Commercial interest (market research)
Just a quick question to the group.
As I understand it, acquired images undergo a number of processing algorithms between capture and distribution onto a hospitals PACS. Then each workstation will have a number of controls (pre sets / W/L etc) which also apply algorithms to the images (which may/may not influence the diagnosis.) In addition, if the image gets sent to another hospital, one using a different system, another set of algortithms (from a different vendor) are brought into play.
My question to the group is, as each algoithm applies its own level of artefact to the image, what quality assurance systems are in place to ensure the integrity of the image, and is there a "control" to ensure the artefact hasn't compromised that integrity ?
