This paper outlines the characteristics and design requirements of an image workflow management system (IWFMS) in a large-scale hospital environment. In this paper, we present a four-tiered enterprise architecture of an IWFMS for supporting the streamlining, automating and monitoring of the flow of the medical images in a large-scale consortium of hospitals known as the Clarian Health System in Indianapolis, IN, USA. The first tier presents the graphical user interface (GUI) that enables users to view and interact with the workflow engine. The second tier implements the business model that depends on the work requirements within the different units of the hospital system. The third tier implements the business logic and automates tasks that support image flows. The fourth tier is the back-end database that is used to store and retrieve workflow data. The components in each tier have been designed and implemented as a set of CORBA objects that provide seamless integration of the image flows in the Clarian Health System.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

These two fields are cytogenetics and digital imaging. Cytogenetics is the biological study of the genetic makeup of cells. It is used extensively in genetic diagnosis and cancer research. Digital imaging is the computer engineering technique of processing pictures in a computer. It is widely used in medicine, military, industrial, entertainment, and aerospace applications. Digital imaging has contributed to cytogenetics instrumentation that reduces the workload in clinical labs and produces quantitative data for both research and diagnosis. At the same time, cytogenetics has furnished the problems that have prompted the development of a broad range of techniques that prove useful in fields far beyond genetics. This talk traces the parallel and interacting histories of these two fields. Breakthroughs in one have led to advances in the other throughout their development. This illustrates how necessity in one field is the mother of invention in another, and how both have benefited from their interaction.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

The main reason is that, in many cases, it is necessary to have direct information about the size, shape and exact location of the aneurysm. To provide a medical specialist with such information, a virtual aneurysm system has been created. Problems with its realization and efficiency are discussed in this paper. A novel approach to the simulation and visualization of biomedical systems is suggested, so as to achieve higher efficiency. This approach is called \"branching simulation\".","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

Once the kinematic structure is defined, control points for interactive definition of tendon and muscle parameters may also be defined and adjusted, leading the way to interactive musculoskeletal modeling and simulation. All kinematic transformation nodes are built as linkages within an OpenGL hierarchical structure. The structure for the independent adjustment of each axis of motion required tracking the inverse of all transformations applied to the axis during visualization and adjustment. The inverse is applied to all structures in the hierarchy below the axis of interest so that only the axis is affected during 3D adjustment. The result is a kinematic structure definition program with which the user interactively builds the kinematic model. The program has the capacity for unlimited rotational DOFs. The system allows for the visual adjustment and verification of the placement of axes. This interactive task is carried out through control of the observer viewpoint and the position and orientation of the view and of each axis. These dynamic commands are carried out simultaneously with rotational control of distal joint segments about their defined axes. With such flexibility, the user is able to rapidly iterate upon appropriate axis placement based on a 3D visual verification of joint congruence throughout the joint range of motion.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

A surgical intervention to diminish internal rotation during gait in the cerebral palsy population has included soft tissue procedures and rotation osteotomies. One common procedure is varus rotation osteotomy (VRO). We report on the results for 37 people with cerebral palsy who were at least 3 years old, cooperative and able to follow directions. The average age at the pre-operative test stage was 8.7+3.3 years. There were 14 males and 23 females. 35 were diplegics and two were quadriplegics. Each was tested pre-operatively, at six months post-operative and at 12 months post-operative. The mean difference curve, along with the 95% confidence interval about the difference, was calculated using a bootstrap technique. The depiction of the bootstrapped curves is compared with the use of the maximum value for comparisons.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

The center of the carotid artery is tracked using the Star algorithm. The stability of the Star algorithm has been improved by using a temporal Kalman filter. A spatial Kalman filter is used to estimate the carotid artery boundary. Since the method does not employ any numerical optimization, convergence is very fast. The stability and accuracy of the method is demonstrated by tracking the carotid artery over a 30 second sequence of ultrasound images taken during a carotid artery examination. An application of the tracking method to ultrasound image servoing is also presented.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

Physicians now can provide better services at lower costs through the efficient management of medical information. In recognition the importance of the interoperability of medical information, both government agencies and the private sector have made considerable investment in various medical standards, such as DICOM, HL7 and various electronic patient record systems. Among many of the standards activities, one missing element is a universal software model that would enable physicians to integrate and customize various medical information products into a complete suite for their particular needs. A software tool built on the basis of such a software model should be provably reliable, verifiable and field-configurable. It should allow instrument vendors to embed their hardware and software solutions into the tool without compromising their proprietary designs. This tool should be able to communicate and command different instruments in a consistent manner, so that new applications can be built upon well-known and well-accepted software layers. To demonstrate the effectiveness of this solution approach, we developed a portable medical information management prototype, the Portable Remote Diagnostic Information and Telemedicine System (PoRDITS).","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.
