So, I can’t imagine a workplace where you would share a x-ray/ultrasound/CT/mr/PET, where you’d invite people to see it, and the people who showed up could get you in trouble with HR.
Just ask.
There’s nothing prurient about it unless you have weird motives.
It’s like showing Netter. One of the classic human anatomy books.
If you do anyone remotely scientific, there should be no problem.
Just be aware, the camera may add ten pounds. The CT scanner seems to add a lot more.
