Application of Fractal Dimension for Quantifying Noise Texture in Computed Tomography Images [PDF]
, 2018 Purpose Evaluation of noise texture information in CT images is important for assessing image quality. Noise texture is often quantified by the noise power spectrum (NPS), which requires numerous image realizations to estimate.

Design and CT imaging of casper, an anthropomorphic breathing thorax phantom
Biomedical Physics & Engineering Express, 2023 Abstract The goal of this work was to build an anthropomorphic thorax phantom capable of breathing motion with materials mimicking human tissues in x-ray imaging applications. The thorax phantom, named Casper, was composed of resin (body), foam (lungs), glow polyactic acid (bones) and natural polyactic acid (tumours placed in the lungs).

Design of an Anthropomorphic Respiratory Phantom for PET Imaging [PDF]
, 2020 Purpose Respiratory motion during positron emission tomography (PET) scans can be a major detriment to image quality in oncological imaging, leading to loss of quantification accuracy and false negative findings. The impact of motion on lesion quantification and detectability can be assessed using anthropomorphic phantoms with realistic anatomy ...
