Description

Embodiments of the present invention relates to control how the mobile information terminal.

The medical image diagnostic apparatus visualizes the inside of the subject by various methods, and has various modalities such as an X-ray CT apparatus, a magnetic resonance imaging apparatus, an X-ray diagnostic apparatus, and an ultrasonic diagnostic apparatus. For example, an ultrasonic diagnostic apparatus radiates an ultrasonic pulse generated from a vibrating element provided in an ultrasonic probe into a subject, and the vibrating element emits an ultrasonic reflected wave generated by a difference in acoustic impedance of the subject tissue. It receives and collects biological information. The operator can check the moving image displayed on the monitor provided in the device in real time by simply performing a simple operation of bringing the ultrasonic probe into contact with the body surface.

When using the scanning function of the ultrasonic diagnostic apparatus, the operator scans the subject in various postures using the ultrasonic probe. For example, when scanning the blood vessels of the lower limbs, the operator needs to be in the middle waist to scan the lower limbs of the subject and direct his / her line of sight to the lower limbs of the subject. Therefore, it is difficult for the operator to directly operate the console. Further, when scanning a subject during surgery, the subject is away from the operation console of the ultrasonic diagnostic apparatus due to the arrangement of surgical equipment. On the other hand, the operator scans by bringing the ultrasonic probe close to the subject during the operation. Therefore, it is difficult for the operator to directly operate the console of the ultrasonic diagnostic apparatus during the operation.

The ultrasonic probe 11 is a device (probe) that transmits ultrasonic waves to a subject whose typical example is a living body and receives reflected waves from the subject based on the transmitted ultrasonic waves. The ultrasonic probe 11 has a plurality of piezoelectric transducers (ultrasonic transducers), a matching layer, a backing material, and the like arranged at the tip thereof. The ultrasonic probe 11 is a one-dimensional array probe in which a plurality of ultrasonic transducers are arranged along a predetermined direction.

When ultrasonic waves are transmitted from the ultrasonic probe 11 to the subject, the transmitted ultrasonic waves are reflected one after another on the discontinuity surface of the acoustic impedance of the body tissue, and are received by the ultrasonic probe 11 as an echo signal. The amplitude of this echo signal depends on the difference in acoustic impedance at the discontinuity that is to be reflected.

The system control circuit 128 is, for example, a processor that controls each component circuit of the ultrasonic diagnostic apparatus 1. The system control circuit 128 functions as the center of the ultrasonic diagnostic apparatus 1. The system control circuit 128 calls each operation program from the storage circuit 127 and executes the called program to generate an operation screen 128-1, a parameter setting function 128-2, a Software AP function 128-3, and an authentication information display function 128. -4, the authentication function 128-5 and the basic control function 128-6 are realized.

The operation screen generation function 128-1 is a function for generating operation screen data to be transmitted to the terminal device 2. Specifically, in the operation screen generation function 128-1, the system control circuit 128 receives a command signal from the terminal device 2 via the communication interface circuit 131. The command signal is a signal instructing to change the operation screen displayed on the touch panel included in the input interface circuit 21 of the terminal device 2 described later to a predetermined operation screen. The command signal includes information indicating the changed operation screen. As will be described later, when the operator 3 presses a predetermined button on the touch panel provided in the input interface circuit 21 of the terminal device 2, the system control circuit 24 of the terminal device 2 represents the pressed predetermined button.

The parameter setting function 128-2 is a function for setting parameters of ultrasonic image data transmitted from the ultrasonic diagnostic apparatus 1 to the terminal device 2 described later.

Specifically, in the parameter setting function 128-2, the system control circuit 128 performs display processing of the ultrasonic diagnostic apparatus 1 when the ultrasonic image data generated by the display processing circuit 126 is displayed on the monitor 13. The data size per frame of a predetermined ultrasonic image generated by the circuit 126, the display frame rate, and the compression rate of the predetermined ultrasonic image data are acquired from the storage circuit 127. The system control circuit 128 calculates the image data generation rate Ru based on, for example, the data size per frame of the acquired ultrasonic image, the display frame rate, and the compression rate of the ultrasonic image data.

