System and method for converting mobile device display into medical image display

The present invention relates to a system and method for converting a mobile device display into a medical image display, and more particularly to a system and method for converting a mobile device display into a medical image display standard.

Digital Imaging and Communications in Medicine (DICOM) defines the file format and network communication protocol for medical images for processing, storing, printing and transmitting digital medical images. DICOM is a communication protocol based on Transmission Control Protocol (TCP) and Internet Protocol (IP) to connect multiple network systems. For example, any system that supports DICOM-format medical instruments, servers, workstations, monitors, printers, and network devices can use digital files in DICOM format to send and receive digital medical images and patient data to integrate these subsystems. In the Picture Archiving and Communication System (PACS).

DICOM also defines the Grayscale standard display function (GSDF) standard, which is used as a display specification for grayscale medical displays. However, the current grayscale medical display on the market is expensive and is a fixed display, which results in low penetration rate, and is not conducive to medical personnel to immediately view medical images. For example, medical staff must go to grayscale medical care The monitor's workstation can be viewed to view medical images.

With the popularity of mobile devices (such as smart phones and tablets) and the advancement of non-medical displays, some non-medical displays on the market now have hardware specifications and capabilities for displaying medical images. Therefore, if a non-medical display with sufficient hardware specifications can be integrated into the medical image storage transmission system, the popularity of medical image display can be increased and the construction cost of the system can be reduced.

However, how to share digital medical images to non-medical displays and display medical images through non-medical displays with sufficient hardware specifications is an emerging topic in the field.

Accordingly, the present invention is directed to a system and method for converting a mobile device screen into a medical image display, and more particularly to a system and method for converting a tablet screen into a medical image display standard.

The invention discloses a system for converting a mobile device screen into a medical image display, comprising a main display, a first slave mobile device display and a host. The host is coupled to the primary display and the first slave mobile device display for performing a medical image sharing process, wherein the medical image sharing process includes executing an image capture program to capture the first color medical image; An image processing process for converting the first color medical image into a first grayscale medical image; converting the first grayscale medical image into a first image packet; and connecting to the first slave mobile device display Transmitting the first image packet to the first slave mobile device display, and the mobile device of the first slave mobile device display installs and executes a medical image display program.

The invention discloses a method for converting a mobile device display into a medical image display, which is used for A conversion mobile device is displayed as a medical image display system, wherein the system includes a primary display, a first slave mobile device display, and a host, wherein the method includes capturing the first color medical image; according to an image processing flow, Converting the first color medical image into a first grayscale medical image; converting the first grayscale medical image into a first image packet; and transmitting the first image packet to the first slave mobile device display, And the mobile device of the first slave mobile device display installs and executes a medical image display program.

Displays 120 and 122 can serve as an extended display for host 10 and primary display 11). Specifically, the host 10 may execute an image capturing program to respectively capture the first medical image and the second medical image; and perform the image processing process to convert the first medical image and the second medical image into the first gray, respectively. a medical image and a second grayscale medical image; respectively converting the first grayscale medical image and the second grayscale medical image into a first image packet and a second image packet; and respectively packaging the first image packet and the second image packet The mobile device displays 120 and 122, wherein the mobile device of the slave mobile device displays 120, 122 first installs and executes a medical image display program to read the first image package and the second image package.

In one embodiment, host 10 can share first medical images to slave mobile device displays 120 and 122 (eg, mirror mode, ie slave mobile device displays 120 and 122 can act as mirrored displays for host 10 and primary display 11). Specifically, the host 10 can transmit the first image packet corresponding to the first medical image to the slave mobile device displays 120 and 122, and the primary display 11 also displays the same first medical image.

Therefore, the system for converting the mobile device display into the medical image display system 1 can integrate the non-medical display having sufficient hardware specifications into the medical image storage and transmission system, thereby increasing the medical image display. Shows the penetration rate and reduces the cost of PACS construction.

Step 24: Connect to a slave mobile device display to transmit the image packet to the slave mobile device display, and the mobile device display mobile device needs to first install and execute a medical image display program.

Step 25: End.

In the medical image sharing process 2, the user can view the desktop of the main display 11 (for example, a graphical user interface (GUI)) and input a user interface (eg, a keyboard or a mouse) through the host 10. The control signal is input to control the host 10 to perform steps 21 to 24. For example, the user can select a first icon to generate a first control signal to control the host 10 to execute an image capture program to capture the first color medical image (step 21), wherein the first The icon corresponds to the image capture program. The user can select a second icon to generate a second control signal to control the host 10 to perform an image processing program (step 22), wherein the second icon corresponds to the image processing program. Make The user can select a third icon to generate a third control signal to control the host 10 to convert the grayscale medical image into an image packet (step 23). Finally, the user can select a fourth icon to generate a fourth control signal to control the host 10 to connect to the slave mobile device display 120 or 122 to transmit the image packet to the slave mobile device display 120 or 122 and the slave action The mobile device display device needs to first install and execute a medical image display program (step 24), wherein the fourth icon corresponds to an image transfer program. For example, the slave mobile device display 120 or 122 can be disposed in the mobile device, and the mobile device can receive the image package through a built-in communication interface (such as a wired or wireless communication interface); in addition, when the mobile device is installed and executed for medical imaging When sharing the medical image display program of Process 2, the image package can be read.

In one embodiment, host 10 can be connected to slave mobile device displays 120 and 122 via adapter 13 (step 24). In an embodiment, the host 10 can further compress the image package to generate a compressed image package, and then transmit the compressed image package to the slave mobile device display 120 or 122, thereby reducing the file size of the image package and saving memory space.
