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…

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…
