Precedence 6 Model # 882351 Product Usage: Precedence (cleared as Griffin) is an imaging system combining the acquisition of single photon nuclear medicine images and images from an x-ray computed tomography system. Precedence may produce non-attenuation corrected and attenuation corrected images of the distribution of radiopharmaceuticals in the body as well as x-ray transmission images. The CT transmission data may be used to produce attenuation corrected nuclear medicine images. The nuclear medicine images and the CT images may be registered and displayed in a fused format (overlaid in the same orientation) to provide combined single photon and anatomical data for anatomical localization of the nuclear medicine data. Precedence may be used either as a separate single photon system, a separate CT system or as a combined CT and single photon system. The nuclear medicine and CT images may be transferred to other systems such as a radiation therapy planning system. The Precedence Im
During collimator exchange, the alignment of the collimator cart and detectors may cause a collimator exchange fail, and a collimator may drop to the floor beside the collimator cart. The collimator may be partially supported by the cart (e.g. leaning against the cart), or it may fall/slide all the way to the floor.
