Photo-Detectors for Time of Flight Positron Emission Tomography (ToF-PET) [PDF]
Sensors, 2010 We present the most recent advances in photo-detector design employed in time of flight positron emission tomography (ToF-PET). PET is a molecular imaging modality that collects pairs of coincident (temporally correlated) annihilation photons emitted ...

Deep learning-based time-of-flight (ToF) image enhancement of non-ToF PET scans. [PDF]
Eur J Nucl Med Mol Imaging, 2022 Abstract Purpose To improve the quantitative accuracy and diagnostic confidence of PET images reconstructed without time-of-flight (ToF) using deep learning models trained for ToF image enhancement (DL-ToF). Methods A total of 273 [18F]-FDG PET scans were used, including ...

Tandem Time-of-Flight (TOF/TOF) Mass Spectrometry and Proteomics [PDF]
Journal of the Mass Spectrometry Society of Japan, 2005 A dual reflectron tandem time-of-flight (TOF/TOF) mass spectrometer reported in 1993 gave rise to the invention and development of the curved-field reflectron (CFR) for focusing product ions. The CFR is used in this case as the second mass analyzer in a tandem instrument (based on the Kratos AXIMA CFR) in which the first mass analyzer is a linear TOF ...

Journal of Computer Networks and Communications, 2023 This article proposes the use of Wi-Fi ToF and a deep learning approach to build a cheap, practical, and highly-accurate IPS. To complement that, rather than using the classic geometrical approach (such as multilateration), it uses a more data-driven ...

Beyond Range: Innovating Fluorescence Microscopy
Remote Sensing, 2012 Time-of-Flight (ToF) technologies are developed mainly for range estimations in industrial applications or consumer products. Recently, it was realized that ToF sensors could also be used for the detection of fluorescence and of the minute changes in the

Machine-learning-enhanced time-of-flight mass spectrometry analysis
Patterns, 2021 Summary: Mass spectrometry is a widespread approach used to work out what the constituents of a material are. Atoms and molecules are removed from the material and collected, and subsequently, a critical step is to infer their correct identities based on

EDoF-ToF: extended depth of field time-of-flight imaging
Optics Express, 2021 Conventional continuous-wave amplitude-modulated time-of-flight (CWAM ToF) cameras suffer from a fundamental trade-off between light throughput and depth of field (DoF): a larger lens aperture allows more light collection but suffers from significantly lower DoF. However, both high light throughput, which increases signal-to-noise ratio, and a wide DoF,

Pulse Based Time-of-Flight Range Sensing
Sensors, 2018 Pulse-based Time-of-Flight (PB-ToF) cameras are an attractive alternative range imaging approach, compared to the widely commercialized Amplitude Modulated Continuous-Wave Time-of-Flight (AMCW-ToF) approach.
