Abstract: The present disclosure relates to a hybrid continuous positive pressure and surface imaging system for use in a radiotherapy system, including: a positive pressure unit adapted to apply a continuous positive pressure to lungs of a patient during radiotherapy; a surface camera system configured to continuously, or at intervals, capture body surface images of the patient; and a processing unit configured to continuously, or at intervals, model chest and/or abdominal movement of the patient in response to the applied continuous positive pressure based on the body surface images. The disclosure further relates to a computer-implemented method of providing real-time feedback to a positive pressure unit.

Abstract: Apparatus for performing a procedure at a target site of a patient's body, the apparatus comprising: a continuous positive airway pressure (CPAP) apparatus that provides CPAP to the patient's lungs; a medical device for performing the procedure at the target site; and a controller that controls the CPAP apparatus to provide CPAP to the patient's lungs during performance of the procedure.

Abstract: A method for fusing a pre-operative MRI prostate image to an intra-operative TRUS or CT prostate image according to a least-cost affine transformation of the MRI contour onto the TRUS or CT contour, with smooth non-linear warping adjustment. MRI and CT processing may be performed as a pre-operational procedure for increased efficiency, while TRUS may be performed concurrent with a surgical procedure.
