With a total of eight patents to his name, Metzger has developed innovative methods that enhance the quality and efficiency of magnetic resonance imaging (MRI).

Latest Patents

One of Metzger's latest patents is titled "Slice ordering for MB-EPI ASL imaging." This invention presents a method for generating a perfusion-weighted image using arterial spin labeling (ASL) with segmented acquisitions. The process involves dividing an anatomical area of interest into multiple slices and performing a multi-band echo planar imaging (EPI) acquisition using an MRI system. This method allows for the acquisition of a control image dataset representative of the slices, utilizing a central-to-peripheral or peripheral-to-central slice acquisition order. Following a post-labeling delay, the MB EPI acquisition process generates a labeled image dataset, which is then used to create a perfusion-weighted image by subtracting the labeled dataset from the control dataset.

Another notable patent is "Automated co-registration of prostate MRI data." This invention focuses on medical imaging analysis systems that utilize automatic image registration algorithms for three-dimensional (3D) co-registration of MRI data. The system employs mutual information as a similarity metric to compute registration parameters for volumes of interest (VOIs) within the imaging series. The apparatus includes a computer-readable storage medium and a processor that identifies and registers the VOIs, enhancing the accuracy of MRI data analysis.
