1. What Makes a Case Eligible?
To ensure accurate segmentation, planning, and patient-specific output generation, each case must meet basic technical and anatomical requirements.
General Requirements
The relevant anatomy for the selected procedure must be clearly visible.
All key anatomical landmarks needed for planning must be included.
Imaging quality must allow reliable segmentation and 3D reconstruction.
If only part of the required anatomy is available, the system may still support partial planning, limited to the anatomy provided.
2. Imaging Requirements (CT)
For best results, CT scans should meet the following criteria:
Parameter | Requirement |
Slice Thickness | ≤ 1.5 mm |
Slice Spacing | ≤ 1.5 mm |
Pixel Spacing | ≤ 1.0 mm |
Motion Artifact | Minimal (patient should remain still) |
Metal Artifact | Manual STL segmentation recommended if present |
⚠️ Severe artifacts that obscure bone anatomy may result in case rejection.
3. Manual STL Segmentation (Optional)
You may upload manual STL segmentations instead of, or in addition to, CT-based segmentation.
Supported When:
Automated segmentation is not suitable
Metal artifacts are present
The case is for validation, training, or review purposes
STL Guidelines:
STL files must represent complete, clinically relevant anatomy
Files must follow CustoMED naming conventions
Each bone should be saved as one STL file
STL files must align correctly with the original CT orientation
Pre-implanted devices or artifacts should not be included (unless for review only)
4. Supported Case Scope
CustoMED supports cases that:
Match a supported indication in the platform
Are left or right sided (when applicable)
Include anatomy relevant to the selected procedure
Are submitted by authorized users
Support level depends on:
Selected indication
Available anatomy
Imaging quality
Case completeness
5. Unsupported or Rejected Cases
Cases may be rejected if they include:
Anatomy not supported by the selected indication
Severe imaging artifacts preventing segmentation
Large existing implants that obscure landmarks (e.g. revision cases)
Missing required anatomical coverage
Non-clinical or non-medical datasets
Rejected cases are not charged.
6. What Happens After Upload?
Once your case is submitted:
Data is anonymized locally in your browser before upload
The system processes the data
Segmentation is generated or reviewed
Required landmarks are detected
You review and approve (or reject) the case
⏱️ Manual segmentation or review by the CustoMED team is typically completed within 24 hours.
For urgent cases, please contact support.
7. Platform Outputs
After final approval, the platform may generate:
Anatomical Models
Procedure-focused anatomy models (.STL)
Full anatomy models (.STL), where applicable
Patient-Specific Outputs
Surgical guides (.STL), based on available anatomy
Additional indication-specific outputs
Case Documentation
A PDF case report including:
Planning summary
Measurements
Design details
Visual references
Available outputs depend on the indication and approved anatomy.
8. Case Charges Policy
Case Status | Charged |
Rejected by CustoMED (technical/incomplete) | ❌ No |
Cancelled or rejected by user before approval | ❌ No |
Validation or training cases | ❌ No |
Fully approved with generated outputs | ✅ Yes |
9. Clinical Responsibility & Intended Use
The CustoMED platform:
Does not provide diagnoses or treatment decisions
Does not replace clinical judgment
Is intended to support visualization, planning, and communication
All final decisions regarding:
Implant choice
Implant positioning
Surgical execution
must be made by a licensed healthcare professional, who remains fully responsible for patient care.
