DICOM is a standard which provides protocol support for the transfer the medical images across multivendor and multimodality workstations. The standard provides way for message exchanges for sending, moving and querying about patient data across the network. There are various protocols supported by DICOM like C-Store, CMove, CFind etc. In each of these message exchange mechanism, there are basic steps involved to transfer the data. With increasing size of images which are captured from patients and increase in the IOD's supported by DICOM there is a requirement to find an optimal way to improve the performance of image transfers from one machine to another. This literature survey aims at finding out different techniques and methodologies adapted to achieve better performance in medical imaging by various researchers across the world. This literature survey is based on the latest DICOM standard 2015.
