Abstract: A patient management system includes a patient unit that obtains results data from a patient device and provides for two-way communication between the patient unit and a remote database. The patient unit can communicate with the remote database to obtain encounter instruction data for a given encounter as well as to send response data for the given encounter. A back office system can also access the database to retrieve the patient data for one or more patient users. The back office system can further add or modify encounter instruction data for use during a next encounter at the patient unit. The back office system can also set a dosage for the patient that can be stored in the remote database and retrieved by the patient unit as part of the given encounter. The back office system may also employ a rules engine that can be programmed according to an established protocol and can automatically generate encounter instructions and dosage information for one or more patient.

Abstract: A scintillation detector includes a scintillation crystal directly coupled to a photomultiplier tube (PMT). The crystal/PMT subassembly is attached to a voltage divider and the entire device is hermetically sealed in a stainless steel outer case. Conductors are passed through the hermetic package from the voltage divider via a high temperature metal to ceramic pass-through. The crystal and PMT are longitudinally loaded within the outer case by springs in order to minimize vibrations in the crystal and PMT. A thermoplastic support sleeve circumscribes the crystal and the PMT to protect the crystal and PMT from excessive longitudinal loading. Preferably, the support sleeve and the crystal have similar coefficients of thermal expansion so that the crystal and the support sleeve experience similar dimensional changes due to temperature fluctuations, allowing the support sleeve to best maintain its stress-limiting function as temperature within the detector changes.

Abstract: A closed-loop stabilization system and method for a radiation detector system including a scintillator and a light sensing device for detecting the scintillation light produced in the scintillator through interaction with impinging radiation. A spectrally stable gamma ray measurement for downhole and other non-isothermal gamma ray measurement applications is obtained by use of a light source for emitting photons, preferably ultra-violet photons, into the scintillator that are not detectable by the light sensing device. The light source causes the scintillator to fluoresce at a wavelength detectable by the light sensing device, and the change in measured fluorescence is used to adjust system gain to account for variations in scintillator output attributable to environmental conditions. In this manner, the stabilization system adjusts the system gain to maintain consistency among radiation measurements over a wide temperature range.
