摘要： Various methods and systems are provided for collision avoidance in cone-beam computed tomography (CT) systems. In one embodiment, a method for an imaging apparatus comprises calculating a likelihood of a collision between the imaging apparatus and a subject and/or its support based on a model of the subject, performing a scan of the subject responsive to the likelihood below a threshold, and not performing the scan otherwise. In this way, collisions between the patient and the imaging apparatus can be avoided.

摘要： An interventional device configured for placement in or near an internal organ or tissue is provided. The interventional device includes a reference portion having three or more sensor elements. In one implementation, the interventional device and associated sensor elements provide dynamic referencing of the internal organ, tissue or associated vasculature after registration of the sensor data with images and/or volumetric representations of the internal organ or tissue.

摘要： Systems and methods of object reconstruction from x-ray imaging include receiving an input of a first angulation for a first x-ray image. A first score representative of a quality of a reconstruction of an object from an x-ray image acquired at the first angulation is calculated. The first x-ray image is acquired at the first angulation. An input of a second angulation for a second x-ray image is received. A second score representative of the quality of the reconstruction of the object from the first x-ray image and an x-ray image acquired at the second angulation is calculated. The second x-ray image is acquired at the second angulation. The object is reconstructed from the first x-ray image and the second x-ray image.
