Claim:
1. A magnetic resonance apparatus which acquires navigator signals generated from a navigator region including a body-moving first portion and a body-moving second portion, the navigator signals acquired using a coil having a plurality of channels, the magnetic resonance apparatus comprising: a scan unit configured to execute a first navigator sequence for acquiring first navigator signals generated from the navigator region using the coil; a profile generating unit configured to generate first profiles each including position information on the first portion for every channel, based on the first navigator signals received by the respective channels; a determining unit configured to determine correlations between the first profiles and a template indicative of a profile of reference for the navigator region, based on signal values of the first profiles and a signal value of the template; and a selecting unit configured to select, out of the channels, each channel used to acquire the position information on the first portion, based on the correlations, wherein the signal value of the template includes a signal value of a first polarity in a region for the first portion, and includes a signal value of a second polarity opposite to the first polarity in a region for the second portion.
