PATIENT POSITION CONTROL FOR COMPUTED TOMOGRAPHY DURING MINIMALLY INVASIVE INTERVENTION

摘要

Computed tomography is used during a minimally invasive intervention. A processor detects the inserted device (e.g., catheter) from a CT scan of the patient. The bed and/or gantry of the CT are moved based on the detected location of the inserted device. As the device is moved within the patient, the automatic detection is used to continue to adjust the CT field of view to scan the device. To further assist the intervention, combining scans with different fields of view relative to the patient may generate an extended field of view image.

主权项

1. A method for use of computed tomography during minimally invasive intervention, the method comprising:
scanning a first region of a patient with a computed tomography scanner while the patient is on a bed and while a minimally invasive object is within the patient; detecting the minimally invasive object in data resulting from the scanning of the first region; altering a position of the bed, of a gantry of the computed tomography scanner, or both the bed and the gantry based on a location of the detected minimally invasive object; and scanning a second region of the patient different than the first region due to the altering.
