Medical image printing device and medical image printing system thereof

Abstract

Disclosed is a medical image printing device for printing, on the basis of printing image data, a diagnostic image on a paper medium, in which the color values of each pixel are obtained from the printing image data; each pixel is determined as a color pixel or a grayscale pixel, and the grayscale pixel is further determined as a black pixel or a white-gray pixel; and each pixel is printed on the basis of the reset color values of the corresponding pixel.

Description

technical field [0001] The invention relates to a medical image printing device and a medical image printing system for printing diagnostic images used to assist medical diagnosis in the medical field. Background technique [0002] In the medical field, diagnostic images are formed by photographing certain body parts of the patient, such as the chest cavity and the brain. The doctor diagnoses the patient's illness based on such diagnostic images, and the patient also needs to carry and save a diagnostic image. In the printing method for diagnostic images, it is more traditional to print the diagnostic images on the film medium through a film printer. However, this kind of film medium is not only expensive, but also cannot be folded and is inconvenient to carry. , Long-term exposure is likely to affect the preservation of diagnostic images, and the material is difficult to degrade and is not environmentally friendly. The diagnostic image formed on the film medium is a black-...

Problems solved by technology

[0004] However, when the existing color printing device prints a black and white diagnostic image, since the color printing device realizes printing through the superimposition of cyan (C), magenta (M), and yellow (Y) color toners, although for black When the bottom part is printed, all color toners are used in the maximum amount to be as deep and black as the black part of the film medium. However, for the diagnostic image part, when printing different degrees of gray between black and white, it is still Color toner will be used, so the gray part of the diagnostic image will have a color cast, which will affect the accuracy of the doctor's medical diagnosis

In order to avoid such a color cast problem, there is also a technical solution of using a black and white printing device to print a black and white diagnostic image. In a black and white printing device, only black toner is used for gray printing. When printing the black background part of the diagnostic image, using only black toner often results in the blackness of the black background part being not deep enough, which makes it difficult for doctors to adapt to the observation habit of such a low black background part, and it is difficult to ensure Optimal visibility and diagnostic accuracy for diagnostic images