Further, the system control circuit 128 measures the image data transfer rate Rt of the communication line between the ultrasonic diagnostic apparatus 1 and the terminal apparatus 2. The image data transfer rate Rt is an effective transmission bit rate that can be used for data transfer on the communication line between the ultrasonic diagnostic apparatus 1 and the terminal apparatus 2. The system control circuit 128 compares the calculated image data generation rate Ru with the measured image data transfer rate Rt. As a result of comparison, the system control circuit 128 compresses the compressed Ru when it is larger than Rt, for example, so that the compressed Ru becomes equal to Rt, that is, the ultrasonic image data in the image coding circuit 130 described later is compressed. Change the predetermined setting value so that the rate is higher. It should be noted that changing the predetermined set value so that the compression rate becomes higher means reducing the data size of the data compressed by the changed compression rate. Further, as a result of comparison, the system control circuit 128 does not change the compression rate at a predetermined compression rate when Ru is Rt or less.

By the way, the system control circuit 128 controls only the compression ratio in the above, but as will be described later, for example, a large-capacity DICOM (Digital Imaging and Communication) between the ultrasonic diagnostic apparatus 1 and a network system such as PACS (in System) data and the like are transferred, and the real-time property of transmitting the ultrasonic image data from the ultrasonic diagnostic apparatus 1 to the terminal apparatus 2 may not be sufficiently ensured by controlling only the compression rate. In such a case, the terminal display frame rate is controlled in addition to the control of the compression rate or instead of the control of the compression rate. That is, the system control circuit 128 executes the parameter setting function 128-2, and is high corresponding to the data size, display frame rate, and allowable limit value of the ultrasonic image data per frame of the ultrasonic image acquired from the storage circuit 127. The image data generation rate Rum is calculated based on the compression rate. The high compression rate corresponding to the allowable limit value means, for example, the highest compression rate set according to the minimum allowable image quality for a predetermined ultrasonic image. Further, the system control circuit 128 compares the calculated image data generation rate Rum with the measured image data transfer rate Rt. As a result of comparison, the system control circuit 128 is such that when Rum is Rt or less, for example, Ru after compression becomes equal to Rt, that is, at the time of compression processing of ultrasonic image data in the image coding circuit 130 described later. Change the predetermined setting value so that the compression ratio becomes higher. Further, when the Rum is larger than Rt as a result of comparison, the system control circuit 128 sets, for example, the compression rate at the time of compression processing of the ultrasonic image data in the image coding circuit 130 described later to the allowable limit value. Further, as a result of comparison, when Rum is larger than Rt, the system control circuit 128 lowers the terminal display frame rate from a preset value, for example, in addition to setting the compression rate.

Further, the system control circuit 128 uses, for example, a part of the ultrasonic image generated by the display processing circuit 126 in place of the control of the compression rate and the terminal display frame rate, or in addition to the control of the compression rate and the terminal display frame rate. The parameter may be set so as to cut it.

Specifically, in the authentication information display function 128-4, the system control circuit 128 displays the identification information on the monitor 13. The display location of the identification information may be any predetermined position on the monitor 13. The identification information is, for example, the SSID and password set by the Software AP function 128-3. Of the identification information, the password is a predetermined character, symbol, and number for authenticating whether or not the operator 3 is a legitimate user who directly performs a predetermined operation related to the ultrasonic diagnostic device 1 from the terminal device 2. It is a list of. The password may be different from the password set by the Software AP function 128-3. In this case, the password is a one-time password that is updated every communication connection between the ultrasonic diagnostic apparatus 1 and the terminal apparatus 2 or periodically. Although the password has been described as an example of the identification information required for authentication, a predetermined ID and password different from the SSID may be used as the identification information.

In the authentication function 128-5, after the password input is requested from the Software AP function 128-3 to the terminal device 2, when the response data is transmitted from the terminal device 2 to the ultrasonic diagnostic device 1 in response to the request, the response data This is a function that authenticates the user and permits a predetermined operation related to the ultrasonic diagnostic apparatus 1. Specifically, in the authentication function 128-5, the system control circuit 128 receives the response data in response to the password input request from the terminal device 2 via the communication interface circuit 131. The system control circuit 128 compares the password included in the received response data with the password displayed by the authentication information display function 128-4.
