The 1_1 element and the 1_2 elements E1_2 to the 1_N elements E1_N can be arranged along the first direction D1, and the first ultrasonic array 110 can transmit the first ultrasonic transmission signal UT1 using the 1_1 element E1_1, the 1_2 elements E1_2 to the 1_N elements E1_N. The second ultrasonic array 120 includes a plurality of second direction elements arranged along a second direction D2 perpendicular to the first direction D1, transmits a second ultrasonic transmission signal UT2, and can be arranged on one side SD1 of the first ultrasonic array 110. For example, the plurality of second direction elements may include a 2_1 element E2_1, and a 2_2 element to a 2_N element E2_N. The 2_1 element E2_1, and the 2_2 element to the 2_N element E2_N may be arranged along a second direction D2 perpendicular to the first direction D1, and the second ultrasonic array 120 may be arranged perpendicular to one side SD1 of the first ultrasonic array 110. The second ultrasonic array 120 may transmit a second ultrasonic transmission signal UT2 using the 2_1 element E2_1, and the 2_2 element to the 2_N element E2_N.
[0031] The array control unit 200 can provide a control signal for controlling the first ultrasonic array 110 and the second ultrasonic array 120. The volume measurement unit 300 can provide volume information VI of a measurement region MR included in an image area generated based on a first ultrasonic reception signal UR1 received by the first ultrasonic array 110 and a second ultrasonic reception signal UR2 received by the second ultrasonic array 120.
[0032] In one embodiment, when the first ultrasonic array 110 and the second ultrasonic array 120 are placed at a predetermined position on the human body, the first ultrasonic array 110 and the second ultrasonic array 120 can be turned on alternately in order to receive the first ultrasonic reception signal UR1 and the second ultrasonic reception signal UR2. For example, the multiple times can include a first time T1, a second time T2, a third time T3, a fourth time T4, and a fifth time T5. The time interval from the first time T1 to the second time T2 can be a first time interval TI1, and the time interval from the second time T2 to the third time T3 can be a second time interval TI2. In addition, the time interval from the third time T3 to the fourth time T4 can be a third time interval TI3, and the time interval from the fourth time T4 to the fifth time T5 can be a fourth time interval TI4.
[0033] For example, the center of the first ultrasonic array 110 may be located at the first point P1 during the first time interval TI1 and the second time interval TI2. In this case, during the first time interval TI1, the ultrasonic volume measurement device 10 may drive the first ultrasonic array 110 based on the first control signal CS1 to transmit the first ultrasonic transmission signal UT1 and receive the first ultrasonic reception signal UR1 reflected from the target object. Meanwhile, during the first time interval TI1, the ultrasonic volume measurement device 10 may turn off and not drive the second ultrasonic array 120 based on the second control signal CS2. During the second time interval TI2, the ultrasonic device may turn off and not drive the first ultrasonic array 110 based on the first control signal CS1, while the ultrasonic device may drive the second ultrasonic array 120 based on the second control signal CS2 to transmit the second ultrasonic transmission signal UT2 and receive the second ultrasonic reception signal UR2 reflected from the target object. In one embodiment, the volume measuring device according to the present invention is located at a first point P1 of a human body during a first time interval TI1 and a second time interval TI2, and can obtain both a first ultrasound image UI1 and a second ultrasound image UI2 of an object photographed at the first point P1. The first ultrasound image UI1 and the second ultrasound image UI2 can be stored in a database, and the volume measuring unit 300 can provide volume information VI of a measurement region MR included in an image area generated based on a first ultrasound reception signal UR1 received by the first ultrasound array 110 and a second ultrasound reception signal UR2 received by the second ultrasound array 120.
[0034] Next, during the third time interval TI3 and the fourth time interval TI4, the center of the first ultrasonic array 110 may be located at the second point P2. In this case, during the third time interval TI3, the ultrasonic volume measurement device 10 may drive the first ultrasonic array 110 based on the first control signal CS1 to transmit the first ultrasonic transmission signal UT1 and receive the first ultrasonic reception signal UR1 reflected from the target object. Meanwhile, during the third time interval TI3, the ultrasonic volume measurement device 10 may turn off and not drive the second ultrasonic array 120 based on the second control signal CS2. During the fourth time interval TI4, the ultrasonic volume measurement device 10 may turn off and not drive the first ultrasonic array 110 based on the first control signal CS1, while the ultrasonic volume measurement device 10 may drive the second ultrasonic array 120 based on the second control signal CS2 to transmit the second ultrasonic transmission signal UT2 and receive the second ultrasonic reception signal UR2 reflected from the target object. In one embodiment, the volume measuring device according to the present invention is positioned at a second point P2 of the human body during a third time interval TI3 and a fourth time interval TI4, and can obtain both a first ultrasound image UI1 and a second ultrasound image UI2 of the object photographed at the second point P2. The first ultrasound image UI1 and the second ultrasound image UI2 can be stored in a database, and the volume measuring unit 300 can provide volume information VI of the measurement region MR included in an image area generated based on a first ultrasound reception signal UR1 received by the first ultrasound array 110 and a second ultrasound reception signal UR2 received by the second ultrasound array 120.
