Advanced quantitative evaluation of PET systems using the ACR phantom and NiftyPET software.

ABSTRACT:

Purpose

A novel phantom-imaging platform, a set of software tools, for automated and high-precision imaging of the American College of Radiology (ACR) positron emission tomography (PET) phantom for PET/magnetic resonance (PET/MR) and PET/computed tomography (PET/CT) systems is proposed.

Methods

The key feature of this platform is the vector graphics design that facilitates the automated measurement of the knife-edge response function and hence image resolution, using composite volume of interest templates in a 0.5 mm resolution grid applied to all inserts of the phantom. Furthermore, the proposed platform enables the generation of an accurate μ$\mu$ -map for PET/MR systems with a robust alignment based on two-stage image registration using specifically designed PET templates
