Abstract :
X-ray are used in Medical treatment field as Roentgenogram, X-ray CT, PET and so on. It is potentially demanded for using low dose X-ray for human body. We conducted K-Edge CT with photon-counting detector using cadmium telluride(CdTe) and made extracted images of Iodine which is used for contrast media at blood vessel in angiography. Though there are some noise on the others part as low dose X-ray, we can see blood vessel clearly. We can make higher contrast CT images of iodine by using high energy resolution.
