Private equity firm August Equity LLP said it acquired Hallmarq Veterinary Imaging Ltd., also based in the U.K.

Financial terms of the deal were not disclosed.

Hallmarq, which provides advanced diagnostics for equine and companion animals, developed the world's only magnetic resonance imaging, or MRI, scanner for the standing horse. The company also developed PetVet, an MRI system for dogs and cats.

August Equity said its backing enables Hallmarq to expand further into the U.S. market and extend its specialist offering for companion animals.
