    15 de jun. de 2024 · Multiplanar reformation or reconstruction (MPR) involves the process of converting data from an imaging modality acquired in a certain plane, usually axial, into another plane 1. It is most commonly performed with thin-slice data from volumetric CT in the axial plane, but it may be accomplished with scanning in any plane and whichever modality ...

    Hace 6 días · When I drop them into Resolve, they scale correctly, and I can cut them right in - but I'm getting a too much aliasing on diagonal edges. I switched the sequence to UHD, and looked at the composites- no aliasing, looks great. Is there a trick for down scaling without aliasing?

    24 de jun. de 2024 · Image aliasing is a pervasive issue in digital imaging caused by under-sampling or inappropriate handling of high-frequency image details. While eliminating aliasing might not always be feasible, you can significantly reduce its impact by understanding the core concepts and mitigation techniques.
