Abstract

The first successful imaging by laser absorption computed tomography of actual in vitro biological objects with two-dimensional resolution has been achieved by means of Coherent Detection Imaging (CDT) method for noninvasive and noncontact biomedical measurements. This novel method is based on the optical heterodyne detection technique and the image reconstruction using the projection slice theorem from sets of line integrals of laser absorption along a large number of rays crossing the object with the parallel beam geometry.
