Abstract: One embodiment is a unique method employing an improved image resolution recovery technique. Another embodiment is a unique system implementing an improved image resolution recovery technique. A further embodiment is a method including obtaining a sinogram based upon a measurement of an imaging system, processing the sinogram using a smoothing or fitting technique, deconvolving a system response function of the imaging system from the sinogram to provide a deconvolved sinogram, and constructing an image based upon the deconvolved sinogram. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings.

Abstract: This application generally relates to the field of medical imaging. According to certain embodiments, anatomically accurate phantoms with tunable activity concentrations and x-ray attenuation coefficients for use in positron emission tomography and positron emission tomography/x-ray computed tomography are created by utilizing a three dimensional printer. According to certain embodiments, radiolabeled or x-ray contrast material is added to a binder used in a three dimensional printer, and the resultant radiolabeled or x-ray contrast binder is selectively used to bind a prototype powder into an accurate scanning rendition of a selected portion of anatomy. By utilizing one or more radiolabeled or x-ray contrast binders, multiple tissue densities can be present in a single phantom, with complex geometries rendered therein.
