Embodiment Construction

[0041] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0042] Such as figure 1 As shown, the embodiment of the present invention provides a method for adaptively generating the default window width and window level of DICOM images, including:

[0043] Step 1: Acquire medical image data. Specifically, the original image data of the above-mentioned medical images may be the original image data collected by medical image acquisition equipment (such as CT, etc.), or it may be the image data generated after processing the original image data during the medical image processing process. , or other image sources.

[0044] Step 2: Calculate the m...

Abstract

The invention discloses a method for generating a DICOM image default window width and window level in a self-adaptive mode. The method comprises the steps of obtaining medical image data; calculatingthe maximum value and the minimum value of the image gray scale; constructing a grayscale histogram of the image according to the maximum value and the minimum value of the image grayscale; calculating all wave crest areas in the gray histogram; calculating an optimal histogram peak area corresponding to the tissue area; calculating an optimal display gray value interval of the image according tothe optimal histogram peak area, and calculating an optimal window width and an optimal window level according to the optimal display gray value interval of the image; and writing the calculated optimal window width and optimal window level into a DICOM image file to serve as default window width and window level. According to the invention, the optimal window width and the optimal window level of the DICOM image can be efficiently obtained without complex calculation and written into the DICOM file to serve as the default window width window level, so that the image is displayed more clearlyand conforms to the image reading habit.

Description

technical field [0001] The invention relates to the technical field of medical image generation, in particular to a method for adaptively generating a default window width and level of a DICOM image. Background technique [0002] DICOM files refer to medical files stored in accordance with the DICOM (Digital Imaging Communications in Medicine) standard. The main component of a DICOM file is the collection of data. This includes not only medical images, but also many information related to medical images, such as patient name, image size, etc. The window width and window level is one of the very important information. [0003] The window width is the range of CT values ​​displayed on the CT image, and the tissues and lesions within this range of CT values ​​are displayed in different simulated grayscales. Tissues and lesions with CT values ​​higher than this range, no matter how much higher the degree is, are displayed as white shadows, and there is no gray difference; on ...
