[Intl_DxMedPhys] Ring Artifact in Philips Brilliance iCT

[Szczykutowicz, Timothy P]

For sure you may still use it in non affected modes (where I define non affected as either the artifact is not there at all, or does not interfere with the dx utility of the images which will vary as a function of indication), I provide our clinic with this type of guidance all the time. you need to be sure to be able to communicate what indications/protocols would be affected. Like you cannot rely on the scheduler and techs to make the call alone, it is a team effort to map modes to protocols and then communicate with a scheduler or scheduling tech (like when you have more than 1 ct scanner and a lead tech puts pts onto specific units).

One should only shut down a scanner with artifacts completely if no one around is able to triage the artifact to determine if it will cause issues with dx utility of the scanner. For artifacts that live in specific scan modes…. You don’t even need to talk to a rad to keep it running for the non affected modes. In some cases, once you demonstrate the artifact on a pt exam, rads may be okay living with it until service comes. It all is a function of the severity of the artifact and location in FOV.

That unit has an 80 mm mode, so I assume most all your non neuro peds and adult torso work would already be using 80 mm helical for speed? This may mean you have a neuro only scanner until service fixes it. Assuming you use 40 or less for spines and soft tissue brain type stuff.

Khalid, I think my talk on this is on the appm library, or DM me and we can chat. I am writing a SOP for my institution write now for this issue, since for years we just kind of treat every case like a one off. Communications during the scanner limited functioning time is really important, between rads/techs/scheduling/service engineering.

Good Day All, The Ring Artifact in Philips Brilliance iCT appears only when the full beam width is used, while it disappears with less beam width (40 mm ). Is it Okay to continue providing the service avoiding the full beam width due to delayed
Good Day All,

The Ring Artifact  in Philips Brilliance iCT appears only when the full beam width is used, while it disappears with less beam width  (40 mm ).

Is it Okay to continue providing the service avoiding the full beam width due to delayed service?

Thank you in advance,

Regards,
Khalid
