The present invention provides a system (100) for enhancement of the image quality of a subject with less radiation exposure and high spatial resolution using CBCT technique. For this purpose, the system (100) comprises of a high resolution movable Flat Panel Imager (101), an X-Ray Tube (102) which are mounted on the rotatable Gantry (103). The cone beam X-Ray Tube (102) is mounted on opposite side of Flat Panel Imager (101). The entire Gantry (103) is supported with Base Structure (104) along with an angle of +15 degrees or −；15 degrees tilting motion. The Patient Couch Table (105) is mounted on the floor based on the gantry reference plane.
