Ultrasound is used in a variety of applications and their benefits cannot be undermined. These machines serve a lot of professions and assist doctors and veterinary surgeons to perform their tasks in a smooth manner. These devices are used extensively in the process of detecting objects and also measuring distances. Current diagnostic ultrasound technology uses probes containing an acoustic ultrasound transducer to send pulses of ultrasound in the body. When the mechanical wave comes upon a boundary between two different materials energy is reflected back to the ultrasound transducer. This reflected energy echo is detected by the probe.
Ultrasound transducers produce images of muscle and soft tissue and are useful for defining borders between solid and fluid filled spaces. These transducers provide live images enabling operators to select the most useful sections for rapid diagnoses. They show the structure and function of internal organs and assist in identifying blockages, stenosis and other vascular abnormalities.
Modern ultrasound systems use the best transducers technology that are put together with excellent processors and have a user friendly interface. The image quality depends mainly on the ultrasound transducer which is at the front end that transmits and receives the mechanical energy. It is important to get the right probe to get the best image out of a small veterinary ultrasound scanner. Before selecting the probe an individual must know it’s frequency range and it’s type. A higher frequency produces a higher resolution image, but the ultrasound wave will not penetrate deeply into the patient. A lower frequency means you will get a decrease in image resolution, but the ultrasound beam will be able to penetrate to a greater distance.
Most small animal ultrasound scans are performed at a depth of 2 - 15 centimeters. A frequency range of 4-10 MHz will allow you to scan within these depths. A modern electronic probe can scan at multiple frequencies while an older mechanical probe only operates at a single, fixed frequency. There are a number of reputed retailers who provide ultrasound accessories for sale and you must select a company who have a good reputation in the market so that you can get products of the best quality.
