PACSPulse, an open-source tool, was developed to identify and analyze the performance bottlenecks of picture archiving and communication systems (PACS). PACSPulse provides a graphical Web interface for straightforward analysis of PACS performance on the basis of data acquired by tracking usage by network, server, workstation, type of traffic, and time of(More)
BACKGROUND Effective learning can occur at the point of care, when opportunities arise to acquire information and apply it to a clinical problem. To assess interest in point-of-care learning, we conducted a survey to explore radiologists' attitudes and preferences regarding the use of just-in-time learning (JITL) in radiology. MATERIALS AND METHODS(More)
Radiology departments are besieged with a multitude of information systems, each needing significant technical support. Information systems include the dictation system, the radiology information system (RIS), the picture archiving and communication systems (PACS), and every workstation and acquisition modality along with any dedicated system such as a(More)
Cardiac output is the volume of blood ejected by the heart per unit time. It is a useful measurement in that it can be used to evaluate overall cardiac status in both critically ill patients and patients with suspected cardiovascular disease. An ideal cardiac output measurement system would have automated continuous output capability, be minimally invasive,(More)
There is growing interest in bringing medical educational materials to the point of care. We sought to develop a system for just-in-time learning in radiology. A database of 34 learning modules was derived from previously published journal articles. Learning objectives were specified for each module, and multiple-choice test items were created. A web-based(More)
Cardiac output is frequently measured to assess patient hemodynamic status in the operating room and intensive care unit. Current research for measuring cardiac output includes continuous sinusoidal heating and synchronous detection of thermal signals. This technique is limited by maximum heating element temperatures and background thermal noise. A(More)
