The key technology that this utility model can also relate to comprises the key technology of pressure arteries and veins figure electrocardiosignal analysis, key technology and the depression of order analysis that data image is handled.
1, the key technology of pressure arteries and veins figure electrocardiosignal analysis
(1) complicated collection---10Hz frequency sampling:
Electrocardio and pressure transducer sample frequency were 100 point/seconds, promptly adopt a point every 10ms, in the humorous wave component of pressure pulse wave, harmonic components more than 10 times is little of ignoring fully, therefore, all can satisfy the law of sampling to the pulse frequency that is no more than 300 times/minute: moving object is when resembling, and repetition rate promptly is equivalent to sample frequency, should be higher than 2 times of information peak frequency.Therefore, the pressure signal sample frequency is 100Hz, and drop-out neither can be because of the too close redundant data that produces of sampling yet.Synchronous acquisition radial artery pressure arteries and veins figure and II lead electrocardiogram, through A/D converter, are digital signal with image transitions, and input computer and B ultrasonic signal are preserved synchronously.
(2) simplification is analyzed---and differential analysis and electrocardio and pressure arteries and veins figure's cuts apart:
Differential analysis is one of fundamental analysis method of time domain arteries and veins map analysis.Differential by to electrocardio and pressure arteries and veins diagram data can obtain the rate of change of data to the time.
Pulsation is an outward manifestation aroused in interest, to the cutting apart automatically of arteries and veins figure, is arteries and veins the figure important and basic work of identification automatically according to cardiac cycle, and the basic ideas of program are
[7]: because the derivative value of R ripple is more much higher than other parts in the electrocardiogram, therefore can find appropriate threshold to obtain the information of preliminary R ripple position from Electrocardiographic differential map, the peak of seeking arteries and veins figure again in the follow-up neighborhood of this position is the R ripple.Can know from the formation mechanism of each road signal, impedance diagram, pressure arteries and veins figure and the starting point that refers to volume arteries and veins figure are certainly all in the neighborhood after the R ripple, know the position of R ripple, in its follow-up neighborhood, sought the starting point that maximum point or smallest point can obtain other three road signals.
(3) complicated comprehensive---the stack of pressure arteries and veins figure:
Because the many external influence factors in gatherer process and the physiological and pathological of human body self change, when the human body quiescent condition, sizable fluctuation still appears in the arteries and veins graph parameter.After the cutting apart of electrocardio and pressure arteries and veins figure, superpose automatically and calculation of parameter, smoothly to fall effect of noise.Continuously arteries and veins figure stack is by the starting point of the arteries and veins figure in this cardiac cycle and the terminating point of arteries and veins figure (also being the arteries and veins figure starting point of next cardiac cycle) work one straight line, is the figure behind the baseline calibration after arteries and veins figure each point and straight line respective point are subtracted each other.Is that para-position stack back, center is average with the arteries and veins figure after each calibration with separately peak, the arteries and veins figure after promptly obtaining superposeing; After analyzing respectively by the arteries and veins graph parameter of each time period, discontinuous arteries and veins figure stack averages and standard deviation embodies.
2, the key technology of data image processing
The kinestate of the area on the wrist over the radial artery where the pulse is felt for diagnosis radial artery is by the scanning of Type B machinery ultrasonic probe, the image that obtains is through D/A, mould/number conversion, be stored into computer with digital signaling, the original image processing system is divided into three flow processs: image pretreatment stage, feature extraction stage, discriminatory analysis stage.Three phases also is the imbody of " complicated-simple-complexity " thinking.
(1) complicated image storage---along with the contraction of heart, pulse wave conducts to radial artery, radial artery shrinks the radial motion of diastole, its cross section axle center is periodically reciprocating motion simultaneously, Type B machinery Ultrasound Instrument (12 frame/second) record with 10MHz, synchronous frequency is stored in computer (15 frame/second), calculate for 75 times/minute with heart rate, nearly 10 two field pictures of each cardiac cycle are in order to characterize the characteristic point of radial artery periodic movement, in 20～30s of continous-stable sampling, can write down the complete procedure of radial artery motion, the synchronous recording electrocardiosignal, pressure of the radial artery force signal (100Hz), a large amount of two-dimensional ultrasonic images have reflected the overall process of body surface bio information.
(2) oversimplify date processing---continuously dynamic ultrasonoscopy is resolved into immobilized single-frame images, discern radial artery edge in every frame original image, and digitized processing.The notable attribute of local brightness variation in the image is selectively strengthened, and the unwanted feature that decays adopts high-pass filtering, outstanding radial artery edge suppresses non-marginal information in the image, makes image contour more clear; Adopt the method for average or integration to remove smooth noise, as far as possible the details of holding tube cavity edge; Adopt the method sharpening image of differential, strengthen the HFS in the image spectrum, just be equivalent to from former image, deduct its low frequency component; The vascular precise region is divided into several and has predicable, mutually disjoint pixel zonule, thereby set is communicated with, and multiple gray threshold is set, and the radial artery zone of preliminary election is converted to black and white binary image; Based on morphology Useful Information is carried out feature extraction, reduce quantity and shape and position or the like quantity of information of the marking area of length, brightness, width, local brightness variation.Carry out formalization expression and description according to the surface in zone.
After the interframe relation of (3) complicated three-dimensional structure the---single frames data image radial artery Boundary Recognition and sequence chart is determined, can carry out three-dimensional reconstruction.At first activate A plane or B plane, C plane,, central point is placed the area on the wrist over the radial artery where the pulse is felt for diagnosis radial artery district, by rotation X, Y or Z axle, choose the optimal viewing direction then by the structure of parallel mobile the area on the wrist over the radial artery where the pulse is felt for diagnosis radial artery.Reconstruct mode is selected the adjustable mixed model of percentage ratio of the minimum echo mode of transparent image, surface imaging pattern, combination.The minimum echo mode of transparent image only receives minimum echo information on the sound beam direction, is suitable for observing anechoic structures such as blood vessel; The surface imaging pattern receives the nearest echo of distance probe on the sound beam direction, is suitable for the surface information of tissues observed structure, specifically is used for the information characteristics such as chamber wall that Reconstruction of vessel can be used for observing blood vessel.Rotation that can be by X, Y, Z-direction after the reconstruction, adjust the area on the wrist over the radial artery where the pulse is felt for diagnosis radial artery district size, regulate 3-D view gain and S curve, add the pseudo-color of different colours to obtain to be suitable for the best 3-D view of human eye to organizational structure identification.
