Independently Rotatable Detector Plate for Medical Imaging Device

摘要

A real-time fluoroscopic imaging system includes a collimator and a detector which are rotationally movable independent of the support assembly, e.g., c-arm, to which they are mounted. Rotational movement of the collimator and the detector are coordinated such that the orientation of the detector with respect to the collimator does not change. The collimator may include a geared flange member to facilitate rotation, and may be a single molded piece formed of a plastic such as tungsten polymer material. The system may also include a plurality of interchangeable collimators characterized by different shapes. A display is provided to present an image to an operator, and image orientation logic displays a target anatomy in a selected orientation regardless of orientation of the target anatomy relative to the detector, and regardless of rotation of the detector.

主权项

1. A fluoroscopic imaging device comprising:
a c-arm support assembly; an x-ray source assembly mounted at a first distal end of the c-arm support assembly; a detector assembly rotatably mounted to a second distal end of the c-arm support assembly, wherein the detector assembly is configured to rotate independently of the c-arm support assembly; and a collimator assembly rotatably mounted to the first distal end of the c-arm support assembly, wherein the collimator assembly is configured such that plane of rotation of the collimator assembly matches plane of rotation of the detector assembly.
