This research introduces an image encryption scheme combining several permutations and substitution-based chaotic techniques, such as Arnold Chaotic Map, 2D-SLMM, 2D-LICM, and 1D-MLM. The proposed method is called Half-Inverted Cascading Chaos Cipheration (HIC3), designed to increase digital image security and confidentiality. The main problem solved is the image's degree of confusion and diffusion. Extensive testing included chi-square analysis, information entropy, NCPCR, UACI, adjacent pixel...

B value is a factor that reflects the strength and timing of the gradient that will be used to generate a diffusion-weighted image. The higher the b value, the stronger the effect on diffusion. B value can be expressed in units of s/mm2 with a b value range of 500 s/mm2 to 1500 s/mm2. The use of b value in Diffusion Weighted Imaging (DWI) sequences is very important in detecting prostate cancer to distinguish malignant and benign cancer tissue because b value determines the amount of diffusion w...
