(SARGE) Spoiled GRE sequences use a spoiler gradient on the slice select axis to destroy any remaining transverse magnetization after the readout gradient, with the result of short repetition times. This type of sequences use semi-random changes in the phase of RF pulses to produce a spatially independent phase shift.

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.

(T/R) Also called transceiver coil. An RF coil that acts as a transmitter (T) producing the B1 excitation field and as a receiver (R) of the MRI signal. Such a coil requires a T/R switching circuit to switch between the two modes. A body coil is typically a T/R coil, but smaller volume T/R coils (head/extremities) are often used at high field as a possibility of reducing RF power absorption (SAR).
