The new standard of care in equine imaging is here.


Equina™ by Asto CT™ is a multi-slice helical CT that allows simultaneous imaging of two limbs of a standing, sedated equine patient. Equina™ has scanned hundreds of equine patients around the world. Without the need for general anesthesia, scanning is safe, simple and standing.

“The CT has changed the way we can evaluate lameness and orthopedic injury in the distal limb and has virtually replaced radiography (X-rays) as the gold standard diagnostic for disease of the teeth and skull,” says Samantha Morello, clinical associate professor of large animal surgery at the SVM.

Why Equina?

Simple: Remote control positioning and a wide field of view enables simultaneous imaging of two limbs with a 30 second scan time.

Flexible:  The Equina™ robotic gantry allows imaging of equine limbs to the mid-carpus/tarsus, and imaging of the head & neck.

Diagnostic: Equina™ uses modern multi-slice CT scanning providing high-quality images to detect early signs of subtle stress responses.

Rugged: The Equina™ scanner has been proven to withstand the demands of transit and the requirements of routine equine use.

Safe: No anesthesia required. Low radiation exposure risk for patients and operators.

Equina in clinical practice

On November 24, 2018 the first Equina was commissioned at the University of Wisconsin School of Veterinary Medicine in Madison, WI. Early testing efforts have focussed on the diverse value of Equina.

Optimising operations

●    Define appropriate sedation protocols

●    Minimise scan times

●    Test in multiple sizes & breeds

Demonstrate detection

●    Detect pathology in Thoroughbred limb specimens with break-down injuries

●    Equina detection matches traditional CT detection of early signs of stress fractures

Evaluate clinical cases

●    Equina standing CT identifies more pathology than standard radiographs

●    Scans were well tolerated by equine patients


Equina™ offers very low radiation leakage and dose levels to allow handlers and operators to stay with the equine patient for greater safety.


Equina™ is accessed at ground level, allowing for rapid setup and scanning. Simply lead the horse to the target ring, position, and scan. Patients are in and out in 10 minutes.


Equina™ images bone and soft tissue of limb pairs up to carpus or tarsus of standing equine patients, making it ideal for detecting pathology under weight-bearing conditions.
