Abstract: A portable, wireless patient monitor may be placed with the patient in the bore of an MRI machine eliminating the need for separate cabling between the MRI machine and an external monitoring unit. In one embodiment, the patient monitor may be attached to the patient's shoulder by a harness or the like which may also serve to corral leads between the patient monitor and the patient.

Abstract: A portable, wireless patient monitor may operate in an MRI machine to monitor the patient during the scan and provides an optical display allowing the connection of the patient to the monitor when the monitor is remote from its receiving base station, for example, in the hospital room, or to provide clinical information as a freestanding monitor before and after the scan.

Abstract: A wireless in bore sensor for magnet resonance imaging provides radio frequency communication of physiological and other data signals from a battery powered unit held adjacent to the patient within the bore by using multiple diversity techniques to overcome the interfering environment of the MRI imaging system and to prevent interference with the MRI system.

Abstract: An adapter converts a scalar ECG signal into a pseudo-vector ECG signal suitable for synchronization purposes on certain MRI systems having vector ECG inputs. The pseudo ECG signal while lacking significant diagnostic information replicates sufficient ECG features for timing purposes. Different pseudo ECG signals may be synthesized for compatibility with different vector ECG signals.

Abstract: An apparatus for evaluating the alignment of both eyes of a patient objectively in primary, secondary and tertiary gaze, and the Bielschowsky head tilt positions and to diagnose for phorias, tropias and intermittent tropias. The apparatus has a head restraint and a mounted fixation target in a spaced relationship to the head restraint and having adjustments for adjusting the target along three axis. Electronic shutters are used to occlude each eye during the testing. A camera is used for imaging the eye of a patient having his head in the head restraint with his eyes aligned with the target. The camera is mounted adjacent to the target on the xyz mount.
