Abstract: A tissue-sensing adaptive radar method of detecting tumours in breast tissue uses microwave backscattering to detect tumours which have different electrical properties than healthy breast tissue. The method includes steps for reducing skin reflections and for constructing a three-dimensional image using synthetic focusing which shows the presence or absence of microwave reflecting tissues.

Abstract: An ultrasonic transmission/reception apparatus which can image both a minute tissue around a bone part in an object and a minute tissue inside the bone, at a high resolution. The apparatus includes a system control unit which controls the synthesizers so that a first ultrasonic wave may be transmitted from one of the transmission elements while its frequency is being swept, and that a second ultrasonic wave may be transmitted from the other transmission element while its frequency is being swept with a predetermined difference frequency held relative to the frequency of the first ultrasonic wave, a signal processing unit which subjects the detection signal of the ultrasonic echo to predetermined signal processing, a signal processing unit which subjects the detection signal of the vibro-acoustic sound to predetermined signal processing, and a display-image arithmetic unit which generates B-mode image data based on the detection signals subjected to the signal processing.
