dicom attributes

involved in standard 2The DICOM standard involves medical image, data communication, management information system and other fields. In the standard, the object-oriented description method and E-R (entity-relation) model are adopted, as a result, a large number of professional terms are introduced, which brings difficulties to the standard reading and understanding. Below we will briefly explain the frequently used technical terms and acronyms involv

definition in dicom data dictionaryVR: Value Representation optional field: the Value type dependent on the transfer syntaxDicom standard consists of 14 parts1 introduction and overview2. Consistency statement: This is a plain text description made public by the vendor.3. Information object definition (IOD): simple compound4. service class specifications: describes the structure of the service class, and describes the commands and results of these in

environment variables. It also defines the relational model between entities. For example, the relationship between a patient and a patient's exam. In this example, the relationship between the two can be described in a simple word "done". One patient performs a test. Similarly, an exam contains a series of images. Through the study of clinical activities, procedures can also be defined as standard models that define a set of entities (such as patients, examinations, images, reports) and the re

operations on medical images and related information, including the query, storage, and printing of medical images and related information. They are operations on information objects.(3) DICOM Information Objects (Part 3 and Part 6 of DICOM ). These two parts use object-oriented technology to define information object definitions and data dictionaries. They are the highest level to achieve

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

object instances. The entity-1 link model 1 defined by the DICOM query/retrieve service class is shown in.The DICOM query/retrieve service is initiated by SCU. The basic implementation process is as follows:(1) first establish the DICOM Association (association) between SCP and SCU through negotiation (negotiate ). During negotiation, SCU must specify the query/

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/

DICOM medical image processing: C-Echo and C-Store, dicomfo-dicomBackground: In the previous blog, we introduced the network transmission in DICOM, mainly referring to the original English text in DCMTK Wiki. By comparing the implementation of the dicom standard in DCMTK and fo-DICOM open source libraries, we have a mo

defined the compound and the general type of two categories of information object classes. The generic Information object class contains only those attributes that are inherent in real-world entities. Compound Information object classes can be attached to attributes that are not intrinsic to real-world entities. such as the CT Image information object class contains both the image of the original image dat

In the previous lecture, we introduced the network transmission function in DICOM standard, that is, using communication lines for DICOM information exchange. This section describes information exchange through storage media. Information such as images, diagnostic results, and inspection results is stored in storage media such as floppy disks and CDs to enable information exchange between different systems

As the DICOM Standard itself is named, the main problem to be solved by DICOM is network transmission, that is, in various network hardware and software environments, how can medical images be reliably and efficiently transmitted to the desired target computer. To this end, the DICOM standard adopts the policy of adding support for medical images on the basis of
