Aberration correction in diagnostic ultrasound: A review of the prior field and current directions [PDF]
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.

Aberration correction in abdominal histotripsy [PDF]
International Journal of Hyperthermia, 2023 In transabdominal histotripsy, ultrasound pulses are focused into the body to noninvasively destroy soft tissues via cavitation. However, the ability to focus is limited by phase aberration, or decorrelation of the ultrasound pulses due to spatial ...

Aberration corrected emittance exchange [PDF]
Physical Review Special Topics - Accelerators and Beams, 2015 Full exploitation of emittance exchange (EEX) requires aberration-free performance of a complex imaging system including active radio-frequency (RF) elements which can add temporal distortions. We investigate the performance of an EEX line where the exchange occurs between two dimensions with normalized emittances which differ by multiple orders of ...

Aberration correction for low voltage optimized transmission electron microscopy [PDF]
MethodsX, 2018 Further development of low voltage electron microscopy leads to an aberration correction of the device in order to improve its spatial resolution. The integration of a corrector to a desktop transmission electron microscope with exclusively low-voltage ...

Soft-Tissue Aberration Correction for Histotripsy. [PDF]
IEEE Trans Ultrason Ferroelectr Freq Control, 2018 Acoustic aberrations caused by natural heterogeneities of biological soft tissue are a substantial problem for histotripsy, a therapeutic ultrasound technique that uses acoustic cavitation to mechanically fractionate and destroy unwanted target tissue without damaging surrounding tissue.

The Lattice Geometry of Walsh-Function-Based Adaptive Optics
Photonics, 2022 We show that there is an intrinsic link between the use of Walsh aberration modes in adaptive optics (AO) and the mathematics of lattices. The discrete and binary nature of these modes means that there are infinite combinations of Walsh mode coefficients
