This article summarizes the consensus reached at Summit on Color in Medical Imaging held Food and Drug Administration (FDA) May 8-9, 2013, co-sponsored by FDA ICC (International Consortium). The purpose of meeting was to gather information how color is currently handled medical imaging systems identify areas where there a need for improvement, define objective requirements, facilitate development best practices. Participants were asked concern unmet needs. summary documents topics that...
We have designed and conducted 35 virtual clinical trials (VCTs) of breast lesion detection in digital mammography (DM) tomosynthesis (DBT) using a novel open-source simulation pipeline, OpenVCT. The goal the VCTs is to test in-silico reports that DBT provides substantial improvements detectability masses, while microcalcifications remains comparable DM. For this test, we generated 12 software phantoms (volume 700ml, compressed thickness 6.33cm), varying number simulated tissue compartments...
In this paper, the power consumption of a white-red-green-blue (WRGB) active-matrix organic light-emitting device (OLED) display and resulting temperature distribution across are analyzed as function applied image luminance emitted light. It has been shown previously that directly impacts picture quality an OLED display. Luminance, spectral radiance, measurements performed on 55-in WRGB with resolution 1920 ×1080. A model is presented allows calculating display's for given image. This...
Abstract Modern deep learning models achieve state-of-the-art results for many tasks in computer vision, such as image classification and segmentation. However, its adoption into high-risk applications, e.g. automated medical diagnosis systems, happens at a slow pace. One of the main reasons this is that regular neural networks do not capture uncertainty. To assess uncertainty classification, several techniques have been proposed casting network approaches Bayesian setting. Amongst these...
When designing a new medical display, decisions, e.g., on the choice of panel or back light, must be taken. First decisions are mostly made based physical measurements and not really clinical perceived quality. To prove quality display costly time-consuming psycho-physical/clinical tests performed. solve these issues, virtual image chain (MEVIC) was developed from capture part until visualization for facilitating design. The is composed three main modules: part, specialist. complete...

Up until now, analogue white light dermoscopy standard. Multispectral based on illumination with narrowband sources different wavelengths. Each these wavelengths differently absorbed by chromophores, such as pigment or (de)oxygenated blood. could be a way to enhance visualization vasculature pigment. We illustrate possible...
The purpose of this study is to compare interpretation efficiency radiologists reading radiographs on 6 megapixel (MP) versus 12 MP monitors.
We investigate improvements to our 3D model observer with the goal of better matching human performance as a function viewing distance, effective contrast, maximum luminance, and browsing speed. Two nonlinear methods applying contrast sensitivity (CSF) are proposed, namely Probability Map (PM) Monte Carlo (MC) methods. In PM method, visibility probability for each frequency component image stack, p, is calculated taking into account Barten's spatiotemporal CSF, modulation, psychometric...
Digital pathology systems typically consist of a slide scanner, processing software, visualization and finally workstation with display for the digital images. This paper studies whether images can look different when presenting them on systems, these visual differences result in perceived contrast clinically relevant features. By analyzing set four subspecialties three it was concluded that visualized systems. The importance is elucidated they are located areas contain Based calculation...
Color images are being used more in medical imaging for a broad range of modalities and applications. While the past, color was mostly annotations, today is also widely diagnostic purposes. Surprisingly enough, there no agreed upon standard yet that describes how need to be visualized calibration quality assurance displays performed. This paper proposes display function (CSDF) which an extension DICOM GSDF toward color. CSDF defines calibrated QA can performed obtain perceptually linear...
It is our conjecture that the variability of colors in a pathology image effects interpretation cases, whether it diagnostic accuracy, confidence, or workflow efficiency. In this paper, digital images are analyzed to quantify perceived difference color occurs due display aging, particular change maximum luminance, white point, and gamut. The studied include diagnostically important features, such as conspicuity nuclei. Three different aging models applied images: luminance & chrominance,...

Abstract This paper presents specificities for implementing a psychophysical test room dedicated medical display applications. The main use is to perform subjective measures in normalized environment where results from other psycho‐physical studies can be compared. Standards‐Norms exist and are based on CRT measures, they must adapted LCD.
This paper describes how long-term use impacts the light output of a commercial 55” WRGB AMOLED display with InGaZnO TFT backplane. covers effects which are known by terms “aging”, “image-sticking,” and “burn-in.” The focus is on three different observations: permanent change in as function time, screen burn-in, shift color point. From this work it can be concluded that state-of-the-art OLED displays still suffer from instability under prolonged stress. results suggest explained combination...
The size of medical data has increased significantly over the last few years. This poses severe problems for rapid transmission across hospital network resulting into longer access times images. Also longterm storage becomes more and a problem. In an attempt to overcome increasing often lossless or lossy compression algorithms are being used. paper compares existing JPEG2000 algorithm new emerging JP3D standard volumetric datasets. main benefit is that this truly 3D exploits correlation not...
