A 3D ultrasound scanner: real time filtering and rendering algorithms.

The work described here has been carried out within a collaborative project between DIST and ESAOTE BIOMEDICA aiming to set up a new ultrasonic scanner performing 3D reconstruction. A system is being set up to process and display 3D ultrasonic data in a fast, economical and user friendly way to help the physician during diagnosis. A comparison is presented among several algorithms for digital filtering, data segmentation and rendering for real time, PC based, three-dimensional reconstruction from B-mode ultrasonic biomedical images. Several algorithms for digital filtering have been compared as relates to processing time and to final image quality. Three-dimensional data segmentation techniques and rendering has been carried out with special reference to user friendly features for foreseeable applications and reconstruction speed.

[Long-term electrical stimulation of tachycardias: control by ambulatory electrocardiographic monitoring (author's transl)].

The Authors suggest a new method, elaborated by their own, for long-term antiarrhythmic stimulation. They used ambulatory electrocardiography in order to evaluate the results. It consists of a radio frequency device for synchronization and stimulation, and allows the scanning stimulation of all the cycle of tachycardia, with automatic search for the zone of interruption. The stimulatory is carried by the patient, who must set it in motion at the onset of the tachycardia. Preliminary results show the efficacy of the method; Holter monitoring seems to be the best guide to the development of a satisfactory implantable automatic tachycardia-terminating pacemaker.
