The patient detection unit 190 is communicatively connected to the processor 130, and the patient detection unit 190 is configured to detect a body temperature of the patient and transmit the body temperature of the patient to the processor 130. The processor 130 is configured to control the heating component 184 to heat the couplant in the plastic cavity 181 according to the body temperature, so that the temperature of the couplant in the plastic cavity 181 is equal to the body temperature of the patient.
By adopting the scheme, the couplant with the temperature equal to the body temperature of the patient is smeared on the patient, the patient feels good, the patient does not feel cold to generate contraction of muscles and skin tissues, so that the B ultrasonic probe 110 can scan an accurate B ultrasonic image of a part to be detected, the B ultrasonic image can accurately reflect the condition of the part to be detected, and meanwhile, the couplant is automatically smeared, so that the accuracy and the convenience of B ultrasonic detection are improved.

Specifically, when the processor 130 determines that the temperature of the couplant in the plastic cavity 181 is equal to the body temperature of the patient, an opening signal is sent to the solenoid valve 183 to control the solenoid valve 183 to open, and then the first opening 182 is opened, so that the couplant flows out from the plastic cavity 181, and can be smeared on a part to be detected.
Wherein the patient detection part 190 includes an infrared temperature sensor and a camera. The infrared temperature sensor and the camera are both connected to the processor 130.

The camera is used for shooting the part coated with the couplant to obtain a couplant image, and the couplant image is sent to the processor 130. The processor 130 is configured to determine whether the applied couplant is less than a set amount according to the couplant image, and if it is determined that the applied couplant is not less than the set amount, send a closing message to the electromagnetic valve 183 to control the electromagnetic valve 183 to close, and further control the first opening 182 to close, so as to control the couplant in the plastic cavity 181 not to flow out. If the applied couplant is determined to be not less than the set amount, the electromagnetic valve 183 is continuously opened, the first opening 182 is further controlled to be continuously opened, so that the couplant in the plastic cavity 181 flows out, further more couplant is continuously applied, and the condition that the B-ultrasonic image scanned by the B-ultrasonic probe can accurately reflect the part to be inspected is ensured.

and counting a color histogram of the couplant image, comparing the color histogram of the couplant image with a standard couplant image histogram, if the variance between the color histogram of the couplant image and the standard couplant image histogram is less than 10, determining that the applied couplant is less than the set amount, otherwise, determining that the applied couplant is not more than the set amount.
Optionally, a second opening 185 is further formed in the couplant storage portion 180, and the second opening 185 is used for injecting the couplant into the plastic cavity 181.
Optionally, the heating B-mode ultrasound scanner 100 further comprises a handle 140; the handle 140 includes a hollow cavity 141;
an internal thread is arranged on the inner wall of one end of the hollow cavity 141, an external thread is arranged on the control part 150, and the control part 150 is movably arranged in the hollow cavity 141 through the matching between the external thread and the internal thread so as to drive the ultrasonic B probe 110 arranged at the end of the hollow cavity 141 far away from the internal thread to move along the axial direction of the hollow cavity 141.

The patient detection unit 190 is provided on the second buckle.
Wherein, the plastic cavity 181 has elasticity, and if the couplant in the plastic cavity 181 is reduced, the plastic cavity 181 is reduced accordingly, so as to extrude the couplant in the plastic cavity 181 from the first opening 182.
In order to uniformly apply the couplant to the portion to be inspected, two parallel rows of brushes are disposed on the first opening 181. The two rows of parallel brushes are used for uniformly coating the couplant extruded out from the plastic cavity 181 on the part of the human body to be detected.
In order to detect the temperature of the couplant in the plastic cavity 181, a temperature sensor is further disposed in the plastic cavity 181, and the temperature sensor is configured to detect the temperature of the couplant in the plastic cavity 181, and send a temperature signal of the couplant to the processor 130 when heating of the couplant is stopped. The processor 130 judges whether the temperature of the couplant is equal to the body temperature of the patient or not according to the temperature signal, and controls the heating part 184 to continue heating the couplant in the plastic cavity 181 if the temperature of the couplant is less than the body temperature of the patient until the temperature of the couplant is equal to the body temperature of the patient or not.

