Abstract: A magnetic resonance imaging system adaptively and dynamically adjusts color and brightness of illuminators mounted on the inside of a bore in response to a scan sequence used for magnetic resonance imaging or the state of a patient in order to relieve discomfort during magnetic resonance imaging. An illuminator control unit selects and determines optical characteristics of the illuminators in response to a scan sequence or the state of a patient.

Abstract: A signal input user interface apparatus comprises an input device including, a plurality of buttons, a light waveguide, and a plurality of light transmission members. The plurality of light transmission members being respectively coupled to the plurality of buttons insertable in the light waveguide to change characteristics of light passing through the light waveguide and in response to activation of an individual button a corresponding respective transmission member is inserted inside the waveguide. A receiver device including a light source is configured to emit light into the light waveguide. A sensor is configured to measure characteristics of light passing through the waveguide including passing through inserted transmission members.
