摘要： 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.

摘要： 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.
