A CT detector capable of energy discrimination and direct conversion is disclosed. The detector includes multiple layers of semiconductor material with the layers having varying thicknesses. The detector is constructed to be segmented in the x-ray penetration direction so as to optimize count rate p ...
A limited use medical probe is disclosed, including a memory for maintaining a use value. The medical probe is coupled to a medical device that inhibits its function when the use value reaches a predetermined threshold value, preventing improper use of the probe. The probe memory may also store iden ...
An integrated medical monitoring and alert system for monitoring a medical therapy delivered to a patient and patient physiological parameters is disclosed. The medical monitoring system preferably includes a central monitoring system and one or more of a therapeutic device, a patient monitor, and a ...
An integrated medical monitoring system comprising at least one patient monitor, at least one central monitor, and at least one remote access device which are tied together through an integrated communications link is disclosed. The communications between various components of the system are bi-dire ...

An improved pulse oximeter (sensor and monitor) uses a plurality of wavelengths selected to provide sensitivity to both oxygen saturation and deviations in tissue site characteristic(s) from conditions at calibration. The monitor detects and/or removes the effects of deviations on SpO
An improved pulse oximeter is disclosed. The pulse oximeter includes audio signal generation means, controlled by algorithms in a processing element which continuously transform the signals from the sensor into signal quality information. This information is converted into an audio signal and annunc ...
A signal processing method, preferably for extracting a fundamental period from a noisy, low-frequency signal, is disclosed. The signal processing method generally comprises calculating a numerical transform for a number of selected periods by multiplying signal data by discrete points of a sine and ...
