Data from: Optical projection tomography implemented for accessibility and low cost (OPTImAL)

Optical projection tomography (OPT) is a 3D mesoscopic imaging modality
that can utilise absorption or fluorescence contrast and is widely applied
to fixed and live samples in the mm-cm scale. We present OPTImAL, an
open-source research-grade implementation of modular OPT hardware and
software that has been designed to be widely accessible by using low-cost
components, including LED excitation and cooled CMOS cameras. Both the
hardware and software are modular and flexible in their implementation,
enabling rapid switching between sample size scales and supporting
compressive sensing to reconstruct images from undersampled sparse OPT
data, e.g., to facilitate rapid imaging with low
photobleaching/phototoxicity. We also explore a simple implementation of
focal scanning OPT to achieve higher resolution, which entails the use of
a fan-beam geometry reconstruction method to account for variation in
magnification.
