Library dicom

DICOM library

This library implements (partially) the DICOM protocol. This protocol is used to capture, store and distribute medical images.

From Wikipedia: The core application of the DICOM standard is to capture, store and distribute medical images. The standard also provides services related to imaging such as managing imaging procedure worklists, printing images on film or digital media like DVDs, reporting procedure status like completion of an imaging acquisition, confirming successful archiving of images, encrypting datasets, removing patient identifying information from datasets, organizing layouts of images for review, saving image manipulations and annotations, calibrating image displays, encoding ECGs, encoding CAD results, encoding structured measurement data, and storing acquisition protocols.

OPTIONS: *called_aet - If set it changes the called Application Entity Title used in the requests. Default: ANY-SCP *calling_aet - If set it changes the calling Application Entity Title used in the requests. Default: ECHOSCU
