1. Apparatus for transcranial imaging, comprising:
- an ultrasound source, for location in conjunction with a cranium and configured to produce ultrasound at one or more predetermined ultrasound frequencies and focusable on a location of interest within said cranium; and
a radio receiver configured to detect radio frequency radiation emanating from said location of interest, thereby to allow detection of RF radiation induced at said location of interest by said ultrasound source, for insertion into an image.

Abstract
Apparatus for transcranial imaging comprises an ultrasound source, placed in conjunction with a cranium, producing ultrasound at one or more ultrasound wavelengths that are focused on a location of interest within the cranium. The ultrasound generates RF radiation using the acousto-electric effect and a radio receiver detects the resulting radio frequency radiation emanating from the location of interest. Different types of brain tissue, as well as healthy and diseased tissue, produce different amplitudes of RF radiation, which can be detected as the location of interest is scanned over the volume of the brain, and used to produce an image of the brain.

14. A system for transcranial imaging of a target tissue in a brain comprising:
-
a control module for producing a signal at a predetermined frequency in an ultrasound frequency range; a transducer for transducing the signal to an ultrasound signal; a focusing mechanism for focusing the ultrasound signal onto a target within the transcranial region; and a radio frequency receiver for detecting an electromagnetic signal at a frequency band that includes said predetermined frequency. - View Dependent Claims (15, 16, 17, 18, 19, 20)
