Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference numerals even though they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In describing the components of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. Throughout the specification, when an element is referred to as being "comprising" or "comprising", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise . In addition, '... Quot ;, " module ", and " module " refer to a unit that processes at least one function or operation, and may be implemented by hardware or software or a combination of hardware and software.

1 is a diagram illustrating an ultrasound system in accordance with an embodiment of the present invention.

Referring to FIG. 1, an ultrasound system 100 according to an embodiment of the present invention includes an ADC 110, a beam former 120, a data control device 130, and a post-processing device 140.

The ADC (Analog-Digital-Converter) 110 converts a control signal received from the control unit into an electrical signal. Here, the control signal means a signal for controlling the transducer to emit the ultrasonic wave to the object. Converts them into electrical signals, and transmits them to a transducer (not shown). Each of the transducer elements converts an electrical signal into an ultrasonic signal and transmits the ultrasonic signal to the object.

The ADC 110 emits an ultrasonic signal to a target object, receives an echo signal from the target object, receives an electrical signal from a transducer (not shown) that outputs an electrical signal, converts the electrical signal received from the transducer into a digital signal . The ADC converts the echo signal into a digital signal and then transmits it to the beam former 120.

The beam former 120 may delay the control signal applied to each transducer element so that ultrasound is focused on the object. The reason for delaying the control signal is that each element has a different distance to the focal point at which the ultrasonic waves are focused on the object. The beam former 120 delays the control signal applied to each element differently according to the distance between the element and the focal point so that the ultrasound is focused at a desired focus of the object. Or the beam former 120 may cause the ultrasound to be radiated to the object without separate focusing at each transducer element.

The beam former 120 also serves to delay the digital signal converted from the electrical signal received from the respective transducer elements by the ADC 110 and to convert the digital signal into a signal having the same phase. As described above, since there is a distance difference from each element to the focal point, each converted digital signal is different in phase from each other according to the path of each ultrasonic wave. The beam former 120 converts the phase-matched digital signal through a time delay compensating a path difference along a different path. The digital signals converted into the same phase are combined with each other to perform beamforming for each scan line or frame, thereby generating beamforming data.

In transmitting the beamforming data to the post-processing apparatus 140, the data control apparatus 130 generates one or more indicators indicative of one or more indicators indicative of a data transmission environment, and outputs PRF (Pulse Repetition Frequency) is adjusted adaptively. The data control device 130 controls the transducer and the beamformer in consideration of one or more indicators indicative of a data transmission environment in transmitting data formed from the beamformer 120 to the post-processing device 140 . A detailed description thereof will be made with reference to FIGS. 2 and 3. FIG.

The post-processing device 140 processes the data formed from the beam former to display the image of the inside of the object. The post-processing apparatus 140 may include a scan conversion unit, a residual image processing unit, a display unit, and the like. The post-processing unit 140 may include a scan conversion unit to match the scanning direction of the received data using the data control unit with the pixel direction of the display unit, and map the corresponding data to the pixel position of the display unit. The post-processing apparatus 140 includes a residual image processing unit, and can filter the received data using a filter to remove the residual image of the received data. The post-processing apparatus 140 may include the display unit and may output final data from which the afterimage has been removed by the afterimage processing unit.

FIG. 2 is a diagram illustrating a configuration of a data control apparatus according to an embodiment of the present invention.

Referring to FIG. 2, a data control apparatus 130 according to an embodiment of the present invention includes a data transfer unit 210, an indicator generation unit 220, and a control unit 230.

When receiving the beamforming data from the beamformer, the data transmitting unit 210 transmits the beamforming data to the post-processing apparatus under the control of the controller 230. At this time, the data transmission unit may transmit the beamforming data to the post-processing apparatus using wired or wireless communication. For example, the data transmission unit 210 may transmit data using a wired communication such as a post-processing device and a USB, and may transmit data using a post-processing device and wireless communication such as Wifi. When the data transfer unit 210 transfers data using the USB, the data control unit 130 may be implemented as a USB controller. When the data transfer unit 210 transfers data using Wifi, The controller 130 may be implemented as an application processor (AP).

The indicator generation unit 220 is connected to the data transmission unit 210 to monitor the data transmission unit and generates one or more indicators indicative of one or more indicators indicative of a data transmission environment between the data transmission unit and the post-processing unit. At this time, the at least one indicator indicating one or more indicators indicative of the data transmission environment includes a communication quality between the data transmission unit and the post-processing apparatus, such as a data transmission rate, and whether the data transmission unit has completed transmission of the beamforming data to the post-processing apparatus .

