From Verathon Inc.;
'The BladderScan® BVI 6300 Bladder Monitor is a handheld, noninvasive ultrasound instrument prescribed by the health care provider to enable patients to monitor bladder fullness on an ongoing basis. It is easy to use and quickly provides accurate results, so the patient can make informed decisions about when voiding is necessary.'

From Verathon Inc.;
'The BladderScan® BVM 6500 enables physicians quickly and noninvasively to determine UEBW (ultrasound estimated bladder weight) and bladder volume using 3-dimensional V-mode® ultrasound. The BVM 6500 was designed to assist in diagnosis of bladder hypertrophy secondary to obstruction.'

The mirror artifact is similar to the reverberation artifact. Mirror image artifacts (mirroring) can occur if the acoustical impedances of the tissue is too much different and the ultrasound is reflected multiple times on tissue layers. The echo detected does not come from the shortest sound path, the sound is reflected off an angle to another interface so that like a real mirror, the artifact shows up as the virtual object.
An empyema or lung abscess can be simulated by a mirror image artifact of a hepatic cyst. This liver lesion can appear like a lesion within the lung because the wave is reflected off the diaphragm back into the liver. The angle of reflection is equal to the angle of incidence. The sound pulse hits the interfaces within the liver lesion and is reflected back to the diaphragm once again with an angle of reflection equal to the angle of incidence and then back to the transducer.
Also by a pelvic ultrasound scan the sound can be reflected off the rectal air at an angle so that the deep wall of an artifactual cyst represents the mirror image of the inferior and anterior walls of the bladder. Mirror image artifacts can cause other strange appearances such as invasion of a transitional cell carcinoma through the bladder wall.
Also called Cross Talk.

From Verathon Inc.;
'The Pediatric BladderScan® is the newest addition to Verathon Inc.'s trusted family of BladderScan® instruments. By enabling health care providers to measure a child's bladder volume noninvasively, this easy-to-use, handheld tool aids in the diagnosis and treatment of urinary conditions.'

(TRUS) Transrectal sonography (also called transrectal ultrasonography, transrectal echography (TRE), endorectal ultrasound (ERUS or EUS)) is an ultrasound procedure used to examine the prostate gland, the rectum or bladder.
A small, lubricated transducer placed into the rectum releases sound waves, which create echoes as they enter the region of interest. A computer creates a picture called a sonogram.
TRUS is commonly used for guidance during a prostate needle biopsy and may be used to deliver brachytherapy and monitor cancer treatment. Transrectal ultrasonography detects enlargement, tumors and other abnormalities of the prostate, rectal polyps, rectal cancer, perianal infection, and sphincter muscle injuries. TRUS is also performed on male patients with infertility to view the prostate and surrounding structures and on patients with suspected bladder conditions or disease to view the bladder.
