According to the World Health Organization, breast cancer is the most common type of cancer in women. It is also the second leading cause of death among women around the world, becoming the most fatal form of cancer. However, to detect and classify masses is a hard task even for experts. Therefore, due to medical experience, different diagnoses to an image are commonly found. The use of a computer...

The exposition of living tissues to ionizing radiation can result on several health problems, increasing the probability of cancer. Efforts from both academy and industry to develop and improve non-invasive methods have been increasing since the 1990's. Electrical Impedance Tomography (EIT) is a noninvasive imaging technique that offers a vast field of possibilities for imaging diagnostics, once it...
Most of the food consumed in Brazilian cities, as in other big urban spaces, is produced by family farming. The economic sustainability of these family communities depends on the range of primary health care. The rational use of medicinal plants is recognized by the World Health Organization (WHO) as an important element of healing practices and nutrition education. Mobile health applications can...
Non-invasive imaging and e-health have been increasing in the last decades, as a result of the efforts to generate diagnostic technology based on non-ionizing radiation. Electrical Impedance Tomography (EIT) is a low-cost, non-invasive, portable, and safe of handling imaging technique based on measuring the electric potentials generated by the application of currents in pairs of surface electrodes...
The basic health care level in Brazil's Unified Health System consists of a community-based attention model composed by small teams of health professionals dedicated to deal with low-complexity problems. Despite the social and economic advances experimented in the last two decades, social inequalities still persist in Brazilian countryside. However, smartphones and tablets are becoming more widespread...
It is a well-known fact that exposure of living tissues to ionizing radiation can result on several health problems, where cancer is probably the most complicated. This issue has been strengthening the efforts of both academy and industry to develop and improve non-invasive methods in the last decades. Electrical Impedance Tomography (EIT) is a non-invasive imaging technique that offers a vast field...
The fields of non-invasive imaging and e-health have been increasing in the last decades, due to the need of avoiding to exposure living tissues to ionizing radiation, increasing monitoring levels of critical patients, and promoting the increasing of quality life. Furthermore, the use of image-reconstruction devices based on ionizing radiation can result on several health problems for patients in...
Family farming is responsible for producing most of the food consumed in Brazil, occupying an important role in national development and at the reduction of social inequalities. The sustainability of these family communities depends heavily on the range of primary health care. The rational use of medicinal plants is recognized by the World Health Organization (WHO) as an important element of healing...
The level of basic care in Brazil’s Unified Health System is a community-based attention model composed by Family Health Units, small teams of health professionals intended to solve low-complexity problems at a territory delimitated by a certain number of families, attended by Communitary Health Agents. Despite the large amount of social inequalities in Brazilian countryside, smartphones and tablets...
The development and improvement of non-invasive imaging techniques have been increasing in the last decades, due to interests from both academy and industry. Electrical Impedance Tomography (EIT) is a noninvasive imaging technique that offers a vast field of possibilities due to its low cost, portability, and safety of handling. However, EIT image reconstruction is an ill-posed problem. Herein this...
About 8% of men are affected by color blindness. That population is at a disadvantage since they cannot perceive a substantial amount of the visual information. This work presents two computational tools developed to assist color blind people. The first one tests color blindness and assess its severity. The second tool is based on Fuzzy Logic, and implements a method proposed to simulate real red...
The Aedes Aegypti mosquito is the vector of the most difficult public health problems in tropical and semi-tropical world: the epidemic proliferation of dengue, a viral disease that can cause human beings death specially in its most dangerous form, dengue haemorrhagic fever. One of the most useful methods for mosquito detection and surveillance is the ovitraps: special traps to collect eggs of the...
Alzheimer's disease is the most common cause of dementia, yet hard to diagnose precisely without invasive techniques, particularly at the onset of the disease. This work approaches image analysis and classification of synthetic multispectral images composed by diffusion-weighted (DW) magnetic resonance (MR) cerebral images for the evaluation of cerebrospinal fluid area and measuring the advance of...
