Abstract
Devices and methods of creating an image of a biological object are disclosed. In one embodiment of the invention there is a plane wave ultrasonic pulse generator, an ultrasonic wave manipulation device, an ultrasonic detector and an image generator. In a method according to the invention, a biological object is imaged by emitting an unfocussed ultrasonic energy wave front, reflecting at least a portion of the ultrasonic energy wave front from the object, altering a direction of the ultrasonic energy, detecting that energy, and using the detected energy to create an image of the object.
