Ultrasound instrumentation: Understanding the design, operation, and implementation of ultrasound-based devices used for diagnosis or therapy.
Diagnostic Ultrasound: This involves the use of high-frequency sound waves to produce images of internal organs and tissues.
Therapeutic Ultrasound: This type of ultrasound is used to treat various medical conditions like joint pain, muscle strains, and tendinitis.
Doppler Ultrasound: This type of ultrasound uses sound waves to measure the blood flow in different parts of the body.
Contrast-Enhanced Ultrasound: It is a special type of diagnostic ultrasound that involves the use of a contrast agent, which helps to highlight certain areas of the body and create more detailed images.
HIFU (High-Intensity Focused Ultrasound): This is a non-invasive technique that uses high-intensity ultrasound waves to destroy targeted tissues without damaging the surrounding tissues.
Echo-cardiography: This technique is used to examine the heart and its functioning using ultrasound waves.
Cervical Length Ultrasound: It is a type of ultrasound used to measure the length and thickness of the cervix in pregnant women.
Intrauterine Ultrasound: It is a type of ultrasound that is used to examine the fetus during pregnancy.
Acoustic Microscopy: It is a type of microscopy that uses ultrasound waves to examine the microstructure of materials.
Acoustic Tomography: This technique is used to create 2D or 3D images of objects by scanning them with ultrasound waves.
Photoacoustic Imaging: It is a non-invasive imaging technique that uses light to generate sound waves, which are then used to produce images of tissues and organs.
Acoustic Radiation Force Impulse (ARFI) Imaging: It is a type of ultrasound that uses sound waves to measure the stiffness of tissues in the body.
"The usage of ultrasound to produce visual images for medicine is called medical ultrasonography or simply sonography, or echography."
"The practice of examining pregnant women using ultrasound is called obstetric ultrasonography."
"The machine used is called an ultrasound machine, a sonograph or an echograph."
"Ultrasound is composed of sound waves with frequencies greater than 20,000 Hz."
"Ultrasonic images, also known as sonograms, are created by sending pulses of ultrasound into tissue using a probe."
"The ultrasound pulses echo off tissues with different reflection properties and are returned to the probe which records and displays them as an image."
"Some situations may require the use of a specialized transducer."
"Most ultrasound examination is done using a transducer on the surface of the body."
"Improved visualization is often possible if a transducer can be placed inside the body."
"Special-use transducers, including transvaginal, endorectal, and transesophageal transducers are commonly employed."
"At the extreme, very small transducers can be mounted on small diameter catheters and placed within blood vessels to image the walls and disease of those vessels."
"Internal body structures such as tendons, muscles, joints, blood vessels, and internal organs can be visualized."
"Ultrasound can be used to measure some characteristics (e.g. distances and velocities)."
"The visual image formed using this technique is called an ultrasonogram, a sonogram or an echogram."
"Sound waves with frequencies greater than 20,000 Hz, which is by approximation the upper threshold of human hearing."
"Sending pulses of ultrasound into tissue using a probe creates the ultrasound images."
"The ultrasound pulses echo off tissues with different reflection properties and are returned to the probe..."
