| ultrasonogram | The image obtained by ultrasonography. See: echogram. Synonym: sonogram. (05 Mar 2000) |
|---|---|
| ultrasonograph | Computerised instrument used to create an image using ultrasound. Synonym: sonograph. Origin: ultra-+ L. Sonus, sound, + G. Grapho, to write (05 Mar 2000) |
| ultrasonographer | A person who performs and interprets ultrasonographic examinations. Synonym: echographer, sonographer. (05 Mar 2000) |
| ultrasonography | <investigation, procedure> A technique in which high-frequency sound waves are bounced off internal organs and the echo pattern is converted into a 2 dimensional picture of the structures beneath the transducer. (12 May 1997) |
| ultrasonography, doppler | Ultrasonography applying the doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow. (12 Dec 1998) |
| ultrasonography, doppler, colour | Ultrasonography applying the doppler effect, with the superposition of flow information as colours on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region. (12 Dec 1998) |
| ultrasonography, doppler, duplex | Ultrasonography applying the doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the doppler shift frequency. (12 Dec 1998) |
| ultrasonography, doppler, pulsed | Ultrasonography applying the doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return. (12 Dec 1998) |
| ultrasonography, doppler, transcranial | A non-invasive technique using ultrasound for the measurement of cerebrovascular haemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum. (12 Dec 1998) |
| ultrasonography, interventional | Ultrasonography using invasive or surgical procedures. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions. (12 Dec 1998) |
| ultrasonography, mammary | Use of ultrasound for imaging the breast. The most frequent application is the diagnosis of neoplasms of the female breast. (12 Dec 1998) |
| ultrasonography, prenatal | The visualization of tissues during pregnancy through recording of the echoes of ultrasonic waves directed into the body. The procedure may be applied with reference to the mother or the foetus and with reference to organs or the detection of maternal or foetal disease. (12 Dec 1998) |
| ultrasonosurgery | Use of ultrasound techniques to disrupt cells, tissues, or tracts, particularly in the central nervous system. (05 Mar 2000) |
| ultrasound | <investigation> A type of imaging technique which uses high-frequency sound waves. This is highly operator-dependent and is thought to be useful in diagnosis but not particularly accurate in the assessment of tumour response. For the latter, CT or MR imaging are more accurate. (16 Dec 1997) |
| ultrasound cardiography | Echocardiography is a diagnostic test which uses ultrasound waves to make images of the heart chambers, valves and surrounding structures. It can measure cardiac output and is a sensitive test for inflammation around the heart (pericarditis). It can also be used to detect abnormal anatomy or infections of the heart valves. (12 Dec 1998) |

Ultra (sometimes capitalised ULTRA) was the name used by the British for intelligence resulting from decryption of German communications in World War II. The term eventually became the standard designation in both Britain and the United States for all intelligence from high-level cryptanalytic sources. ...

Ultra is Depeche Mode's ninth full-length album, which was released on April 15 1997. The album is the first album after the departure of Alan Wilder, who left to focus on his solo project Recoil. The long time that separates this album from the previous was due to David Gahan's near suicide and recovery from addiction to drugs. These two events caused many to speculate the end of Depeche Mode but this didn't turn out to be the case. ...

Ultra is a comic book mini-series written by the Luna brothers; Jonathan (art and plot) and Joshua (script). The series was published by Image Comics and was released in eight issues in 2004 and 2005. The series' central character is Pearl Penalosa, who is also a superheroine called Ultra. The story deals only peripherally with traditional superhero comics themes like fighting supervillains and concentrates mainly on how being a superhero affects Pearl's personal life. ...

Founded in 1988 as a subsidiary of Konami of America, Ultra Software Corporation was a spinoff company created in an effort to get around Nintendo of America's strict licensing rules. One of these rules was that a third-party company could only publish up to five games per year for the (NES) in the US. This was hardly convenient for Konami, which has begun releasing more than ten games a year for both, the Famicom and Famicom Disk System, in Japan. ...

| ultrafiltration |
Ultrafiltration is a filtration process in chemistry that can retain solutes with relative molecular masses in the order of 100s to 1000s.It is also used in haemodialysis to clean whole blood while keeping its composition intact. In biological terms this occurs at the barrier between the blood and the filtrate in the renal corpuscle or Bowman's capsule in the kidneys. The Bowman's capsule contains a dense capillary network called the glomerus. ...
