[0048] In the embodiment, a speed regulation method of an angiography device is provided, Figure 2 The flowchart of the speed regulation method of the angiography device in the embodiment is shown in FIG. 2, and the flow includes the following steps: Figure 2

[0049] In step S210, in response to a control operation on the hand brake, the movement speed of the angiography device is controlled to change following the change of the control operation on the hand brake.

[0050] ​In the embodiment, the device body of the angiography device is connected with a hand brake for controlling the movement of the device. It should be noted that the device speed regulation function can be integrated into the existing hand brake of the angiography device such as the exposure hand brake, and the existing hand brake is usually provided with device functions such as exposure and fluoroscopy, so as to avoid adding additional control devices and facilitate operation.

[0051] Specifically, in response to the control operation on the hand brake, the movement speed of the angiography device is controlled to change with the change of the control operation on the hand brake. It should be noted that the control operation on the hand brake can be performed by the user or automatically performed by the device, and the control operation on the hand brake is determined by the preset operation method corresponding to the hand brake, for example, in the case that the control element is installed on the hand brake, the control operation can be adjusting the moving position of the control element, or in the case that the touch screen is provided on the hand brake, the icon for adjusting the speed in the touch screen is controlled. The embodiment does not limit the operation method of the hand brake.

[0052] When the user manually performs the control operation on the hand brake or the device automatically generates the control instruction on the hand brake, in response to the control operation on the hand brake, the corresponding control signal is generated and transmitted to the motor or other driving device of the angiography device, the movement speed of the driving device is changed according to the control signal, and then the movement speed of the device is changed. Wherein, the hand brake is operated according to the actual device scanning requirement, for example, the real-time flow speed of the contrast agent in the target blood vessel is taken as the basis, or the hand brake is operated according to the historical experience information related to the current scanning task.

[0053] In the process of using the angiography device for examination, the device needs to move to different positions, and the device movement speed needs to be adapted to the flow speed of the contrast agent in the blood vessel, but the hand brake currently applied to the angiography device only has functions such as exposure and fluoroscopy, and cannot accurately control the device movement speed.

[0054] Compared with the prior art, the angiography device of the present application is provided with a hand brake, and the movement speed of the angiography device is controlled to change with the change of the control operation on the hand brake in response to the control operation on the hand brake, so as to trigger the speed regulation function, control the movement speed change of the angiography device corresponding to the control operation on the hand brake, solve the problem of unable to accurately control the device movement speed, and realize the accurate control of the device movement speed.

[0055] In some embodiments, the hand brake includes a control element; and the step S210 of controlling the movement speed of the angiography device to change with the change of the control operation on the hand brake in response to the control operation on the hand brake includes the following steps:

[0056] In response to the position moving operation on the control element, the motion speed of the angiography device changes following the change of the moving position of the control element.

[0057] Specifically, the hand brake is provided with a control element, which includes but is not limited to a control button, a control knob and a control rocker. Exemplarily, when the control element is a control button, the position moving operation on the control element is to change the stroke position of the control button; when the control element is a control knob, the position moving operation on the control element is to change the rotation angle of the control knob; when the control element is a control rocker, the operation direction of the control rocker is preset, such as setting the forward pushing of the control rocker as the operation direction for adjusting the speed, and the like, and at this time, the position moving operation is to change the forward pushing amplitude of the control rocker.

[0058] When the user manually performs the position moving operation on the control element or the device automatically performs the position moving operation on the control element, the moving position of the control element changes, and the moving position change can be a continuous position change or a change according to a preset gear. According to the change of the moving position, a corresponding control signal is generated, which is transmitted to the motor or other driving device of the angiography device, and the motion speed of the driving device is changed according to the control signal, so as to correspondingly change the motion speed of the device.

[0059] It should be noted that in the case of integrating the device speed control function into the existing hand brake, in addition to the control element for device speed control, other functional elements are provided on the hand brake, such as exposure buttons, perspective buttons, multifunctional buttons and the like, so as to facilitate different operations.

[0060] Through the embodiment, the control element is provided on the hand brake, in response to the position moving operation on the control element, the motion speed of the angiography device changes following the change of the moving position of the control element, so as to accurately operate the hand brake and improve the accuracy of the device speed control.

[0061] In some embodiments, the hand brake further includes a potentiometer; the control element is electrically connected to the potentiometer; and in response to the control operation on the hand brake in step S210, the motion speed of the angiography device changes following the change of the control operation on the hand brake, including the following steps:

[0062] In response to the position moving operation on the control element, the voltage value of the potentiometer changes following the change of the moving position of the control element;

[0063] According to the change of the voltage value of the potentiometer, the motion speed of the angiography device changes following the change of the voltage value of the potentiometer.

