    This study explores digital image processor design for rapid MR image synthesis. A 16-bit processor can achieve 0.4% error, synthesizing images in under 600 ms.

    Area of Science:

    • Medical Imaging
    • Image Processing
    • Magnetic Resonance Imaging (MRI)

    Background:

    • MR image synthesis allows retrospective contrast optimization.
    • It involves computing N(H), T1, and T2 images from source data.
    • Synthesized images are generated using computed images and selected timing parameters.

    Purpose of the Study:

    • To investigate design considerations for a digital image processor for rapid MR image synthesis.
    • To examine the feasibility of performing image synthesis computations in high-speed hardware.

    Main Methods:

    • Identified computations required for MR image synthesis.
    • Analyzed the feasibility of high-speed hardware implementation.
    • Evaluated bit-limited calculation precision and error bounds.
