An electrical appliance such as an ultrasonic energy applicator used in conjunction with magnetic resonance apparatus is controlled so that the appliance is active only while the magnetic resonance signals from the subject are not being received. Alternatively, magnetic resonance signals received while the appliance is operating can be rejected and the magnetic resonance cycles used to acquire such signals can be repeated. RF noise from the appliance does not affect the signals which are accepted and used to form an image. |
