To introduce a new algorithm -MicroCalc- for dose calculation by modeling microdosimetric energy depositions and the spectral fluence at each point of a particle beam. Proton beams are considered as a particular case of the general methodology. By comparing the results obtained against Monte Carlo computations we aim to validate the microdosimetric formalism presented here and in previous works.

This work introduces the concept of segment-averaged linear energy transfer (LET) as a new approach to average distributions of LET of proton beams based on a revisiting of microdosimetry theory. The ...
The Fast Dose Calculator (FDC), a track repeating Monte Carlo algorithm was initially developed for proton therapy. The validation for proton therapy has been demonstrated in a previous work. ...
Positron emission tomography (PET) has been extensively studied and clinically investigated for dose verification in proton therapy. However, the production distributions of positron emitters are not ...
The dose core of a proton pencil beam (PB) is enveloped by a low dose area reaching several cm off the central axis and containing a considerable amount of the dose. Adequate modeling of the different...
Technical Note: Treatment Planning System (TPS) Approximations Matter ─ Comparing Intensity Modulated Proton Therapy (IMPT) Plan Quality and Robustness between a Commercial and an In-house Developed TPS for Non-Small Cell Lung Cancer (NSCLC).
Approximate dose calculation methods were used in the nominal dose distribution and the perturbed dose distributions due to uncertainties in a commercial treatment planning system (CTPS) for robust op...
Researchers want to compare proton stopping ratios, used for proton beam therapy planning, calculated based on single energy CT and dual energy CT images; with the intension of improve upo...
In patients with a walnut allergy double blind placebo controlled food challenge with walnut will be combined with the intake of proton pump inhibitor (PPI) or with placebo to assess the i...
The purpose of this study is to see what effects, good and/or bad, image guided proton based radiation combined with low dose chemotherapy and hormonal therapy has on you and your cancer.
Primary Objectives: To establish the efficacy of proton beam therapy with or without photon beam radiation therapy for skull base chordoma. Secondary Objectives: 1. To det...
Proton therapy is a limited medical resource that is more expensive than conventional x-ray therapy. To correctly measure the success of proton therapy in treating different conditions, i...
CONFORMAL RADIOTHERAPY that combines several intensity-modulated beams to provide improved dose homogeneity and highly conformal dose distributions.
The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
The use of an external beam of PROTONS as radiotherapy.
A complex of enzymes and PROTON PUMPS located on the inner membrane of the MITOCHONDRIA and in bacterial membranes. The protein complex provides energy in the form of an electrochemical gradient, which may be used by either MITOCHONDRIAL PROTON-TRANSLOCATING ATPASES or BACTERIAL PROTON-TRANSLOCATING ATPASES.
Work that consists of a conference of physicians on their observations of a patient at the bedside, regarding the physical state, laboratory and other diagnostic findings, clinical manifestations, results of current therapy, etc. A clinical conference usually ends with a confirmation or correction of clinical findings by a pathological diagnosis performed by a pathologist. "Clinical conference" is often referred to as a "clinico-pathological conference."
