  • Patent number: 12226352
    Abstract: The present disclosure provides a mounting assembly for attaching medical equipment to a patient table. In one particular embodiment, the present disclosure provides a mounting assembly for attaching a magnetic field generator to a patient table. The mounting assembly allows for the secure attachment of the magnetic field generator to the patient table while also allowing for easy adjustment of the positioning and location of the magnetic field generator, even after the patient is on the table. In many embodiments the mounting assembly is comprised of a mounting apparatus that attaches directly to the patient table and first and second side rails that attach to the magnetic field generator and are configured to slidably attach to the mounting apparatus. In some embodiments, the mounting apparatus and side rails are constructed of a material that provides little or no interference with the magnetic field generator.
