Characterizing geometric distortions of 3D sequences in clinical head MRI
Magnetic Resonance Materials in Physics, Biology and Medicine, 2022 Abstract Objective Phantoms are often used to estimate the geometric accuracy in magnetic resonance imaging (MRI). However, the distortions may differ between anatomical and phantom images. This study aimed to investigate the applicability of a phantom-based and a test-subject-based method in evaluating geometric ...

Aberration correction in diagnostic ultrasound: A review of the prior field and current directions
Zeitschrift für Medizinische Physik, 2023 Medical ultrasound images are reconstructed with simplifying assumptions on wave propagation, with one of the most prominent assumptions being that the imaging medium is composed of a constant sound speed.

A hybrid 3-D reconstruction/registration algorithm for correction of head motion in emission tomography [PDF]
, 2002 Even with head restraint, small head movements can occur during data acquisition in emission tomography that are sufficiently large to result in detectable artifacts in the final reconstruction.

Electrocardiogram Baseline Wander Suppression Based on the Combination of Morphological and Wavelet Transformation Based Filtering [PDF]
, 2019 One of the major noise components in electrocardiogram (ECG) is the baseline wander (BW). Effective methods for suppressing BW include the wavelet-based (WT) and the mathematical morphological filtering-based (MMF)algorithms.
