Referring to fig. 2, fig. 2 is a flowchart of a method for adjusting a doppler parameter value according to an embodiment of the present application, where the method is applied to an ultrasound apparatus 10, and the method includes:
201. in a first examination mode unfocused ultrasound waves are transmitted to a target region according to target doppler parameters.
In this embodiment, the processor 105 may transmit unfocused ultrasound waves to the target region in accordance with the target doppler parameters in the first inspection mode. The target Doppler parameters comprise at least one of emission angles of unfocused ultrasonic waves, scanning depths of the unfocused ultrasonic waves, scanning densities of the unfocused ultrasonic waves, emission frequency points of the unfocused ultrasonic waves, color Doppler sampling frames and pulse Doppler sampling lines. The first inspection mode includes at least one of the following inspection modes: a thyroid examination mode, a carotid examination mode, a breast examination mode, a neurological examination mode, an adult abdominal examination mode, an obstetrical OB examination mode, a renal examination mode, a fetal cardiac examination mode, an adult abdominal examination mode, and a transcranial doppler TCI examination mode.
The unfocused ultrasonic wave includes a plane wave or a divergent wave, and may be of other wave types, which is not limited in particular. The plane wave can cover the range of one frame of image area by one-time emission, the imaging speed is high, the operation convenience of a user can be improved, and the visual experience is better. If the focused wave is adopted, the experience effect of the user may be poor because the imaging speed of the focused wave is slower than that of the plane wave.
In one embodiment, the target region may be a face, a spine, a heart, a uterus, a pelvic floor, or the like, or other parts of human tissue, such as a brain, a bone, a liver, or a kidney, and is not limited herein.
202. And receiving the ultrasonic echo of the unfocused ultrasonic wave returned from the target area to obtain ultrasonic echo data.
In this embodiment, the processor 105 may receive an ultrasound echo of an unfocused ultrasound wave returned from the target region, and obtain ultrasound echo data. That is to say, after the unfocused ultrasonic wave is emitted to the target region, the target region may return an ultrasonic echo corresponding to the ultrasonic wave, and the ultrasonic echo is processed to obtain ultrasonic echo data.
203. And obtaining an ultrasonic blood flow image corresponding to the target area according to the ultrasonic echo data.
In this embodiment, at least two frames of ultrasound blood flow images corresponding to the target region may be obtained according to the ultrasound echo data, and it is understood that data processing such as amplification, digital-to-analog conversion, and beam forming may be performed when generating the ultrasound blood flow image, and the ultrasound blood flow image may be a B-mode image, a doppler image, a color blood flow image, or a combined display image of the above images, which are formed through signal processing.
After the ultrasonic blood flow image corresponding to the target area is obtained, since the blood flow velocity changes from low velocity to high velocity from the blood vessel wall to the center of the blood vessel in the blood vessel to be actually detected, the blood flow has different moving directions (flowing to the ultrasonic probe and far from the ultrasonic probe) relative to the ultrasonic probe and is represented by two colors of red and blue in the actual image. If the pulse repetition frequency is insufficient, the high velocity blood flow data in the blood vessel will undergo a color reversal from reddish to bluish or bluish to reddish. By correcting a portion where the abrupt change in color exceeds the threshold value by the color inversion correction function, the color in which the portion is inverted can be corrected back to the correct direction. For a plurality of pieces of cocurrent blood flow data, in some frames with too much data, a problem that a plurality of pieces of blood flow data are connected together and cannot be distinguished occurs. By setting higher threshold value data, blood flow data with lower threshold values are deleted, data with higher flow speed are reserved, and a plurality of homodromous blood flows can be effectively distinguished.
204. A target blood flow in the ultrasound blood flow image is determined according to the first examination mode.
In this embodiment, the processor 105 may determine the target blood flow in the ultrasound blood flow image according to the first examination mode. Specifically, the processor 105 performs doppler data analysis on the ultrasound blood flow image to obtain an analysis result, where the analysis result includes at least one blood flow type (for example, blood flow types of small blood flow, large blood vessel, and the like); a target blood flow in the ultrasound blood flow image is determined based on the analysis results and the first examination mode. That is, the processor 105 may perform doppler data analysis on the ultrasound blood flow image, for example, classify the ultrasound blood flow image according to the flow velocity of blood flow, the doppler coverage area of blood flow, or the display form of blood flow, so as to distinguish large blood vessels or small blood flow in the target region, that is, an analysis result, and at the same time, the examination region corresponding to different examination modes or the types of blood flow to be examined are different, for example, the first examination mode is a thyroid gland examination mode, and the thyroid gland only needs to pay attention to small blood flow for examination of the thyroid gland. Since the at least one blood flow type is obtained by doppler data analysis of the ultrasound echo data, a target blood flow in the ultrasound blood flow image can be determined from the first examination mode and the analysis result.