The controller 230 adaptively adjusts the PRF that emits the ultrasonic signal according to at least one index indicating the data transmission environment received from the index generator 220. The controller 230 adjusts the transducer, It controls the part.

First, the controller 230 adjusts the PRF using one or more indicators indicative of a data transmission environment from the indicator generator 220. For example, the control unit 230 receives whether or not the data transmitting unit of the at least one index indicating the data transmission environment has completed transmission of the n-th beamforming data to the post-processing apparatus, , The transducer adjusts the PRF so that the transducer immediately emits the (n + 1) -th ultrasonic signal when the transmission of the n-th beamforming data is completed. Conventionally, even when the time that is set in advance to transmit the beamforming data to the post-processing unit has not elapsed and the n-th beamforming data to be transmitted is all transmitted to the post-processing apparatus, The ducer did not emit the (n + 1) th ultrasound signal. On the other hand, when the controller 230 of the present embodiment receives from the indicator generator 220 that the data transmitting unit has transmitted all the n-th beamforming data to the post-processing unit, the transducer immediately transmits the (n + 1) By controlling the PRF so as to emit, the data transmission efficiency can be increased and the frame rate can be increased.

The control unit 230 controls beamforming data transmission of the data transmission unit 210 using one or more indicators indicating the data transmission environment from the indicator generation unit 220. [ The control unit 230 receives a data rate among one or more indicators indicative of a data transmission environment. The controller 230 determines whether the received data rate is equal to or greater than a preset reference value. If the received data rate exceeds the predetermined reference value, the controller 230 controls the data transmitter to transmit the beamforming data to the post-processor. On the other hand, when the received data rate is smaller than a predetermined reference value, the controller 230 controls the data transmitter to prevent the beamforming data from being transmitted to the post-processor. The prior art does not adaptively control whether the data transmission unit transmits beamforming data to the post-processing unit according to the data transmission rate, so that the time when the data transmission unit transmits the beamforming data is terminated when the transmission of the beamforming data is completed It was set longer than the time allowed. On the other hand, in the present embodiment, when the data transmission rate is equal to or greater than a predetermined reference value without setting a separate beamforming data transmission time, the controller 230 divides the case where the data transmission rate is smaller than a preset reference value, Thereby controlling whether the forming data is transmitted or not.

Each component included in the data processing apparatus shown in FIG. 2 is connected to a communication path connecting a software module or a hardware module in the apparatus and operates organically with each other. These components communicate using one or more communication buses or signal lines.

FIG. 3A is a timing diagram illustrating a method of controlling data according to a conventional data control apparatus over time, and FIG. 3B is a flowchart illustrating a method of controlling data over time according to an exemplary embodiment of the present invention. Timing diagram.

The TX_Val signal is a signal that controls the transducer elements to transmit ultrasonic waves to the object, and the time for the transducer elements to transmit ultrasonic waves to the object is preset in the system. The RX_Val signal is a signal that controls the transducer elements to receive the reflected ultrasound signal from the object, which signal is also preset in the system. The Flag signal is a signal indicative of a data transmission rate among one or more indicators indicative of a data transmission environment, and has a value of 1 when the data transmission rate is equal to or greater than a predetermined reference value. The TX_Data signal corresponds to a signal for controlling beamforming data to be transmitted to the post-processing apparatus.

As shown in Figure 3a, when the control signal from the controller to be applied to the beamformer, it is applied to the signal from TX_Val t 1. It is applied to TX_Val signal after transmitting the ultrasonic transducer while out elements that period (t 1 ~ t 2) predetermined by the object, is applied to the signal from RX_Val t 2. After the transducer elements receive the echo signal for a predetermined period (t 2 to t 3 ), the TX_Data signal is applied at t 3 . In the data processing apparatus according to the related art, the period (t 3 to t 5 ) for applying the TX_Data signal is set regardless of the Flag signal. The TX_Data signal is set to a period from t 3 to t 5 , even though it takes only time t 3 to t 4 to transmit the beamformed data to the post-processing apparatus. This is because the data control apparatus according to the prior art does not control transmission of the beamforming data adaptively according to one or more indexes indicative of the data transmission environment. Therefore, when the data control apparatus transmits data to the post- worse case data rate of the one or more indicators of the sets the actual time taken (t 3 ~ t 4) data transfer period (t 3 ~ t 5) longer than that. Thereafter, the PRF signal is applied again (t 5 ) and the TX_Val signal t 6 , the RX_Val signal t 7 , and the TX_Data signal t 8 are applied again after a predetermined period has elapsed after the TX_Data is applied. Since the PRF signal, the TX_Val signal, the RX_Val signal, and the TX_Data signal are all set in advance in the ultrasonic system according to the related art, the data control device does not require consideration of the data communication environment. When the control signal is applied, the control unit controls the TX_Val signal, the RX_Val signal, and the TX_Data signal to be applied to the control unit, and to control the control unit to apply the control signal to the control unit. Therefore, according to the related art, the data control apparatus performs a simple repetitive operation (a control signal is applied every predetermined interval) without any consideration of the data communication environment. Also, according to the related art, after the TX_Data is applied, since the data transmission unit does not consider the data transmission rate in transmitting the beamforming data to the post-processing unit, even if the data transmission rate of the data transmission unit is bad, It is possible to transmit the beamforming data to the apparatus, and loss of the beamforming data to be transmitted may occur.

