Description
Technical field
The invention belongs to ultrasonic therapy technical field and in particular to a kind of ultrasonic energy output-controlling device, comprise this surpass
The ultrasonic therapeutic apparatus of acoustic energy output-controlling device and ultrasonic energy output control method.
Background technology
High intensity focused ultrasound（High Intensity Focused Ultrasound, abbreviation HIFU）Treatment method is
The new method of the non-invasive therapy that developed recently gets up.High-strength focusing ultrasonic therapy equipment is as treatment source, profit using ultrasonic wave
With ultrasonic wave directionality good in biological tissues, penetrability and can the physical characteristic such as focusing, by external low energy densities
Focusing ultrasonic wave in biological internal target tissue, to form high sound intensity focus, the height assembled by focal point in target tissue
Fuel factor, mechanical effect and the cavitation effect that the ultrasonic wave of energy density produces is destroying such as tumour, Ai Deng non-normal tissue
Cell, realizes the purpose of non-invasive therapy.Over the course for the treatment of, the ultrasonic wave of the high-energy-density that focal point is assembled can make to be shone
There is coagulation necrosis in the tissue penetrating position, and for the normal structure beyond focus, the ultrasonic energy that absorbed by it
Metric density is relatively low, can be taken away the ultrasonic energy that it is absorbed by internal blood circulation, thus typically will not focusing with
Outer tissue causes to damage.
Generally, in high-strength focusing ultrasonic therapy equipment, it is the driving effect using ultrasonic transducer in driver element
Under be generated and transmitted by ultrasonic wave.Wherein, driver element provides electric energy, the piezoelectric in ultrasonic transducer for ultrasonic transducer
There is piezo-electric effect under electric field action, thus converting electrical energy into the mechanical energy of ultrasound modalities, being over the course for the treatment of
The focusing ultrasonic wave that ultrasonic transducer is sent destroys such as tumour, cancer thus reaching in biological internal target target tissue
Purpose in non-normal tissue's cell.
At present, the driver element in ultrasonic therapeutic apparatus is typically with constant pressure type type of drive or constant current mode driving side
Formula is driving ultrasonic transducer to export ultrasonic energy, but the fluctuation due to driving voltage, the change of driving current and ultrasonic
In transducer, the many factors such as depolarization of piezoceramic material affect the stability of the ultrasonic energy of ultrasonic transducer transmitting；
Simultaneously as the propagation after ultrasonic wave entrance biology is internal is easily subject to the factor such as media variations, interface reflection, use environment
Impact, the ultrasonic energy leading to be actually reached biological internal target tissue is variant with the dosage required for actual therapeutic,
Thus may result in futile treatment or the situation generation of over-treatment, futile treatment can affect the curative effect treated, over-treatment
The hidden danger that secure context can be brought to treatment even can make biological internal normal structure be destroyed.
The output acoustic power of ultrasonic transducer（Ultraphonic agent amount）It is a basic thing weighing ultrasonic energy size in sound field
Reason amount, and described output acoustic power is related to the electrical power of this ultrasonic transducer.In the prior art, typically adopt constant pressure type
Type of drive or constant current mode type of drive controlling the output acoustic power of ultrasonic transducer, that is, after the completion of ultrasonic transducer manufacture
First measure the corresponding output acoustic power under different driving voltage or driving current of ultrasonic transducer, over the course for the treatment of, lead to
Overregulate the driving voltage of ultrasonic transducer or driving current to obtain required ultrasonic energy.But it was verified that using permanent
Although pressure type type of drive can keep voltage constant constant, electric current still can with the ultrasound emission material in ultrasonic transducer with
And the change of ultrasonic passage and change, therefore electrical power cannot be able to keep invariable therewith changing, correspondingly, its output sound
Power also will change therewith；In the same manner, electrical power similarly cannot be kept invariable using constant current mode type of drive, because
And also just cannot ensure the constant of output acoustic power.Even if taking measures driving voltage or driving current to be detected and feeds back
Control, so that the output acoustic power of ultrasonic transducer can recover to required steady state value within a period of time, but wait until
When feedback circuit adjusts output acoustic power to steady state value, futile treatment or over-treatment often have occurred and that.Because generally entering
The time of row ultrasonic therapy is natively very short, typically not over half a minute it is desirable in a short period of time by ultrasonic transducer
Output acoustic power adjust to steady state value it is clear that being difficult to.
In summary, existing ultrasonic therapeutic apparatus are carried out to the ultrasonic energy of ultrasonic transducer output over the course for the treatment of
The occurrence of technological means of definite effective control can not reduce malpractice well.Based on improve treatment security and
Reduce the consideration of malpractice, how to be lifted enables the output of ultrasonic energy to control to have become as in the range of safe dose
