Abstract
A general surveillance monitor to monitor the vital physiological signs of patients undergoing examination by nuclear magnetic resonance imaging is constructed such that each functional module of the monitor is individually protected from the electromagnetic environment and high frequency parasitic currents and such that the control assembly is a computer system without any magnetic storage.
Claims4
Monitor for surveying vital physiological parameters of a patient undergoing examination in a tunnel of a nuclear magnetic resonance imaging means for detecting and analyzing signals, wherein said monitor comprises:
- a shielded principal casing;
- means for detecting vital physiological parameters of the patient;
- an assembly of surveillance modules;
- shielded conductor means for connecting the detecting means to the surveillance modules;
- a plurality of shielded housing means for surrounding each of the surveillance modules, said shielded housing means being disposed in said shielded principal casing;
- a central means for controlling and displaying information relating to the vital physiological parameters detected by the detecting means, wherein said central means is a computer system free from magnetic storage;
- wherein the shielding of said principal casing and said plurality of housing means and said conductor means shield the surveillance modules such that they operate noninterferingly with said signals in a region adjacent to the nuclear magnetic resonance imaging means.
