摘要： A self-loading mobile crusher system for reducing the size of debris disposed in a pile includes a vehicle having first and second sides adapted for movement on the surface of the debris pile. The vehicle includes first and second surface engaging devices disposed on each side of the vehicle. A debris crushing assembly is connected to the vehicle for movement with the vehicle. A debris transferring assembly is connected to the vehicle for movement with the vehicle for transferring debris from the pile to the crushing assembly. Disposed between the vehicle sides, adjacent the transferring assembly and connected to the vehicle for movement with the vehicle is a control structure for controlling passage of debris from the debris pile forward of the surface engaging devices to a position under the surface engaging devices.

摘要： Methods and apparatus for magnetic resonance imaging (MRI) assisted cryosurgery. Optimal probe placements and cooling parameters are calculated prior to cryosurgery using MRI data. A MRI compatible cryoprobe and a stereotactic probe positioning device are provided. The resolution of MR images is enhanced by mounting a radio frequency MR coil on the intracorporeal end of a cryoprobe. During cryosurgery the temperature distribution in the frozen region is solved by determining the boundary of the frozen region and solving the heat equation for the known boundary conditions. During cryosurgery the temperature distribution in the unfrozen region is determined by T1 measurements. The process of freezing is controled using information from the solution of the energy equation in the frozen region and temperature measurements in the unfrozen region. After cryosurgery the extent of the tissue damage may be ascertained using phosphorus-31 and/or sodium-23 spectroscopy with a special coil set on the cryosurgical probe.
