D Developing computer tools with well-designed human computer interactions (HCI) can be difficult, tedious, time-consuming , and expensive. Small improvements in one portion of the design often create disasters in another portion. And staffing necessities often imply that interfaces are designed by expert software engineers who understand neither the users(More)
In a study of home-healthcare practitioners, we found that temporal trends contained in patients' clinical records form one of the most critical pieces of information when selecting and administering appropriate treatment. However, these records are comprised of quantitative and qualitative data, and recorded as a <i>narrative</i>. This format makes the(More)
" OOMS models can be practical if the effort required to product them is commensurate with their limited practical accuracy. " This demonstration details a direct manipulation tool for quickly building OOMS models. Advanced features allow rapid model construction and analysis. The 00MS family of models [4,5] has been used successfully to model various(More)
Digital mammography can potentially improve mammography image and interpretation quality. On-line interpretation from a workstation may improve interpretation logistics and increase availability of comparison images. Interpretation of eight 4k- x 5k-pixel mammograms on two to four 2k- x 2.5k-pixel monitors is problematic because of the time spent in(More)
Stacked displays hold the potential for accurate interpretation of multiple computed tomography (CT) studies on a low-cost workstation. But can such a display scroll as quickly as radiologists can move their eyes to the next image on a film? To address this question, eye-movement duration during CT chest interpretation was recorded using an electronic eye(More)
An ergonomically simple prototype workstation with two 900 x 1,100-pixel monitors capable of displaying eight full-resolution computed tomography (CT) images in 0.2 seconds, was compared with film for interpretation of computed tomographic images of the chest and abdomen. The hardware platform for this workstation cost less than $11,500 in 1993. A(More)
A considerable number of prototype and commercial workstations have been developed during the last 10 years for electronic display of computed tomographic (CT) images during clinical interpretation. These CT workstations have varied widely in the number and size of monitors available for the display of the medical images ranging from a single 1,024 x(More)
