Problems solved by technology

The medical image printed by this method has low accuracy and serious distortion, so it cannot be used for medical diagnosis
In the patent "CN103481695B A Printing Method of Medical Black-and-White and Color Mixed Images", the concentration gradient of the ink is not limited, but the color separation process is only performed, which can easily cause the ink output of a certain color ink pipe to be too large, resulting in The service life of inkjet printer nozzles is greatly shortened, and the format of the printed image is not specified, which will cause uneven printing effect

Abstract

The invention discloses a gray scale medical image printout system. The gray scale medical image printout system comprises an image processing module, a color management module and an image printing module, wherein the image processing module, the color management module and the image printing module are in sequential unidirectional connection; the image processing module is used for converting medical images in a Dicom format into medical images in a TIFF format; the color management module is used for adjusting matched color set according to window width values and window level values of themedical images; and the image printing module is used for utilizing the matched color set to print the medical images. According to the gray scale medical image printout system, image content loss isavoided, the printable gray scale medical image types are expanded, gray scale division and image distortion of the printed images are avoided, the medical images printed by an ink-jet printer conform to practical requirements of medical diagnosis, comprehensive cost is low, and the applicable medical image range is wide.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a grayscale medical image printing output system. Background technique [0002] Gray-scale medical image printing and output systems currently generally use dry laser printing systems (represented by Carestream in the United States) and dry thermal printing systems (represented by Agfa in Belgium) that can directly recognize and print gray-scale medical images in Dicom format. Representative) and thermal sublimation printing system (represented by Codonics in the United States), the hardware cost of these three systems is high, and the failure rate is high, and the medical treatment in the Dicom format with the printout OD (optical density) value ranging from 0.2 to 3.0 For images and medical images in Dicom format with an OD value ranging from 0.2 to 3.2, different types of substrates need to be used, which increases the cost and difficulty of operation.
