Medical displayer system for dynamically generating LUT table and method

Abstract

The method includes a medical displayer system for dynamically generating an LUT table and a method. The medical displayer system comprises an upper computer and a displayer; the displayer comprises a microprocessor module, an FPGA module, a backlight brightness sensor module and a liquid crystal panel; the upper computer communicates with the microprocessor module in the displayer and comprises a data processing module and a color analyzer, the data obtained by the color analyzer are transmitted to the data processing module to be processed, the microprocessor module is used for carrying out LUT table dynamic calculation in the using process and transmitting the result to the FPGA module, and the FPGA module outputs the processed signal to the liquid crystal panel; a light passing hole is formed in the back face of the liquid crystal panel, and the backlight brightness sensor is arranged on the light passing hole. In the medical displayer system, DICOM correction carried out on LUT table dynamic generation is triggered when backlight brightness changes, and it is ensured that the DICOM curve is met accurately; liquid crystal panel characteristic measurement only needs to be carried out once, brightness gear limit is avoided, and meanwhile DICOM conformity is ensured.

Description

technical field [0001] The present invention relates to the field of medical display, in particular to a medical display system and method for dynamically generating a LUT table. During the use of the display, a correction LUT table is dynamically generated, and the dynamic LUT table is used to finally make the gray-scale liquid crystal medical display be able to operate when the backlight changes. Always maintain consistency with DICOM curves. Background technique [0002] Compared with ordinary LCD civil displays, professional grayscale LCD medical displays use the curve (DICOM curve) specified in Part 14 of the DICOM standard for grayscale correction, and the implementation method of the look-up table (Look-Up-Table, LUT) makes The grayscale change of the actual output image conforms to the Grayscale Standard Display Function (GSDF), so that the human eye has the ability to identify every subtle grayscale change. [0003] However, the DICOM curve is not a linearly changi...