[0035] In one embodiment, the second ultrasonic array 120 may transmit a second ultrasonic transmission signal UT2 having a steering angle SD corresponding to a predetermined angle to a measurement site MR included in an image area, and receive a second ultrasonic reception signal UR2 reflected from the measurement site MR. For example, in order to obtain an image including the measurement site MR using the second ultrasonic array 120, a delay applied to a plurality of second direction elements included in the second ultrasonic array 120 may be changed. When the delay applied to the second direction elements is changed, the steering angle SD of the second ultrasonic array 120 may be changed.
[0036] The ultrasonic volume measuring device 10 according to the present invention includes a plurality of second direction elements arranged along a second direction D2 perpendicular to a first direction D1 in which the first ultrasonic array 110 is arranged, and can accurately grasp volume information VI of a measurement area MR included in an imaging area using a second ultrasonic array 120 arranged on one side SD1 of the first ultrasonic array 110.
[0037] Although the above describes an operation of alternately scanning the first ultrasonic array 110 and the second ultrasonic array 120 in a time division manner, the ultrasonic device 10 according to the present invention can also transmit ultrasonic transmission signals using the first ultrasonic array 110 and the second ultrasonic array 120 simultaneously, receive ultrasonic reception signals reflected from a target object using the first ultrasonic array 110 and the second ultrasonic array 120 simultaneously, and then process the signals to obtain an ultrasonic image.
[0038] In addition, the ultrasound volume measuring device 10 according to an embodiment of the present invention can also measure the three-dimensional volume of the bladder by using the first ultrasound array 110 to measure the length of the deepest part of the bladder, and using the second ultrasound array 120 arranged at a 90 degree angle to the first ultrasound array 110 to measure the height of an image obtained from the bladder.
[0039] FIG. 5 is a diagram for explaining an image providing unit included in the ultrasound volume measuring device of FIG. 1, FIG. 6 and FIG. 7 are diagrams showing a first ultrasound image generated using a first ultrasound array included in the ultrasound volume measuring device of FIG. 1, and FIG. 8 and FIG. 9 are diagrams showing a second ultrasound image UI2 generated using a second ultrasound array included in the ultrasound volume measuring device of FIG. 1.
[0040] 1 to 9, the ultrasound volume measuring device 10 may further include an image providing unit 310. The image providing unit 310 may provide a first ultrasound image UI1 corresponding to the first ultrasound reception signal UR1 and a second ultrasound image UI2 corresponding to the second ultrasound reception signal UR2 for each array position where the first ultrasound array 110 and the second ultrasound array 120 are arranged. For example, when the center of the first ultrasound array 110 is arranged at the first point P1, a first_1 ultrasound image U1_1 generated based on the first ultrasound reception signal UR1 received by the first ultrasound array 110 may be illustrated as shown in FIG. 6, and the height and width of the measurement site MR illustrated in FIG. 6 may be A1. Next, a second ultrasound transmission signal UT2 is transmitted to the measurement site MR using the second ultrasound array 120, and a second_1 ultrasound image U2_1 generated based on the second ultrasound reception signal UR2 received from the measurement site MR may be illustrated as shown in FIG. 8, and the width of the measurement site MR illustrated in FIG. 8 may be A1.
[0041] Next, the first ultrasonic array 110 and the second ultrasonic array 120 may move to a second point P2. When the center of the first ultrasonic array 110 is located at the second point P2, a first_2 ultrasonic image U1_2 generated based on a first ultrasonic reception signal UR1 received by the first ultrasonic array 110 may be illustrated as in FIG. 7, and the height and width of the measurement site MR illustrated in FIG. 7 may be A2. Next, a second ultrasonic transmission signal UT2 is transmitted to the measurement site MR using the second ultrasonic array 120, and a second_2 ultrasonic image U2_2 generated based on a second ultrasonic reception signal UR2 received from the measurement site MR may be illustrated as in FIG. 9, and the width of the measurement site MR illustrated in FIG. 9 may be A2.
[0042] The volume measurement unit 300 can provide volume information VI of the measurement site MR based on a first ultrasound image UI1 generated according to a first ultrasound reception signal UR1 received by the first ultrasound array 110 and a second ultrasound image UI2 generated according to a second ultrasound reception signal UR2 received by the second ultrasound array 120. For example, the volume information VI of the measurement site MR can be obtained using parameters including the height and width of the measurement site MR included in the 1_1 ultrasound image U1_1 and the width and steering angle of the measurement unit included in the 2_1 ultrasound image U2_1.
