Toshiba Medical Systems started 1914 and is now a leading diagnostic imaging manufacturer with departments including research, development, production, service and support of diagnostic imaging equipment and systems. 1976 Toshiba America Medical Systems, Inc. (TAMS) was founded to coordinate sales and service for previously established business operations in the USA.

From Toshiba America Medical Systems Inc.;
'Enhanced navigation, visualization, quantification and communication characterize the Aplio ultrasound system, a powerful diagnostic imaging tool and flexible research instrument.'

Transurethral echography or sonography is used to detect small tumors of the urinary bladder or to visualize the urethra and surrounding muscles with special transducers. The bladder neck can be visualized using a transrectal probe.
In addition, high intensity focused ultrasound provides treatment of benign prostatic hyperplasia and adenocarcinoma of the prostate. Small catheter-based sectored tubular or planar transducers with highly directional energy deposition and rotational control are used for precise treatment. Regions of the prostate can be selective coagulatet while monitoring and controlling the treatment with MRI.

'Ultralink LLC is a medical imaging company based in St. Petersburg, Florida. We are committed to designing and providing advanced diagnostic ultrasound eye imaging systems to the worldwide health care community.
Ultralink developed the world's first very high frequency (VHF) digital ultrasound eye scanner - the Artemis. Our advanced patented technology provides images of the cornea and anterior segments of the human eye with unparalleled resolution. Further applications of this technology are being explored, to complement its value in the fields of refractive surgery and refractive implants.'

Ultrasound Systems:

(US) Ultrasound is very high frequency sound above about 20,000 Hertz. Any frequency above the capabilities of the human ear is referred to as ultrasound.
Diagnostic ultrasound imaging uses much higher frequencies, in the order of megahertz. The frequencies present in usual sonograms can be anywhere between 2 and 13 MHz. The sound beam produce a single focused arc-shaped sound wave from the sum of all the individual pulses emitted by the transducer.
