[Intl_DxMedPhys] ACR MRI Philips Prescribed Phase FOV Question

[Henze Bancroft, Leah C]

Hello,

I have run into similar issues with some of our ACR MR submissions.  I don't have a Philips system so was working with different parameters but took the same approach you propose - fill out the form so the proper in-plane resolution was calculated at the end of the form.  The submission was accepted for ACR accreditation without issue.

Hope that helps,

Leah

Hello,

For ACR MRI submission, our Philips body/spine images have a prescribed FoV in the phase direction that is larger than the reconstructed phase FoV. (e.g., percent phase FoV is 175) to prevent aliasing.

Since the ACR form calculates the in plane resolution, I assume we should enter in the Reconstructed Phase and frequency FoVs for our submission as follows:



Freq FoV = 280

Prescribed Phase FoV = 490

Percent Phase FoV = 175

Phase FoV to be entered on the ACR data sheet should be 280 e.g., 490/1.75 = 280

Thank you for your insight,

Joe Meier
