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.
