Assessment of a Therapeutic X-ray Radiation Dose Measurement System Based on a Flexible Copper Indium Gallium Selenide Solar Cell

open access: yesSensors, 2022
Several detectors have been developed to measure radiation doses during radiotherapy. However, most detectors are not flexible. Consequently, the airgaps between the patient surface and detector could reduce the measurement accuracy.

Successful treatment with proton beam therapy for a solitary sternal metastasis of breast cancer: a case report

open access: yesJournal of Medical Case Reports, 2022
Background Breast cancer infrequently metastasizes to the sternum as solitary metastasis. We experienced successful treatment with proton beam therapy for a case of sternal metastasis of breast cancer.

Long-term survival after definitive proton beam therapy for oligorecurrent esophageal squamous cell carcinoma: a case report

open access: yesJournal of Medical Case Reports, 2022
Background Radical esophagectomy for esophageal squamous cell carcinoma has improved survival, but the rate of recurrence is high. Patients of recurrent esophageal squamous cell carcinoma after failure of chemotherapy have a poor prognosis.

Monitoring of breathing motion in image-guided PBS proton therapy: comparative analysis of optical and electromagnetic technologies

open access: yesRadiation Oncology, 2017
Background Motion monitoring is essential when treating non-static tumours with pencil beam scanned protons. 4D medical imaging typically relies on the detected body surface displacement, considered as a surrogate of the patient's anatomical changes, a ...

Long-term results of a phase II study of hypofractionated proton therapy for prostate cancer: moderate versus extreme hypofractionation

open access: yesRadiation Oncology, 2019
Background We performed a prospective phase II study to compare acute toxicity among five different hypofractionated schedules using proton therapy. This study was an exploratory analysis to investigate the secondary end-point of biochemical failure-free

Proton-counting radiography for proton therapy: a proof of principle using CMOS APS technology [PDF]

open access: yes, 2014
Despite the early recognition of the potential of proton imaging to assist proton therapy (Cormack 1963 J. Appl. Phys. 34 2722), the modality is still removed from clinical practice, with various approaches in development. For proton-counting radiography

Treatment outcomes of passive scattering proton beam therapy for stage I non-small cell lung cancer

open access: yesRadiation Oncology, 2021
Introduction To investigate the treatment outcomes of passive scattering proton beam therapy using stereotactic ablative radiotherapy (SABR) or hypofractionated radiation therapy (RT) for inoperable patients or those who refused surgery for stage I non ...
