The large transducer selection, most with high-frequency capabilities, provides the right tool for general imaging, radiology, and internal medicine applications.'

(TEE) Transesophageal echocardiography provides a superior view of cardiac anatomy compared with transthoracic echocardiography. TEE is performed by the introduction of a probe attached to a fiberoptic endoscope into the esophagus. Caused by the position close to the heart e.g., clot finding and the view of the mitral valve are improved.

Indications:
The piezoelectric crystal creating the acoustic power is mounted on the gastroscope that must be swallowed by the patient. This endoscopic transducer is miniaturized to approximately the size of a fingernail. Usually the probe is in place for an average of 15 minutes, to numb the surface a topical anesthetic is sprayed into the throat, in addition a conscious sedation is recommended.

(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.
