It will be apparent, however, to one skilled in the art that the application may be practiced without one or more of these details.

Preferred embodiments of the present application are described in detail below, however, the present application may have other embodiments in addition to these detailed descriptions.
Example 1
An embodiment of the present application provides a blood flow parameter monitoring apparatus 100, which is applied to a blood flow parameter monitoring device, where the blood flow parameter monitoring device includes an ultrasonic probe 602, the ultrasonic probe 602 includes a plurality of ultrasonic wafers, and referring to fig. 1, the apparatus includes:
an acquisition module 101, configured to acquire a position of a blood vessel to be monitored by an ultrasonic light spot scanning method;
A determining module 102, configured to determine a first wafer corresponding to the blood vessel to be monitored according to the position of the blood vessel to be monitored;
and the measurement module 103 is used for measuring the blood flow parameters of the blood vessel to be monitored through Doppler ultrasound according to the determined first wafer.
The ultrasonic wafer, for short, is a component for transmitting or receiving ultrasonic waves, and generally occurs in groups, or one transmitting wafer corresponds to a plurality of receiving wafers, or a plurality of transmitting wafers corresponds to one receiving wafer. A group of dies includes a transmitting die and a receiving die. A group of dies may also be referred to as a measurement channel, simply a channel.
The ultrasonic light spot scanning method, also called as M ultrasonic diagnosis method or M ultrasonic method, can image the whole surface of a plurality of wafers, can come out the information in the wafer sound field range, and can rapidly position the blood vessel in the effective range of which wafer.
For reference, the wafer arrangement in M-mode can be seen in fig. 2, i.e. a plurality of wafers are aligned along the radial direction of the blood vessel. The distance between adjacent wafers is C, and the setting of C can be set according to the position of a specific blood vessel, and is generally smaller, so that the blood vessel can be covered more comprehensively.
Further, after M-ary switching to D-ary, a single wafer can be operated, or a plurality of wafers can be operated in parallel. For example, four wafers may be connected in parallel to work together, and the four wafers, shown in brackets in FIG. 2, that is, four adjacent wafers, may be used to more accurately monitor blood flow parameters. T in fig. 2 is the ultrasound time window, i.e. the time required for the sound wave to travel back and forth. The time windows for the different wafers should be the same for the same vessel.
D ultrasound is doppler ultrasound, also known as D ultrasound diagnostic. The Doppler effect principle is applied to detect the blood flow parameters of the blood vessel, and the method has the characteristics of accurate detection and low cost.
The first die may be the die that covers the most vessels in the lateral direction, or the die that has the strongest measurement signal. It is understood that the first cells are grouped, which may also be referred to as a first group of cells.
Since the ultrasonic probe 602 is easily deviated from the blood vessel position due to the movement of the human body during the monitoring, a stable monitoring result cannot be obtained. Therefore, before measurement, the embodiment of the application acquires the position of the blood vessel to be monitored by an ultrasonic light spot scanning method, further determines the first wafer corresponding to the blood vessel to be monitored, and measures the blood flow parameter of the blood vessel to be monitored by the first wafer. In this way, a stable measurement result can be obtained.
In some embodiments, the measurement module 103 is specifically configured to:
acquiring the diameter of the blood vessel to be monitored through Doppler ultrasound according to the determined first wafer;
and acquiring the blood flow parameters of the blood vessel to be monitored again through Doppler ultrasound on the basis of acquiring the diameter of the blood vessel.
Those skilled in the art can know that, on the basis of obtaining the diameter of a blood vessel, the blood flow parameters of the blood vessel to be monitored are obtained through Doppler ultrasound, which is beneficial to more accurately obtaining the blood flow parameters. For example, the blood flow velocity in the blood flow parameters requires knowledge of the propagation time and propagation distance of the ultrasonic wave, and is advantageous for obtaining an accurate propagation distance on the basis of obtaining the blood vessel diameter.
In some embodiments, the measurement module 103 is further configured to:
acquiring a first speed of blood in the blood vessel to be monitored through Doppler ultrasound according to the determined first wafer;
acquiring a first Doppler included angle of the first wafer according to the first speed;
and acquiring the diameter of the blood vessel to be monitored according to the first Doppler included angle.
It will be appreciated that, based on the Doppler effect, a first velocity of blood in the blood vessel, i.e. the flow rate of blood, may be measured.
From the first velocity, a first Doppler angle may be obtained by calculation. The first doppler angle is calculated, for example, by a path of ultrasonic propagation, by a trigonometric function or the like.
Similarly, according to the trigonometric function, the diameter of the blood vessel to be monitored can be calculated through the Doppler included angle and the ultrasonic propagation path.
In some embodiments, the measurement module 103 is further configured to:
acquiring a pulsation curve of the blood vessel to be monitored by an ultrasonic light spot scanning method according to the determined first wafer;
and acquiring a first Doppler included angle of the first wafer according to the pulsation curve and the first speed.
