Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
This method of medical ultrasound therapy can be used for various types of pain relief and physical therapy. In physics, the term "ultrasound" [1] applies to all acoustic energy with a frequency above the audible range of human hearing. The audible range of sound is 20 hertz – 20 kilohertz. Ultrasound frequency is greater than 20 kilohertz.
Some dog whistles have adjustable sliders for active control of the frequency produced. Trainers may use the whistle simply to get a dog's attention or to inflict pain for the purpose of behaviour modification. In addition to lung-powered whistles, there are also electronic dog whistle devices that emit ultrasonic sound via piezoelectric ...
Dorsal Laminectomy is the most common procedure for DLSS treatment, [1] [6] which implies the decompression or des-inflammation of soft tissues and nerve roots.↵Surgical fusion of the lumbosacral vertebrates has also been found to improve the affected vertebrae, since it reduces motion by eliminating certain nerve compressions located in the ...
The devocalization procedure does not take away a dog's ability to bark. Dogs will normally bark just as much as before the procedure. After the procedure, the sound will be softer, typically about half as loud as before, or less, and it is not as sharp or piercing. [3] Most devocalized dogs have a subdued "husky" bark, audible up to 20 metres. [4]
Ultrasound-guided hip joint injection is a joint injection in the hip, assisted by medical ultrasound. Hip and groin pain often presents a diagnostic and therapeutic challenge. The differential diagnosis is extensive, comprising intra-articular and extra-articular pathology and referred pain from lumbar spine, knee and elsewhere in the pelvis.

Veterinary surgery is surgery performed on non-human animals by veterinarians, whereby the procedures fall into three broad categories: orthopaedics (bones, joints, muscles), soft tissue surgery (skin, body cavities, cardiovascular system ...
