He is electronic engineer by University of S. Paulo (1986), and has master degree at Electrical Engineering (1988) and PhD at Applied Physics from University of S. Paulo (1992). Currently he is associate professor at the Escola de Engenharia de S.Carlos, University of S. Paulo. His research experience is in the Biomedical Engineering field, mainly with medical imaging, working with: mammography image processign, mammography, computer-aided diagnosis, medical image digitization and quality assurance in radiology. He worked as coordinator in the Master/Doctor degrees course in Electrical Engineering (2004-2006) as well as in the Electrical Engineering undergraduate course (2009-2015) at EESC/USP, and was also vice-director of the Informatics Center of S.Carlos, USP (2006-2013) (Source: Lattes Curriculum)

The availability of computational tools - from simplest to most complex - to aid in diagnostic radiology is already a reality, becoming in many cases an intrinsic resource of the process. In the field of mammography, these tools have been gathered into schemes called computer-aided detection / diagnosis (CADe / CADx), which have been proposed in order to reduce the difficulties of evaluat…
International quality agencies regulators of X-ray systems, such as the International Atomic Energy Agency (IAEA), have recently implemented protocols for acceptance testing of digital mammography equipment and breast tomosynthesis, with purposes of establishing a quality standard in radiological services. However, the established guidelines are based on the use of phantoms with standardi…
Recent preliminary tests with radiologists on a prototype of a CADx (Computer-aided Diagnosis) scheme in mammography, developed previously by our team, have shown that their results are able to positively influence the medical report - especially regarding the interpretation of suspicious findings on laboratory controlled evaluations. Furthermore, such evaluations also indicate that syste…
This work aims to propose a model involving digital subtraction of images aquired at different X-ray energy levels. The purpose is to allow the detection of malignant breast lesions which, in the conventional exam form, would be totally hidden when superimposed by tissues of similar absorption characteristics. This research is addressed to dense breast cases, which are commonly poor in co…

Aiming to deal with the clinical worsening of breast cancer as well as to assist its early detection, many imaging diagnosis procedures have been developed or improved regarding both the image and the equipment. Modules of mammography CADx (Computer aided diagnosis) schemes have been proposed with the aim of providing diagnostic support, improving its accuracy. Among the available screeni…
The increase in the number of new breast cancer detections is also increasing the developments of CAD schemes modules in order to provide better accuracy in mammography diagnosis. However, the most of researches in this field have been designed to detect or to classify primary features in mammographic images, as suspect masses and microcalcifications. Asymmetric regions have been consider…
The increase in breast cancer cases has taken attention of many specialists in several fields. One of the consequences of this feature is the development of CAD schemes designed to aid in obtaining more accurate diagnosis in mammography evaluation. In this field the efforts in aiding the detection and characterization of nodules and/or microcalcifications in mammography images has been gr…

The screening techniques are very important for the early detection of breast cancer. The main difficulties are: subjectivity of the specialist to determine the lesion characteristics (boundaries and texture, for example) and when they the lesions are not seen in certain image modality, such as radiographically dense breasts in mammography or when there are the occurrence of overlapping t…