205. The parameter value of the target doppler parameter is adjusted based on the target blood flow.
In this embodiment, the processor 105 may adjust a parameter value of the target doppler parameter based on the target blood flow, and specifically, may adjust the parameter value of the target doppler parameter according to the analysis result and the target blood flow in the ultrasound blood flow image. The following is a detailed description of how to adjust the parameter value of the target doppler parameter according to the target blood flow:
1. when the target doppler parameter includes the emission angle of the unfocused ultrasound waves, the processor 105 may adjust the emission angle of the unfocused ultrasound waves to a first preset threshold according to the blood flow type of the target blood flow, wherein the first preset threshold corresponds to the blood flow type of the target blood flow. For example, if the blood flow type of the target blood flow is a small blood flow type, the emission angle of the unfocused ultrasound waves may be adjusted to a first preset threshold based on the small blood flow type, that is, the setting of the first preset threshold may be set by the user according to previous ultrasound scanning experience to a value most suitable for the small blood flow type, for example, the value may be the value with the best imaging effect or the value with the richest acquired data, and is not limited specifically.
2. When the target doppler parameter includes at least one of the scanning depth of the unfocused ultrasonic wave, the scanning density of the unfocused ultrasonic wave, and the emission frequency point of the unfocused ultrasonic wave, the processor 105 may adjust at least one of the scanning depth of the unfocused ultrasonic wave, the scanning density of the unfocused ultrasonic wave, and the emission frequency point of the unfocused ultrasonic wave to a second preset threshold according to the blood flow type of the target blood flow, where the second preset threshold corresponds to the blood flow type of the target blood flow. For example, if the target blood flow is a large blood vessel, at least one of the scanning depth of the unfocused ultrasonic wave, the scanning density of the unfocused ultrasonic wave, and the emission frequency point of the unfocused ultrasonic wave may be adjusted to a second preset threshold based on the large blood vessel, that is, the setting of the second preset threshold may be set by the user according to previous ultrasound scanning experience to a value most suitable for the blood vessel type, for example, the value may be the value with the best imaging effect or the value with the richest data, which is not limited specifically. In addition, the second preset threshold corresponds to a target doppler parameter, for example, if the target parameter is a scanning depth of the unfocused ultrasonic wave, the second preset threshold is a numerical value corresponding to the scanning depth of the unfocused ultrasonic wave, the target doppler parameter is a scanning density of the unfocused ultrasonic wave and a transmitting frequency point of the unfocused ultrasonic wave, and the second preset threshold is a threshold corresponding to the scanning density of the unfocused ultrasonic wave and the transmitting frequency point of the unfocused ultrasonic wave, respectively.
It should be noted that the emission frequency points of the unfocused ultrasonic wave include at least one of the emission frequency points of the B-type image, the emission frequency points of the C-type image, and the emission frequency points of the PW-type image.
3. When the target doppler parameters include parameters of the color doppler sample box and/or parameters of the pulse doppler sample line, the processor 105 may adjust the parameters of the color doppler sample box and/or parameters of the pulse doppler sample line, the preset condition and the target blood flow according to the target blood flow. For example, the target blood flow is a large blood vessel, the preset condition may be set according to the blood flow type of the large blood vessel (e.g., the doppler coverage area of the large blood vessel, the position of the large blood vessel on the ultrasound blood flow image, and the display form of the large blood vessel on the ultrasound blood flow image), for example, the parameter of the color doppler sampling frame is adjusted, the preset condition should be set to correspond to the parameter of the color doppler sampling frame and the doppler data information of the target blood flow, respectively, for example, the adjusted parameter is the area and the position of the color doppler sampling frame, the preset condition is that the area of the color doppler sampling frame is to completely cover the doppler coverage area of the target blood flow, for example, the area of the color doppler sampling frame is larger than the doppler coverage area of the target blood flow.
It should be noted that the parameters of the color doppler sample frame include an area of the color doppler sample frame, a position of the color doppler sample frame, and a deflection angle of the color doppler sample frame, and the parameters of the pulse doppler sample line include a deflection angle of the pulse doppler sample line, a position of a sample volume of the pulse doppler sample line, a width of the sample volume, and a blood flow direction schematic line angle in the sample volume.
In practical applications, the target doppler parameter can be adjusted by combining the three methods, which are described below with reference to fig. 3 and 4:

The unreal optimization parameters in fig. 4 may further include, for example, adjustment of the transmission frequency points of the B-type image, adjustment of the transmission frequency points of the C-type image, and the like.
