OpenMIP in Action
Raw medical images often suffer from noise, inconsistencies, and large file sizes, making them unsuitable for direct application in deep learning algorithms. Current preprocessing is often task-specific and lacks a unified approach, hindering AI development.
MRI scans require specific preprocessing steps due to their unique characteristics. This includes Bias Field Correction (using N4ITK) to address magnetic field inhomogeneities and Standardization (using Nyul method) to ensure comparable intensity values across scans, crucial for AI consistency.
CT scans necessitate Hounsfield Units (HU) Transformation to standardize radio density measurements, followed by Organ Windowing to enhance contrast for specific regions of interest. These steps prepare CT data for accurate AI analysis.

Nonparametric Nonuniform Intensity Normalization for Bias Correction
Case Study: Accelerated Cancer Detection
A medical research institution utilized OpenMIP to preprocess a large dataset of MRI scans for prostate cancer detection. By automating bias field correction, standardization, and segmentation, they reduced preprocessing time by 60% and observed a 15% increase in their deep learning model's accuracy, leading to faster and more reliable diagnostic support. The standardized data facilitated easier collaboration and model transferability.
