Abdominal ultrasonography, where gallstones create acoustic shadowing of the ultrasound, seen at bottom. A short-distance acoustic shadow occurs behind a building or a sound barrier. The sound from a source is shielded by the obstruction. Due to diffraction around the object, it will not be completely silent in the sound shadow. The amplitude ...
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.
Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.
New Port Richey is located at 9]. According to the United States Census Bureau, the city has a total area of 4.6 square miles (12 km 2), of which 4.5 square miles (12 km 2) is land and 0.1 square miles (0.26 km 2) (1.53%) is water.
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 ...
Ultrasound generation by a laser pulse for both the thermoelastic regime and the transition to the plasma regime was examined. [5] By comparing measurements with theoretical predictions, a description of the magnitude and direction of stresses leading to ultrasonic generation was presented for the first time.

Diagnostic medical sonography (DMS), a branch of diagnostic medical imaging, is the use of imaging by medical ultrasound for medical diagnosis. DMS uses non-ionizing ultrasound to produce 2D and 3D images of the body. In Canada, the credentialing for diagnostic medical sonography is the Canadian Association of Registered Ultrasound Professionals.
