PhD in Nuclear Technology and Specialist in Diagnostic Physics by ABFM. Currently an Associate Professor in the Department of Nuclear Physics at the Institute of Physics of USP. Has experience in the field of Medical Physics, working mainly on the following topics: development of radiologically tissue-equivalent materials, radiation protection, computed tomography, quality control in diagnostic imaging, and X-ray spectrometry. He is a faculty member and vice-coordinator of the Medical Physics Residency Program in the Diagnostic Imaging modality at the Department of Radiology and Oncology of the USP School of Medicine. He is a full member of the Coordinating Committee for the Bachelor's Degree in Medical Physics at IFUSP/FMUSP, the Medical Physics Committee of SBF, and the Deliberative Council of ABFM. Member of the Global Research and Scientific Innovation Committee and the Hispanic and Latin-x Medical Physics Subcommittee of AAPM. He has been a member of the Education and Training Committee of IOMP and the Radiation Protection Committee of CBR. He is a full member of SBF, ABFM, and AAPM. He was President of ABFM in the 2008-2009 term and has served multiple terms on the Deliberative Council. Father of Pedro (2009) and Ingrid (2019). (Source: Lattes Curriculum)

In the last two decades, X-ray computed tomography (CT) has become one of the most important diagnostic imaging methods. The efficiency of the CT technique has increased its popularity around the world. Thus, the development of global dose assessments and procedural optimizations are important tasks. Recent works have established important associations between Figures of Merit (FOM's) and…
The prof. Arreola develops research in the Department of Radiology of the University of Florida College of Medicine of significant importance in different areas of Medical Physics and Radiation Dosimetry. Some that were published in important scientific journals and involve the quantification of doses in techniques of computed tomography, mammography and fluoroscopy. Consirering his exper…
Tissue-equivalent materials, or phantoms, are used in research laboratories and in clinical settings as part of quality control and radioprotection routines and are critical to avoid exposing people to unnecessary radiation doses. Currently there are around 127,000 diagnostic imaging equipment distributed throughout the country and, according to the current legislation, all should be subj…

The quantity of Computed Tomography (CT) scans performed in Brazil and worldwide has been increasing, given the capacity of this medical imaging modality to represent the internal structures of the human body quickly, efficiently, and non-invasively. The state of São Paulo possesses the highest number of CT equipment in Brazil, which makes evident the need for the development of studies i…
In Brazil, currently indispensable measuring instruments for the activities of quality control and dosimetry of medical equipment, such as ionization chambers, voltage and time of exposure meters, as well as the phantoms are mostly imported and of high cost. In addition, the few national materials available do not cover all the needs of the internal market in this area, reinforcing the ne…
Estimates of mean glandular dose are made from external breast measuring and, in practical situations, externally to a phantom representing a typical breast. The estimate of the mean glandular dose is obtained from results of the Monte Carlo method, which considers specific measuring architectures and that must be reproduced by the measuring process in question. Correlations between this …
The dosimetric measurement quantities currently adopted by national regulation or to standardization of dosimetric models adopted by CT equipment manufacturers are based in a metric, introduced around thirty years ago: the Computed Tomography Dose Index (CTDI). This quantity, apart from its variations on definition, represents the absorbed dose along the longitudinal axis of an acrylic ph…

Recent literature identify to the need to improve methods for optimizing low-dose computed tomography (LDCT) procedures using physical and observational metrics to enable the reduction of radiation doses while maintaining or improving image quality. This project proposes the investigation of methods for qualifying low-dose tomographic images (LDCT) that take into account physical and obse…
