The present invention relates to an image display system and method, and more particularly, to an image display system and method capable of transforming LCD panels of mobile devices into being compatible with medical images display standard.
DICOM (Digital Imaging and Communications in Medicine) has defined file format and network communication protocols for medical images to handle image processing to digital medical images such as storage, print, and transmission, and so on. DICOM takes TCP (Transmission Control Protocol) and IP (Internet Protocol) as basic communication protocols to communication multiple network systems. For example, any medical equipment, server, workstation, display device, printer, and network equipment that supports DICOM format may transmit and receive digital medical images and patient data, and with DICOM format integrate abovementioned equipment and subsystems into a PACS (Picture archiving and communication system).
DICOM has also defined GSDF (Grayscale standard display function) standards for grayscale medical display devices. However, the grayscale medical display devices in the current market place are expensive and are fixed display devices (non-portable), which causes low popularity and is inconvenient to medical physicians to interpret medical image instantaneously. For example, the medical physicians must go to the fixed workstation and the grayscale medical display device to interpret the medical image.
As the mobile device (e.g., smart phone and tablet computer) become more and more popular and the advance of non-medical display devices, there are some non-medical display devices in the market place have the hardware specification and capability of displaying medical images. Therefore, the popularity of the medical image display device may be increased and the cost of building PACS may be decreased if non-medical display devices place have the hardware specification and capability of displaying medical images can be integrated into PACS.
However, how to share the medical images to the non-medical display devices having the hardware specification and capability of displaying medical images to integrate the non-medical display devices into PACS has become a new topic in the industry.
Therefore, the present invention relates to an image display system and method capable of transforming LCD panels of mobile devices into being compatible with medical images display standard.
The present invention discloses an image display system transforming LCD panels of mobile devices into being compatible with medical images display standard. The image display system includes a host display panel, a first slave mobile display device and a host computer. The host display panel is configured to display a first color medical image, wherein a host grayscale image conversion function of the host display panel complies with a grayscale standard display function defined by GSDF (Grayscale standard display function) standard. The host computer is coupled to a host display panel and the first slave mobile display device, and configured to execute a process of sharing medical image. The process of sharing medical image includes executing an image capture program to capture a first color medical image; performing an image processing process to convert the first color medical image into a first grayscale medical image; converting the first grayscale medical image into a first image package; and connecting to the first slave mobile display device to transmit the first image package to the first slave mobile display device, wherein a mobile device containing the first slave mobile display device has installed and executed a medical image display program.
The present invention further discloses a method of sharing medical image for an image display system transforming LCD panels of mobile devices into being compatible with medical images display standard, wherein the image display system comprises a host display panel, a first slave mobile display device and a host computer, wherein the method is compiled into a program and stored in a memory device of the host computer. The method includes capturing a first color medical image; converting the first color medical image into a first grayscale medical image according to an image processing process; converting the first grayscale medical image into a first image package; and transmitting the first image package to the first slave mobile display device, wherein a mobile device containing the first slave mobile display device has installed and executed a medical image display program.
