Abstract
A medical system incorporates a perforated flexible web conformable to a patient, at least one electroacoustic transducer attached to the web, an a-c current source being operatively connected to the transducer for energizing the transducer with an electrical signal of a pre-established ultrasonic frequency to produce a first pressure wave. At least one acoustoelectric transducer is attached to the web, while an analyzing component is operatively connected to the acoustoelectric transducer for determining three-dimensional shapes of internal organs of the patient by analyzing signals generated by the acoustoelectric transducer in response to second pressure waves produced at internal organs of the patient in response to the first pressure wave. An image of internal organic structures derived through the ultrasonic signal analysis is displayed on a video monitor for enabling direct observation of invasive diagnostic and therapeutic operations. Instruments are inserted into the patient through apertures in the flexible ultrasonic sensor web.
