Beyond mechanics: Maximum‐likelihood‐driven PET detector alignment calibration

Medical Physics, Volume 53, Issue 1, January 2026.
Abstract Background Accurate quantification is a cornerstone of positron‐emission tomography (PET), yet mechanical inaccuracies during detector assembly continue to undermine this goal. Deviations from intended design geometries arise due to factors such as manufacturing tolerances, mechanical stress, and cumulative errors during module installation ...

Exact, time‐dependent analytical equations for spiral trajectories and matching gradient and density‐correction waveforms

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 400-410, January 2026.
Abstract Purpose To analytically define a spiral waveform and trajectory that match the constraints of gradient frequency, slew rate, and amplitude. Theory and Methods Piecewise analytical solutions for gradient waveforms under the desired constraints are derived using the circle of an involute rather than an Archimedean spiral.

On the Stability Barrier of Hermite Type Discretizations of Advection Equations

Numerical Methods for Partial Differential Equations, Volume 42, Issue 1, January 2026.
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.
