Below is the same structure in a French Bulldog, imaged on three leading ultrasound machines, all of which are popular for abdominal scanning in small animals – and particularly for canine pregnancy scanning.

Siui Apogee 1000 Lite:

This highly portable machine is popular with fertility clinics and well-established mobile pregnancy scanning businesses who demand the best.

The below image was taken with harmonics turned on, at 4.5MHz.

ScanX Portable Ultrasound Machine:

The ScanX ultrasound machine comes with its own software app, allowing you to run it off any Windows laptop or Android device.

This was taken with a microconvex probe, at 6.5MHz.

Elite 5600 Ultrasound Machine:

The Elite 5600 is a popular entry level machine for dog pregnancy scanning due to it ease of use, reliability, and excellent image quality for a sub-£2000 scanner.

It was set at the highest frequency available with its default convex probe (higher frequency microconvex probes are available upon request).
