Sinogram based analysis of the acquired dataset. (A) AIP at 0° and relative difference after a full 360° rotation. The bidirectional drift of the sample during the measurements is visible on the bottom of panel A, and implies a misaligned AIP-sinogram. (B) Original sinogram of the SPIM-AIP measurements as a function of the angle, the color code that labels the Y-axis depth is the same as in panel A. It is worth noticing that the color of the sinogram turns toward blue-red at the end of the rotation, which means that the spheroid is slightly moving towards the bottom of the FEP tube. (C) Cropped sinogram around the spheroid used to reduce the size of the reconstructed volume. It is worth noticing how the data is completely misaligned. (D) Aligned autocorrelation sinogram calculated by using the data from the sinogram in (C). The alignment of the dataset is achieved by simply calculating the autocorrelation for each AIP projection and stacking of the projections one after the other.
