  • Publication number: 20250010103
    Abstract: Techniques for detecting real-time proton beam dose include retrieving conversion data for converting proton dose to acoustic pressure based on medical imagery. 3D medical imagery is retrieved of a first region of interest (ROI) inside a first subject. A real-time signal indicates ultrasound pressure at a 2D ultrasound array disposed outside and in contact with the first subject close to the first ROI. Real-time 3D dose delivered in the first ROI is determined by inputting the real-time signal into a dose detection module that includes a neural network. The neural network is trained on multiple instances of a training set. Each instance includes: simulated proton dose delivered to a similar ROI inside a second subject; simulated pressure generation from that simulated dose based on the conversion data and a similar 3D medical image; and simulated acoustic transmission from the similar ROI to a similar two-dimensional ultrasound transducer array similarly disposed.
