Adaptive method for multicriteria optimization of intensity‐modulated proton therapy

Medical Physics, 2018
PurposeProvide an adaptive multicriteria optimization (MCO) method for intensity‐modulated proton therapy (IMPT) utilizing GPU technology. Previously described limitations of MCO such as Pareto approximation and limitation on the number of objectives were addressed.MethodsThe treatment planning process for IMPT must account for multiple objectives ...

Comparison and evaluation of different deep learning models of synthetic CT generation from CBCT for nasopharynx cancer adaptive proton therapy.

Medical Physics (Lancaster), 2023
BACKGROUND Cone-beam computed tomography (CBCT) scanning is used for patient setup in image-guided radiotherapy. However, its inaccurate CT numbers limit its applicability in dose calculation and treatment planning.

Standardized review criteria improve the efficiency of verification CT workflows in adaptive proton therapy for head-and-neck cancers.

Medical Dosimetry
Patients treated with proton beam therapy (PBT) undergo routine verification CT (VCT) scans during their courses of treatment to evaluate anatomic variations and the potential need for revision planning.

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 ...

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.