On the other hand, referring to FIG. 3B, a data processing apparatus according to an embodiment of the present invention controls data as follows. When applied with the control signal from the controller as in the prior art, TX_Val signal is applied (t 9), is applied to the group period after RX_Val set signal (t 10). After this time, the preset of RX_Val signal last (t 11), applied to the TX_Data signal and the control surface to receive one or more indicators indicating a data transmission environment, from the generator, the data transfer portion according to at least one indicator of the data transfer environment And controls to transmit data to the post-processing apparatus. t for the 11 ~ t 12 period, a period of Flag signals are continuously it has a value of 1, as judged by at least one or more indicators of the data rate is a predetermined reference value indicating a data transmission environment, the control unit t 11 ~ t 12 And controls the data transmission unit to transmit the beamforming data. The control unit in the data processing apparatus according to the embodiment of the present invention controls the transmission of the beamforming data adaptively according to one or more indexes indicative of the data transmission environment. Thus, unlike the prior art, No additional period is set other than the period of data transmission. In addition, the data transfer portion when the the transmission of beam-forming data to the post-processing apparatus (t 12), the controller completes the transmission of the beam-forming data to the processing unit after one or more indicators of the data portion indicating the data transfers from the indicator generator Or not. When the control unit receives the beamforming data and the data transmitting unit completes the transmission of the beamforming data to the post-processing unit, the control unit transmits the control signal without delay to adjust the PRF so that the transducer emits the ultrasonic signal. When the back control signal of the controller is (t 12), TX_Val a signal is applied (t 13), the period after the group is set RX_Val signal (t 14) is. Is the ACKNOWLEDGMENT This last (t 15) period is set in RX_Val signal, TX_Data and control section for controlling to transmit the data to the processing unit after the data transfer portion, wherein one or more indicators of the data environment from the indicator generator (Flag Signal), and controls the data transmitting unit to transmit data to the post-processing apparatus only when the data transmission rate among the at least one indicator indicating the data transmission environment is equal to or greater than a preset reference value. Referring to FIG. 3B, data is transmitted at t 15 and t 16 , respectively. As described above, the control unit in the data control apparatus according to the embodiment of the present invention adaptively controls the transmission of data according to one or more indicators indicative of the data transmission environment, determines whether or not the data transmission is completed, . Accordingly, it is possible to optimize the frame rate by varying the time for transmitting data to the post-processing apparatus, to increase the efficiency of transmission, and to prevent loss of data.

4 is a flowchart illustrating a data control method according to an embodiment of the present invention.

An ultrasonic signal is emitted to the object, an echo signal is received from the object, and an electrical signal is output (S410). The transducer receives an electrical signal obtained by converting a control signal of the control unit, emits an ultrasonic signal to a target object, receives an echo signal from the target object, and outputs an electrical signal.

The electrical signal is converted into a digital signal (S420). The ADC receives the electrical signal from the transducer and converts it into a digital signal.

The indicator generator monitors the data transmitter and generates one or more indicators indicative of a data transmission environment between the data transmitter and the post processor. The control unit receives one or more indicators indicative of a data transmission environment from the indicator generation unit.

The PRF for emitting the ultrasound signal is adaptively adjusted according to at least one index indicating the data transmission environment (S450). The control unit controls generation of a control signal of the control unit based on whether at least one of the data transmission units indicating the data transmission environment received from the indicator generation unit has completed transmission of the beamforming data to the post-processing unit. When the data transmission unit completes the transmission of data to the post-processing unit, the control unit generates a control signal to adjust the PRF so that the transducer emits the (n + 1) -th ultrasonic signal.

The transducer, the beam former, and the data transmission unit are controlled according to the adjusted PRF (S460). The control unit determines whether the data transmission rate among the one or more indicators indicative of the data transmission environment received from the indicator generator is equal to or greater than a preset reference value. When some or all of the data throughput or the data transfer rate is equal to or larger than a preset reference value, the control unit controls the data transfer unit to transfer the data to the post-processing apparatus.