[0064] In the embodiment, the hand brake is provided with a potentiometer, and the control element is electrically connected with the potentiometer. When the user manually performs a position moving operation on the control element or the equipment automatically performs a position moving operation on the control element, the moving position of the control element is changed, and at this time, the voltage value of the potentiometer changes along with the change of the moving position. For example, in the case where the control element is a control button, the stroke position of the control button is set corresponding to the voltage value of the potentiometer, the initial position of the control button corresponds to the initial voltage value of the potentiometer (as shown in Figure 3 , and the maximum position of the control button corresponds to the maximum voltage value of the potentiometer (as shown in Figure 4 ), that is, along with the movement of the control button from the initial position to the maximum position, the potentiometer also changes from the initial voltage value to the maximum voltage value.

[0065] Further, according to the change of the voltage value of the potentiometer, a corresponding voltage signal is output to the motor or other driving device of the angiography equipment, and the movement speed of the driving device is changed according to the size of the voltage signal, and the movement speed of the equipment is changed.

[0066] It should be noted that, in addition to the above-mentioned potentiometer, an electronic device such as a programmable logic controller can be installed in the hand brake, so that the output signal of the device changes along with the change of the moving position of the control element, and the movement speed of the angiography equipment is controlled according to the output signal.

[0067] Through the embodiment, in response to the position moving operation on the control element, the voltage value of the potentiometer changes along with the change of the moving position of the control element, and according to the change of the voltage value of the potentiometer, the movement speed of the angiography equipment changes along with the change of the voltage value of the potentiometer, so as to realize the precise control of the equipment speed by using the change of the voltage signal.

[0068] In some of the embodiments, the above-mentioned speed regulation method of the angiography equipment further comprises the following steps:

[0069] previously setting a target voltage value for triggering the angiography equipment to start moving;

[0070] determining a first moving position of the control element corresponding to the target voltage value;

[0071] when it is detected that the moving position of the control element reaches the first moving position, controlling the angiography equipment to start moving.

[0072] Specifically, an effective region of the potentiometer is preset, the effective region is used to indicate a target voltage value of the potentiometer, the target voltage value refers to a potentiometer voltage value used to trigger the angiography device to start moving, since the moving position of the control element corresponds to the voltage value of the potentiometer, the moving position of the control element corresponding to the target voltage value, i.e., the first moving position, is determined, and when it is detected that the moving position of the control element reaches the first moving position, the angiography device is controlled to start moving.

[0073] Exemplarily, the minimum voltage value of the potentiometer is taken as the potentiometer voltage value used to trigger the angiography device to start moving, and when the moving position of the control element changes from the initial position to a position 2 millimeters away from the initial position, the potentiometer reaches the minimum voltage value, and thus when it is detected that the moving position of the control element reaches the position 2 millimeters away from the initial position, the angiography device is controlled to start moving.

[0074] Through the embodiment, the target voltage value used to trigger the angiography device to start moving is preset, and the first moving position of the control element corresponding to the target voltage value is determined, and when it is detected that the moving position of the control element reaches the first moving position, the angiography device is controlled to start moving, thereby preventing the hand brake speed regulation function from being triggered by mistake and improving the stability of the control device.

[0075] In some of the embodiments, the speed regulation method of the angiography device further includes the following steps:

[0076] The voltage value of the potentiometer is compared with a preset voltage threshold value;

[0077] According to the comparison result, it is determined whether the hand brake is disconnected.

[0078] Specifically, when the disconnection of the hand brake is detected, the current voltage value of the potentiometer is obtained, the voltage value of the potentiometer is compared with the preset voltage threshold value, it is determined whether the hand brake is disconnected according to the comparison result, and the disconnection detection result is fed back to the user. For example, in the case where the hand brake is disconnected, a pop-up window on the device screen is used to prompt the user that the hand brake is disconnected and the speed regulation control function of the current hand brake is invalid, and the user is prompted to replace the hand brake.

[0079] If the detected current voltage value is close to 0 and less than a preset first disconnection detection determination value, it is determined that the signal cable or the positive power supply cable of the hand brake is disconnected; and if the detected current voltage value is close to the power supply voltage value and less than a preset second disconnection detection determination value, it is determined that the negative power supply cable of the hand brake is disconnected.

[0080] By comparing the voltage value of the potentiometer with the preset voltage threshold value, and judging whether the hand brake is broken according to the comparison result, the hand brake can be detected in time, the speed control function of the hand brake can be prevented from being continuously invalid or in a misoperation state, and the device performance can be improved.

[0081] In some embodiments, the speed regulation method of the above angiography device further includes the following steps:

[0082] When the control element is in different moving positions, reference voltage values of the potentiometer are obtained;

[0083] According to the reference voltage values, the correspondence between the moving positions of the control element and the voltage values of the potentiometer is corrected.

[0084] Specifically, when the moving position of the control element is in the initial position, a first reference voltage value of the potentiometer is obtained, and the first reference voltage value is taken as the zero voltage value of the hand brake. When the first reference voltage value of the potentiometer is obtained, voltage values are sampled within a preset time period, and the second largest voltage value among the sampled voltage values is recorded as the first reference voltage value.

