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

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

First, background:Recently has been doing DCM related programming work, the previous project uses C + +, so use DCMTK open Source Library, and currently the team uses C # mostly, so need to turn to use the Fo-dicom library, Due to the previous column Dicom medical image processing: The use of fo-dicom to send C-find query worklist in the debugging process require
describes the parameters of various ACSE services, as shown in figure 2 ), in order to A-ASSOCIATE, A-RELEASE, A-ABORT, A-P-ABORT, P-DATA; Chapter 9th gives the STRUCTURE of various services in ACSE, that is, STRUCTURE, this part is the same as the PROTOCOL in [Part 1]. It shows the data format of the specific acse pdu during transmission. This part can also be directly obtained through the packet capture tool; similarly, complicated STRUCTURE descri
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
DIMSE Protocol specified semantics (see 9.2 and 10.2 ). Each command element is composed of an explicit tag, value length, and value range. 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. Protocol Data Unit (PDU)The Protocol Data Unit (PDUS) is an information format exchanged between peer entities. It is used
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
C-find SCU and C-find SCP is given below, which contains related comments, so it is not described in detail.The C-find SCU gives the C-find SCU code in the official readme.md of fo-dicom, as follows,cfind SCU:namespace Cfindscu{class program{static void Main (string[] args) {//constructs the C-FIND-RQ message to be sent if the Dicomcfindrequest class is viewed// It can be seen that its definition is consistent with the encoding
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
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

DICOM medical image processing: DICOM Storage operation-"storing multiple JPG image data into DCM Files", dicomdcmBackground:
In the previous article, we will continue to introduce how to save multiple JPG images to the DCM file. The lossy compressed data will be directly written into the DCM file and stored in the Multi-frame format.Save multiple JPG images to the DCM file:
To avoid ambiguity, I would like
means I'm not trying to reduce storage space, but simply want to save multiple JPEG format images into the Multi-frame DCM format for easy archival management.In the post, the Offis DICOM team's response is:1) Create Dcmfileformat object, use GetDataSet () to obtain the data body pointer;2) Use the dataset in Putandinsertxxx to 1 to write uncompressed raw image
expansion of DICOM standards. For example, DVS supports newly added security-related content in DICOM standards, in addition, DVS provides macro definitions and more detailed information prompts.The current maximum version of DVS is 1.4 (14002), where you can download the DVS (14002) to a detailed description of the two, you can refer to the following AGFA website http://www.agfa.com/healthcare/us/support/
the device has a network interface that supports TCP/IP protocol, with the support of software, it can achieve "plug and play" like PC, and it is very convenient to join the network of medical information system. In this sense, the medical information system implemented in DICOM, whether RIS or PACs, has a similar structure, as shown in 2:In the information network system with DICOM standard, all
