The types of ultrasound equipment available to sheep practitioners depend on the type of practice they are practicing. Farm animal practitioners, especially dairy cows, may use sheep B-ultrasound machines with linear probes designed specifically for each rectal examination.

High definition sheep ultrasound machine

The frequency of high-definition linear array scanning probes is usually in the range of 3.5 to 8.0 MHz. These machines generate a rectangular image, typically with an overlaid grid, allowing for some estimation of size. Such devices typically do not have more advanced features, such as image calipers or Doppler mode. Specialized or primarily small ruminant animal practitioners, especially if their cases consist mainly of dairy sheep and goats, are more likely to have portable scanners with fan-shaped scanner probes. These machines provide a wider curved field of view; Usually, their capabilities beyond basic image capture are limited.

This type of sheep ultrasound machine has poor portability, but usually has interchangeable transducers, allowing for the use of linear, convex, and sometimes more specialized transducers. These have more powerful features that allow for image processing, screen measurement, Doppler examination, and more. Although these machines are undoubtedly superior diagnostic tools, their lack of portability and susceptibility to (expensive) damage in farm environments limit their usefulness for farm veterinarians. * * * Later, ultrasound machines used for pregnancy diagnosis by amateur scanners are usually relatively simple and typically have rotating scanner arrays. This provides a very wide curved field of view (typically 270 °), allowing for simultaneous transabdominal imaging of both uterine angles, which enhances the user's ability to estimate the number of fetuses in late pregnancy.

All of the above types of machines can be used for ultrasound diagnostic investigations on sheep.
