Title: Albert S. Waxman: Innovator in Ultrasound Technology
Introduction
Albert S. Waxman is a notable inventor based in Los Gatos, California. He has made significant contributions to the field of ultrasound technology, holding a total of 3 patents. His work has advanced the capabilities of medical imaging, particularly in cardiac examinations.
Latest Patents
One of his latest patents is a multi-mode ultrasound scanner. This innovative device features a scanner head employing split semicircular transducers. In certain modes, such as simultaneous B-scan and M-scan, each transducer operates independently. For continuous Doppler mode, the transducers move in unison. This relatively small, hand-held scanner head is particularly useful for cardiac examinations. Another significant patent is for an ultrasonic imaging apparatus that utilizes a coupling fluid mixture of propylene. This invention includes a data acquisition head for an ultrasonic imaging system that employs multiple transducers. The transducers are rotated in a liquid-filled chamber at a constant rate, each about an axis perpendicular to its transmission axis. They are sequentially activated as their transmission axes cross a semi-rigid membrane in contact with the body. The acoustic impedance of the liquid and membrane, along with the thickness of the membrane, are matched to enhance transmission. In one embodiment, the membrane is one-half or a full wavelength thick and comprises low-density polyethylene, while the liquid has an acoustic impedance approximately equal to that of the polyethylene.