[0043] In one embodiment, the volume measuring unit 300 may calculate maximum width information, which is the maximum width of the measurement site MR, based on the first ultrasound image UI1 provided for each array position, and calculate maximum width information, which is the maximum width of the measurement site MR, based on the second ultrasound image UI2 corresponding to the first ultrasound image UI1, to provide volume information VI of the measurement site MR. For example, when the center of the first ultrasound array 110 is disposed at the second point P2, the height and width of the measurement site MR included in the first_2 ultrasound image U1_2 may be maximum, and the width of the measurement site MR included in the second_2 ultrasound image U2_2 may be maximum. In this case, the volume measuring unit 300 may provide maximum volume information VI of the measurement site MR using parameters including the height and width of the measurement site MR included in the first_2 ultrasound image U1_2, the width of the measurement site MR included in the second_2 ultrasound image U2_2, and the steering angle. The parameters may be used to correct the width of the measurement site MR included in the second_2 ultrasound image U2_2.
[0044] FIG. 10 is a diagram for explaining a steering angle applied to the ultrasonic volume measuring device of FIG. 1, FIG. 11 is a diagram for explaining an operation mode of the ultrasonic volume measuring device of FIG. 1, and FIG. 12 is a diagram for explaining an example of a steering angle applied to the ultrasonic volume measuring device of FIG. 1.
[0045] 1 to 12, in one embodiment, an angle between a first straight line LN1 connecting the array position to a maximum image point MP corresponding to a maximum image depth MD in a first ultrasound image UI1 corresponding to maximum width information and a second straight line LN2 connecting a center CA1 of the second ultrasound array 120 to the maximum image point MP may be a reference angle RD, and a steering angle SD may be larger than the reference angle RD. For example, in order to obtain an image including a measurement site MR using the second ultrasound array 120, a delay applied to a plurality of second direction elements included in the second ultrasound array 120 may be changed. When the delay applied to the second direction elements is changed, a steering angle SD of the second ultrasound array 120 may be changed. When the steering angle SD of the second ultrasound array 120 is set to be larger than the reference angle RD, a wider second direction ultrasound image including the measurement site MR may be obtained. In one embodiment, the array position may be set based on the center of the first ultrasound array 110.
[0046] In one embodiment, the operation mode OM of the ultrasound volume measuring device may include a scan mode SCM and a search mode SEM. In the scan mode SCM, maximum width information of the measurement region MR included in the image area may be calculated by the first ultrasound image UI1 provided by the first ultrasound array 110. In the search mode SEM, when a position equal to the maximum width information is detected while scanning using the first ultrasound array 110, maximum width information of the measurement region MR may be calculated by using the second ultrasound array 120.
[0047] For example, while the ultrasonic volume measuring device 10 operates in the scan mode SCM, the ultrasonic volume measuring device 10 may move to a first point P1, a second point P2, and a third point P3, and scan the height and width of the measurement region MR using the first ultrasonic array 110 to calculate the area information. The area information of the first point P1 to the third point P3 may be stored in a database. Thereafter, the ultrasonic volume measuring device 10 may operate in the search mode SEM. When the ultrasonic volume measuring device 10 operates in the search mode SEM and detects a second point P2 corresponding to the same position as the maximum area information while scanning using the first ultrasonic array 110, the ultrasonic volume measuring device 10 may transmit a second ultrasonic transmission signal UT2 to the measurement region MR using the second ultrasonic array 120, and calculate the maximum width information of the measurement region MR based on the second ultrasonic reception signal UR2 received from the measurement region MR.
[0048] In one embodiment, the steering angle SD may be set to increase or decrease in sequence according to a predetermined angle interval. For example, when the steering angle SD is set to a first angle, the steering angle SD may be set to an angle increased by 15 degrees from the reference angle RD, and when the steering angle SD is set to a second angle, the steering angle SD may be set to an angle increased by 30 degrees from the reference angle RD. Also, when the steering angle SD is set to a third angle, the steering angle SD may be set to an angle increased by 45 degrees from the reference angle RD. A user of the ultrasound volume measuring device 10 according to the present invention may adjust the steering angle SD to obtain a proper image of the surroundings including the measurement region MR.
[0049] The ultrasonic volume measuring device 10 according to the present invention includes a plurality of second direction elements arranged along a second direction D2 perpendicular to a first direction D1 in which the first ultrasonic array 110 is arranged, and can accurately grasp volume information VI of a measurement area MR included in an imaging area using a second ultrasonic array 120 arranged on one side SD1 of the first ultrasonic array 110.

The volume measuring unit 300 may provide volume information VI of a measurement region MR included in an image area generated based on a first ultrasound reception signal UR1 received by the first ultrasound array 110 and a second ultrasound reception signal UR2 received by the second ultrasound array 120.

[0052] In one embodiment, the array control unit 200 may include a first control unit 210 and a second control unit 220.
