A method has been developed to detect and analyse microcalcifications in digitized mammographic images. The algorithms presented in this work combine an image preprocessing to denoise the digital image and image treatment techniques to localize and characterize the features of the microcalcifications. Two image denoising methods have been applied to the mammographies, the first one is an adapti...

BACKGROUND Delay in diagnosis of cancer may worsen prognosis. The aim of this study is to explore patient-, general practitioner (GP)- and system-related delay in the interval from first cancer symptom to diagnosis and treatment, and to analyse the extent to which delays differ by cancer type. METHODS Population-based cohort study conducted in 2004-05 in the County of Aarhus, Denmark (640,000...

OBJECTIVE To describe the clinical characteristics of infants with acute viral bronchiolitis (AVB) and to assess the influence of oxygen desaturation time (DT) as a prognostic test to estimate the evolution of such patients. METHODS We performed a cohort study with 111 hospitalized patients diagnosed with AVB receiving oxygen therapy through nasal prong. The outcomes were: length of admission...

Computed radiography (CR) is a digital radiographic technique, which uses very similar equipment to conventional radiography except that in place of a film to create the latent image, an imaging plate (IP) made of a photostimulable phosphor is used [1]. CR systems are commonly used in medical applications since they have proven reliability over more than two decades. Conversely, the NDT communi...

AIM Developing a method of maximizing maternal expulsive effort should be of great value in reducing the number of cesarean sections or instrumental deliveries. Various investigations have shown that use of a dental support device (DSD) increases the isometric strength of different muscle groups. The aim of our study was to investigate the role of a DSD in second stage of pushing. METHODS Nul...

A adaptive Switching median filter for salt and pepper noise removal based on genetic algorithm is presented. Proposed filter consist of two stages, a noise detector stage and a noise filtering stage. Particle swarm optimization seems to be effective for single objective problem. Noise Dictation stage works on it. In contrast to the standard median filter, the proposed algorithm generates the n...

This study examined the error probability performance of polar codes across Fox’s $H$ -fading (FHF) channels while taking into account in-phase and quadrature-phase imbalance (IQI), as well residual hardware impairments (RHI). fading ...
