Description
Technical field
The present invention relates to a kind of ultrasonic inspection devices, particularly a kind of Portable medical supersonic equipment supersonic detection device.
Background technology
Ultrasonic application in medical treatment is just becoming more and more important.Applying from it, medical ultrasound substantially can be divided into diagnostic ultrasound and treat ultrasonic two application directions by us.
The application of diagnostic ultrasound is the most ripe, super (A-mode) from A, B ultrasonic (B-modc), C super (C-mode) is super (M-mode) to M, and the B ultrasonic of employing higher hamonic wave imaging, of a great variety, technology is the most ripe.
Recent years, treating ultrasonic has had breakthrough in terms of focus ultrasonic knife, ultrasonic rubble successively, 7 great development are obtained in terms of clinical practice, particularly (i.e. High Intensity Focused Ultrasound HighIntensityFocalUltrasound (HIM) has the development in the leading world to focus ultrasonic knife in China, has the biggest application prospect.But, compared with the extensively application of medical ultrasound, the restraining factors of its development show the most significantly..
The application of medical ultrasound, is a kind of accurate application to ultrasonic sound field, in theory, and description that this application first has to have complete and accurate to medical ultrasound sound field and measuring.But, due to particularity and the complexity of human tissue structure of ultrasonic measurement, result in accurately description and the measurement of ultrasonic sound field in human body the most extremely difficult.Therefore, the application to medical ultrasound is to have walked a road first applied.I.e. under the conditions of having had sound field substantially to describe, first carry out applications of ultrasound, obtain zoopery and the medical experience of clinical practice, as later guidance.The sound field faced the difficulty accurately describes and measures, and solves after giving over to again.
In this case, the medical application of medical ultrasound is just taken an early lead, and achieves the achievement making common people gaze at, and its diagnosis and therapeutic effect obtain the extensive approval of medical circle.But, in the case of being sized medical ultrasound effect we oneself, its acoustic measurement is still in the stage immature, incomplete, oneself can not be compared with the successful Application of medical ultrasound through far away, it can be said that in the application aspect of medical ultrasound, the contribution that physician is done is greater than acoustician.As former sound field space measurement uses screw drive space to scan mode, its precision and the scope of measurement are limited, far do not reach the requirement of IEC standard.
But, in electronic technology and today of computer technology fast development, if acoustic measurement can combine with up-to-date technology, it is believed that be to be entirely possible to break through original measurement limit to, to reach tentatively to meet the needs of clinical medicine application.
It is known that, medical supersonic equipment is when disease diagnosis and therapy, in order to ensure the effect of Clinics and Practices, need ultrasonic image clear, but, image is the most clear, and the output acoustic power of diagnostic ultrasound equipment will be the biggest, excessive ultrasonic output will produce biology change to tissue, in some instances it may even be possible to causes the deformity etc. of fetus.Therefore, safety should be ensured, reach the clear main body having become conflict with biological effect of image again.For the use ultrasonic device that ensures safety, in industry, propose the problem that medical supersonic equipment is used ultrasonic secure threshold.For that purpose it is necessary to the sound parameter of medical supersonic equipment is evaluated, it is ensured that the safety in clinical practice.
Hydrophone, also known as underwater microphone, is transducer underwater signal being converted to the signal of telecommunication.It is all mudulation effects utilizing properties of materials and it and surrounding interaction to produce, the instrument of the signal such as pressure, sound in detection liquid.At civil area, hydrophone can carry out oil exploration, marine organisms monitoring, seabed investigation etc. by detection underwater sound signal.In military field, hydrophone as sonar system foremost, carries the effect of detection unfriendly target signal.Be used for by hydrophone medically, then can be used to detect in medical supersonic equipment is ultrasonic, to measure these ultrasound value whether within the range of receiving of safety.
No. 200610088285.4 Chinese invention patents of Application No. disclosed in December in 2007 27 days, entitled " medical ultrasonic detection method and the system " of its innovation and creation.Wherein, medical ultrasound detection device includes being provided with the device that hydrophone measures in tank, hydrophone is located on three coordinate machine, three coordinate machine is located in full granite solid-state structure, and three coordinate machine measurement apparatus uses full air-flotation type vibration insulation structure, full air-flotation type vibration isolation is located on high-precision air-float guide rail and carries out three coordinate space measurements, also includes being provided with acoustic emission or the support of sound reception simultaneously, and transducer is provided with the angle of pitch and the adjustment axle at the angle that swings on support.
Additionally, in above-mentioned patent application, medical ultrasonic detection method is: utilize hydrophone to measure in the sink, measurement to spatial sound field distribution and time sound-filed simulation carries out the detection of sound parameter, by a three dimensions accurate scan system, it is distributed in order to the room and time of perfect measurement medical ultrasound sound field (acoustic pressure)；What accurate scan system of three-dimensional space uses the fundamental measurement of three coordinate machine, it is achieved the measurement of space sound field；Three coordinate machine uses to be located in full granite solid-state structure and measures, and Three-coordinate measurer uses full air-flotation type vibration isolation, intercepts common vibration interference;Full air-flotation type vibration isolation is located on high-precision three coordinate machine air-float guide rail and carries out three coordinate space measurements.
Above-mentioned medical ultrasonic detection method and system, be used for hydrophone in medical ultrasound, it is possible to successfully detect medical ultrasound first.
No. 200810236253.3 Chinese invention patents of Application No. disclosed in 29 days April in 2009, entitled " medical ultrasonic detection system " of its innovation and creation, it includes a glass flume, glass flume one end in be provided with glass partition, tank is separated into small one and large one two cell bodies by this glass partition.The bottom of two cell bodies communicates, one be arranged on around foregoing glass tank for supporting the X support to granite horizontal guide rail；Described X crossbearer on granite horizontal guide rail has Y-direction granite horizontal guide rail, this Y-direction granite horizontal guide rail and drive it to drive motivation structure along X to the screw mandrel of movement and be connected, the end face of Y-direction granite horizontal guide rail is provided with compressed air inlet port, a horizontal sliding table being arranged on aforementioned Y-direction granite horizontal guide rail, a mounting rod that can move up and down and a transducer fixture.
