Drive parameters.
超声探头自适应匹配系统的第三种改进，利用超声探头的识别信息在探头数据库进行匹配获取得到超声探头对应的探头属性参数，再根据探头属性参数获取到超声探头的探头驱动参数，进而根据探头驱动参数驱动超声探头工作，实现多种超声探头与超声诊断设备主部件的快速匹配使用，提高超声诊断设备应用的灵活性。The third improvement of the ultrasonic probe adaptive matching system is to obtain the probe attribute parameter corresponding to the ultrasonic probe by using the identification information of the ultrasonic probe in the probe database, and then obtain the probe driving parameter of the ultrasonic probe according to the probe attribute parameter, and then according to the probe The driving parameters drive the ultrasonic probe to realize the rapid matching of various ultrasonic probes and the main components of the ultrasonic diagnostic equipment, and improve the flexibility of application of the ultrasonic diagnostic equipment.
作为上述技术方案的进一步改进，探头驱动参数包括发射脉冲频率和/或扫描线数量和/或探头延迟发射时间和/或扫描线-扫描线夹角和/或探头工作距离。为了使超声探头能够正常工作，本实施例中选用发射脉冲频率、扫描线数量、探头延迟发射时间、扫描线-扫描线夹角、探头工作距离这五个探头驱动参数来驱动超声探头。下面具体说明由探头属性参数得到探头驱动参数的方法：As a further improvement of the above technical solution, the probe driving parameters include the transmitting pulse frequency and/or the number of scanning lines and/or the probe delayed emission time and/or the scanning line-scanning line angle and/or the probe working distance. In order to enable the ultrasonic probe to work normally, in the embodiment, the five probe driving parameters of the transmitting pulse frequency, the number of scanning lines, the probe delayed emission time, the scanning line-scanning line angle, and the probe working distance are used to drive the ultrasonic probe. The method for obtaining the probe driving parameters from the probe attribute parameters is specifically described below:
第一，超声探头的中心频率即发射脉冲频率。First, the center frequency of the ultrasonic probe is the transmitted pulse frequency.
第二，获取阵元数，则扫描线数量是阵元数的整数倍，例如扫描线数量是阵元数的2倍；这一倍数根据超声探头自适应匹配系统的不同而不同，可根据需要自由设置。Second, to obtain the number of array elements, the number of scan lines is an integer multiple of the number of array elements. For example, the number of scan lines is twice the number of array elements; this multiple is different according to the ultrasonic probe adaptive matching system, and can be as needed Free to set.
第三，扫描线-扫描线夹角的计算公式为：Third, the calculation formula of the scan line-scan line angle is:
扫描线-扫描线夹角＝((阵元间距*阵元数)/(π*曲率半径*扫描线数量))*180。Scan line-scan line angle = ((array spacing * array element number) / (π * curvature radius * number of scanning lines)) * 180.
第四，焦距是用于判断超声探头在默认状态下的显示深度，即超声探头的默认工作距离；例如焦距为20mm，那么系统在初始默认显示深度一般在40mm左右，深度20mm附近是探头的最常用临床应用距离。Fourth, the focal length is used to judge the display depth of the ultrasonic probe in the default state, that is, the default working distance of the ultrasonic probe; for example, the focal length is 20 mm, then the system is generally at the initial default display depth of about 40 mm, and the depth of 20 mm is the most probe. Common clinical application distance.
最后，不同的超声探头类型，其探头延迟发射时间的计算公式不同。针对凸阵探头的探头延迟发射时间的计算方法如下：Finally, different ultrasonic probe types have different formulas for calculating the probe delay emission time. The method for calculating the delayed emission time of the probe for the convex array probe is as follows:
以阵的弧心为原点，在N个阵元工作时，选取坐标轴及阵在XOY平面上的投影如图2所示，图2是本发明超声探头自适应匹配系统一个实施例的阵在XOY平面上的投影示意图，且假设N为偶数。γ是第i个阵元的矢径与x轴间的夹角，若相邻阵元之间的夹角为β，则有Taking the arc center of the array as the origin, when the N array elements work, the projection of the coordinate axes and the array on the XOY plane is as shown in FIG. 2, and FIG. 2 is an array of an embodiment of the ultrasonic probe adaptive matching system of the present invention. Schematic representation of the projection on the XOY plane, and assumes that N is an even number. γ is the angle between the vector of the i-th array element and the x-axis. If the angle between adjacent elements is β, then

Figure PCTCN2018111219-appb-000001
其中：γ中的i是小脚标，其他类似。β＝((阵元间距)/(π*曲率半径))*180。Among them: i in γ is a small footer, others are similar. β = ((array spacing) / (π * curvature radius)) * 180.
a为曲率半径；R i是第i个阵元到焦点P的声程，以
Figure PCTCN2018111219-appb-000002
即F表示焦距，则有 a is the radius of curvature; R i is the sound path from the ith array element to the focus P,
Figure PCTCN2018111219-appb-000002
That is, F represents the focal length, then there is
R i＝[a 2+(a+F) 2-2(a+F)cosγ] 1/2 R i =[a 2 +(a+F) 2 -2(a+F)cosγ] 1/2
＝[4a(a+F)sin 2(γ/2)+F 2] 1/2 =[4a(a+F)sin 2 (γ/2)+F 2 ] 1/2
若以声程
Figure PCTCN2018111219-appb-000003
即F作为参考，则第i个阵元到焦点P的声程与参考声程之差，即R i与F之差为 Sound path
Figure PCTCN2018111219-appb-000003
That is, F is used as a reference, and the difference between the sound path of the i-th array element and the focus P and the reference sound path, that is, the difference between R i and F is
ΔR i＝[4a(a+F)sin 2(γ/2)+F 2] 1/2-F ΔR i =[4a(a+F)sin 2 (γ/2)+F 2 ] 1/2 -F
为使N个阵元所辐射的声波在焦点P处都能同向叠加，第i个阵元的延迟时间为In order to make the sound waves radiated by the N array elements superimposed in the same direction at the focus P, the delay time of the i-th array element is
t fi＝-ΔR i/c+t 0＝-{[4a(a+F)sin 2(γ/2)+F 2] 1/2-F}/c+t 0 t fi =−ΔR i /c+t 0 =−{[4a(a+F)sin 2 (γ/2)+F 2 ] 1/2 -F}/c+t 0
式中：t 0是一个足够大的时间常数，以避免t fi出现负值，或者是相当于N个阵元中心点辐射声波脉冲的时刻。 Where: t 0 is a sufficiently large time constant to avoid a negative value of t fi or a moment equivalent to the radiation pulse of the center point of the N elements.
而针对线阵探头，则采用如下公式计算探头延迟发射时间：For linear array probes, the probe delay transmission time is calculated using the following formula:
Figure PCTCN2018111219-appb-000004
Figure PCTCN2018111219-appb-000004
而相控阵探头以及矩阵探头的探头延迟发射时间的计算方法为超声探头数据处理领域的常用方法，不再赘述。The calculation method of the probe delay emission time of the phased array probe and the matrix probe is a common method in the field of ultrasonic probe data processing, and will not be described again.
