Abstract
In one embodiment, an MRI apparatus, which is wirelessly connected to a wireless RF coil equipped with a plurality of coil elements, includes memory circuitry configured to store at least one program and processing circuitry configured, by executing the at least one program, to (a) set an imaging region of an object, (b) identify a position of each of the plurality of coil elements included in the wireless RF coil based on a signal obtained by radio communication with the wireless RF coil, and (c) select at least one of the plurality of coil elements with respect to three axes, based on positional relationship between the imaging region and the position of each of the plurality of coil elements.
Claims7
A magnetic resonance imaging apparatus, comprising:
- a wireless radio frequency (RF) coil equipped with a plurality of coil elements;
- a memory storing at least one program;
- and
- processing circuitry configured to, by executing the at least one program,
- set an imaging region of an object,
- identify a position of each of the plurality of coil elements included in the wireless RF coil, based on a signal obtained by radio communication with the wireless RF coil, and
- select at least one coil element out of the plurality of coil elements, based on receiving a sensitivity of each of the plurality of coil elements, which is estimated based on a distance between the imaging region and the identified position of each of the plurality of coil elements.
