Patent ID: 7789830

Claim:
A thrombus detecting apparatus comprising: a transducer, which is attached to a monitor portion of a subject and transmits and receives ultrasonic waves, a transmitter and receiver unit, which transmits and applies driving pulses to the transducer and receives echo signals output from the transducer, and a first detector which processes output signals of the transmitter and receiver unit, and detects a thrombus passing through a blood vessel, and a light source, which generates living body inspection light, a probe, which is attached to a monitor portion of the subject and irradiates the living body inspection light from the light source to the subject, a light receiving unit, which receives living body inspection light irradiated from the probe and passed through the subject and outputs electrical signals depending on the intensity of the received living body inspection light, and a second detector which processes the output signals of the light receiving unit and detects a thrombus passing through a blood vessel, characterized in further comprising a thrombus comprising a thrombus counting unit, which counts both the number of thrombus detected by the first detector and the number of thrombus detected by the second detector.
