[Intl_DxMedPhys] [EXTERNAL] Re: Barco 32 MP mammo monitor

BARCO had this monitor on display at RSNA in December. Their reasoning for this display was to allow the radiologist to have a hanging protocol set up where you could hang four views at full resolution similar to what you could with film on a view box. Then you could use the zoom feature or a magnifying box to look at areas of interest. At least that is what I got from the quick demo they gave me.

I’d have to think it through more (thinking is hard on a Friday), but one benefit of the smaller pixel size is that it would possible to see a larger field of view at full resolution. 5 MP makes that possible with current systems, but it’s possible,

Not me and I don't believe these are Health Canada (our FDA) approved.

The pixel size is 103 um, where as say 5 MP or even 12 MP all have about 150 um instead. I don't believe this decrease in pixel size (pitch) is really that advantageous. Quoting the ACR-AAPM-SIIM "The finer pitch will not improve the spatial resolution of the underlying image data, which is determined by the imaging system, and the benefits over a pixel pitch of 0.200 mm are negligible at a viewing distance of 60 cm because of the limitations of the human visual system discussed earlier. However, the larger array size allows for viewing a larger region of the mammography image at the native, or full, resolution (ie, 100% zoom, no interpolation)."

The only real potential reasons I could see why a rad would want a 32 MP display is to buy something fancy or potentially view many sequences/images at a time (like in neuro or ENT imaging).

My two cents.

Subject: [Intl_DxMedPhys] Barco 32 MP mammo monitor

We recently had a Barco MDMC-12133 12 MP mammo monitor die.  Barco provided a quote for a new MDMC-32133 32 MP monitor as a replacement.
Coronis OneLook (MDMC-32133) - Breast imaging displays - Barco<https://urldefense.com/v3/__https:/www.barco.com/en/product/coronis-onelook-mdmc-32133__;!!KGKeukY!1F8q0GbgwPfa48bPuCNIO6XrLB49rJCBro01N9fR8Mtm7abnsH4FqtpM7FQsLSiY1o4FMj3vuLaVg3yoUGEGXRSHabsZeo266i6Ij-RxfIHQYf4LQw$>

I haven’t been able to find any references to monitors with this pixel size – experience, advantages, etc.

Does anyone have experience with the 32 MP monitors in mammography?

Thanks.
