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......

Ultrasound is one of the most rapidly evolving technologies in the world of human and veterinary medicine. What began as a diagnostic imaging modality only, began to be adapted for therapeutic and physiotherapy purposes over a decade ago, seeing greatest uptake in human and equine sports medicine. Now, we stand at the threshold of ultrasound as a widely used treatment method in itself. Ultrasound drug delivery With the advent of ultrasound microbubbles for contrast imaging came the possibility of using ultrasound for drug delivery. The concept was that by enclosing a drug inside......

In the past decade, 3D/4D ultrasound has evolved beyond being a mere concept or gimmick, to the point at which it can now deliver useful images. A number of private human pregnancy scanning clinics have opened up across the UK, and as such, 3D and 4D ultrasound scanning has become part of people’s consciousness. 3D refers to a still three dimensional image, whereas 4D refers to a moving one (the forth dimension is time). Here’s an explanation of 2D, 3D HD and 4D HD live technology by Maria Christopoulos: The equipment used by Maria in this......

As discussed in previous articles, ultrasound is very safe. The biggest danger in its operation is almost certainly that which is common to all electrical devices: electrical safety, trip hazards, the machine being pulled off a table and injuring an animal or person, and so on. If your scanner were to malfunction and pass an electrical charge to a person or an animal, the legal responsibility would lie with the manufacturer, right? Not necessarily. In the absence of a cooperative manufacturer willing to take responsibility (which, when purchasing from abroad, is almost guaranteed),......

We know that ultrasound deposits energy into tissue in two ways: • Vibration • Heat. Due to the fact that tissue is being affected in these ways, the potential for damage exists, and it was for this reason that the Mechanical Index (MI) and Thermal Index (TI) were created.   Mechanical Index One ‘quick fix’ image optimisation trick is to increase output power, and therefore the MI. This increases the signal-to-noise ratio, and can result in a clearer image. However, there are usually a number of other controls one can optimise first (such as......
