System and Method for Temporal Fidelity Enhanced Medical Imaging Using Temporal Deconvolution

摘要

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.

1. A method for increasing a temporal fidelity of a series of image frames obtained with a medical imaging system, the steps of the method comprising:
a) acquiring a series of image frames depicting a time-varying image contrast in a subject using the medical imaging system; b) selecting a window function that is representative of a temporal fidelity window; c) producing another series of image frames having an increased temporal fidelity to the time-varying image contrast as compared to the series of image frames acquired in step a) by performing a temporal deconvolution on the series of image frames acquired in step a) using the window function selected in step b).
