Detailed Description
The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings in the specification of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Generally, a medical ultrasonic diagnostic apparatus includes an ultrasonic main unit, a probe connected to the ultrasonic main unit, a display unit, and an input unit. The ultrasonic host generates an ultrasonic image according to the target volume ultrasonic echo signal received by the probe, and displays the ultrasonic image on a display interface of the display unit, and simultaneously displays other processing, assistance, prompt and other information related to the ultrasonic image on the display interface. The input unit is used for an operator to transmit an operation command to the ultrasonic host computer so as to improve the image performance or meet the requirement of the operator.
The present embodiment provides a parameter adjustment method suitable for an ultrasonic diagnostic apparatus, which is used for the ultrasonic diagnostic apparatus shown in fig. 1, and the method comprises the following steps:
s11 presetting: the corresponding relation between the moving direction input by the input unit and the parameter change of the object to be adjusted 11;
the moving direction refers to directional information commands, such as up, down, left, right, or any direction.
The input unit is preferably a trackball.
The object to be adjusted 11 refers to an object whose parameters can be adjusted, such as an ultrasound real-time image, a frozen image, a panoramic image, a body mark probe identification, and the like.
The parameters are not limited here, and depend on the characteristics of the object to be adjusted, such as the width, deflection, depth, extended imaging, focusing, gain, rotation of the ultrasound image in the linear array probe mode; angle, depth, extended imaging, focusing, gain and rotation of the ultrasonic image in the convex array probe mode; rotating the wide view image; and (4) rotating the body mark probe mark.
The parameter change refers to parameter increase, decrease, rise, fall, rotation by different angles, and the like.
The corresponding relation is set according to different changes of the same parameter or different changes of different parameters corresponding to different moving directions, so that the trackball can simultaneously adjust the changes of one or more parameters.
For example, taking the adjustment of the ultrasound image in the line array probe mode as an example, a parameter a of the adjustable ultrasound image is set, where the parameter a is a width, and the corresponding relationship is: when information moving upward is input, the width increases, and when information moving downward is input, the width decreases; and/or the width increases when information moving to the right is input and decreases when information moving to the left is input.
Or for example, the adjustment object is set as an ultrasound image in a convex probe mode, two parameters b and c of the ultrasound image can be adjusted simultaneously, where the parameter b is an angle and the parameter c is a depth, and the corresponding relationship is as follows: the angle increases when information moving to the right is input, the angle decreases when information moving to the left is input, and the depth increases when information moving to the up is input and the depth decreases when information moving to the down is input; or when inputting the information moving towards the horizontal line clockwise and anticlockwise lambda angle, the parameter b becomes larger or smaller; and the parameter c becomes larger or smaller when information moving clockwise and counterclockwise (90-lambda) angles to the vertical line is inputted, wherein 90 DEG & gtlambda & gt 0 deg.
Or for example, setting the adjustment object as a wide-scene image, and setting the parameter as the rotation angle thereof, wherein the corresponding relationship is as follows: inputting information moving towards the first quadrant direction, and rotating the wide view image towards the upper right; inputting the angle moving direction of the second quadrant, and rotating the wide view image to the upper left; inputting the angle moving direction of the third quadrant, and rotating the wide view image to the lower left; and inputting the angle moving direction of the fourth quadrant, and rotating the wide view image to the lower right.
As an alternative embodiment, the input unit is divided into functional areas, and information is inputted in different areas, so that different parameter changes of the object 11 to be adjusted can be adjusted, for example, as shown in FIG. 2, the parameters d extended imaging and e-focusing of the ultrasound image are set to be adjusted, and the extended imaging is turned off when information moving leftward is inputted in the left side of the central vertical line of the input unit, the central horizontal line is α degrees clockwise or counterclockwise, the extended imaging is turned on when information moving rightward is inputted in the right side of the central vertical line, the central horizontal line is α degrees clockwise or counterclockwise, the focus area is decreased/the focus position is moved upward when information moving upward is inputted in the angle above the central horizontal line, the center vertical line is 3526 degrees clockwise or counterclockwise (90- α degrees), and the focus area is increased/the focus position is moved downward when information moving downward is inputted below the central horizontal line, wherein 90 DEG α is 0 deg.
S12 selecting the object 11 to be adjusted on the display interface 10;
the display interface 10 generally refers to an image area displayed by the display unit of the ultrasound apparatus.
The operator can select the object 11 to be adjusted on the display interface 10 under a certain function by means of a track ball, a keyboard, function keys and the like.
S13, adjusting at least one parameter of the object to be adjusted according to the moving direction input by the input unit;
according to the setting of different parameters corresponding to different moving directions, the trackball can simultaneously adjust the change of one or more parameters, and is simple and convenient to operate, so that the trackball can be suitable for various occasions used by doctors, particularly sterile operating environments.

step S13 further includes calculating the variation of the corresponding parameter according to the movement amount and the unit variation movement amount, and adjusting the parameter value.
Further, the method comprises a step S14 of displaying a parameter value of the object to be adjusted 11.
The parameter adjusting method provided by the embodiment can adjust a plurality of parameters of the object to be adjusted simultaneously, is simple and convenient to operate, has excellent operation experience, and greatly reduces the operation pressure of a doctor through simple and convenient operation of ultrasonic equipment particularly under the condition that the doctor holds the ultrasonic probe with one hand and holds a surgical instrument with the other hand.
