Ultrasonic Two‐Dimensional Visualization for Medical Diagnosis

Visualization of Rough Set Decision Rules for Medical Diagnosis Systems

An ability of Pawlak’s Rough Sets Theory to handle imprecision and uncertainty without any need of preliminary or additional information about analyzed data makes this theory very interesting for analyzing medical data. Using Rough Sets Theory knowledge extracted from raw data may be stored in form of decision rules. But increasing number and complexity of decision rules make their analysis and...

Interactive Visualization for Information Analysis in Medical Diagnosis

This paper investigates to what extend the findings and solutions of information analysis in intelligence analysis can be applied and transferred into the medical diagnosis domains. Interactive visualization is proposed to address some of the problems faced by both domain. Its design issues related to selected common problems are then discussed in details. Finally, a visual sense making system ...

Investigation of ultrasonic waveguides for medical therapy

Theoretically it was determined that changing longitudinal rigidity of waveguide the longitudinal vibrations amplitudes are increasing. The cross-section of waveguide is decreasing from the generating point towards its free end. Experimental results show that the free end of the waveguide is influenced by longitudinal vibrations only, which could be used for blood vessels cleaning.

Biplane Phased Array for Ultrasonic Medical Imaging

We report a transducer structure tha t combines two orthogonal phased arrays which enable the real-time scanning of two orthogonal sectors. This biplane phased array is formed by partially dicing the opposite faces of a composite piezoelectric plate in orthogonal directions. Individual elements of the orthogonal arrays show broad radiation patterns close to the theoretical expectations for isol...
