Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
A vocational-technical school, often called a vo-tech school, is a high school in the United States and Canada designed to bring vocational and technical training to its students. Proponents claim that students bound for college may be able to use such skills to realize a distinct educational advantage over other students in their major.
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
A sonologist is a medical doctor who has undergone additional medical ultrasound training to diagnose and treat diseases. [1] [2] Sonologist is licensed to perform and write ultrasound imaging reports independently or verifies a sonographer's report, prescribe medications and medical certificates, and give clinical consultations.
The transducer may be used in contact with the skin, as in fetal ultrasound imaging, or inserted into a body opening such as the rectum or vagina. Clinicians who perform ultrasound-guided procedures often use a probe positioning system to hold the ultrasonic transducer. [9] Compared to other medical imaging modalities, ultrasound has several ...

Cardiovascular technicians who obtain EKGs are known as electrocardiograph (or EKG) technicians. To take a basic EKG, which traces electrical impulses transmitted by the heart, technicians attach electrodes to the patient's chest, arms, and legs, and then manipulate switches on an EKG machine to obtain a reading. An EKG is printed out for ...
Ultrasound energy is transferred based on the frequency and power output of the ultrasonic waves that an ultrasound machine or device creates. Home ultrasound machines and doctor's office machines both operate between 1 and 5 megahertz , however, home machines utilize pulsed ultrasonic waves while professional ultrasound machines in a doctor's ...
