QueryRetrieve

QueryRetrieve is a standard protocol used in the field of medical imaging and healthcare information systems. It is defined by the Digital Imaging and Communications in Medicine (DICOM) standard and is designed to facilitate the retrieval of medical images and related data from Picture Archiving and Communication Systems (PACS) or other healthcare information systems. The protocol operates over a network, typically using the TCP/IP protocol suite, and is based on the HTTP protocol for communication.

The QueryRetrieve protocol consists of two main operations: Query and Retrieve. The Query operation allows a client to search for specific medical images or data based on certain criteria, such as patient ID, study date, or modality. The Retrieve operation allows the client to request and download the images or data that match the query criteria.

The QueryRetrieve protocol is widely used in healthcare settings to enable the sharing and retrieval of medical images and data between different systems and locations. It is particularly useful in radiology, where medical images are often stored in PACS and need to be accessed by radiologists, clinicians, and other healthcare professionals. The protocol is also used in other healthcare settings, such as pathology and cardiology, where medical images and data are stored and retrieved using similar systems.

In summary, QueryRetrieve is a standard protocol defined by the DICOM standard that facilitates the retrieval of medical images and related data from PACS or other healthcare information systems. It consists of two main operations, Query and Retrieve, and is widely used in healthcare settings to enable the sharing and retrieval of medical images and data.
