The DICOM Standard is under continuous maintenance, and the current official version is available at http://www.dicomstandard.org/current/. Since the history is a scanned image, you could not search the histories for the different medications that a patient has taken. This metadata can include patient health information (PHI) such as patient name, medical record number, and date of birth, as well as image acquisition parameters such as image dimensions, voxel size, repetition time (TR), and voxel data type. How does the treatment team obtain a complete view of the patients plan and history. The problem occurs when you want to view both the report and the images together. Thus, the retrieval count represents the total number of imaging examinations one can retrieve, not the absolute number of images. A RIS generated number that identifies the order for the Study.

While the DICOM standard has achieved a near universal level of acceptance among medical imaging equipment vendors and healthcare IT organizations, the standard has its limitations. Standardizing these terms in USCDI v4 would further improve health information exchange between hospitals, providers, and patients across all communities. Officially there is no "version" of the standard except the current standard, hence the "3.0" version number is no longer used.

The DICOM information object definitions[16] encode the data produced by a wide variety of imaging device types,[17] including, CT (computed tomography), MRI (magnetic resonance imaging), ultrasound, X-ray, fluoroscopy, angiography, mammography, breast tomosynthesis, PET (positron emission tomography), SPECT (single-photon emission computed tomography), Endoscopy, microscopy, nd whole slide imaging, OCT (optical coherence tomography). This data element has been tested at scale between multiple different production environments to support the majority of anticipated stakeholders. One order could lead to multiple studies.Study Instance UID is generated by the modality or by the PACS and is defined to be a globally unique identifier for that study. When a report is received by the RIS, it will link this with the order using the Accession Number. ORA-00001: (.) The PACS system does not synchronize changes to e.g. Digital Imaging and Communications in Medicine (DICOM) is the standard for the communication and management of medical imaging information and related data. New service classes were defined, network support added and the Conformance Statement was introduced.

As difficult as all these problems are, so far we have assumed that we have correctly identified the patient. The study id and accession number are information system generated numbers. DICOM Modality Worklist makes patient demographic information, order details and scheduling informationfrom a RIS available at a modality, eliminating dual data entry and guaranteeing data integrity. Then you must first do a C-FIND query to identify the study or studies with that accession number then use the Study UID returned to you by the query to pass on to the subsequent retrieve request. 2. 0x0096. Thus the studies are alway assigned at the same patient, but now I would want to identify the studies that a patient did in only one access. Having an IS interface allows this number to be retrieved and to be sent with the images. 2. GENERAL STUDY MODULE ATTRIBUTES. According to a paper presented at an international symposium in 2008, the DICOM standard has problems related to data entry. On this Wikipedia the language links are at the top of the page across from the article title.
