Description
Technical field
The present invention relates to ultrasonic imaging technique field, particularly relate to a kind of ultrasonic imaging performance test apparatus and side
Method.
Background technology
When ultrasonic wave emission source and receiver have relative motion, the frequency of sound wave received by receiver with send out
Radio frequency rate is different, and this phenomenon is referred to as Doppler effect.Ultrasound Doppler's method imaging is applied ultrasonic exactly
The Doppler effect of ripple, obtains fluid movement velocity and the information of movement velocity distribution from fluid exterior, carries out
Process and display.Being widely used in the test of fluid movable information, particularly medical science aspect is applied to blood
The inspection of the aspects such as stream, heart and obstetrics.As medical ultrasound imaging equipment, transcranial Doppler blood flow analysis instrument,
Play multiple instruments such as sound fetal heart detector widely used clinically.
When having the particulate producing scattered signal to the ultrasonic wave launched in fluid, according to Doppler effect,
I.e. will produce frequency shift (FS) i.e. Doppler frequency shift f between scattering frequency and tranmitting frequencyd, it is given by:
fd=2vf0cosθ/C
In above formula, v is the movement velocity of scattering object, and C is the speed of ultrasonic wave, and θ is ultrasonic wave acoustic beam and fluid
Angle.By formula it can be seen that frequency displacement is directly proportional to fluid velocity, if detection fd can try to achieve v.
The information of the above-mentioned principle fluid motion of ultrasonic duplex system application is processed, and carries out ultrasonic imaging.
For colorful ultrasonic rheography (CFM, i.e. Color Flow Mapping, or CDFI, i.e. Color Doppler
Flow Imagining), it carries out coloud coding to the fluid velocity obtaining and velocity profile information, accordingly
Position with coding color displays fluid velocity figure；And for ultrasonic Doppler spectrogram, it carries out quick Fu
In leaf transformation, show fluid time dependent fluid velocity spectrogram, it is thus achieved that the speed of internal fluid and speed
Degree distributed intelligence.Ultrasonic Doppler spectrogram has Pulsed-Wave Doppler spectrogram and continuous wave Doppler spectrogram
Two kinds, the former advantage is speed and the velocity profile information that can show select location, and the advantage of the latter
It is to show higher VPV.Medically, ultrasonic color flow figure and spectrogram is applied to show
Show or measure the information of the blood flow movement in blood vessel and internal organs, speed and VELOCITY DISTRIBUTION, and calculate the related heart
Blood vessel parameter, thus carry out medical diagnosis on disease, it is thus achieved that clinical application effect.
But, due to a variety of causes, including theoretic hypothesis, idealization are processed and the restriction etc. of technology,
How to judge that the quantitative measurment color Doppler echocardiography performance of supersonic imaging apparatus includes color blood-stream imaging spirit
Sensitivity, the minimum blood flow detection sensitivity of ultrasonic Doppler spectrogram, peak veloity,PV Detection capability, " Gu
Have video stretching (Intrinsic Spectral Broadening, be called for short ISB) " degree etc. be one very heavy
The problem wanted.
