Artificial neural networks were used to classify blood cells. Compared with existing methods, neural networks are more accurate, efficient, adaptable and information-rich. The implementation of the system in a PC/Windows NT environment using image processing technology and database management allows for a variety of features to be extracted and a variety of training algorithms to be used. In this preliminary study, blood cell images are segmented to individual cells. Features for individual cells, including size, color content and shape related moments, are extracted and used as inputs to a multilayer neural network. Backpropagation and ALOPEX training algorithms were used to train the neural network. After less than 2000 training iterations using 95 training sets, the system recognized three kinds of blood cell in a correctness percentage of 100%. This module provides a platform to build a more sophisticated computational intelligent system for cell classification for clinical use.

In parallel with rapid advances in computer technology, biomedical functional imaging is impacting to an ever increasing extent on healthcare. Functional imaging allows us to see dynamic processes quantitatively in the living human body. However, as we need to deal with 4 dimensional time varying images, space requirements and computational complexity are extremely high. This makes information management and communication difficult. Using the minimum amount of data to represent the required information, developing fast algorithms to process the data, organizing the data in such a way to facilitate information management, and extracting the maximum amount of useful information from the recorded data, have become important research tasks in biomedical information technology. For the last 10 years, the Biomedical and Multimedia Information Technology (EMIT) Group has conducted systematic studies on these topics. Some of the results relating to functional imaging data acquisition, compression, storage, management, processing, modeling and simulation, are reported.

The paper discusses the design of a minimum power 2.45 GHz pulse receiver and companion transmitter for use in a semi active, duplex RF transponder. A 50 /spl Omega/ microstrip stub matched zero bias diode detector forms the heart of the body-worn receiver, achieving a tangential sensitivity of -56 dBm. Three-pole bandpass filtering provides rejection of out of band signals, typically 28 dB in the 900 MHz cellular band. A 3.6 V portable on-off-keyed transmitter with suitable output power to communicate with the transponder provided a full mobile transmitter for system tests.

Despite the increasing use of the DICOM standard, available today both in the research environment and among commercial products, its extensive application in a wide hospital environment still presents several problems concerning the management of the devices and the security of the system. The implementation of the Data and Picture Archiving and Communication System (DPACS) at the Cattinara Hospital of Trieste, showed the need for a centrally-managed service for organizing a large number of devices and for handling a valid security policy. The aim of this study is the development of a DICOM extension, in terms of a new DICOM Service Class, to allow its secure and efficient implementation in a wide environment. The proposed Service Class, called DICOM Domain Management, has been initially developed as a private extension of the standard and is being tested and revised.

Recent adva.nces in image and signal processing have created a new challenging environment for biomedical engineers. Methods that were developed for different fields are now finding a fertile ground in biomedicine, especially in the analysis of bio-signals and in the understanding of images. More and more, these methods are used in the operating room, helping surgeons, and in the physician's office as aids for diagnostic purposes. We have useld advanced signal processing and innovative image processing methods that are used along with computational intelligence for diagnostic purposes and as visualization aids inside and outside the operating room. The software is written in C" in a windows environment and can be used on any PC. We will demonstrate some applications on a 233 M H z laptop, equipped with a 5 Gigabyte hard disk and 64 MB of memory.

The field of healthcare information management has a bright future. Most health care organizations are investing heavily in this area and additional staffing will be required. Many obstacles remain, however. This is especially evident in the development of the electronic medical record. Some of these obstacles can be overcome by technology. For example, solutions are needed to facilitate data entry, to store and stage vast amounts of data, to facilitate the review of this data, and to provide online decision support. In order to succeed, we must make efficient use of our engineering and management talent.

We have recently developed objective methods for characterization of shapes of microcalcifications and tumors in mammograms, and measures of acutance for characterization of the radiographic definition (or edge sharpness) of tumors. The measures and factors quantify subjective descriptors used by radiologists in diagnosis and decision making. While computer extracted features permit computerized pattern recognition and decision making, they may not be readily usable by the radiologist in a computer aided diagnosis system. The objective of the work presented is to improve the diagnostic efficiency of mammography by the use of visualization tools. We propose an iconographic (or iconic) display system based upon graphical icons whose characteristics are related to the computer extracted shape factors and other features of mammographic entities. The icons are presented to the radiologist in the form of an image; the locations and visual characteristics of the icons are associated with corresponding diagnostic entities such as microcalcifications and tumors. The procedure is expected to assist radiologists in interpreting the features in an objective manner, and hence improve diagnostic efficiency.

This group/ panel discussion will focus on three areas: 1.Disease Management and Prevention, 2.IT Impact on Health Services Research, and 3.Applications in Biomedical Research. The intention of this presentation is to tie fiom an information technology perspective, a vision which will allow for improvements in outcomes, quality of life while decreasing costs. The emphasis will be in disease prevention, rather than diagnosis / treatment as currently practiced in most countries, and broad consumer as well as provider education. Information technology components are many. Besides the common topics of: vocabulary, coding, and standards on one hand and the information infrastructure, i.e. Internet, Internet2, Next Generation Internet, on the other, the areas of particular interest are: the integration of very large knowledge repositories, multimedia, virtual environments, data base and knowledge processing technology as well as intelligent sensors and U 0 devices. The major threads will include: knowledge processing and cognition, knowledge repositories, connectivity and interaction, information agents and environments. Some of the applied topics include: summarization (fusion encoding; visualization), queries, intelligent transactions, distributed intelligence and meta agents. The application areas are: home care, the elderly, chronic disease prevention and genetics.
