Simultaneous Reduction in Noise and Cross-Contamination Artifacts for Dual-Energy X-Ray CT
Figure 6
Example of noise masks randomly selected from one of the clinical exams. (a) Noise mask generated using the ACNR algorithm [12]. Structures such as vertebrae and ribs can be clearly seen (arrows). (b) Noise mask created using the proposed algorithm. (c) The difference image between (a) and (b). Reduction of anatomical structures is evident with the proposed algorithm.
