GPU‐accelerated Monte Carlo‐based online adaptive proton therapy: A feasibility study

Medical Physics, 2022
AbstractPurposeTo develop an online graphic processing unit (GPU)‐accelerated Monte Carlo‐based adaptive radiation therapy (ART) workflow for pencil beam scanning (PBS) proton therapy to address interfraction anatomical changes in patients treated with PBS.Methods and MaterialsA four‐step workflow was developed using our in‐house developed GPU ...

Photon-counting CBCT iterative reconstruction for adaptive proton therapy

15th International Meeting on Fully Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine, 2019
Cone beam computed tomography (CBCT) is used to determine a patient position in proton therapy, but its image quality is low compared to that of a conventional CT because data measured by a two-dimensional detector used in CBCT contain scattered X-ray components.

Online Adaptive Proton Therapy Facilitated by Artificial Intelligence-Based Autosegmentation in Pencil Beam Scanning Proton Therapy

International Journal of Radiation Oncology*Biology*Physics
Online adaptive proton therapy (oAPT) is essential to address interfractional anatomical changes in patients receiving pencil beam scanning proton therapy. Artificial intelligence (AI)-based autosegmentation can increase the efficiency and accuracy.

Toward adaptive proton therapy guided with a mobile helical CT scanner

Radiotherapy and Oncology, 2018
To evaluate the feasibility of image-guided adaptive proton therapy (IGAPT) with a mobile helical-CT without rails.CT images were acquired with a 32-slice mobile CT (mCT) scanning through a 6 degree-of-freedom robotic couch rotated isocentrically 90 degrees from an initial setup position.

Optimization of proton and heavy ion therapy using an adaptive inversion algorithm

Radiotherapy and Oncology, 1989
In order to fully utilize the dose distributional advantages of pions, protons and heavy ions it is important to cover the target volume as well as possible by Bragg peaks and avoid irradiating surrounding organs at risk. The most general way to achieve this goal is by modulation of the range of the beam so that its Bragg peak falls exclusively in the ...
