Picture archiving and communication system.An image as stored on a picture archiving and communication system PACS.The same image following contrast adjustment, sharpening and measurement tags added by the system.A picture archiving and communication system PACS is a medical imaging technology which provides economical storage and convenient access to images from multiple modalities source machine types.Electronic images and reports are transmitted digitally via PACS this eliminates the need to manually file, retrieve, or transport film jackets, the folders used to store and protect X ray film.

Script andor a Java Applet.More robust PACS clients are full applications which can utilize the full resources of the computer they are executing on and are unaffected by the frequent unattended Web Browser and Java updates.As the need for distribution of images and reports becomes more widespread there is a push for PACS systems to support DICOM part 1.DICOM standard. Web Access to DICOM Objects WADO creates the necessary standard to expose images and reports over the web through truly portable medium.Without stepping outside the focus of the PACS architecture, WADO becomes the solution to cross platform capability and can increase the distribution of images and reports to referring physicians and patients.PACS image backup is a critical, but sometimes overlooked, part of the PACS Architecture see below.HIPAA requires that backup copies of patient images be made in case of image loss from the PACS.There are several methods of backing up the images, but they typically involve automatically sending copies of the images to a separate computer for storage, preferably off site.Querying C FIND and Image Instance Retrieval C MOVE and C GETeditThe communication with the PACS server is done through DICOM messages that are similar to DICOM image headers, but with different attributes.A query C FIND is performed as follows The client establishes the network connection to the PACS server.The client prepares a C FIND request message which is a list of DICOM attributes.The client fills in the C FIND request message with the keys that should be matched.E. g. to query for a patient ID, the patient ID attribute is filled with the patients ID.The client creates empty zero length attributes for all the attributes it wishes to receive from the server.E. g. if the client wishes to receive an ID that it can use to receive images see image retrieval it should include a zero length SOPInstance.UID 0. 00. 8,0. 01.C FIND request messages.The C FIND request message is sent to the server.The server sends back to the client a list of C FIND response messages, each of which is also a list of DICOM attributes, populated with values for each match.The client extracts the attributes that are of interest from the response messages objects.Images and other composite instances like Presentation States and Structured Reports are then retrieved from a PACS server through either a C MOVE or C GET request, using the DICOM network protocol.Retrieval can be performed at the Study, Series or Image instance level.The C MOVE request specifies where the retrieved instances should be sent using separate C STORE messages on one or more separate connections with an identifier known as the destination Application Entity Title AE Title.
