AI Technical Summary

Problems solved by technology

In the grayscale image, the information has been reduced to one dimension (grayscale value), and the colorization is to use this information to deduce the RGB three-dimensional situation. In the conversion, it is easy to have a grayscale value corresponding to multiple color values, that is, The same grayscale value may map to many possible color values, so there is no unique absolute positive solution when coloring grayscale images

Embodiment Construction

[0019] The brightness of the obtained black and white medical images is enhanced, and the difference in brightness is converted into 256 (2 8 ) to 4096 (2 12 ) grid gray scale (gray scale).

[0020] After the gray scale of the image is turned, the operator can measure the gray scale value of the target object with the detection pen (wand) or the buoy according to the instructions. It can also be calculated according to the grayscale data to achieve colorization or difference in chroma to strengthen image judgment.

[0021] This technology can be commonly used in black and white medical images developed at present or in the future, including ultrasound (ultrasound), x-ray, angiography (angiography), endoscopic images, CT or MRI.

[0022] On the image, the desired range can be defined and circled. This specific region (ROI, region of interest) can enhance its brightness contrast, and express the difference of different gray scales in color or chroma. The difference in gray sc...

Abstract

The invention relates to a system for enhancing the contrast of a medical image and realizing colorization, which comprises an image input device and an image processing device, wherein the image input device is used for acquiring a gray scale image file through X-ray tomography or file transfer; and the image processing device is used for converting the gray scale image file into a contrastive colored image file.

Description

technical field [0001] The invention relates to a system for strengthening the contrast grayscale and colorization of medical images. Background technique [0002] Grayscale images are used in many technological imaging, such as satellite images, medical x-ray (x-ray) images, and electron microscope images. This is mainly due to the limitations of the imaging principle of the image, so the results are often presented in the form of grayscale. If it is colored, because the eye physiology prioritizes the recognition of color contrast over the contrast of black and white images, it will not only increase the degree of recognition, but also provide more information in a certain sense. [0003] Colorization of grayscale images is a hot area. In the grayscale image, the information has been reduced to one dimension (grayscale value), and the colorization is to use this information to deduce the RGB three-dimensional situation. In the conversion, it is easy to have a grayscale va...