[0085] Further, the moving position of the control element is adjusted to the maximum position, a second reference voltage value of the potentiometer is collected, and the second reference voltage value is taken as the terminal voltage value of the hand brake. When the second reference voltage value of the current potentiometer is collected, voltage values are sampled within a preset time period, and the minimum voltage value among the sampled voltage values is recorded as the second reference voltage value.

[0086] It should be noted that in the embodiment, the first reference voltage value and the second reference voltage value of the potentiometer can be obtained by clicking the preset correction button to trigger the sampling voltage value when the control element is in different moving positions, and the zero voltage value and the terminal voltage value of the hand brake are respectively corrected by using the first reference voltage value and the second reference voltage value, so as to correct the correspondence between the moving positions of the control element and the voltage values of the potentiometer. In addition, if the zero voltage value and the terminal voltage value of the hand brake are not within the preset allowable range after correction, it indicates that the current hand brake is not calibrated, and the user can be informed that the hand brake cannot be calibrated by using a pop-up window, voice prompt, etc.

[0087] By the embodiment, when the control element is in different moving positions, the reference voltage values of the potentiometer are obtained, and the correspondence between the moving positions of the control element and the voltage values of the potentiometer is corrected according to the reference voltage values, so as to eliminate the accumulated error of the hand brake caused by long-term use and improve the accuracy of the speed regulation function of the hand brake.

[0088] In some embodiments, before the motion speed of the angiography device is controlled to change in response to the control operation on the hand brake, the method further comprises the following steps:

[0089] acquiring a flow speed of the contrast agent in the target blood vessel;

[0090] generating a control instruction for the hand brake according to the flow speed of the contrast agent;

[0091] performing a control operation on the hand brake as instructed by the control instruction.

[0092] Specifically, during the scanning of the device, the flow speed of the contrast agent in the target blood vessel is detected in real time, and a corresponding control instruction is generated according to the flow speed of the contrast agent, the control instruction being an instruction for the hand brake. A control operation on the hand brake as instructed by the control instruction is performed, and the motion speed of the angiography device is controlled to change in response to the control operation on the hand brake.

[0093] It should be noted that in this embodiment, the control operation on the hand brake is automatically performed by the device, that is, the hand brake is automatically operated according to the generated control instruction.

[0094] Through this embodiment, the flow speed of the contrast agent in the target blood vessel is acquired, a control instruction for the hand brake is generated according to the flow speed of the contrast agent, and a control operation on the hand brake as instructed by the control instruction is performed. The motion speed of the angiography device is controlled to change in response to the control operation on the hand brake, so as to follow the flow speed of the contrast agent in the blood vessel to adjust the speed of the device, thereby improving the quality of the images collected by the device.

[0095] In some embodiments, acquiring the flow speed of the contrast agent in the target blood vessel comprises the following steps:

[0096] acquiring images of the target blood vessel through which the contrast agent flows at a preset time interval to obtain a plurality of angiography images;

[0097] determining a position of arrival of the contrast agent in each angiography image;

[0098] determining the flow speed of the contrast agent according to the positions of arrival and the preset time interval.

[0099] Specifically, a sequence of continuous angiography images is acquired at a preset time interval, the sequence of angiography images containing a plurality of angiography images, and each angiography image containing real-time flow information of the contrast agent in the target blood vessel.

[0100] Further, in each angiography image, the contrast agent arrival position corresponding to each angiography image is obtained by taking the same anatomical landmark as the reference point of the contrast agent position, the distance information of the contrast agent arrival positions in adjacent angiography images is calculated according to the acquisition time of each angiography image, and the ratio of each distance information to the time interval is calculated, and the average of each ratio is taken as the flow velocity of the contrast agent, or the median of each ratio is selected as the flow velocity of the contrast agent.

[0101] Through the embodiment, the target blood vessel through which the contrast agent flows is imaged based on the preset time interval to obtain a plurality of angiography images, the arrival position of the contrast agent in each angiography image is determined, and the flow velocity of the contrast agent is determined according to the arrival positions and the preset time interval, so as to accurately calculate the flow velocity of the contrast agent, which helps to improve the accuracy of the speed control of the device.

[0102] The embodiment will be described and illustrated below through preferred embodiments.

[0103] Figure 5 is a flow chart of the speed control method of the angiography device of the preferred embodiment, as shown in the figure, the speed control method of the angiography device comprises the following steps: Figure 5

[0104] Step S510, in response to the position moving operation of the control button, the voltage value of the potentiometer changes with the change of the moving position of the control button;

[0105] Step S520, according to the change of the voltage value of the potentiometer, the movement speed of the angiography device changes with the change of the voltage value of the potentiometer.

[0106] Through the embodiment, in response to the position moving operation of the control button, the voltage value of the potentiometer changes with the change of the moving position of the control button, and according to the change of the voltage value of the potentiometer, the movement speed of the angiography device changes with the change of the voltage value of the potentiometer, solving the problem that the device movement speed cannot be accurately controlled, and realizing accurate control of the device movement speed.
