This paper presents the Rehab@home system, a tool specifically developed for helping neurological patients performing rehabilitation exercises at home, without presence of physiotherapist. It is centred on balance and sit-to-stand (STS) movement.Rehab@home composed two Wii boards, webcam computer, it has main software applications: one to perform another therapists visualize data exercises. During exercises, from boards are processed in order automatically assess correctness...
An accurate detection of the macular edema (ME) presence constitutes a crucial ophthalmological issue as it provides useful information for identification, diagnosis and treatment different relevant ocular systemic diseases. Serous Retinal Detachment (SRD) is particular type ME, which characterized by leakage fluid that has propensity being accumulated in region. This paper proposes new methodology automatic identification characterization SRD using Optical Coherence Tomography (OCT) images....
Ovarian cancer is one of the most commonly occurring in women. Transvaginal ultrasound used as a screening test to detect presence tumors but, for specific types ovarian tumors, malignancy can only be asserted through surgery. An automatic method perform detection and assessment these tumours thus necessary prevent unnecessary oophorectomies.This work explores U-Net's architecture investigates selection different hyperparameters ovary follicles segmentation. The effect applying...
The purpose of the research herein presented is automatic delimitation lung fields in posterior-anterior digital chest radiographs. In a computer-aided diagnosis system precise location lungs important as it allows reduction region under analysis, decreasing computation time and facilitating data compression. Furthermore, search area, easing selective tuning abnormalities detection algorithms. results produced by method were validated comparison with manual contours traced experienced...
The detection of ovarian structures from ultrasound images is an important task in gynecological and reproductive medicine. An automatic system can work as a second opinion for less experienced physicians or complex interpretations. This presents study three popular CNN-based object detectors applied to the healthy structures, namely ovary follicles, B-mode images. Faster R-CNN presented best results, with precision 95.5% recall 94.7% both classes, being able detect all ovaries correctly....
Central serous chorioretinopathy is a retinal disease in which there leak of fluid into the subretinal space resulting mild to moderate loss visual acuity. Sequences images from fluorescein angiography exam are most times used for analyzing these leaks. This work presents diagnostic aid method detect and characterize progression area along exam, order provide second opinion increase focus speed analysis ophthalmologists. The based on comparative approach by image subtraction between late...
<b><i>Introduction:</i></b> Aortoesophageal fistula (AEF) is a rare and potentially fatal cause of upper gastrointestinal bleeding. The classic Chiari’s triad symptoms typical endoscopic findings are not present in all patients, making diagnosis challenging. <b><i>Case Presentation:</i></b> An 86-year-old man was admitted to the emergency room for melena hematemesis with hemodynamic instability. He had previous hospitalization cardioembolic...
El autor describe 29 sitios del Formativo en el valle de Chillón. Los subdivide arquitectura monumental: edificios forma U, pirámide y recinto circular hundido pirámides simples además 17 domésticos. Se presenta una tipología cerámica con propuestas anteriores. La distribución los complejos U se percibe hasta kilómetro 59 pero concentra la parte baja; Huacoy es mayor ellos, comunicado Ancón relacionado 8000 hectáreas tierra cultivable. Chocas probablemente copia menor sistema, mientras que...
Background Hemodialysis (HD) patients with atrial fibrillation (AF) have a particularly high risk of stroke and bleeding, but no high-quality evidence-based recommendations exist to properly manage these patients. Objectives We aim evaluate the ischemic versus hemorrhagic in HD population AF. Methods selected incident that started hemodialysis between 2011 2015. All had AF before HD, or developed during follow-up, were included. Both CHA2DS2 -VASC HAS-BLED scores [...]
