The Animal Ultrasound Association was established to improve the standard of ultrasound imaging for animals in the United Kingdom and, eventually, beyond. This was largely in response to the experiences of canine scanners who adopted ultrasound technology several years ago in England, Wales and Scotland in order to scan their own animals and offer a service for others. For these people, learning how to scan well and safely was essential: there were few alternatives. Many didn’t even have access to a veterinarian who owned a scanner, or at least not one with......

This page is a continuation of the discussion on Tissue Specific Imaging. Accurate measurement of fat depth and muscle thickness is very important in certain applications. If the speed of sound is assumed to be traveling at 1540m/s, but is in fact traveling at 1430m/s through fat, a hypothetical 10cm fat thickness would be overestimated by 0.77cm. The mathematics of this is as follows: Speed = distance/time, so time = distance/speed When scanning through 10cm of soft tissue: t = (2*0.10m)  / 1540m/s (speed of sound through soft tissue) t = (2*0.10) / 1540......

The Scan Pad is a basic black and white portable ultrasound system, but is equipped with a wide range of functions and the ability to customise its operation for more advanced users. This is vital for researchers, scientists and veterinarians working in highly specialised areas. It can even be important for the serious lay scanner, who may, in time, expand the scope of their work to cover a wide range of species. The ability to customise one’s machine to different species and applications is clearly very important. For those just starting out......

Sonographer Yvette Lovis and I scanned recently some cows at the Museum of Kent Life, having scanned their sheep in 2015. Afterwards, they asked us if we’d check their pigs for pregnancy. We advised them that we may not be able to see anything, but that we’d it a go anyway. We were not successful. Yesterday in our Facebook group, I asked those recently trained in pregnancy scanning to explain why it was that we were unable to obtain useful images using the equipment we had brought along for scanning cows. Most people......
