Description
Technical field
The present invention relates generally to medical technology more particularly to a kind of ultrasonic system and a kind of use ultrasonic system obtains mesh
The method for marking the two-dimension elastic figure of tissue.
Background technology
As a kind of emerging Angiography, the elastography based on shearing wave achieves larger in recent years
Development.In general, it can determine some mechanical properties of biological tissue, such as viscoelastic by carrying out shearing wave elastogram
Property, and then, it can assist determining whether the specific tissue is associated with certain pathological symptoms by the viscoplasticity information of acquisition.
The motive force generated by external vibrator would generally be applied to destination organization when actually carrying out shearing wave elastogram, at this
Shearing wave is generated under the action of motive force inside destination organization；And ultrasonic signal is emitted by ultrasonic probe and is received anti-
It is emitted back towards the ultrasound echo signal come.It is then possible to specifically handled by the ultrasound echo signal received to these, from
And can determine the various characteristics parameter in the shearing wave of destination organization internal communication, for example, the spread speed of shearing wave.Due to
There is determining relationship between the characterisitic parameter of the shearing wave of destination organization internal communication and the mechanical property of destination organization, because
This, destination organization is may further determine that out based on the determining shearing wave characterisitic parameter (for example, spread speed of shearing wave)
Mechanical property, for example, viscoplasticity etc., destination organization is analyzed, diagnosed or is treated with auxiliary.
In the realization of the elastography based on shearing wave, usually there are two types of configuration modes for vibrator.One kind is straight
It scoops out and is positioned near object to be measured tissue with individual external vibrator, to generate the mechanical wave needed.However, this match
Put that mode is very inconvenient for the operation of doctor, because doctor needs to operate operation interface in Ultrasound Instrument, ultrasonic probe simultaneously
And said external vibrator.In this way, a doctor is difficult to operate above three part simultaneously, other staff's progress is generally required
Auxiliary operation so wastes manpower, reduces efficiency.Another configuration mode is that vibrator directly is embedded into ultrasonic probe
Inside.However, this configuration mode is since vibrator is embedded into ultrasonic probe, therefore the size of ultrasonic probe will be corresponding
Increase, and cost can also increase.In addition, the small function that the function of Ultrasound Instrument application vibrator, which is only it, to be had,
It does not all need to many times using this function, however, being difficult then that embedded shakes in the case of the function of not needing to vibrator
Dynamic device is disassembled from ultrasonic probe.In short, the realization of existing most of elastographies based on shearing wave is uncomfortable
Clinical setting is closed to use.Because the vibrator used in these existing realizations it is usually very big and very complicated or
Use will be very expensive in clinical setting.
Therefore, it is necessary to a kind of improved system is provided and determines the characteristic of destination organization using this improved system
The method of parameter is as described above at least one to solve the problems, such as.
