    Abstract: A tissue ablation system includes an antenna, a microwave energy source, measurement apparatus including a signal generator and a detector, a controller, and a switch assembly arranged to alternatively electrically couple the antenna to the microwave energy source or to the measurement apparatus, wherein the controller is configured to cause the switch assembly to alternate between assessment mode and ablation mode, and wherein the controller is configured to control the delivery of ablative microwave energy during an ablation mode based at least in part on a difference between a then-current broadband reflection coefficient spectrum and a previously measured broadband reflection coefficient spectrum obtained by delivery of a spectrum of individual non-ablative microwave signals and detecting the reflection of same during respective assessment modes.

    Abstract: Microsized devices operable to emit neutrons in a selective manner are provided. The devices are configured so that the rate of neutron emission can be varied, either actively or passively. The devices comprise an a-particle emitting material and a neutron producing target material that when aligned and/or positioned a predetermined distance apart emit neutrons. The rate of neutron emission can be slowed or stopped by taking the materials out of alignment and/or attenuating the α-particles being directed toward the neutron producing target material.
