[Intl_DxMedPhys] Barco 32 MP mammo monitor

Fri Apr 4 12:57:21 EDT 2025

More pixels also means the more potential for bad pixels. I was just looking at one of those monitors the other day. Brand new and has two pixels bad. The green element is stuck at full power despite rapidly alternately the color the monitor was requested to display.

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.

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.

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 I haven’t been able to find any references

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.
