Abstract
In one embodiment, An MRI apparatus comprising: an RF coil that includes a plurality of coil elements and can be installed in an arbitrary orientation with either a front surface or back surface brought into contact with the object; a table on which the object is placed; and processing circuitry configured to acquire an MR “Magnetic Resonance” signal in a first scan along any one axis from each of a plurality of representative coils selected from the plurality of coil elements, detect respective positions of the plurality of representative coils along the one axis based on MR signals, and determine disposition of the RF coil relative to the table based on the respective positions of the plurality of representative coils.
Claims21
An MRI apparatus, comprising:
- an RF coil that includes a plurality of coil elements and is configured to be installed in an arbitrary orientation with either a front surface or a back surface brought into contact with an object;
- a table on which the object is placed;
- a memory configured to store a data table in which a positional relationship between two or more representative coils and the disposition of the RF coil relative to the table are associated with each other;
- and
- processing circuitry configured to
- acquire a magnetic resonance (MR) signal in a first scan along any one axis from each of a plurality of representative coils selected from the plurality of coil elements,
- detect respective positions of the plurality of representative coils along the one axis based on the MR signals,
- derive the positional relationship between the two or more representative coils from the detected respective positions of the plurality of representative coils, and
- determine a disposition of the RF coil relative to the table based on the respective positions of the plurality of representative coils by using the derived positional relationship between the two or more representative coils and referring to the data table.
