The probe should be fully sealed rectal probe, ideally 5-9 MHz frequency, providing a high resolution with a maximum penetration capability of 10cm. The probe should provide a 6cm wide image to allow full view of a single ovary without panning. For performing later pregnancy diagnosis a deeper penetration will be required. The ability to store images whilst on the farm is becoming essential, allowing the practitioner to further diagnose upon returning to the safer environment of the surgery. Video prints or PC archiving can then be performed in the safety of the surgery rather than the farm environment.
Portability is also a major consideration when using the scanner on farm.
Size, weight and voltage requirement are all important factors. The ability to power the scanner form a battery source may be required in some situations. Equine Muscleskeletal Tendon scanning requires a high resolution image and sophisticated software. A measurement facility and ability to store images are essential for a detailed examination. The probe, ideally 7-10 MHz frequency, should have a flexible stand off, to allow a good contact around the contours of the leg and to offset any superficial imaging from the reverberation of the probe surface.
