Embodiment Construction

[0019] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways than those described here, and those skilled in the art can make similar extensions without departing from the connotation of the present invention. Accordingly, the present invention is not limited to the specific embodiments disclosed below.

[0020] see figure 1 , figure 1 Schematic diagram for DICOM datasets and data structures. The DICOM standard uses the prescribed data structure to encode various medical information and image data in the form of information objects and business class descriptions to form a standard DICOM format. ...

Abstract

Disclosed are a window modulation method and a device of a medical image and a real-time display method of the medical image. The window modulation method of the medical image comprises the steps: obtaining the medical image which is in a DICOM form and comprises image data of a medical object; obtaining a maximum value, a minimum value and an image window value of the medical image based on the image data; confirming a conversion area of the medical image according to a conversion formula, and creating a conversion table which corresponds to the conversion formula; and converting the image data into a display numerical value according to the conversion table. Compared with the prior art, the window modulation method of the medical image has the advantages that a windowing display technology is adopted, real-time display of the DICOM medial image is achieved in a universal computer, due to the window modulation method, processing range of the image data is narrowed, calculated amount of switch of the image data is decreased, display speed is remarkably improved, and requirements on real-time display under dynamic and continuous adjustment on the window value are met.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a medical image window adjustment method and device, and a medical image real-time display method. Background technique [0002] In the mid-1990s, the American College of Radiology and the National Electrical Manufacturers Association developed the medical digital image archiving and transmission standard DICOM (Digital Imaging and Communication in Association), which provides interface standards and interaction for various medical imaging equipment produced by different manufacturers. protocol. [0003] Since general-purpose computers cannot directly support the display of DICOM medical images, it is necessary to convert DICOM files into file formats supported by other computers, such as Device Independent Bitmap (DIB), etc. Due to the large dynamic range of medical image data, the pixel depth is usually not lower than 4096 gray levels. Therefore, it is difficult for a general d...
