The number of VCT facilities increased from 23 in 2001 to more than 1000 in 2007, and the number of HIV tests taken doubled from 1.7 million tests in 2007 to 3.5 million in 2008.
VCT obtained isotropic high resolution while reducing patient doses through the improvement of X ray detection efficiency to truly realize the goal of balancing high quality images and low X ray dose.
