摘要
In one embodiment, an ECG signal processing apparatus is configured to be connected with an electrocardiograph and an MRI apparatus and includes memory circuitry and processing circuitry configured to (a) store a parameter of an ECG signal as a first parameter in the memory circuitry, the ECG signal being acquired from the electrocardiograph operating in combination with the MRI apparatus in a period during which a gradient pulse is not applied by the MRI apparatus, (b) implement an adaptive filter for estimating noise mixed into the ECG signal due to the gradient pulse, by using the first parameter stored in the memory circuitry and a gradient magnetic field signal acquired from the MRI apparatus in a period during which the gradient pulse is applied, and (c) remove the noise mixed into the ECG signal in the period during which the gradient pulse is applied, by using estimated noise.
