- In medical images noise and artifacts are presented due to the measurement techniques and instrumentation. Because of the noise present in the medical images, physicians are unable to obtain required information from the images. The paper proposes a noise reduction method for both computed tomography (CT) and magnetic resonance imaging (MRI) which fuses the Curvelet transform based method. The performance is analysed by computing Peak Signal to Noise Ratio (PSNR).The results show the proposed method can obtain enhanced visual and de-noise effect.
