I have a collection of DICOM CBCT volumes exported from Sirona GALILEOS / SIDEXIS and I need a 3D Slicer extension that streamlines research-grade periapical lesion analysis. The core priority is highly accurate detection and segmentation; everything else follows from that. The workflow I picture starts with frictionless DICOM import, passes the volumes through a pre-trained model for initial lesion detection, lets the user refine or approve the mask, and then automatically computes total lesion volume in mm³. Once a baseline study is finished, the same tool should accept a follow-up scan, register it to the baseline, and output comparable measurements so longitudinal change can be plotted immediately. Key deliverables • 3D Slicer extension (Python scripted module or C++ loadable, whichever integrates best) • Integration of a pre-trained deep learning network for periapical lesion suggestion • Interactive editing tools leveraging Slicer’s Segment Editor for quick correction • Automatic volume calculation and CSV export of all metrics • Saving of clean segmentation masks (NIfTI or labelmap) for later reuse • Side-by-side or overlaid comparison mode to track volume change between timepoints Acceptance criteria 1. On a provided test dataset the tool produces a lesion mask within clinically acceptable boundaries that needs ≤20 % manual correction. 2. Volume output matches manual ground-truth measurements within ±5 %. 3. Baseline vs follow-up report lists both absolute volume and percentage change. 4. Extension installs through Slicer’s Extension Manager on Windows and macOS without extra compilation steps. Time frame is ASAP, so reusable open-source libraries (MONAI, PyTorch, ITK-Snap bridges, etc.) are welcome if they shorten development while keeping accuracy high. I will supply annotated sample CBCT volumes, ground-truth segmentations, and any additional documentation you need once the project starts.

Hi, this project requires precise integration of medical imaging workflows with AI-driven segmentation, which aligns well with my experience extending complex software platforms and integrating deep learning models. The primary engineering challenge lies in robust orchestration of DICOM ingestion, model inference, and interactive segmentation refinement while maintaining clinical accuracy and usability. I usually structure such systems by separating the ingestion, inference, and user interaction layers, ensuring modularity and maintainability. My work on Custom Feature Development & Integration involved similar extension and integration tasks with a focus on clean, testable code. I also developed AI-driven content generation platforms that required automated processing pipelines combined with human-in-the-loop approval, which parallels the lesion mask refinement and volume calculation here. I approach these solutions with production-grade reliability in mind, incorporating fallback mechanisms and validation checks to ensure consistent output quality. I can start by outlining the DICOM import pipeline and sketching the segmentation and registration architecture for your review. Thanks, Hercules

I can help you. I will develop a Python-based 3D Slicer scripted module to ensure seamless cross-platform installation without compilation hurdles. My approach involves using a custom MONAI-based inference engine to pipe your model’s predictions directly into the Segment Editor, allowing for immediate manual refinement. For the longitudinal component, I will implement a registration workflow using Slicer’s BRAINSFit or Elastix modules to align follow-up scans to the baseline, enabling automated delta-volume calculations. All metrics will be extracted via the Segment Statistics API to ensure mm³ precision and formatted into a CSV export. This architecture prioritizes Slicer’s native DICOM database handling to keep the Sirona import process frictionless.

Hi, You need a 3D Slicer extension to automate the segmentation of periapical lesions in Sirona CBCT volumes, specifically enabling longitudinal volumetric analysis and clinical-grade reporting. I recently developed a pipeline for MRI reconstruction and deep learning-based pattern recognition, where I handled complex DICOM-to-NIfTI workflows and custom segmentation refinement. For your project, I propose using a **MONAI-based 3D U-Net architecture** optimized for small-lesion detection, integrated directly into Slicer via a Python scripted module. I have previously achieved a 92% dice overlap on medical imaging tasks and am confident in meeting your <20% manual correction threshold. My experience converting models to ONNX and deploying TFLite ensures your plugin will remain portable across Windows and macOS. Do you have the ground-truth segmentations stored as RT-Structs or raw labelmaps?

The Sirona GALILEOS DICOM format has metadata quirks that trip up standard parsers. I would build the pipeline in Python using SimpleITK for volume loading and a 3D UNet for lesion detection, wrapped as a 3D Slicer plugin. About 7 to 10 days depending on the number of lesion classes you need segmented. These numbers are based on the post as written. Once we walk through the full scope, including output format and volume count, both may adjust. I can start today. Want to jump on a quick call?

Hi there, This is Gene from Luxembourg. CBCT lesion segmentation usually breaks when preprocessing, voxel spacing normalization and registration are not tightly coupled with inference, leading to drift in longitudinal comparison. I would implement a Slicer scripted module that runs a unified pipeline from DICOM import to model inference, followed by correction in Segment Editor and consistent volume computation. I’d integrate a MONAI/PyTorch-based model with ITK registration and Slicer segmentation APIs to ensure stable baseline vs follow-up alignment and reproducible mm³ metrics. I’ve built complex real-time and data-heavy UI systems in LiveJasmin and Oranum where latency, consistency and interactive tooling were critical. Delivery: 4 days. What format is your pre-trained model currently in for deployment inside Slicer? I can start right away

Hello, As a result of a detailed review of your project requirements, I fully understand the need for a 3D Slicer extension focused on accurate CBCT lesion detection, segmentation, and longitudinal measurement. I have experience building medical imaging, computer vision, and AI-assisted analysis workflows and I'm available to start immediately. I bring strong expertise in Python, C++, 3D Slicer module development, MONAI/PyTorch, DICOM/CBCT processing, image registration, segmentation, and medical image analysis with over 10 years of experience. One of the key challenges here is integrating the model cleanly into Slicer while preserving voxel spacing, mask accuracy, volume calculation in mm³, and baseline/follow-up registration consistency. I can build a Slicer extension with DICOM import, AI mask suggestion, Segment Editor refinement, volume metrics, CSV export, NIfTI/labelmap saving, and overlay comparison for percentage change tracking. I have a couple of quick questions. • Do you already have a preferred pre-trained lesion model, or should model selection/fine-tuning be included? • Should the first version be a Python scripted module to speed up delivery and simplify Windows/macOS installation? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos

Automating CBCT lesion segmentation with a 3D Slicer extension that actually ships and works clinically requires tight integration between the deep learning pipeline, the segmentation editing layer, and the volume measurement output. I've architected and delivered production AI systems end-to-end, from model integration through to user-facing results, in regulated-adjacent environments where accuracy requirements are non-negotiable. My most recent production system ingests live operational data mid-query, retrieves grounded citations from a knowledgebase, and returns structured answers; the challenge of ensuring model output stays within acceptable accuracy bounds while remaining editable by non-technical users maps directly to your lesion mask refinement workflow. I hold the Microsoft Azure AI Engineer Associate cert, which means I understand token budgets, model inference constraints, and pipeline integration patterns that matter when deploying deep learning in an application context. For this project I would build the Slicer extension as a Python scripted module, wire it to your pre-trained lesion detection model, and implement the Segment Editor integration so users can correct masks before final volume computation, then export the baseline-versus-followup comparison metrics to CSV. A concrete question that will shape the approach: does the pre-trained model output per-lesion instance masks or a single binary mask per volume? This determines whether the volume reporting layer needs to handle multi-region segmentation or a single region.
