Patent ID: 8521301

Claim:
A system, comprising: a processor; and a plurality of electromagnetic radiation transmitters coupled to the processor, wherein the processor is configured with processor-executable instructions to perform operations comprising: determining a transit time of electromagnetic radiation emitted from each of the plurality of electromagnetic radiation transmitters and arriving within a volume for treatment within a subject; and based on the determined transit times, configuring and controlling each of the plurality of electromagnetic radiation transmitters to emit electromagnetic radiation having a pseudorandom waveform configured so that emitted electromagnetic radiation constructively interferes within the volume for treatment within a subject and randomly interferes outside the volume for treatment of a subject, wherein determining a transit time of electromagnetic radiation emitted from each of the plurality of electromagnetic radiation transmitters comprises: calculating a first transit time portion by dividing a first distance between each of the plurality of electromagnetic radiation transmitters and an outer surface of the subject by the speed of light in air; calculating a second transit time portion by dividing a second distance between the outer surface of the subject and the volume for treatment within the subject by the speed of light in tissues of the subject; and adding the first transit time portion and the second transit time portion.