Specifically, the motion path of the acoustic wave of the first wafer in the blood vessel is shown in fig. 3, and the acquired pulsation curve of the blood vessel to be monitored is shown in fig. 4. It will be appreciated that in some cases the first doppler angle may be obtained from other data as well. For example, by any one or more of the speed of sound waves, the transmission path of sound waves, the position of a wafer, and the like, by trigonometric function calculation.
In detail, the first doppler angle can be calculated by the following expression (1):
β=arccos[(V*Δt/L) 1/2 ] （1）
where β is the first doppler angle, V is the first velocity, Δt is the delay of the ultrasonic wave in the upper and lower vessel walls, and L is the distance of the ultrasonic wave inside the vessel walls due to the emission angle. Specifically, Δt is an echo signal formed by the walls of a blood vessel on both sides of a blood vessel in the echo, and is the time difference between the peak and the trough in the pulsation curve. More specifically, the pulsation curve may be echo signals of vessel wall formation on both sides of an arterial vessel. The wall of the arterial vessel is not easily deformed due to compression, so that the measured pulsation curve is more accurate.
In detail, after measuring the first velocity of blood in the blood vessel, the second velocity V0 of blood in the blood vessel can be calculated by measuring the first velocity, and V0 can be the velocity of blood in the blood vessel which is closer to the actual velocity after eliminating the influence of the doppler angle, which is called the actual velocity. The calculation of the actual flow rate is performed as follows expression (2):
V0=V/cosβ （2）
then, according to V0, the ultrasonic wave released by the emitting crystal source can be obtained, and a displacement difference S caused by the emitting angle is generated between the upper and lower blood vessel walls:
S= V0*Δt （3）
from the acoustic path delay of the ultrasound waves within the vessel wall, it is possible to:
cosβ=S/L （4）
substituting expression (3) into expression (4):
cosβ= V0*Δt/L （5）
substituting expression (2) into expression (5):
cosβ=（V/cosβ）*Δt/L （6）
simplifying expression (6), yields:
cosβ=（V*Δt）/（cosβ*L） （7）
and (3) transforming to obtain the following forms:
（cosβ） 2 =（V*Δt）/ L （8）
from expression (8), expression (1) can be obtained.
Referring to fig. 3, from the obtained doppler angle β and the distance L of the ultrasonic wave formed inside the vessel wall due to the emission angle, the diameter of the vessel to be monitored can be obtained:
d = L*cosβ （9）
in some embodiments, the measurement module 103 is further configured to:
acquiring a deviation angle of the Doppler included angle of the first wafer according to the first speed;
acquiring the first Doppler included angle according to the deviation angle and a second Doppler included angle preset by the first wafer; the first Doppler included angle is an actual Doppler included angle of the first wafer, and the second Doppler included angle is a Doppler included angle preset by the first wafer.
In this embodiment, the second doppler angle may be 60 degrees, and then:
β=60+α （10）
where α is the deviation angle and can take a negative value.
Substituting expression (10) into expression (8) yields:
α=arccos[(V*Δt/L) 1/2 -60] （11）
it will be appreciated that the deviation angle is obtained, and the situation that the ultrasonic probe 602 deviates from the blood vessel position can be known more accurately.
In some embodiments, the measurement module 103 is further configured to:
on the basis of acquiring the diameter of a blood vessel, acquiring a plurality of spectrum envelopes obtained by measuring a plurality of ultrasonic wafers through Doppler ultrasound, and correcting a first Doppler included angle of the first wafer according to the plurality of spectrum envelopes;
and acquiring the blood flow parameters of the blood vessel to be monitored according to the corrected first Doppler included angle.
It can be understood that the first doppler angle is obtained first, then the vessel diameter is obtained through the first doppler angle, and on the basis of obtaining the vessel diameter, a plurality of spectrum envelopes obtained by measuring a plurality of ultrasonic wafers are obtained through doppler ultrasound.
Because of the movement of the human body, the ultrasound probe 602 is easily deviated from the position of the blood vessel, so that the mutual position relationship between the ultrasound probe 602 and the blood vessel to be monitored is not too stable, and the trend of the blood vessel itself may be in a less regular, curved or bent condition, so that the measured value of the Doppler included angle measured before may have an error. Therefore, in this embodiment, the measured value of the doppler angle can be adjusted through the spectrum envelopes of the multiple channels.
Alternatively, the channels may be symmetrically distributed along the blood flow direction in the detection area of the blood vessel to be monitored by an even number of channels. As described above, if the ultrasonic probe 602 is placed at an error location, the calculated doppler angles of the two channels are opposite in error direction, and thus, once the two are averaged, most of the errors can be cancelled out, and the doppler angle value is corrected.
And then, the corrected Doppler included angle is used as a parameter, the spectrum envelope curve is adjusted, and further, the blood flow parameter of the blood vessel to be monitored is obtained again, so that more accurate blood flow parameters can be obtained. Specifically, the Doppler angle may be corrected multiple times. The more the number of corrections, the smaller the error.
