Click One Lung Tumour Slice, Fix the Ones You Never Touched
LeCor meta-learns case adapters so each clinician click on a planning CT updates the lung tumour overlay on untouched slices, not only the session memory. arXiv:2609.09477.
Sparse FLAIR In, Fusion That Does Not Spoil the Overlay
CoReFuse-Med filters resampling junk on sparse T2/FLAIR in shallow layers and rebalances deep fusion so multi-modal brain overlays stay usable when naive fusion would otherwise lose to T1-only. arXiv:2609.10261.
When Medical Device Animation Wins vs Interactive Implant 3D
Implant manufacturers often choose between two strong formats for 3D on the web and at congress: a film-style rendered medical animation, and a manipulable interactive 3D embed of the commercial SKU (Stock Keeping Unit). We at PYCAD build the interactive embed side for marketing, med-ed, and sales enablement. Animation studios cover the directed film side. […]
CBCT Arch Cross-Sections and Panoramic Rebuild in a Web Viewer
Plain multiplanar reformats open a CBCT on axial, coronal, and sagittal planes. That is useful. It is not how most dental users want to read an arch. We have a dental DICOM viewer that treats the arch as the control surface: you set a curve along the mandible or maxilla, get a panoramic-style rebuild from […]
Free OHIF Is the Silent Objection
When a medical device OEM asks us at PYCAD about a custom DICOM viewer, someone in the room usually brings up OHIF. Sometimes they name another strong open radiology viewer in the same breath. The question underneath is the same: why pay for specialty work if a free viewer already opens CT, MRI, and CBCT […]
Mandibular Canal From CBCT: Segmentation → STL → Web Overlay
I get asked about mandibular canal work more than almost any other dental structure. Teams want the canal labeled on CBCT, turned into a mesh, and shown with the scan in a browser. That path is clear: CBCT → labels → surface → overlay. This post walks that path only. How the stages fit together, […]
Server-Side vs In-Browser DICOM: How We Choose the Rendering Path
When a team asks us to build a custom DICOM viewer, the first engineering fork is not the UI. It is where the heavy rendering runs: in the browser (VTK.js) or on a server (Trame / VTK). We pick that path from constraints, not from preference. This post is how we decide on real builds. […]
How Implant Manufacturers Market Cages and Screws Better Than a PDF
Most implant product pages still look the same: a hero photo, a short feature list, and a PDF size table. That package works for catalog codes and sterile pack info. It fails when a surgeon or buyer needs to understand the device in space. At PYCAD we build interactive 3D for implant manufacturer marketing, med-ed, […]
Cancer Overlay In, Quiet Failure Flag Out From Internal Concepts
FOE hangs the tumor mask, then flags silent segmentation failures from Sparse Autoencoder concepts inside MedSAM, without rewriting the segmenter. Prostate MRI, pancreatic CT, brain MRI. arXiv:2609.08879.
T1 or T1ce In, Shared 106-Region Brain Overlay Out
SpFiLM conditions a 3D U-Net with spatial FiLM so one network parcellates plain T1 and post-gadolinium T1ce into 106 brain regions without a second adaptation stage. arXiv:2609.07718.
