Abstract

The present disclosure relates to a method for configuring a radio frequency, RF, transmit assembly (200) for a magnetic resonance imaging system (300) for acquiring magnetic resonance imaging data from a subject within an imaging zone using an RF pulse sequence, the RF transmit assembly (200) comprising an RF amplifier (215) and a transmit coil (213), wherein the RF transmit assembly (200) is configurable with a set of configuration parameters. The method comprises: providing (3001) operating conditions of the RF transmit assembly, the operating conditions being indicative of at least: a property of the RF pulse sequence and a measurable parameter that influences the RF pulse sequence property when operating the RF transmit assembly using the RF pulse sequence; using (3003) a predefined machine learning model for determining, for the operating conditions, at least part of the set of configuration parameters and associated values; configuring (3005) the RF transmit assembly (200) in accordance with the determined configuration parameters and associated values.
