Step map
Instead of relying on a single generic AI model, this pipeline connects specialized tools to maximize quality. First, you'll use nnU-Net to clean, standardized volumetric data ready for segmentation input. Then, you pass the output to BasicAI to high-quality labeled dataset (ground truth) for training or validation. Then, you pass the output to nnU-Net to training configuration ready with model, loss, and augmentation defined. Then, you pass the output to nnU-Net to trained model with documented performance metrics (dice, hausdorff distance). Then, you pass the output to Zebra Medical Vision to segmented label maps for all input volumes, saved as nifti or dicom-seg. Finally, nnU-Net is used to validated segmentation quality with quantitative metrics and clinical sign-off.
Acquire and preprocess imaging data
Clean, standardized volumetric data ready for segmentation input
Define segmentation protocol and annotate ground truth
High-quality labeled dataset (ground truth) for training or validation
Select and configure segmentation model
Training configuration ready with model, loss, and augmentation defined
Train and validate segmentation model
Trained model with documented performance metrics (Dice, Hausdorff distance)
Run inference on new images
Segmented label maps for all input volumes, saved as NIfTI or DICOM-SEG
Evaluate and refine segmentation quality
Validated segmentation quality with quantitative metrics and clinical sign-off
Collect DICOM or NIfTI files from the source (PACS, scanner, or public dataset). Normalize pixel intensities, resample to isotropic voxel spacing, and crop or pad to a consistent size. Apply bias field correction if using MRI.
Why nnU-Net: nnU-Net provides medical image preprocessing as a core feature, directly matching the step's need for preprocessing imaging data.
Specify the anatomical structures or pathology to segment (e.g., liver, tumor, lung lobes). Use a semi-automated tool or manual contouring to create reference labels on a representative subset of slices, following clinical guidelines.
Why BasicAI: BasicAI offers image annotation, which is directly needed for ground truth annotation in medical segmentation.
Choose a deep learning architecture (e.g., U-Net, nnU-Net, or Transformer-based) based on modality and organ complexity. Set hyperparameters: patch size, batch size, loss function (Dice + cross-entropy), and data augmentation strategy.
Why nnU-Net: nnU-Net is a segmentation model that includes automatic hyperparameter tuning and medical image preprocessing, fitting the need to select and configure a segmentation model.
Split annotated data into training (70%), validation (15%), and test (15%) sets. Train the model using the configured pipeline, monitor Dice score and loss on validation set, and save the best checkpoint. Use cross-validation if dataset is small.
Why nnU-Net: nnU-Net supports training and validation of segmentation models with built-in preprocessing and tuning, aligning with the step's requirements.
Load the trained model and apply it to unseen medical images using a sliding window or patch-based approach. Overlap patches and average predictions to reduce boundary artifacts. Post-process with conditional random fields (CRF) or morphological operations to smooth edges.
Why Zebra Medical Vision: Zebra Medical Vision performs inference on medical images for disease detection, which can be adapted for segmentation inference.
Compare automated segmentation against ground truth (if available) using Dice, Jaccard, and Hausdorff distance. For clinical deployment, have a radiologist review a random sample of outputs. Iterate by retraining with additional annotated edge cases.
Why nnU-Net: nnU-Net includes evaluation capabilities through its training and validation pipeline, relevant for refining segmentation quality.
§ Before you start
Teams or solo builders working on science & healthcare tasks who want a repeatable process instead of one-off tool experiments.
No. Start with the top pick for each step, then replace tools only if they do not fit your pricing, compliance, or output needs.
Open the mapped task page and compare top options side by side. Prioritize output quality, integration fit, and predictable cost before scaling.
