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.
Chest CT Alone In, Fourteen Abnormality Overlays Out Without the Report
IGRA anchors each chest-CT abnormality instance to its report finding during training, then drops every text component at inference. Hang the volume, get multi-label overlays for 14 ReXGroundingCT categories in one forward pass. arXiv:2609.00447.
PET, CT, and the Report In: Tumor Overlay Without Dense Attention Blowup
CoMLP fuses head-and-neck PET/CT (and the clinical report) with cooperatively gated MLPs so modalities meet at full resolution before downsampling. Primary tumor and node overlays without pairwise attention matrices. arXiv:2609.04781.
Loose Box Prompt In, Prostate Overlay Out on Speckle Micro-Ultrasound
Approximate box on a 29 MHz micro-US slice in. Frozen MedSAM plus CLAHE, dilation, and Fourier contour smoothing hang a training-free prostate overlay for PSAD or biopsy registration. Point clicks fail on speckle. arXiv:2608.14796.
Pediatric CXR Model Ranks Abroad, Frozen Threshold Barely Fires
Guangzhou-trained pediatric pneumonia AI keeps usable AUROC in Bangladesh and Vietnam, but the locked source threshold drops sensitivity to 6.2% and 0%. Recalibration restores alerts at a steep false-positive cost. arXiv:2609.05140.
Corrupted Slice Interval In, Neighbor-Repaired T1 Stack Out
Flag a bad axial band on a T1 brain volume. SliceBridge reconstructs those slices from intact neighbors with coupled rectified flow and hangs the repaired interval back. arXiv:2609.01827.
Text Instruction In, Color Overlay Out on the Polyp or Skin Frame
Hang a polyp or skin lesion frame with a short text instruction. InstEditSeg edits the frame with latent diffusion and returns a color-coded overlay on the original pixels. arXiv:2609.02004.
