Safe, effective, affordable

Two decades of advanced imaging experience lie behind Vision CT – our patented standing leg CT scanner for horses. This innovative modality, from the pioneers in Standing Equine MRI, delivers safe, effective and affordable advanced imaging for your practice.

Step up to another level in everyday lameness diagnosis.

  • Safe: a walk-in walk-out floor-level system ensures safety for you and your patient.
  • Effective: fast 3D imaging delivers detailed cross-sectional images for a conclusive diagnosis.
  • Affordable: With on-demand system support and monthly payment plans, be profitable in as few as 10-15 cases per month.
  • Backed: by Hallmarq Q-Care, our unique customer care programme.


Modular options

“The installation was very straightforward. The modular option meant the device arrived in its own purpose-built room, ready to go. The horses are all very happy walking in and out on the low ramp and we have full ongoing support from the team at Hallmarq to ensure we are maximizing its use.”

Tom McParland, Surgeon, Valley Equine Hospital

The benefits

Safer for horse and handler

The unique walk-in walk-out floor level system means easy entry and exit for the standing sedated patient. With no general anaesthesia required for the horse, and low dose radiation allowing the operator and handler to remain in the room throughout, safety for all is assured.


Minimal install and running costs allow you to offer affordable advanced imaging. With no need for a purpose-built room, the compact design, on-demand system support and monthly payment plans mean you can be profitable in as few as 8 cases per month.


Vision CT offers superb spatial resolution to locate small changes in the distal limb, with no superimposition or complex overlap of anatomy. Plus, images are in standard DICOM format and can be orientated at any angle in standard workstation software to view key structures.

Quick acquisition time

You can capture 3D image sets in 60 second scan times. When combined with our proven motion correction software, you get more than a conventional radiograph.

Clinical uses

A clear picture of everyday lameness

3D musculoskeletal imaging is within reach for your clinic, and invaluable to any practice with a significant sports medicine caseload

3D images for surgical planning

Advanced pre-operative imaging to help determine the precise nature and location of pathology

Scan multiple regions

Vision CT can be performed on any region of the distal limb

Improved detail with cone beam technology

Ideal for distal limb imaging, detecting non-displaced fractures, subtle changes in bone density and small osteophytic lesions

Bony tissue differentiation

Better differentiation of sub-chondral vs cortical bone pathology

The full safety picture

  • Easy access walk-in walk-out floor level system for safer horse positioning and more control for the handler.
  • With no general anaesthesia required, the gently sedated horse walks onto the system for easy image acquisition.
  • With less radiation than traditional fan beam CT, the technician remains in the room, behind a shielded screen, throughout the process.
  • The scan can be paused for an easy exit at any time and the horse can walk out of the system to prevent possible injury. 

The picture in practice

  • Vision CT improves your everyday equine lameness diagnosis
  • Offer a definitive diagnosis for a better treatment plan
  • The entire process is an outpatient procedure and does not require general anaesthesia
  • Backed by Q-Care, our world-class life-cycle support programme, designed to optimise your CT service

3D affordability

  • Unique business model to reduce your investment risk
  • Low installations costs – no special floor or power required
  • Low running costs with comprehensive support included
  • High case throughput with fast acquisition times
  • Run a profitable CT service with your everyday lameness caseload

“Hallmarq’s Standing Equine Leg CT is now our first port of call for complex proximal sesamoid fractures where we have concerns over configuration. Generating data sets is quick and easy and image resolution can be just as impressive as MRI.”

Preparation and sedation

  • A general physical and lameness examination should be performed prior to the procedure
  • If the foot is the area of interest, remove the shoe of the affected limb before imaging
  • Sedation protocols and procedures to suit your clinic
  • Needle or catheter administration
  • Appropriate sedation typically achieved with alpha-2 agonists +/- opioid

Position and scanning

  • The horse is sedated and walked into the Vision CT system
  • The lame leg is positioned for scanning
  • A 60-second, high-resolution 3D scan is performed with the operator remaining in the room
  • The horse is repositioned to scan either a new region or the contralateral leg if required

Post scan recovery

  • Vision CT makes outpatient visits possible
  • The horse returns to its stable to recover from sedation
  • Generally, the horse can safely return home on the same day

Diagnosis and treatment

  • Interpretation – Your chosen vet or radiologist should be available for consultation and official report distribution (usually within 24 hours)
  • Consultation – The vet and/or radiologist discusses the findings with the horse owner
  • Treatment – With a conclusive diagnosis, targeted therapies are recommended and an accurate prognosis given
  • Rehabilitation – Recommendations are provided to the client

“The system was very straightforward to install and has a simple-to-use interface. Quick acquisition time and fine bone detail make surgical planning much easier.”

Jonathon Dixon BVetMed MVetMed Dipl.ECVDI MRCVS Rainbow Equine Hospital

“slCT really complemented what the MRI had told us about the content and signal intensity and, in this case, helped with surgical planning, providing useful information on the bone margin.”

Alison Fairburn Specialist in Diagnostic Imaging BVSc DipECVDI-LA MRCVS Bell Equine Veterinary Hospital

“We are really excited to put into practice the development so far to help facilitate the move into second phase clinical trials and offer our customers a world first.”

“we are interested to see if the slCT can improve our ability to diagnose cartilage defects in coffin joints and fetlocks.”

Luis Rubio-Martinez DVM DVSc PhD DACVS DECVS DACVSMR MRCVS Sussex Equine Hospital

“With Hallmarq’s slCT, we can perform pre-surgical scans on pastern fractures whilst still in the cast or bandage. This aids decision making and determines whether a case is suitable for standing repair rather than needing a general anaesthetic.”

Henry O’Neill MVB, DVM, MS, Dipl ACVS, MRCVS, American Specialist in Equine Surgery Donnington Grove Equine Vets

“Hallmarq’s CT has delivered 3D images of feet, pasterns and fetlocks in standing horses in a practical, quick and easy way.”

“The standing leg cone-beam CT system from Hallmarq provides a safe, and convenient diagnostic modality to help produce a definitive diagnosis and guide the best treatment plan for equine patients.”

Jonathon Dixon BVetMed MVetMed DipECVDI MRCVS Rainbow Equine Hospital

“The 3D information generated from Hallmarq’s standing CT has helped us with our diagnoses and provided more information than conventional imaging modalities in many cases already.”
