Quantitative anatomy mimicking slice phantoms.

ABSTRACT:

Purpose

To present a reproducible methodology for building an anatomy mimicking phantom with targeted T₁ and T₂ contrast for use in quantitative magnetic resonance imaging.

Methods

We propose a reproducible method for creating high-resolution, quantitative slice phantoms. The phantoms are created using gels with different concentrations of NiCl₂ and MnCl₂ to achieve targeted T₁ and T₂ values. We describe a calibration method for accurately targeting anatomically realistic relaxation pairs. In addition, we developed a method of fabricating slice phantoms by extruding 3D printed walls on acrylic sheets. These procedures are combined to create a physical analog of the Brainweb digital phantom.
