled with a rotational motion to tailor the camera detector ring to the size of the subject for optimal detection efficiency. In particular methods of using the present invention, the detector segments may be radially translated to describe a small diameter in imaging a small object, such as a breast. Alternately, the detectors may comprise a large diameter to image a large object, such as body. The detector segments may be diametrically opposed for optimal positron detection. The present invention may be coupled with a quadrant-sharing-photomultiplier-detector design.
