Local treatment failure after globe-conserving therapy for choroidal melanoma. [PDF]

, 2013
Local treatment failure after globe-conserving therapy for choroidal melanoma is a surgical complication with significant morbidity to the vision and eye. Few reports in the literature have addressed this complication exclusively.

Evaluation of resistive-plate-chamber-based TOF-PET applied to in-beam particle therapy monitoring [PDF]

, 2015
Particle therapy is a highly conformal radiotherapy technique which reduces the dose deposited to the surrounding normal tissues. In order to fully exploit its advantages, treatment monitoring is necessary to minimize uncertainties related to the dose ...

On the accuracy of Monte Carlo based beam dynamics models for the degrader in proton therapy facilities

, 2018
In a cyclotron-based proton therapy facility, the energy changes are performed by means of a degrader of variable thickness. The interaction of the proton beam with the degrader creates energy tails and increases the beam emittance.

Dosimetric evidence confirms computational model for magnetic field induced dose distortions of therapeutic proton beams

, 2017
Given the sensitivity of proton therapy to anatomical variations, this cancer treatment modality is expected to benefit greatly from integration with magnetic resonance (MR) imaging.

Proton beam therapy for liver cancers [PDF]

Journal of Gastrointestinal Oncology, 2020
Proton beam therapy (PBT) delivers less dose to nearby normal organs compared to X-ray therapy (XRT), which is particularly relevant for treating liver cancers given that both mean and low liver dose are among the most significant predictors of radiation induced liver disease (RILD).

Proton beam therapy for a giant hepatic hemangioma: A case report and literature review

Clinical and Translational Radiation Oncology, 2021
Background: Hepatic hemangiomas are benign tumors with a favorable prognosis, but giant hepatic hemangiomas can cause abdominal symptoms and are indicated for treatment. Most cases are treated with surgery, but radiotherapy has also been used.
