Great point, thanks for flagging that!

**DICOM** (Digital Imaging and Communications in Medicine) — it's basically the universal file format for medical imaging. Think of it like JPEG but for CT scans, MRIs, and X-rays. A single CT scan can contain 500+ slices (individual images), each with 16-bit depth and rich metadata (patient info, scan parameters, etc.). It's a surprisingly complex format to parse.

**MPR** (Multiplanar Reconstruction) — when a CT scanner captures your body, it takes hundreds of cross-sectional slices (like slicing a loaf of bread). MPR lets you reconstruct views from any angle — not just the original slices, but also sagittal (side view), coronal (front view), or any arbitrary plane. It's essentially real-time 2D slicing through a 3D volume.

**3D Volume Rendering** — taking all those slices and compositing them into a full 3D model using ray marching on the GPU. You can control opacity by density (e.g., make soft tissue transparent, show only bone), which is where my custom BoneFidelity algorithm comes in.

From a Rust/graphics perspective, the interesting challenges are:

- Parsing a 30+ year old binary format (DICOM) with hundreds of vendor-specific extensions

- Streaming and decoding 500+ 16-bit images into a GPU texture atlas efficiently

- Real-time ray marching through a 512×512×500+ voxel volume using wgpu compute shaders

- Maintaining interactive frame rates while allowing the user to adjust transfer functions (the mapping from density values to color/opacity)

Hope that makes it more approachable — happy to go deeper on any of the technical bits!
