X-ray induced acoustic computed tomography

open access: yesPhotoacoustics, 2020
X-ray imaging has proved invaluable in medical diagnoses and non-destructive testing (NDT) in the past century. However, there remain two major limitations: radiation harm and inaccessibility to the sample.

X-ray Fluorescence Computed Tomography (XFCT) Imaging with a Superfine Pencil Beam X-ray Source

open access: yesPhotonics, 2021
X-ray fluorescence computed tomography (XFCT) is a molecular imaging technique that can be used to sense different elements or nanoparticle (NP) agents inside deep samples or tissues. However, XFCT has not been a popular molecular imaging tool because it

Potential of ultra-high-resolution photon-counting CT of bone metastases: initial experiences in breast cancer patients

open access: yesnpj Breast Cancer, 2021
Conventional CT scanners use energy-integrating detectors (EIDs). Photon-counting detector (PCD) computed tomography (CT) utilizes a CT detector technology based on smaller detector pixels capable of counting single photons and in addition discriminating

Algorithms for joint activity–attenuation estimation from positron emission tomography scatter

open access: yesEJNMMI Physics, 2019
Background Attenuation correction in positron emission tomography remains challenging in the absence of measured transmission data. Scattered emission data may contribute missing information, but quantitative scatter-to-attenuation (S2A) reconstruction ...
