Usability Practice in Medical Imaging Application Development

2009

Historically, development of medical imaging applications has focused on solving technical issues for small numbers of expert users. However, their use is now more mainstream and users are no longer willing to tolerate poor performance and usability. In this study we illustrate the application of user centred design methods in a medical imaging applications development company by using a usability comparative study of different regions of interest (ROI) tools. A use case analysis was used to judge usability efficiency and effectiveness of different ROI tools; and a user observation was also carried out which measured the accuracy achieved by these tools. We have found that useful results can be obtained by using these methods. We also generated some concrete suggestions that could be incorporated into future product development.

A Novel Graphical-Oriented Framework for Capturing Data within Clinical Information Systems

International Journal of Healthcare Information Systems and Informatics, 2013

One of the main challenges in the development and implementation of computerized health care systems is the physicians and nurses’ resistance, stemming in particular from the use of text based environments for the capture of their medical examination data. The purpose of the present study was to propose the basis for a graphical oriented framework which can be used to capture data for a medical examination therefore easing the data-entry using the keyboard. Following analysis of a classical general medical examination, an XML schema was designed to describe physical examinations. Based on the physical examination XML schema, XML data structures are transformed to HTML using XML transformation style sheets to create dynamic graphical user interface (GUI) widgets; user interactions with the widgets leads to the generation of sentences. The key advantages of the proposed system are: a) a reduction in the keyboard usage, b) the ability to codify the generation sentence accurately and c)...

High usability Graphic User Interfaces (GUIs) for the continuous assessment of chronic diseases

This paper presents technical solutions for achieving high usability in user interfaces for the continuous assessment of chronic diseases. Our overall goal is to design usable systems, which support specific users in their specific context to reach their particular goals effectively, efficiently and with satisfaction. Usability is a quality attribute that assesses how easy user interfaces are to use, defining five quality components: learnability, efficiency, memorability, errors and satisfaction. Our approach is to keep interfaces as simple and clear as possible. We have worked within the MyHeart project, which deals with patients with chronic cardiovascular diseases. Patients are equipped with an intelligent biomedical garment capable of acquiring, processing and evaluating physiological data such as ECVs. The results are sent via a wireless personal area network to a mobile phone or PDA and from there to a server farm. The mobile device will include an avatar that will perform th...

Usability Engineering of a Radiological Workstation for Mobile Devices: An Experience Report

Anais do Simpósio Brasileiro de Computação Aplicada à Saúde (SBCAS), 2020

Medical imaging is commonly used to diagnose many emergent conditions as well as plan treatments. Digital images can be visualized on almost any computing device that has a screen. These days most devices used to visualize digital images are still desktops. Despite that, the world that surrounds us is evolving to a more mobile environment, therefore, mobile devices are increasingly being incorporated onto Picture Archiving and Communication Systems (PACS). In this paper we describe the usability engineering of a new medical image viewer for iPads as a Teleradiology tool for evaluating CTs, X-Rays, Ultrasounds, etc. First we gathered requirements, after we created a series of prototypes and finally the development of the actual application. The experience resulted in insights into how to develop an appropriate viewer for the specific target end user group. Our results suggest that emergency conditions commonly encountered on CT and MRI can be diagnosed using tablet computers with goo...

A review of existing and potential computer user interfaces for modern radiology

Insights into imaging, 2018

The digitalization of modern imaging has led radiologists to become very familiar with computers and their user interfaces (UI). New options for display and command offer expanded possibilities, but the mouse and keyboard remain the most commonly utilized, for usability reasons. In this work, we review and discuss different UI and their possible application in radiology. We consider two-dimensional and three-dimensional imaging displays in the context of interventional radiology, and discuss interest in touchscreens, kinetic sensors, eye detection, and augmented or virtual reality. We show that UI design specifically for radiologists is key for future use and adoption of such new interfaces. Next-generation UI must fulfil professional needs, while considering contextual constraints. • The mouse and keyboard remain the most utilized user interfaces for radiologists. • Touchscreen, holographic, kinetic sensors and eye tracking offer new possibilities for interaction. • 3D and 2D imagi...
