Title:
DOUBLE SCANNING ULTRASONIC SCANNING APPARATUS
Document Type and Number:
Japanese Patent JPS57117841
Kind Code:
A
Abstract:
An ultrasonic scanner for use in medical diagnosis which produces two different types of scans. The scanner includes a housing carrying one or more ultrasonic transducers which traverse an arcuate path. A first reflector is positioned within the arcuate path to intercept ultrasonic waves and converge them at a point beneath the scanner in order to produce a skin centered sector scan, which is useful for viewing through small acoustic windows such as intercostal regions. A pair of reflectors, one of which is positioned horizontally with respect to the first reflector and the transducers, are utilized to form a wide aperture sector scan which diverges upon exiting the scanner housing. The wide aperture scan is useful for scanning spaces such as the abdomen which include relatively few obstructions.
