This paper describes a series of experiments to test whether there are significant differences between several different versions of the intelligent medical record-entry system (IMR-E). As the costs of including color graphics decrease, the use of multimedia technologies is becoming an important issue. The development of pen computers provides a whole new range of possibilities for data input. The authors are planning to measure the effects of color, machine speed, and the use of a mouse or a pen computer on input time and user satisfaction when the system is used to input patient data by physicians and medical students.<>

Tighe Belden, W. L. Sembrowich, D. W. Deetz, Frank A. Solomon
A discussion is given on the unique, user-centered design process applied in developing a portable blood gas analysis device. The designers using this process actively and continually drew upon the knowledge and experiences of people who will ultimately use the product. The outcome is a 'tool' that enables people in medical settings to perform a task previously unavailable to them, on-site real-time blood gas analysis. As a tool, the device needed to provide the functions in the most efficient and effective manner. To understand what product interface would be needed to accomplish this, potential end-users were involved throughout the design process. The paper focuses on this user-centered development process that literally brought the device into the hands of clinicians.<>

This paper introduces a new multiresolution predictive scheme for lossless compression of medical images. The proposed scheme consists of three successive steps: namely, multiresolution decomposition, hierarchical interpolation and predictive coding using two-dimensional multiplicative autoregressive models. The performance of the proposed technique is compared with three alternative techniques: namely, difference pyramid (DP), reduced difference pyramid (RDP) and hierarchical interpolation (HINT) method. The experimental results indicate that the proposed scheme achieves significantly higher compression compared to the other techniques considered.<>

Establishing a software engineering process group, SEPG, in a medical device company requires careful planning and organizing to succeed. The author discusses how to proceed after executive management says 'we must be at the best process performance level possible, tell us what to do'. He also includes major problems in establishing a SEPG and how to prevent or correct them. A SEPG's mission is to, 'provide leadership in advancing the state of the practice of software engineering to improve the quality of systems that depend on software'. The main method the SEPG uses is technology transition, 'the process of organizing, executing, and supporting activities that lead to the adoption and institutionalization of new technologies, methods, or approaches such that they become a routine part of doing business'.<>

The authors present a software engineering technique called sensitivity analysis that aims at producing software that is less likely to hide faults. When sensitivity analysis indicates that faults are not likely to hide from testing, they can more comfortably rely on the results of testing. Sensitivity analysis has been automated, and preliminary results from the automated analysis suggest that the technique will have significant advantages for the development, validation, and regulation of medical devices.<>

Faults in a system can result in catastrophic consequences such as death, injury or environmental harm. For example, the Therac 25 incident killed two patients and severely injured a third patient due to a software error. The Therac 25 is a computer-controlled therapeutic radiation machine. Governmental, industrial, and academic researchers are searching for new ways to prevent and detect hazardous faults when developing and certifying safety-critical software systems. To determine the effects of these new techniques, this paper discusses an experiment where developers in the control group followed a traditional methodology while the experimental group followed a modified methodology, which consisted of the control group's methodology along with certain safety-specific methods and guidelines for the following life-cycle phases: specification, design, and verification. The results showed that the experimental group had fewer latent safety-critical faults than the control group.<>

A computer system has been developed for use as an information manager during cardiac surgery. This system interfaces with the patient monitor, heart-lung machine, blood gas machines, computer keyboard, and thermistor probes. The system provides continuous data collection, comprehensive visual display, and storage to a protected ASCII file. Real time data is used to update calculated parameters during surgery. Quality assurance methods include checklists, alarms, graphics capabilities, and software programs which display adherence to protocol. Statistical analysis of objective data may be completed during retrospective studies. Countless upgrades have been applied to the hardware and software, allowing the system to adapt well to the fast pace of medical and technological advances in the operating room.<>

The coronary arteries may be represented and visualized efficiently by a generalized cylinder (GC) model with elliptical cross-sections. By using this model and utilizing quadratic expression of an ellipse, the intensity distribution of an ellipse in any image plane, which is perpendicular to the plane of the arterial cross-section, is computed. A nonlinear parametric model for observed intensity distribution of an arterial cross-section is applied to estimate not only cross-sectional areas but also parameters of the ellipse which are essential in 3-D reconstruction of an arterial segment. This model takes into account background intensity, noise and blurring. Performance of this model has been tested on computer-generated and actual data for various background types and noise values and compared to those of other methods for estimating arterial dimensions. The computed cross-sectional areas from our model for computer-generated as well as actual data demonstrate much less variability than those reported in recent literature. 3-D reconstruction of arterial segments from actual biplane angiograms is presented.<>
