Description
Technical field
The present invention relates to a kind of supersonic detection method, particularly a kind of use of Portable medical supersonic detection means
Method.
Background technology
Ultrasonic application in medical treatment is just becoming more and more important.From its application, we substantially can be by medical ultrasound
It is divided into diagnostic ultrasound and treat ultrasonic two application directions.
The application of diagnostic ultrasound is more ripe at present, surpasses (A-mode) from A, B ultrasonic (B-modc), and C surpasses (C-mode)
Surpass (M-mode) to M, and adopt the B ultrasonic of higher hamonic wave imaging, species is various, and technology is relatively ripe.
Recent years, treatment is ultrasonic to have breakthrough, in terms of focus ultrasonic knife, ultrasonic rubble successively in terms of clinical practice
Obtain 7 great development, particularly focus ultrasonic knife (i.e. High Intensity Focused Ultrasound High Intensity Focal Ultrasound
(HIM) there is the development in the leading world in China, there is very big application prospect.However, the extensive application with medical ultrasound
Compare, the restraining factors of its development similarly significantly show..
The application of medical ultrasound, is a kind of accurate application to ultrasonic sound field, in theory, it is right that this application first has to
Medical ultrasound sound field has the description of complete and accurate and measures.But, due to particularity and the tissue of ultrasonic measurement
The complexity of structure, result in the accurate description to ultrasonic sound field in human body and measurement is all extremely difficult.Therefore, to medical ultrasound
Application be to have walked a road first applied.I.e. under the conditions of having the description of sound field substantially, first carry out applications of ultrasound, obtain
Zoopery and the medical experience of clinical practice, as later guidance.The sound field facing the difficulty accurately describes and measures, and gives over to
Solve again later.
In this case, the medical application of medical ultrasound is just taken an early lead, and achieves and make common people gaze at
Achievement, its diagnosis and therapeutic effect obtain the extensive approval of medical circle.However, we oneself through determining medical ultrasound effect
In the case of, is still in its acoustic measurement, oneself is through answering immature, incomplete stage with the success of medical ultrasound
With compare it may be said that medical ultrasound application aspect, the contribution that physician is done is greater than acoustician.As former sound field
Space measurement scans mode using screw drive space, limited by its precision and measurement range, does not far reach the requirement of IEC standard.
However, in today of electronic technology and computer technology fast development, if acoustic measurement can be with up-to-date technology
Combine it is believed that being to be entirely possible to break through original measurement limitation, to reach the need tentatively meeting clinical medicine application
Will.
It is known that medical supersonic equipment is in disease diagnosis and therapy, in order to ensure the effect of Clinics and Practices, need
Ultrasonic image clearly, however, image is more clear, the output acoustic power of diagnostic ultrasound equipment will be bigger, excessive ultrasonic output
Power will produce biological change in some instances it may even be possible to cause deformity of fetus etc. to tissue.Therefore, safety should be ensured, and
Image clearly to be reached has become the main body of conflict with biological effect.Use ultrasonic device in order to ensure safety, carry in industry
Go out the problem that medical supersonic equipment is used ultrasonic secure threshold.For that purpose it is necessary to enter to the sound parameter of medical supersonic equipment
Row evaluates the security it is ensured that in clinical practice.
Hydrophone, also known as underwater microphone, is transducer underwater signal being converted to electric signal.It is to utilize material
Characteristic and its interact with surrounding environment a variety of mudulation effects producing, detect the signal such as pressure, sound in liquid
Instrument.In civil area, hydrophone can carry out oil exploration, marine organisms monitoring, seabed investigation by detecting underwater sound signal
Deng.In military field, hydrophone as sonar system foremost, carries the effect detecting unfriendly target signal.Water is listened
Device is used for medically, then can be used to detect ultrasonic in medical supersonic equipment, whether to measure these ultrasound value in safety
Within range of receiving.
