DICOM file format and Programming

The format of any image file is composed of two parts: the header of the parameter and the pixel data ).The headers in BMP, JPEG, And Tiff formats only describe the basic parameters of the image, such as the number of rows and columns, the number of digits used for each vertex, whether the image is compressed, and the color palette. Headers are usually fixed in length.Medical Imaging also requires many other parameters, such as basic patient data, bas

DICOM dir File Format

file: dicomdir.rar the compressed file is a sample of two dicomdir files. dicomdir is a micro-database in a tree structure. The file structure of the CD is recorded. the dicomdir tree directory is a special directory structure specified in the DICOM standard, from the top layer to the bottom layer, the thumbnail is the scaled down image. Dicomdir and thumbnails can be used to conveniently and batch Import images to prevent incorrect image op

for message exchange. This section describes the communication service and necessary upper-layer protocol support between DICOM entities in the network environment. These services and protocols ensure the effective and correct communication between application entities over the network. The network environment in DICOM includes two reference models: OSI and TCP/IP. DIC

defines the physical characteristics of the media, such as physical media format parameters, dimensions, mechanical properties, storage properties, and the organization of bit stream information. For example, a 3.5 inch double-sided high-density floppy disk in a PC environment is a physical medium defined in the DICOM standard. The corresponding parameter description is the corresponding physical media lay

We have already introduced the dataset in the second lecture. We will not repeat it here. The structure of DICOM messages is shown in figure 2.2.

Introduction to dicom communication methods and dicom standards

This article describes dicom standard and dicom communication methods. Dicom stands for medical digital image and communication. In fact, there are two aspects: "Storage" and "communication ". File data organization: Network Data Organization. The file data organization method is to parse static dicom files which have

terms is a prerequisite for ensuring accurate communication. For example, inaccurate understanding of "center" and "side" can directly cause catastrophic consequences for a surgeon who diagnoses based on radiology reports. The American pathology Association has done some work on the SNOMED standard. The terminology, also known as controlled vocabulary, is applied based on anatomy and pathology. Pathology is now a member of the DICOM Standards Committ

program. This is obviously incorrect. The DICOM Standard defines the application name as follows: the DICOM Application name uniquely identifies a service or application on the network. Moreover, a parameter of the C-MOVE service is the name of the app that moves the destination. If there are two application names on a network, the C-MOVE does not know where to move the information object.4.2 The

Research on conversion between DICOM images and BMP Images

Abstract: Through analysis of a large number of DICOM images and Analysis of DICOM standard documents, we understand the structure and composition of the image. At the same time, we analyze the BMP image to obtain the structure of the BMP image, this paper proposes a method for converting DICOM images and BMP images.Keywords
