1. RAPID DETECTION OF VITAMIN C CONTENT IN FRUITS AND VEGETABLES USING A DIGITAL CAMERA AND COLOR REACTION
In this study, we propose a novel method to determine the vitamin C content in fruits and vegetables. The proposed method exploits the image and data processing abilities of computers by coupling a digital camera and a color reaction. An image acquisition device was developed to collect the image information of the solution to be measured after the color rea

3. Evaluation of the Spies™ modalities image quality
Introduction The Spies™ system (Karl-Storz®) was introduced into digital ureteroscopy to improve endoscopic vision. To date, there is no data to either indicate which of the Spies modalities is better for improving diagnosis and treatment procedures, nor to compare the modalities in terms of image quality. The aim of this study was to evaluate and compa

4. Breast density pattern characterization by histogram features and texture descriptors
Abstract Introduction Breast cancer is the first leading cause of death for women in Brazil as well as in most countries in the world. Due to the relation between the breast density and the risk of breast cancer, in medical practice, the breast density classification is merely visual and dependent on professional experience, making this task very subjective

5. Efficacy Analysis of a Script-based Guide for EVAR Execution: is it Possible to Reduce Patient Exposure to Contrast, Operative Time and Blood Loss even when Advanced Technologies are not Available?
ABSTRACT INTRODUCTION: Despite the patient and medical staff exposure to radiation in endovascular aneurysm repair, the benefits of this abdominal aortic aneurysm type of surgical management are justfied by minor recovery time and hospitalization, as well as an option for patients not elected to conventional open repair. In this minimally invasive surgical

8. Segmentação das áreas isquêmicas no acidente vascular cerebral utilizando imagens de tomografia computadorizada de perfusão / Segmentation of ischemic areas in stroke using perfusion computed tomography images
The techniques of digital image processing have been widely applied to medical imaging. One of the benefits brought about by these tools is to provide measurements of parameters that are difficult to estimate and likely to bias the physician. This study aimed to develop semi-automatic software of segmentation of the ischemic areas, core and penumbra in strok

10. Fibras elásticas da parede abdominal anterior em pacientes com hérnia ventral / Elastic fibers from the anterior abdominal wall in patients with ventral hérnias
In the present study samples were collected from abdominal linea alba aponeurosis of 30 patients (15 males and 15 females) aged from twenty to sixty years [30-59], (Mean=44.9±SD=7.3), with hernia of the anterior abdominal wall to evaluate the immunohistochemistry expression and morphometry of the elastic fibers. Nine of the patients were submitted to surger
