When a patient's anatomy spills past the edge of a cone-beam CT detector, the reconstruction cups and streaks where the data ran out. A new conditional diffusion model restores those missing measurements in the raw projections, delivering markedly cleaner scans with no new hardware and...
Low dose means a noisy scan. A new class of deep-learning reconstruction rebuilds a clean, diagnostic cone-beam image from a fraction of the radiation — and asks us to read a picture the algorithm partly inferred....
A single vendor recently tallied two decades of dental-imaging patents - hundreds of filings, a couple hundred granted. Read as more than a press release, it is a map of how the dental image was engineered, invention by patient invention....
