Introduction

The Digital Imaging and Communications in Medicine (DICOM) standard has been established in medicine. The imaging field has been widely used. The field of medical imaging includes radiology, cardiology, pathology, radiotherapy, and the use of visible light. The professional field of image equipment (such as endoscopes, microscopes). Requesters of medical imaging examinations and providers of healthcare services require fast and reliable access to reports and images. At the computer In the environment, more and more accesses to DICOM persistent objects are realized through network technology, but the data objects do not need to be copied. Clinicians need to access raw data stored in the native DICOM format, which allows dedicated software to use detailed DI- COM metadata performs various operations, or converts it into a common format (such as JPEG, PDF) that can be presented by existing applications. This document specifies a request to access DICOM persistent objects as HTTPURL/URI (see IETFRFC2396) Method of request. The HTTP URL/URI request includes an instance unique identifier (UniqueIdentifier, UID) Specify the pointer of the DICOM persistent object, and also specify the format of the result to be returned in the request response. Examples are as follows. a) (MIME) content-type (such as application/dicom or image/jpeg for images, application/DICOM, application/rtf or xml); b) content-encoding; c) As the first level report of HL7/CDA. The query URL parameters defined in this document enable the HTTP server to act as a DICOM service class user (ServiceClass User, SCU), and use the baseline DICOM function defined by DICOMPS3.4 and DICOMPS3.7 from the appropriate DICOM server Retrieve the requested object from the service class provider (ServiceClassProvider, SCP). In the future, other DICOM persistent objects and format requirements for server response will be formulated according to requirements. Health Informatics News and Communication Network access to DICOM persistent objects

1 Scope

This document specifies a web service for accessing and displaying DICOM persistent objects (such as images and medical imaging reports). The purpose of this document is to provide the results and images to healthcare professionals. This document gives a simple rule that can be passed HTTP/HTTPs protocol, use DICOMUID to access DICOM persistent objects in HTML web pages or XML documents. data It can be retrieved according to the display format specified by the requesting party (such as JPEG or GIF format) or in the local DICOM format. This document does not support network search for DICOM images. This document is only related to DICOM persistent objects (not other DICOM Object or non-DICOM object) related. Access control beyond the general security mechanism of network applications is outside the scope of this document. Note. The system that claims to comply with this document is functionally consistent with all the clauses in this document.
