Imaging safety device
First Claim
1. A medical system comprising:
- a patient monitoring device That monitors physiological parameters of a patient and outputs a signal indicating values for the parameters; and
an imaging system including;
an imaging probe that directs energy into a patient;
a signal analyzer, in communication with the patient monitoring device, that analyzes The signal from The patient monitoring device and outputs an abnormality signal indicating irregularities in parameters monitored; and
a controller monitoring the signal from the signal analyzer and, when a predetermined abnormality signal is output, issues an alarm to an operator of the imaging system;
wherein the controller, upon output of a predetermined signal by the signal analyzer changes The energy output by the imaging probe to a non-zero value.

Abstract
An imaging system in which a patient monitoring device, that monitors physiological parameters of a patient and outputs a signal indicating values for the parameters, is in communication with a patient imaging system. The patient imaging system includes an imaging probe that directs energy into and receives energy from a patient; and a signal analyzer, in communication with the patient monitoring device, that analyzes the signal from the patient monitoring device and outputs a signal indicating irregularities in parameters monitored. A control unit monitors the signal from the signal analyzer and, when a predetermined signal is output, issues an alarm to the operator of the patient imaging system. The control unit can also be programed to reduce the output power of the imaging probe and/or alert a central monitoring facility in response to the output of the signal analyzer.
