These reports conform to the DICOM standard by using the 'structured reporting' supplement of DICOM. The user interface of the editor is implemented in Java. A DICOM toolkit is used to implement the structure of the reports. The toolkit is implemented in the programming languages C and C++ and can be compiled on the operating systems Linux, Windows NT/9x and Solaris. The programming languages used for the implementation of the user interface and for the construction of DICOM-conforming reports are connected via the Java Native Interface (JNI). The possibility to record spoken language or noises, to visualize DICOM images and to edit natural text is also provided.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

The traditional practical cone-beam reconstruction method, the Feldkamp algorithm, was previously (L.A. Feldkamp et al., 1984) generalized to the case of spiral/helical scanning loci with equispatial cone-beam projection data. In this paper, we formulated the generalized Feldkamp algorithm in the case of equiangular cone-beam projection data. Because medical multi-slice/cone-beam CT scanners typically use equiangular projection data, our new formula may be useful in the area of medical X-ray imaging.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

This paper presents some pilot-study results from the application of CBIC to mammography. Unlike traditional compression approaches, CBIC first analyzes the content of the data before the compression takes place. In this approach, prior to compression, the data is pre-processed and is segmented into two non-overlapping regions: (1) focus-of-attention regions (FARs) that contain the \"important\" segments of the data, and (2) background regions. Subsequently, the former regions are compressed using a lossless compression technique (maintaining fidelity), while the latter regions are compressed with the aid of a lossy technique (attaining large reductions in data). The intended result is an optimal balance between data reduction and data fidelity. In this case, compression ratios 5-6 times greater than that of lossless compression alone can be reached while preserving the important information.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

Any system developed to access clinical information must do so efficiently while dozens of examinations await interpretation. radStation is a clinical display/report dictation system that has been designed not only to provide an effective interface to unrelated legacy databases but also to effectively integrate into the existing dictation workflow of radiologists. The three-tiered system architecture provides for efficient access to existing legacy databases and allows for future expansion with additional middle-tier (business rules) servers that are able to maintain robust interfaces to legacy databases (the database tier). However, the system architecture is of little concern to a practicing radiologist when experiencing robust system response. The system requires almost no training to master and is well-accepted by a very busy oncological radiology specialty practice.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

Uncertainty in assessing penetrating injuries arises from two different sources: the actual extent of damage associated with a particular injury mechanism may not be easily discernable, and there may be incomplete information about patient findings (signs, symptoms and test results) which provide clues about the extent of the injury. Bayesian networks are used in TraumaSCAN for diagnostic reasoning because they provide a mathematically sound means of making probabilistic inferences about the injury in the face of uncertainty. We also present a comparison of TraumaSCAN's results in assessing 26 actual gunshot wound cases with those of TraumAID, a validated rule-based expert system for the diagnosis and treatment of penetrating trauma.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

Acute, severe illness may require care in an intensive care unit (ICU), with many aspects of care managed concurrently. Variation of aspects of care among patients, clinicians, ICUs and institutions is well-known, and is due to a lack of standardization in clinical decision making and the inability to implement detailed, patient-responsive protocols. Automation of protocols for specific aspects of care using computing technology and medical informatics/knowledge engineering principles offers a consistent, systematic way to implement a protocol by prompting bedside clinicians in a timely manner monitoring a patient's responses to therapeutic interventions, and monitoring the decision logic used. This paper describes a new generic system for the design and implementation of computerized protocols.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

The hospital is experiencing diminishing profitability and market share. Hospital management cannot analyze the problems and make effective decisions because of their inability to combine data from independent business functions. As a condition of her contract renewal and continued operation of the hospital, the Board of Directors has given the (CEO) one year to reverse these trends. The CEO has decided to focus, among other areas, on marketing. She needs a combination of data from the patient, pharmacy, radiology, and pathology databases. The Chief Information Officer (CIO) has 90 days to ascertain the information needed by the CEO's Executive Staff, and to build a data warehouse solution.

In order to detect and limit the enhancements to the region defined by the brain mask, a combination of thresholding and mathematical morphological operations was implemented. A 3D connected component labeling algorithm is used for producing both the brain mask and labeling the enhanced lesions. False positives that arise from the enhancing vasculature and structures that do not exhibit a blood-brain barrier (BBB) were automatically detected and eliminated by spatially registering the Tl-weighted and the dual-echo affirmative images. Lesion enhancements were delineated using fuzzy connectedness. This technique is evaluated on MS patients with excellent results.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

One strategy involves maintaining a global cooling schedule/visiting schedule which is turned on or off (or forcing extremal temperature values) at a site depending on the interiteration behaviour of the classifier. This (0,1)-valued behaviour of the cooling schedule is parameterized relative to the site. We give a preliminary discussion of a method of assigning such parameters based on a multigrid decomposition of the image.
