Can someone shed some light on modality integration in regards to MWL operation. My interpretation, possibly incorrect, is that the modality receives patient demographics and examination code as part of MWL refresh/manual update. The RIS examination code, say XR101, will need to be mapped against the equivalent examination code on the modality. For example, a request is made for a Barium meal….RIS knows this as exam code XR101….this is sent to the relevant modality where this is interpreted, via mapping, as modality code 123456 which equates to Barium meal. Is this the case? We are having issues with some vendors in this regard. Has anyone else had such issues or is it purely vendor or engineer dependent?
We too have this issue, particularly with CT and multiple exam request codes. Codes used on RIS are as per national codes but the scanners don't recognise them all.

I know that most CR vendors load up the mapped catalogues as they install new kit. Agfa, Kodak and Fuji do anyway. I think that they need to map the RIS procedure code against the hardwired procedure processing algorythms inside the CR units. I assume that other modalities do the same. However in a standard DICOM worklist feed both the raw RIS procedure code and the description get sent through if the RIS is providing the worklist. If a broker is providing the worklist this may be doing some mapping (unlikely). You really need to get your modalities synchronised with your RIS/Broker otherwise RIS/Broker will send a message to the modality saying XCHES-Chest and the same to the PACS. You must make sure that the modality does not pervert this to XR104 when it sends the images back to the PACS. Otherwise the images header will not tally with the PACS database entry.
That's right. It's more to do with processing algorithms than mapping codes per se. A barium exam will have different noise reduction, smoothing, greyscale contour, etc applied than, say, a wrist exam. So the modality needs to know that code XR101 needs processing with settings appropriate for barium meals.
I am having some issues with the display of DR and CR images on the our new display stations. The dynamic range seems to be reduced on the radiology review stations. There is no processing performed on QC station by the technologist before sending the images to PACS. I will appreciate any pointers on where to start the investigation,. THanks ---Ishtiaq

Hi Ishtiaq what type of display issues are you having with CR,DR Images?What system are you using?
