This study proposes an innovative methodology that combines experimental microCT imaging with Monte Carlo irradiation simulations using the PENELOPE code aimed at enabling detailed analyses of different features involved in processes along elemental mapping, as required for X-ray fluorescence vivo samples. By examining relationship between signal-to-noise ratio (SNR) and absorbed dose (D), a mathematical approach was proposed to determine critical points where their rates change are equal....
Abstract Purpose Absorbed dose calculation by kernel convolution requires the prior determination of point kernels (DPK). This study reports on design, implementation, and test a multi-target regressor approach to generate DPKs for monoenergetic sources model obtain beta emitters. Methods DPK electron were calculated using FLUKA Monte Carlo (MC) code many materials clinical interest initial energies ranging from 10 3000 keV. Regressor Chains (RC) with three different coefficients...
The present work focuses on the behavior of stopping power a polymer gel dosimetry system, known as PAGAT,infused with high atomic number nanoparticles formed by gold, 1 % mass concentration. study is carried out for different energies electron and proton beams within ranges therapeutic applications, first theoretical assessment, then simulation Monte Carlo codes: PENELOPE in case electrons, FLUKA protons. results obtained analytically show promising gold nanoparticle infused...
Absorbed dose calculation by kernel convolution requires the prior determination of point kernels (DPK). This study shows applications machine learning to generate DPKs for monoenergetic sources and a model obtain beta emitters.
Nowadays, nuclear medicine procedures have become a standard for several pathologies, both diagnosis and therapeutic purposes. Also, regarding applications, the demand novel techniques new radioisotopes is increasing worldwide. Due to high dose rates involved in therapy procedures, this aspect requires significant efforts related development of more accurate methods protocols individualized patient dosimetry estimations. New theranostic allowing joint diagnosis/treatment implementation...
Monoclonal labeled antibodies are commonly used for radioimmunotherapy purposes in nuclear medicine The procedure is based on the deposition of specific radiactivity concentrations tumoral regions with aim treating diseases.Patient metabolism produces nonuniform organ activity distributions, but there some traditional approaches internal dosimetry assuming uniform spatial distribution within or tissues interest.When patient-specific needs to be performed, these methods may involve non...
The overall quantity of nuclear medicine procedures has increased remarkably in recent years, making them a daily tool capable reaching wide sectors the population. Regarding therapeutic applications, it is worth noting that there an increasing demand novel techniques and greater variety radioisotopes requiring accurate patient-specific dosimetry aimed at evaluating lethal damage to tumor while maintaining acceptable dose levels healthy tissues. Image-guided internal appears as particularly...
