2. Image storage and retrieval
Images should be ideally stored and retrieved via a hospital based PACS. Such a system provides a long-term archive for images and allows for comparisons with previous examinations. Protocols can be built into PACS which will automatically upload the most recent examination for comparison and also apply additional post-processing algorithms (i.e. for line detection). Clinicians may also have the opportunity to add notes to images for the attention of the reporter, this is useful if they wish to confirm acknowledgement of an unexpected finding or if a feeding tube has since been removed.
