Abstract

In a linear track scanning imaging system and method, the imaging system may include: a ray generating unit having a plurality of ray sources that emit beams alternately, only one ray source at a time; an actuating arrangement causing an object under examination to move with respect to the linear track scanning imaging system along a linear track, leading the object to pass through a scanning area of the linear track scanning imaging system; a data collecting unit that collects projection data of the object for each ray source; an imaging unit that reconstructs an image of the object under examination based on the projection data collected for each ray source; and a display unit for displaying the reconstructed image.