When the temperature of the couplant in the plastic cavity 181 is equal to the body temperature, the processor 181 controls the electromagnetic valve 183 to open so as to control the first opening 182 to open, and the plastic cavity 181 extrudes the couplant out of the first opening 182. And then smearing the couplant on the part to be detected through two rows of parallel brushes, and scanning the part to be detected through a B ultrasonic probe to obtain a B ultrasonic image. Therefore, the patient feels good, and the accuracy and the convenience of B ultrasonic detection are improved.
In the current B ultrasonic detection process, after the couplant is smeared on a human body, the couplant is wiped off by a paper towel, if the smeared couplant is too much, the paper towel is wasted, and on the other hand, the couplant cannot be recycled, so that the resource waste is caused.
In order to solve the above problem, the heating B-mode ultrasonic scanner 100 according to the embodiment of the present invention further includes a couplant recovery unit 120, and the couplant recovery unit 120 is electrically connected to the processor 130. The processor 130 is configured to determine whether the quality of the B-mode ultrasound image meets a standard, and if so, send a recovery signal to the couplant recovery unit 120, so that the couplant recovery unit 120 recovers the couplant at the position of the human body corresponding to the B-mode ultrasound image. Therefore, the coupling agent is recycled, and resources are saved.
Alternatively, the processors may be dragon core 3A3000/383000, Intel core i5-9300H, Intel core i5-9400H, Intel core i79750H, Intel core i7-9850H, Intel core i9-9880H, and Intel core i9-9980 HK.
In order to improve the accuracy of the processor 130 in determining whether the quality of the B-mode ultrasound image meets the standard, the specific way of determining whether the quality of the B-mode ultrasound image meets the standard by the processor 130 is as follows: the processor 130 transforms each pixel point in the B-mode ultrasound image to obtain a transformed image. If the variance between the color histogram of the B-mode ultrasound image and the color histogram of the transformed image is smaller than the set value, the processor 130 determines that the quality of the B-mode ultrasound image meets the standard.
Specifically, the processor 130 calculates the variance between the color histogram of the B-mode ultrasound image and the color histogram of the transformed image on the same abscissa, and if the variance is smaller than a set value, the processor 130 determines that the quality of the B-mode ultrasound image meets the standard. For example, the histogram vector of the color histogram of the B-mode ultrasound image is X ═ (20,30,24,50), the histogram vector of the color histogram of the converted image is Y ═ (25,20,24,30), and the setting value Z is 100.
Variance (variance)

