Abstract: A coil is used to transmit r.f. energy pulses through an object to be imaged. The pulses are transmitted at a plurality of directions coplanar with the image plane. A receiving coil picks up the transmitted r.f. energy. The received energy is converted to values corresponding to the amount of absorption of the energy by the object at a particular direction. By using r.f. frequencies having a wavelength less than the greatest dimension of the object, reflection, refraction and diffraction effects are minimized. The use of coils for transmitting and receiving allows propagating the energy with reasonable sized devices. Because tomographic techniques are used for image creation, the large wavelength does not seriously impact resolution.
