Optical Projection Tomography (OPT), the optical equivalent of x-ray computed tomography, reconstructs the 3D structure of a sample from a series of wide-field 2D projections acquired at different angles [1]. OPT is used to map the optical attenuation and/or fluorescence distributions of intact transparent samples without the need for mechanical sectioning. While it is typically applied to chemically cleared samples, it can also be used to image inherently transparent or weakly scattering live organisms including adult zebrafish up to ~1cm in diameter [2]. When applying OPT to live samples it is important to minimise the data acquisition time while maximising the image quality in the presence of scattering. The former issue can be addressed using compressive sensing to reduce the number of projections required [3]. Scattered light can be rejected using structured illumination [4], but this removes emission from regions the excitation modulation does not reach and reduces the available dynamic range. To address this, we have explored the rejection of scattered light by acquiring projections with parallel semi-confocal line illumination and detection in an approach we describe as slice-OPT (sl-OPT). The impact of optical scattering can also be reduced by imaging at longer wavelengths [5]. We are exploring OPT in the NIR 1&2 spectral windows. However, exotic array detectors, e.g. for short wave infrared light, are costly and so we are also developing a single pixel camera [6] approach. We will present our progress applying these techniques to 3D imaging of vasculature and tumour burden in live adult zebrafish. [1] Sharpe et al, Science, vol. 296, Issue 5567, pp. 541-545, 2002.

Optical Projection Tomography (OPT) is a wide-field technique for measuring the threedimensional distribution of absorbing/fluorescing species in non-scattering (optically cleared) samples up to ~1cm in size, and as such is the optical analogue of X-ray computed tomography. We have extended the intensity-based OPT technique to measure the three-dimensional fluorescence lifetime distribution (tomoFLIM) in transparent samples. Due to its inherent ratiometric nature, fluorescence lifetime measurements are robust against intensity-based artifacts as well as producing a quantitative measure of the fluorescence signal, making it particularly suited to Förster Resonance Energy Transfer (FRET) measurements. We implement tomoFLIM via OPT by acquiring a series of wide-field time-gated images at different relative time delays with respect to a train of excitation pulses for a range of projection angles. For each time delay, the three-dimensional time-gated intensity distribution is reconstructed using a filtered back projection algorithm and the fluorescence lifetime is subsequently determined for each reconstructed horizontal plane by iterative fitting of an appropriate decay model. We present a tomographic reconstruction of a fluorescence lifetime resolved FRET calcium contruct, TN-L15 cytosol suspension, in a silicone phantom. This genetically encoded sensor, TN-L15, comprises the calcium-binding domain of Troponin C, flanked by the fluorophores cyan fluorescent protein and citrine. In the presence of calcium ions TN-L15 changes conformation bringing the two fluorophores into close proximity, resulting in FRET. We also present autofluorescence and fluorescently labelled tomoFLIM reconstructions of chick embryos, including a genetically encoded fluorophore TagRFP-T. The fluorophore was electroporated in ovo into the neural tube of the embryos, which were subsequently dissected two days post-electroporation, fixed in ethanol and optically cleared for OPT/tomoFLIM acquisition. The reconstructed 3-D fluorescence lifetime image provides contrast between the genetically labelled TagRFP-T and the emitted autofluorescence.
