    This paper describes a knowledge-based system for the diagnosis of acute abdominal pain, in which scores and rule sets are integrated. The system is linked to a documentation program via a medical data dictionary and allows an on-line application of knowledge modules to clinical data. Different rule sets were generated by automatic rule generation (C4.5) from a prospective database. The rule sets ... View full abstract»

    Monitoring follicles is especially important in human reproduction. Today, the monitoring of follicles is done non-automatic, with human interaction. This work can be very demanding and inaccurate, and in most cases means only an additional burden for the experts. In this paper, new algorithm for automated computer-assisted defection of follicles in ultrasound images of ovary is proposed. It has t... View full abstract»

    Publication Year: 1997, Page(s):34 - 39
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (383 KB)

    We developed a cellular automaton that is able to extract the information about the position of follicles in the ultrasonic image. Follicles are small protective sacs containing ova in the cortex of women's ovaries, and their ultrasound monitoring is very important in diagnosing and treatment of infertility. The original ultrasonic images were reduced in size and number of colours and then used as... View full abstract»

  • Interfacing anesthesiology operating room data with statistics software packages

    Publication Year: 1997, Page(s):42 - 47
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (250 KB)

    During an operation, data is collected on operative events including start and stop times and on continuous data distributions such as heart rate, and blood pressure. This means that records from different operations are of different lengths since the amount of data collected depends on the length of the operation. Padding all records to the same length is a waste of disk space and processing time... View full abstract»

    The Electronic Portal Imaging Device (EPID) uses a high-energy treatment beam to project the body interior of a patient on to a fluorescent screen that is scanned by a camera. Because of the imaging physics, the unprocessed images are very poor in quality. This paper presents an approach that combines an associative restoration algorithm with a fuzzy image enhancement technique. By fusing the elec... View full abstract»

    This paper presents a full reconstruction process of magnetic resonance images. The first step is to bring the acquired data from the frequency domain, using a fast Fourier transform algorithm. A tomographic image interpolation is then used to transform a sequence of tomographic slices in an isotropic volume data set, a process also called 3D reconstruction. This work describes a method the interp... View full abstract»
