Odin Medical Technologies, Ltd. was founded in Israel, in 1996. Odin Medical Technologies, Inc. was established in early 2000 in the United States as a wholly owned subsidiary.
Odin Medical Technologies develops and manufactures intraoperative magnetic resonance imaging (MRI) image guidance systems designed to improve neurosurgical interventions with a special focus on minimally invasive procedures.
As of July 25, 2006, Odin Medical Technologies, Ltd. was acquired by Medtronic, Inc.

Toshiba Medical Systems started 1914 and was a leading diagnostic imaging manufacturer with departments including research, development, production, service and support of medical 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.

In March 2016 Toshiba sold its Toshiba Medical Systems for $6 billion to Japan's Canon. After regulatory approval the company got renamed to Canon Medical Systems.

(bFFE) A FFE sequence using a balanced gradient waveform. A balanced sequence starts out with a RF pulse of 90° or less and the spins in the steady state. Before the next TR in the slice phase and frequency encoding, gradients are balanced so their net value is zero. Now the spins are prepared to accept the next RF pulse, and their corresponding signal can become part of the new transverse magnetization. Since the balanced gradients maintain the transverse and longitudinal magnetization, the result is, that both T1 and T2 contrast are represented in the image. This pulse sequence produces images with increased signal from fluid, along with retaining T1 weighted tissue contrast. Because this form of sequence is extremely dependent on field homogeneity, it is essential to run a shimming prior the acquisition. A fully balanced (refocused) sequence would yield higher signal, especially for tissues with long T2 relaxation times.

(PRESTO) PRESTO is a 3 dimensional ultrafast gradient echo sequence that combines the whole brain coverage with T2* weighted imaging. PRESTO is useful for BOLD and perfusion imaging studies. In combination with parallel imaging techniques, PRESTO provides higher temporal resolution and more coverage compared to traditional multi slice imaging. In addition, the sensitivity to susceptibility artifacts and flow phenomena is reduced, compared with EPI techniques, enabling MRI scans throughout the brain including the skull base.

See also T2 Star.

(T2 Star) The characteristic time constant that describes the decay of transverse magnetization, taking into account the inhomogeneity in static magnetic fields and the spin spin relaxation in the human body. This results in a rapid loss of phase coherence and the MRI signal. The T2* time is always less than the T2 time.