Wherein x isi,yiThe values of the elements in the histogram vector X and Y, respectively, n is the number of the elements in the histogram vector X and Y, in this example, n is 4, X1＝20，x2＝30，x3＝24，x4For 50, same reason, yiThe values of i-1, 2,3 and 4 are 25,20,24 and 30 respectively. From this, it can be seen that σ2If (X, Y) > Z, the quality of the B-ultrasonic image can be determined to be not up to the standard. For example, X ═ 20,30,24,50 and Y ═ 21,20,24,45), then
Figure BDA0002380315510000052
The quality of the B-mode ultrasound image can be determined to be up to standard.
The processor 130 transforms each pixel point in the B-mode ultrasound image to obtain a transformed image, specifically: firstly, the processor takes a first pixel point (i, j) in the B-mode ultrasonic image as a reference point, maps the reference point (i, j) to a pixel point (i ', j') in an empty transformation image, and the calculation formula for mapping the reference point (i, j) to the pixel point (i ', j') is as follows:
Figure BDA0002380315510000053
wherein, (i, j) represents the position of the pixel point in the ith row and the jth column in the B-mode ultrasound image, (i ', j') represents the position of the pixel point corresponding to the pixel point (i, j) in the transformed image, i is 0,1,2,3128And excluding numbers that are multiples of N; d ranges from 1 to 2128Integer of between, | i-ai2/2+ d mod N | represents i-ai2Absolute value of/2 + d mod N.
Secondly, the processor assigns the pixel value I (I, j) of the reference point (I, j) to the pixel point (I ', j') to obtain a pixel value p (I ', j') of the pixel point (I ', j'), wherein p (I ', j') is equal to I (I, j).
As an alternative embodiment, before mapping the reference point (i, j) to the pixel point (i ', j') in the empty transformed image, the method further includes:
the processor judges whether (i ', j') in the transformed image is mapped, if so, the reference point (i, j) is mapped to a pixel point (i ', j' +1) in the empty transformed image, otherwise, the reference point (i, j) is mapped to a pixel point (i ', j') in the empty transformed image.
Optionally, before mapping the reference point (i, j) to the pixel point (i ', j' +1) in the empty transformed image, the method further includes:
the processor judges whether (i ', j' +1) in the transformed image is mapped, if so, the reference point (i, j) is mapped to a pixel point (i '+1, j') in the empty transformed image, otherwise, the reference point (i, j) is mapped to a pixel point (i ', j' +1) in the empty transformed image.
Similarly, before mapping the reference point (i, j) to the pixel point (i '+1, j') in the empty transformed image, the method further includes:
the processor judges whether (i '+1, j') in the transformed image is mapped, if so, the reference point (i, j) is mapped to a pixel point (i '+1, j' +1) in the empty transformed image, otherwise, the reference point (i, j) is mapped to a pixel point (i '+1, j') in the empty transformed image.
And the analogy is repeated until the point which is closest to the (i ', j') in the transformed image is found, the point is called a target point, and the reference point (i, j) is mapped to the target point in the empty transformed image. And assigning the pixel value I (I, j) of the reference point (I, j) to the target point to obtain the pixel value of the target.
Therefore, the stability of converting the B-ultrasonic image into the converted image is ensured, the fidelity of the converted image to the B-ultrasonic image is improved, and the accuracy of judging whether the quality of the B-ultrasonic image reaches the standard is improved.
Optionally, in order to realize automatic recovery of the couplant by the couplant recovery part 120, the couplant recovery part 120 includes an elastic recovery bag 121 and a vacuum generation part 122. The vacuum generating unit 122 is connected to the processor 130, and the processor 130 is configured to control the vacuum generating unit 122 to generate vacuum, so that the elastic recovery bag 121 is in a vacuum state, and the elastic recovery bag 121 generates negative pressure to suck the couplant.
The elastic recovery bag 121 and a vacuum generating portion 122 are communicated through an air opening which allows only air (vacuum) to enter and exit, and other substances such as a coupling agent cannot enter and exit. In the present invention, a plurality of layers of gauze are disposed in the air opening to ensure air (vacuum) communication between the elastic recovery bag 121 and the vacuum generating portion 122, so as to prevent the coupling agent in the elastic recovery bag 121 from entering the vacuum generating portion 122. Specifically, the elastic recovery bag 121 is provided with a third opening 1211 and a fourth opening 1212, and the third opening 1211 is used for sucking the couplant.
The fourth opening 1212 is connected to the vacuum nozzle 1221 of the vacuum generating portion 122, and the vacuum generating portion 122 is configured to evacuate the elastic recovery bag 121 through the fourth opening 1212 to form a vacuum space, so as to reduce the pressure inside the elastic recovery bag 121 to be less than the atmospheric pressure, so that the elastic recovery bag 121 can suck the coupling agent on the position of the human body corresponding to the B-ultrasonic image through the third opening 1211. That is, the vacuum nozzle 1221 and the fourth opening 1212 constitute an air opening. A plurality of layers of gauze are disposed between the vacuum nozzle 1221 and the fourth opening 1212.
The vacuum generator 121 may be a vacuum generator, such as a schmalz vacuum generator.
When the ultrasonic couplant bag is used, the processor 130 sends a control signal to the vacuum generator to control the vacuum generator to work, so that the elastic recovery bag 121 is pumped into a vacuum space, and when the pressure in the elastic recovery bag 121 is lower than the atmospheric pressure, the couplant on the human body position corresponding to the B ultrasonic image is squeezed into the elastic recovery bag 121 under the action of the atmospheric pressure, so that the elastic recovery bag 121 sucks the couplant on the human body position corresponding to the B ultrasonic image.