In some embodiments, the apparatus further comprises:
an anomaly identification module for determining whether the blood flow parameter measured by the measurement module 103 exceeds a preset range; if the preset range is exceeded, the following steps are executed:
acquiring the position of a blood vessel to be monitored by an ultrasonic light spot scanning method;
determining a first wafer corresponding to the blood vessel to be monitored according to the position of the blood vessel to be monitored;
measuring the blood flow parameters of the blood vessel to be monitored through Doppler ultrasound according to the determined first wafer;
Otherwise, the following steps are executed:
and measuring the blood flow parameters of the blood vessel to be monitored through Doppler ultrasound according to the determined first wafer.
If the measured data exceeds the preset range, it is indicated that the measured data is abnormal, possibly due to human body movement, and the first wafer deviates from the original position. Therefore, the wafer corresponding to the blood vessel to be monitored needs to be redetermined, and thus the steps performed by the acquisition module 101, the determination module 102, and the measurement module 103 need to be performed again, i.e., all modules are performed once. Otherwise, the steps performed by the measurement module 103 need only be repeated.
In order to better understand the blood flow parameter monitoring device 100 provided in the embodiment of the present application, the following describes the implementation process of the blood flow parameter monitoring device 100 provided in the embodiment of the present application. Fig. 5 is a flow chart illustrating an implementation process of the blood flow parameter measurement device according to an embodiment of the present application, and referring to fig. 5, the implementation process may include:
step 201: acquiring the position of a blood vessel to be monitored by an ultrasonic light spot scanning method;
step 202: determining a first wafer corresponding to the blood vessel to be monitored according to the position of the blood vessel to be monitored;
Step 203: and measuring the blood flow parameters of the blood vessel to be monitored through Doppler ultrasound according to the determined first wafer.
Fig. 6 is a detailed flowchart of an implementation process of the blood flow parameter measurement device according to an embodiment of the present application, and referring to fig. 6, the implementation process may include:
step 301: data were collected by M-ultra. The data can be acquired through an ultrasonic light spot scanning method, and can be synchronously acquired through a plurality of ultrasonic acquisition channels. Specifically, if a certain channel is found to not detect the target detection object, the acquisition function of the ultrasonic acquisition channel can be closed.
Step 302: and (5) preprocessing data. For example, the data is sorted, classified, etc., and the data with wrong format can be removed, namely, the data preprocessing mainly carries out data processing in a form.
Step 303: m-ary motion imaging. Ultrasonic imaging is to scan a human body by using an ultrasonic sound beam, and to obtain an image of an organ in the body by receiving and processing reflected signals. There are a variety of ultrasound instruments in common use: the M-ary (spot scanning type) is a graph showing the movement of a spot at different times, with the vertical direction representing the spatial position from shallow to deep and the horizontal direction representing time.
Step 304: and (5) identifying the position of the blood vessel. Since the longitudinal axis of the M-ary can represent a spatial position from shallow to deep, the position of the blood vessel can be identified. Specifically, since the blood vessel position is relatively fixed at the position of the human body and the human body moves to deviate the ultrasonic probe 602 from the blood vessel position, the positional relationship between the blood vessel and the ultrasonic probe 602 needs to be determined. Therefore, the position of the blood vessel is represented by the corresponding ultrasound probe 602, and the position is deviated from the original corresponding ultrasound probe 602.
Step 305: and determining the wafer corresponding to the blood vessel position. I.e. determining the first wafer or the first group of wafers as described above.
Step 306: blood flow velocity is obtained by D-ultrasound. I.e. the first speed described above is obtained.
Step 307: pulse cycle data of the artery are acquired by means of M-ultrasound. I.e. the above-mentioned pulsation curve is obtained.
Step 308: and obtaining the Doppler included angle. I.e. the first doppler angle described above is obtained. After the first doppler angle is obtained, the second velocity may be calculated.
Step 309: the vessel diameter is obtained. I.e. the vessel diameter d described above is obtained.
Step 310: blood flow velocity was again acquired by D-ultrasound. I.e. the first speed described above is obtained. On the basis of acquiring the diameter of the blood vessel, the acquired first speed is more accurate, and then the first Doppler included angle is acquired according to the first speed. The first doppler angle and the first velocity may be iterated a number of times to obtain a more accurate value.
Step 311: the spectrum is acquired and displayed. And converting the data about blood flow acquired by the channel into a spectrogram and displaying the spectrogram.
Step 312: the spectral envelope is acquired and displayed. Similarly, the envelope curve of the spectrogram is obtained through calculation and displayed.
Step 313: and analyzing, calculating and displaying blood flow parameters. On the basis of the envelope curve, analysis and calculation are carried out, and relevant blood flow parameters are obtained and displayed. It will be appreciated that the display of step 312 and this step may be displayed together, for example, the envelope of the spectrogram may be displayed on the upper half of the screen and the blood flow parameters may be displayed on the lower half.
Step 314: and (5) identifying abnormal blood flow parameters. If the blood flow parameter exceeds the preset range, it indicates that the measured data is abnormal, possibly due to human body movement, and the first wafer deviates from the original position. Therefore, the wafer corresponding to the blood vessel to be monitored needs to be redetermined, and thus, step 301 needs to be returned, and all the steps are performed in sequence. Otherwise, it is only necessary to return to step 310 to perform measurement of the blood flow parameter.
