Method and apparatus for measuring 3D geometric distortion in MRI and CT images with a 3D physical phantom

3D printing in MRI-compatible plastic resin has been used to fabricate and implement a geometric distortion phantom for MRI and CT imaging. The sparse grid structure provides a rigid and accurate phantom with identifiable intersections that are larger than the supporting members, which produces images that are amenable to fully automated quantitative analysis using morphometric erosion, greyscale segmentation and centroiding. This approach produces a 3D vector map of geometric distortion that is useful in clinical applications where geometric accuracy is important, either in routine quality assurance or as a component of distortion correction utilities.

System and method for temporal fidelity enhanced medical imaging using temporal deconvolution

A method for increasing the temporal fidelity, increasing the temporal sampling density, and/or reducing the temporal noise of a series of image frames obtained with a medical imaging system is provided. The image frames are acquired with the medical imaging system. The medical imaging system may be, for example, an x-ray C-arm imaging system. A window function that is representative of a temporal fidelity window is selected and used to temporally deconvolve the image frames using a minimization technique. A temporal sampling density may also be selected and used in the temporal deconvolution. The resultant deconvolved image frames have a higher temporal fidelity to a time-varying image contrast depicted in the acquired image frames, and may also have an increased temporal sampling density and/or reduced temporal noise.

Internal body marker prediction from surface data in medical imaging

Machine learning is used to train a network to predict the location of an internal body marker from surface data.
