MEMS / PHOTOACOUSTIC/ULTRASOUND HANDHELD PEN-TYPE PROBE USING MEMS SCANNER AND PHOTOACOUSTIC IMAGE ACQUISITION SYSTEM AND METHOD USING THE SAME

摘要

[0001] The present invention relates to a photoacoustic / ultrasonic manipulation pen type probe using a MEMS scanner, and a photoacoustic image acquisition system and method using the same. More particularly, the present invention relates to an ultrasonic transducer capable of receiving and transmitting photoacoustic / ultrasound signals. A light transmission unit arranged to be vertically positioned with respect to the ultrasonic transducer and transmitting a laser supplied from an external light source; A beam coupling unit arranged to be in contact with the ultrasonic transducer and the light transmitting unit and passing the laser transmitted through the light transmitting unit and reflecting the photoacoustic signal generated from the object in the direction of the ultrasonic transducer; And a scanner which is disposed to be positioned between the beam combiner and the object and reflects the laser beam passed through the beam combiner toward the object and reflects the photoacoustic signal generated from the object in the direction of the beam combiner As a characteristic feature thereof.According to the photoacoustic / ultrasonic grip type pen-type probe using the MEMS scanner proposed in the present invention, and the photoacoustic image acquisition system and method using the same, the MEMS scanner is used. In order to integrate all the systems into the integrated probe type, The scanner may also be configured in a diagonal fashion to achieve linear alignment of the scanner by integrating the light delivery portion, the ultrasonic transmitter, and the mechanical MEMS scanner all in one small tube, Therefore, it is possible to reduce the size of the device while realizing the quick shooting function, and it is possible to diagnose the abnormality of the internal organs in the real time and to perform the tumor boundary check, thereby reducing unnecessary bleeding and tissue removal range, To provide immediate medical judgment to medical personnel, and to provide more sophisticated This may be drinking.;
