The operation of the application may be understood, and the operation of the ultrasound diagnostic application may be understood as the operation of the mobile terminal 200.

2 shows a configuration of a portable ultrasound diagnostic apparatus 100 according to an embodiment of the present invention.

The portable ultrasound diagnostic apparatus 100 according to the embodiment of the present invention includes a transducer 110 and a main circuit unit 120.

To pass. The transducer 110 may be formed of a piezoelectric element array module or a microfabricated ultrasonic transducer. The piezoelectric element array module may be configured such that a large number of piezoelectric elements, for example, 64, 128, 192, etc. are arranged in an array form. As a piezoelectric element, a piezoelectric ceramic (lead zirconate titanate, PZT) having good electroacoustic conversion efficiency may be used. A voltage of +100 V to -100 V may be used as a voltage of an electric pulse for driving the piezoelectric element.

For example, the transmitting and receiving unit 121 may be configured as a switch for connecting the TX circuit and the piezoelectric element array module when the ultrasonic transmission, and for connecting the RX circuit and the piezoelectric element array module when receiving the echo.

The pulse generator 122 generates an electrical pulse to be applied to the transducer 110 to generate an ultrasonic pulse.

The analog-digital converter 123 converts the echo signal transmitted from the transceiver 121 to a digital signal.

The beamformer 124 performs TX beamforming and RX beamforming. TX beamforming is to cause the pulse generator 122 to generate an appropriate electric pulse using a parameter corresponding to the transducer 110. For example, when the ultrasound is transmitted, the energy of the ultrasound is focused on a focal point at a specific distance.

RX beamforming is to perform data conversion on the digital signal from the analog-to-digital converter 123 to the transducer 110, for example, each piezoelectric element according to the position and reception time of the piezoelectric element when receiving the echo signal To generate the scan line data by time delaying the electrical signal from the summation and adding the time delayed signal, and to generate the frame data of a plurality of scan line data. Frame data is usually composed of m ㅧ n sized echo data (where m is the number of echo data per scanline, n is the number of scanlines constituting a frame), and each echo data is a brightness value. It usually has a value between 0 and 255.

The data processor 126 processes the frame data generated by the beamformer 124 in accordance with setting values of various parameters so that a clearer ultrasound image can be obtained. Such parameters typically include a gain, a time gain compensation, a gray map, a dynamic range, a contrast, and the like.

Gain is a parameter for adjusting the brightness of the image as a whole bright or dark. TGC is a parameter used to compensate for the decrease in the size of an ultrasound signal according to the depth of the human body. The TGC value corresponds to a gain for each depth section. The gray map is a function for changing a brightness value of a specific region of echo data. 3 shows some examples of gray maps. Dynamic range is a ratio of the maximum value and the minimum value of an ultrasound image signal, expressed in dB scale. Contrast is a parameter for adjusting the difference between light and dark areas.

If the measured second illuminance value is the same as the previously stored illuminance value or is within a predetermined similar range, in step 720, the mobile terminal 200 retrieves the stored parameter setting value corresponding to the previously stored illuminance value. For example, as shown in FIG. 6, when the parameter setting values corresponding to 100 lx and the parameter setting values corresponding to 200 lx are stored, the measured second illuminance value is 100 lx or a predetermined similar range ( For example, within 5 lx), the set values of the stored parameters corresponding to 100 lx are recalled.

In operation 725, the mobile terminal 200 sets the parameter setting value to the setting value loaded in operation 720.

If the measured second illuminance value is different from a previously stored illuminance value or is out of a predetermined similar range in step 715, the portable terminal 200 may set the parameter setting interface 210 so that a user may set a parameter setting value in step 730. In step 735, when the user sets the parameter setting value through the parameter setting interface 210, the mobile terminal 200 stores the setting value set by the user in correspondence with the second illuminance value in step 740. .

Is a flowchart of a parameter setting method.

In operation 810, the portable terminal 200 generates a third illuminance value by measuring the illuminance with an illuminance sensor provided in the portable terminal 200.

In operation 820, the portable terminal 200 determines whether the measured third illuminance value is the same as a previously stored illuminance value or within a predetermined similar range.

If the measured third illuminance value is the same as the previously stored illuminance value or is within a predetermined similar range, the processes of operation 720 of FIG. 7 are performed.

If the measured third illuminance value is different from the previously stored illuminance value or is outside the predetermined similar range, in step 830, the mobile terminal 200 determines whether the third illuminance value is between the two stored illuminance values.

If the third illuminance value is a value between the two previously stored illuminance values, in step 840, the mobile terminal 200 may determine the parameters corresponding to the third illuminance values from the stored setting values of the corresponding parameters. Calculate the set value. In this case, the mobile terminal 200 may calculate the setting values of the parameters corresponding to the third illuminance value by interpolating (eg, linear interpolation) the setting values of the stored parameters corresponding to the two illuminance values, respectively.

For example, as shown in FIG. 6, when the parameter setting values corresponding to 100 lx and the parameter setting values corresponding to 200 lx are stored, the measured third illuminance value is between 100 lx and 200 lx. If the value is set, the set values of the parameter corresponding to the third illuminance value may be calculated by interpolating the set values of the parameter corresponding to 100 lx and the set values of the parameter corresponding to 200 lx. For example, if the measured third illuminance value is 150 lx, which is the intermediate value between 100 lx and 200 lx, the setting values of gain, TGC, DR, and contrast corresponding to 150 lx are set to the corresponding values of 100 lx and 200 as shown in the following table. It can be calculated as an intermediate value of the setting value corresponding to lx.

100 lx 150 lx 200 lx Gain 20 25 30
TGC

(One) 5 6 7 (2) 7 8 9 (3) 9 10 11 (4) 11 12 13 DR 30 dB 35 dB 40 dB Contrast 50% 60% 70%

Similarly, the gray map corresponding to 150 lx may be a gray map of an intermediate form between the gray map corresponding to 100 lx and the gray map corresponding to 200 lx.

In operation 850, the mobile terminal 200 sets the parameter setting value to the setting value calculated in operation 840.

If the third illuminance value is not a value between two previously stored illuminance values at step 830, the third illuminance value cannot be obtained through interpolation of the stored illuminance values, and thus, the mobile terminal 200 at step 855. Provides a parameter setting interface 210 so that the user can set the parameter setting value. If the user sets the parameter setting value through the parameter setting interface 210 in step 860, the mobile terminal 200 is set in step 870. Stores the setting value set by the user in correspondence with the third illuminance value.

According to an embodiment, even when the parameter setting value is set to the setting value calculated from the previously stored setting value in step 850, the mobile terminal 200 sets (ie, changes) the user setting value of the parameter in step 855. Parameter setting interface 210 may be provided. In this case, if the user changes the parameter setting value through the parameter setting interface 210, the portable terminal 200 may store the setting value set by the user corresponding to the third illuminance value in step 870.

In step 880, the mobile terminal 200 transmits the setting value (ie, the setting value calculated from the previously stored setting value) set in step 850 or the setting value set by the user in step 860 to the portable ultrasound diagnostic apparatus 100.
