Nanosonics is a ASX-listed company in the healthcare industry which manufactures and distributes ultrasound probe disinfectors and other related technologies. It has offices in Australia, the U.S. and Canada, the United Kingdom and Europe, [2] employing more than 300 people.
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 ...
From the probe tip, a beam of continuous wave ultrasound is directed through the esophageal wall into the aorta and reflects off the moving blood back to the probe; the Doppler effect is used to directly measure the velocity of the blood (by the shift in frequency of the reflected ultrasound signal compared to the original beam).
Ultrasound probe (curvilinear type) is used for examination of superficial structures. Abdominal ultrasonography (also called abdominal ultrasound imaging or abdominal sonography ) is a form of medical ultrasonography ( medical application of ultrasound technology) to visualise abdominal anatomical structures.
Upstream and downstream stenosis refers to the location of the stenotic site relative to the ultrasound probe. Upstream stenosis means the location of stenosis is located before the ultrasound probe. It causes a marked decrease in peak systolic velocity when compared to end-diastolic velocity, causing marked reduction in resistance index.
The ultrasound catheter tip is slid in over the guidewire and positioned, using angiography techniques so that the tip is at the farthest away position to be imaged. The sound waves are emitted from the catheter tip, are usually in the 20-40 MHz range, and the catheter also receives and conducts the return echo information out to the external ...
Endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy (insertion of a probe into a hollow organ) is combined with ultrasound to obtain images of the internal organs in the chest, abdomen and colon. It can be used to visualize the walls of these organs, or to look at adjacent structures.
A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
