Abstract:

Techniques, apparatus and systems are disclosed for performing graphics processor unit (GPU)-based fast cone beam computed tomography (CBCT) reconstruction algorithm based on a small number of x-ray projections. In one aspect a graphics processor unit (GPU) implemented method of reconstructing a cone beam computed tomography (CBCT) image includes receiving, at the GPU, image data for CBCT reconstruction. The GPU uses an iterative process to minimize an energy functional component of the received image data. The energy functional component includes a data fidelity term and a data regularization term. The reconstructed CBCT image is generated based on the minimized energy functional component.

Abstract:

The present disclosure is directed towards a treatment planning system for use in a stereotactic radiotherapy system. In particular, the disclosed systems and methods may be used for generating a treatment plan and/or verifying an existing treatment plan. Moreover, the disclosed systems and methods may be suitable for use in a clinical setting. A method for verifying a treatment plan of a stereotactic radiotherapy device may include the steps of receiving a treatment plan, generating a second treatment plan by applying a modified monte-carlo method to regions of interest in the treatment plan, and identifying discrepancies between the received treatment plan and the generated second treatment plan.

Abstract:

A method and system for generating a treatment plan are disclosed herein. A computing system receives a plurality of dose volume histograms for a plurality of patients and a plurality of volumetric dose distributions corresponding to the plurality of dose volume histograms. The computing system generates a volumetric dose prediction model using a neural network by learning, by the neural network, a relationship between a plurality of dose volume histograms for the plurality of patients and the corresponding plurality of volumetric dose distributions. The computing system receives a candidate dose volume histogram for a target patient. The computing system infers, via the volumetric dose prediction module, a volumetric dose prediction distribution matching the candidate dose volume histogram. The computing system generates a recommendation based on the inferred volumetric dose prediction distribution.
