1. A method for generating an image of an object within a region, comprising: transmitting radiation, via a radiation transmitter of a radiation transmission system, into the region; receiving, via a radiation receiver of a radiation receiver system, reflections of the transmitted radiation from a plurality of sites on the object within the region; generating, via a processor, coarse image data of the object at a first resolution based on the received radiation reflections; identifying a portion of interest on the object based on the coarse image data; transmitting ultrasound via an ultrasonic transmitter into the region; receiving, via an ultrasonic receiver, ultrasonic reflections of the transmitted ultrasound from the portion of interest on the object within the region; generating fine image data of the portion of interest on the object at a second resolution based on the received ultrasonic reflections using compressed image sensing techniques, wherein the second resolution is greater than the first resolution; determining a first kinematic value associated with the portion of interest on the object based on the fine image data generated using the received ultrasonic reflections; and modifying a state of an entertainment device based on the determined first kinematic value associated with the portion of interest on the object.
