https://www.vetnurse.co.uk/f/nonclinical-discussions/13352/radiology-q Hey guys, This is a very vague question i&#39;m afraid........a vet in the practice was on CPD and is now looking for a radiology ball? Apparently it looks like a bendy table lamp and measures distances on images. I&#39;m sure it has a propper name! en-USTelligent Community 10https://www.vetnurse.co.uk/thread/112762?ContentTypeID=1Fri, 22 Apr 2011 20:28:38 GMT1a0763ec-3885-442c-853e-6cef656dfec5:06f50276-68e0-4ba6-a03f-be7a10f589d8Nick Shackleton <p>Just thought just before I left my old place one of the vets got hold of a perspectice tube with two metal balls in them which was to do with measurement.</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/112745?ContentTypeID=1Fri, 22 Apr 2011 13:27:59 GMT1a0763ec-3885-442c-853e-6cef656dfec5:53a4806a-bc5f-42a8-9436-50d57eb537f7Suze<p>Thanks Nick, was talking to radiologist last night who said they had balls that they place on area beind radiographed and then the software has the measurements of the balls pre programmed and this is how they measure areas!

Have known vets mark rads with pencil and use a ruler and protractor to measure length and angles. Also use on acetate and marker pwns. And with the increasing use of CR means you record measurements on the computer screen</p><div style="clear:both;"></div>
