Monte Carlo dosimetry of a realistic multicellular model of follicular lymphoma in a context of radioimmunotherapy
(2020)
Purpose
Small-scale dosimetry studies generally consider an artificial environment where the tumors are spherical and the radionuclides are homogeneously biodistributed. However, tumor shapes are irregular and radiopharmaceutical ...
Modelling SPECT auto-contouring acquisitions for 177Lu & 131I molecular radiotherapy using new developments in Geant4/GATE
(2022)
Purpose
Monte Carlo modelling of SPECT imaging in Molecular Radiotherapy can improve activity quantification. Until now, SPECT modelling with GATE only considered circular orbit (CO) acquisitions. This cannot reproduce ...
Clinical implementation of PLANET® Dose for dosimetric assessment after [177Lu]Lu-DOTA-TATE: comparison with Dosimetry Toolkit® and OLINDA/EXM® V1.0
(2021)
The aim of this study was to compare a commercial dosimetry workstation (PLANET® Dose) and the dosimetry approach (GE Dosimetry Toolkit® and OLINDA/EXM® V1.0) currently used in our department for quantification of the ...
Dosimeter arrangement for effective dose and isodose curves desterminations into craniofacial cavity
Disposición de dosímetros para determinaciones de curvas de dosis e isodosis efectivas en la cavidad craneofacial
(2023)
Tomographic dental imaging with cone beam computed tomography has developed so fast in Costa Rica, in the absence of investigations to determine the absorbed dose by the patients, we propose a TLD dosimeter array into RANDO ...
Improvement of early detection of breast cancer through collaborative multi-country efforts: Medical physics component
(2018)
Purpose: The International Atomic Energy Agency (IAEA) through a Coordinated Research Project on “Enhancing
Capacity for Early Detection and Diagnosis of Breast Cancer through Imaging”, brought together a group of mammography ...
QA Programme of the TLD laboratory of the University of Costa Rica: IEC 61066 testing
(2008)
The Thermoluminescence Personal Dosimetry Laboratory of the University of Costa Rica provides dose measurements for around 90% of occupational radiation workers in the country. The assessment of doses to workers routinely ...
Evaluation of [18F] FNM biodistribution and dosimetry based on whole-body PET imaging of rats
(2018)
Introduction: The aim of this work was to study the biodistribution, metabolism and radiation dosimetry of rats
injected with [18F]FNM using PET/CT images. This novel radiotracer targeting NMDA receptor has potential ...
Implementation of patient dosimetry in the clinical practice after targeted radiotherapy using [177Lu-[DOTATO,Tyr3]-octreotate
(2018-11-29)
Background: This study’s aim was to develop our dosimetric methodology using a commercial workstation for the
routine evaluation of the organs at risk during peptide receptor radionuclide therapy (PRRT) with 177Lu.
Methods: ...
Biological and dosimetric evaluation of [11C]S-adenosyl methionine as a potential agent for prostate cancer diagnosis
(2018)
Introduction: [11C]Choline ([11C]COL) has been widely used for prostate cancer diagnosis; however, this
radiopharmaceutical is not recommended for patients with a low absolute PSA value (< 1 ng/mL) due to its
limited ...
Converging science and literature cultures: learning physics via The Little Prince novella
(2018)
Primary level education follows a pedagogy model where literature and science have been historically separated. Natural children processes are disrupted, as learning based on play curiosity is completely transformed by a ...
