The UCD Large Animal Ultrasound Service has a full range of equipment available for all aspects of equine, food animal and small ruminant ultrasound. We are fortunate to have two Biosound Technos ultrasound systems that allow us to evaluate 2 patients simultaneously with machines that excel at musculoskeletal and abdominal imaging. Transducers available include two 8-14 MHz linear transducers and a 5-10 MHz linear transducer for musculoskeletal use, a 4-8 MHz microconvex transducer for neonatal and small ruminant abdominal/thoracic imaging and two 2-5 MHz curvilinear transducers for adult equine abdominal and thoracic imaging. We continue to use the GE Vingmed System 5 ultrasound system, primarily for cardiac imaging for its unbeatable color Doppler imaging and excellent depth of penetration (30cm). The Vingmed also produces high quality musculoskeletal and abdominal images. Transducers available for this machine include a 2.5 MHz phased array transducer for cardiac imaging, 3.5 MHz and 5.0 MHz curvilinear transducers for abdominal imaging and a 10 MHz linear transducer for musculoskeletal and small parts imaging. Finally, we have retained an Ausonics Impact ultrasound system in our arsenal for teaching purposes and its unique ability to penetrate to 40cm of depth. We have 2.5 MHz and 3.5 MHz sector transducers, a 6.0 MHz rectal transducer and a 7.5 MHz linear transducer for the Impact.
