Abstract Objective. Protons have advantageous dose distributions and are increasingly used in cancer therapy. At the depth of Bragg peak range, protons produce a mixed radiation field consisting low- high-linear energy transfer (LET) components, latter which is characterized by an increased ionization density on microscopic scale associated with biological effectiveness. Prediction yield LET primary secondary charged particles at certain patient performed Monte Carlo simulations but...
Abstract The miniaturized radiation camera MiniPIX TPX3 is designed for detailed and wide-range measurements of mixed-radiation fields present in many applications such as radiotherapy space outer orbit. highly integrated instrumentation utilizes a single connector control readout flexible quick deployment. device features an option to process the registered data on same with limited resolution basic particle-type resolving power. A novel processing technique exploits detector high...
The Jagiellonian PET (J-PET) technology, based on plastic scintillators, has been proposed as a cost effective tool for detecting range deviations during proton therapy. This study investigates the feasibility of using J-PET monitoring by means detailed Monte Carlo simulation 95 patients who underwent therapy at Cyclotron Centre Bronowice (CCB) in Krakow, Poland. 
Approach: Discrepancies between prescribed and delivered treatments were artificially introduced simulations shifts patient...
Mixed-radiation fields in environments such as particle radiotherapy and outer space exhibit large complexity terms of composition spectral distribution which are difficult to measure detail. For this purpose, we present a high-sensitivity technique using the pixel detector Timepix3 spectral-tracking characterization secondary produced proton radiotherapy. Particle-event classes resolved into broad groups high-energy transfer particles (HETPs), protons, ions, neutrons, well low-energy...
This paper reports on the implementation and shows examples of use ProTheRaMon framework for simulating delivery proton therapy treatment plans range monitoring using positron emission tomography (PET). offers complete processing plans, patient CT geometries, intra-treatment PET imaging, taking into account imaging coordinate systems activity decay during protocol specific to a given facility. We present illustrate its potential case data steps treated at Cyclotron Centre Bronowice (CCB)...
Abstract The semiconductor pixel detector Timepix2 is operated with highly integrated readout electronics as a miniaturized and portable MiniPIX TPX2 radiation camera for imaging spectral-sensitive particle tracking in wide field-of-view. device provides room-temperature operation, ease of use (single USB 2.0 port), online response single track visualization, fast frame (up to 60 fps) double per-pixel detailed measurements energy counting or timing sensitivity. We evaluate the applicability...
A precise characterization of therapeutic proton pencil beams is essential for commissioning any treatment planning system (TPS). The dose profile includes measurement the beam lateral in core and far from core, so called low-dose envelope, requires a sophisticated detection with few orders magnitude dynamic range. We propose to use single-quantum sensitive Minipix Timepix detector, along an in-house designed holder perform measurements air water. validated manufacturer calibration detector...
Objective: The aim of this work is to investigate the feasibility Jagiellonian Positron Emission Tomography (J-PET) scanner for intra-treatment proton beam range monitoring. Approach: Monte Carlo simulation studies with GATE and PET image reconstruction CASToR were performed in order compare six J-PET geometries (three dual-heads three cylindrical). We simulated irradiation a PMMA phantom Single Pencil Beam (SPB) Spread-Out Bragg Peak (SOBP) various ranges. sensitivity precision each...
