Abstract: A method for magnetic resonance imaging (MRI)-guided interstitial thermal therapy includes receiving MRI data for tissue of a patient, generating an apparent diffusion coefficient (ADC) map from the MRI data, identifying a target site for thermal therapy based on the ADC map, wherein the target site is a tumor identified by low ADC values on the ADC map, planning the thermal therapy for the target site including identifying a plurality of individual localized areas to be ablated during delivery of the thermal therapy, the plurality of individual localized areas having the lowest ADC values among the low ADC values within the target site, activating a laser to deliver the thermal therapy to the plurality of individual localized areas using a laser fiber, and monitoring progress of the thermal therapy using MR thermometry.

Abstract: A method for magnetic resonance imaging (MRI)-guided interstitial thermal therapy includes receiving MRI data for tissue of a patient, generating an apparent diffusion coefficient (ADC) map from the MM data, identifying a target site for thermal therapy based on the ADC map, wherein the target site is identified based on an area on the ADC map with a lowest ADC value, planning the thermal therapy for the target site including identifying localized areas of the target site to be ablated first during delivery of the thermal therapy, activating a laser to deliver the thermal therapy using a laser fiber, and monitoring progress of the thermal therapy using MR thermometry.

Abstract: The present invention is directed toward a distributed intelligence fiber-optic communication network in which node control processors (NCPs) associated with each network element periodically transmit identification and status information to the other NCPs in the network. Various faults in the network can thus be readily identified, and appropriate tasks for modifying the network in response to the fault (such as rerouting around a defective network element) can be carried out. Further, information continues to be distributed among the NCPs even if a break occurs in a segment of fiber in the network.

Abstract: A network communication system comprising an optical communication path and a plurality of network elements disposed along the optical communication path. A first network element coupled to the optical communication path includes a first processor and a first optical component. The status of the first optical component being monitored by the first processor. The first processor generates a first electrical signal in accordance with the status of the first optical component. The first network element also includes a service channel transmitter coupled to the first processor and emits a second optical signal to the optical communication path at a second wavelength different than the first plurality of wavelengths in response to the first electrical signal. The second optical signal being modulated in accordance with the second electrical signal.
