Image Adjustment Method of Ultrasonic Imaging Device {Diplay Calibration Method for Ultrasonic Aparratus}

The present invention relates to an image adjusting method of an ultrasonic imaging apparatus. In the method of adjusting an image in an ultrasonic imaging apparatus, a user inputs three parameters of brightness, contrast, and frame rate. Adjust the input point 20 within a triangular shape 10 whose vertices 11, contrast 12, and frame rate vertices 13 are shown as vertices. Inputting (S1), each of the brightness vertices 11, the contrast vertex 12 and the frame rate vertex of the input point 20 and the triangular shape 10; Calculating the respective distances between (13) (S2) and the brightness vertices (11), contrast vertices (12) and frames of the input point (10) and the triangular shape (10). Frame rate using the distance between the vertices 13 After determining the three parameter values of brightness, contrast and frame rate, the corresponding gain, depth, frequency, scanline number, and number And a step (S3, S4, S5) of determining a TGC (Time Gain Compensation) and a dynamic range to adjust the screen.

In order to adjust the image in existing commercial ultrasonic devices, gain, depth, frequency, number of scanlines, time gain compensation, and dynamic range Numerous parameters must be set individually via the control knobs.

However, this setting method is very inconvenient to adjust each parameter independently, and in case of adjusting one parameter and then adjusting other parameters, the change of the image to be expressed by the association between the parameters in advance There is a problem in that the user's accessibility is very low because it requires more than expert level background knowledge such as predicting and adjusting each parameter.

In order to solve the above-described problems of the present invention, a gain, a depth, a frequency, a number of scanlines, a time gain compensation, and a dynamic range By integrating numerous parameters, such as range, into three parameter values of brightness, contrast, and frame rate, the user can easily change the three parameters by adjusting the position of the input point. An object of the present invention is to provide an image adjusting method of an ultrasonic imaging apparatus that observes a change in a screen and adjusts the image easily and intuitively.

In order to achieve the above object, the image adjusting method of the ultrasonic imaging apparatus of the present invention is a method of adjusting an image in the ultrasonic imaging apparatus, wherein the user has three kinds of brightness, contrast, and frame rate. The parameters may be entered within a triangular shape 10 whose vertices are the brightness vertices 11, the contrast vertices 12, and the frame rate vertices 13 displayed on the screen. Step S1 of inputting, the brightness vertices 11, the contrast vertices 12, and the frame refresh rate of the input points 20 and the triangular shape 10. calculating the respective distances between the vertices 13 (S2) and the brightness vertices 11 and contrast vertices of the input point 10 and the triangular shape 10; 12) and the respective distance between the frame rate vertex 13 Three parameters of brightness, contrast, and frame rate are determined, and then the corresponding gain, depth, frequency, and scanline are used. Steps S3, S4, and S5 for determining the number, time gain compensation (TGC) and dynamic range (Dynamic Range), and adjusting the screen are characterized.

In addition, the step S1 of adjusting and inputting the input point 20 in the triangular shape 10 may include the brightness vertex 11, the contrast vertex 12, and the frame rate. It is characterized in that it further comprises the step of inputting the position of the vertex 13 by the user's adjustment, respectively.

In addition, a method of inputting the positions of the input point 20 and the brightness vertex 11, the contrast vertex 12, and the frame rate vertex 13 by user adjustment, respectively The touch screen may be input using any one of a touch screen, a mouse, a trackball, and an adjustment knob.

According to the present invention, instead of individually setting a number of parameters such as gain, depth, frequency, number of scanlines, and TGC in order to express an image of a desired image quality in an ultrasonic imaging apparatus, contrasts that can be viewed on a TV or a PC monitor, etc. The three parameter values of brightness, contrast and frame rate can be directly observed by changing the quality of the display screen and can be easily adjusted by interlocking with each other in an intuitive and user-friendly way. This has the advantage of greatly improving and greatly improving the accessibility of the user.

Hereinafter, an image adjusting method of an ultrasound imaging apparatus according to an exemplary embodiment will be described in detail with reference to the accompanying drawings. First, in the drawings, the same components or parts are to be noted that as indicated by the same reference numerals as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

In the image adjusting method of the ultrasonic imaging apparatus of the present invention, as shown in the flow chart of FIG. 1, the user adjusts three parameters of brightness, contrast, and frame rate. As shown in the figure, an input point within a triangular shape 10 having a brightness vertex 11, a contrast vertex 12, and a frame rate vertex 13 as a vertex. The step S1 is started by freely adjusting 20) up, down, left, and right. In this case, as the method of inputting the input point 20, it is possible to input using various input means such as a touch screen, a mouse, a trackball or an adjustment knob.

Next, between each of the brightness vertices 11, the contrast vertex 12 and the frame rate vertex 13 of the input point 20 and the triangular shape 10. A step S2 of calculating each distance is performed.

Each calculated between the input point 20 and the brightness vertex 11, contrast vertex 12 and frame rate vertex 13 of the triangular shape 10 thus calculated The distance is used to determine the three parameter values of brightness, contrast and frame rate. In FIG. 2, the numbers 70, 40, 60 shown in parentheses next to each of the brightness vertices 11, contrast vertices 12 and frame rate vertices 13 are: According to an embodiment of the present invention, when the input point 20 is located at the position shown in FIG. 2, the input point 20, the brightness vertex 11, and a contrast vertex ( 12) and three frame values, each of brightness, contrast, and frame rate determined using the respective distance between the vertices 13.

Then adjust the screen by determining the corresponding Gain, Depth, Frequency, Number of Scanlines, Time Gain Compensation, and Dynamic Range. Steps S3, S4, and S5 are performed. In this process, the gain, depth, frequency, and scanline corresponding to the three parameter values of the brightness, contrast, and frame rate are corresponding. The method for determining the number, time gain compensation (TGC) and dynamic range is widely known and practiced in the field of the present invention, such as image processing, and a detailed description thereof will be omitted. .

While watching the image adjusted in real time, the user freely adjusts the position of the input point 20 in an intuitive and real time manner so that an image of a desired image quality is displayed to display an image of a desired image quality.

Meanwhile, since the three parameter values of brightness, contrast and frame rate generally have a predetermined range of values in a general measurement environment, the brightness vertices 11, Contrast vertices 12 and frame rate vertices 13 are provided with a range of positions from the beginning, and the image can be adjusted simply by adjusting the input point 20 within that range. It is possible to do However, in the case of special measurements or observation situations, the three parameter values of brightness, contrast and frame rate may need to be adjusted to have extreme values. (For example, contrast: 10, contrast: 10, frame refresh rate: 90) For this case, step S1 of adjusting and inputting the input point 20 in the triangle shape 10 is illustrated in FIG. 3. And inputting the positions of the brightness vertex 11, the contrast vertex 12, and the frame rate vertex 13, respectively, by the user's adjustment. It is preferable.
