Display device for bioelectrical and biophysical phenomena

Claim 1

A display device for vital signs of a patient during magnetic resonance imaging of the patient with an MRI system which comprises: means receiving signals representing the physiological status of the patient, said signal receiving means being in a location not subject to influences of the MRI system, said device including first display means which displays information which indicates time-serial changes in said signals and outputs transmission signals corresponding to the information so displayed, transmitting means which transmits said transmission signals to a location close to the patient, and second display means accommodated in a magnetically shielded housing located close to the patient which receives said transmission signals from said transmitting means, converting them to signals indicating the physiological condition of the patient, wherein said first display means which receives signals representing the physiological status of the patient in a location which is not subject to influences of said magnetic resonance imaging system and displays time-serial changes in said signals further includes a photographing means which photographs the images displayed on said first display means and outputs video signals.
