The 1990s brought progress from chamfer matching to voxel intensity, and it ushered in the idea that intensity relationships between images could be non-linear, hinting at the concept of a more general dependence between images.

Last time, we took a brief stroll through the timeline of radiology to take a look at the relationship between the evolution of imaging technologies and corresponding development in medical image registration. Digital radiology took root with the clinical introduction of CT in 1971, and despite the introduction of clinical MRI in 1980, it wasn’t until PET came of age in the early 1990s that the utility of image registration became plainly evident. Today we’ll dig into a couple of the early algorithms.

Have you ever wondered how far we’ve come in image registration technology? It wasn’t always the case that 3D deformable registration could be fully automated. This week, we’re throwing it back to 1895, when medical imaging started, then we’ll go back to the future to see how medical image registration evolved.

Today we’re lifting the curtain on the machine perception technology behind Autofuse, and showing how it works step by step in a complicated head and neck case and a pediatric spine growth case using scans taken 31 months apart! We also provide a glimpse of the future of patient-specific QA for deformable registration, and how Autofuse technology can be used to monitor how radiation treatment to the spine affects vertebral body growth in children.
