PATIENT DISPLAY SYSTEM FOR A MEDICAL IMAGING OR RADIOTHERAPY APPARATUS
20220125395 · 2022-04-28 ·

A medical imaging and/or radiotherapy apparatus incorporates a display for projecting a visible image to a patient lying on a patient table. A projector that projects the visible image moves in tandem with the patient table, so that it appears relatively motionless to the patient. In exemplary embodiments, the projector projects the visible image within a patient tunnel of the medical apparatus, including in some embodiments, an extended field of view medical imaging apparatus. In other exemplary embodiments, the projector projects the visible image on a screen above the patient table of a tunnel-less medical apparatus. The projector remains outside the imaging line of response of detectors within the imaging field or outside of the radiotherapy beam zone, to avoid potential degradation of the captured diagnostic image or degradation of the radiotherapy beam.
