INTRODUCTION: We aimed to assess the feasibility of determining Alzheimer's disease cerebrospinal fluid (CSF) cut points in small samples through comparison with amyloid positron emission tomography (PET).METHODS: Twenty-three individuals (19 patients, four controls) had CSF measures of amyloid beta...

Global image registration using a symmetric block-matching approach.

Journal of medical imaging (Bellingham, Wash.)

Modat M, Cash DM, Daga P, Winston GP, Duncan JS, Ourselin S.
PMID: 26158035

Microfocus CT (micro-CT) is an imaging method that provides three-dimensional digital data sets with comparable resolution to light microscopy. Although it has traditionally been used for non-destructive testing in engineering, aerospace industries and in preclinical animal studies, new applications...

Opt Express. 2020 Jul 06;28(14):20978-20991. doi: 10.1364/OE.396734.

Image transmission through multimode optical fibers has been an area of immense interests driven by the demand for miniature endoscopes in biomedicine and higher speed and capacity in telecommunications. Conventionally, a complex-valued transmission matrix is obtained experimentally to link...
