Ultrasonic Tomographic Imaging of the Brain with an Electronic Sector Scanning System

Technology in health care: Medical “early warning systems” may lighten the load on patient treatment systems

“…Another ultrasonic imaging system, called t h e Electroscan, has been developed for imaging of the brain. 3 The system uses a probe consisting of an array of several elements, spaced one-half wave length apart, that are excited successively for vary ing but mutually equal time intervals. Pulses can be transmitted in several directions within a sector of 90 degrees.…”

New Ultrasound and Related Imaging Techniques

“…For example, the proliferation of array sector scanners and array parallel scanners in clinical settings depends in part upon wide clinical acceptance of their improved images and ease of operation. It seems likely that this acceptance would have been more rapid if earlier workers had applied these techniques to the heart, where the real time imaging capabilities of arrays are maximally used, rather than to the head [1]. The eventual application of real time sector scanning [2] and parallel scanning [3] to the heart coupled with the more widely accepted use of the cross sectional or B-scan display mode rather than the older A-scan mode has also contributed to the increased popularity of ultrasound imaging.…”
