Fig. 7. Transverse CT scan slices through the Tribodus limae braincase. Orbital region. A, slice 187, at the level of the optic nerve; B, slice 209, at the level of the oculomotor nerve; C, slice 216, at the level of the oculomotor nerve showing the anterior semicircular canal originating anterior to the postorbital process; D, E, slices 222 and 226, respectively, at the level of the efferent pseudobranchial foramen and the foramen for the superficial ophthalmic complex and profundus nerve; F, slice 239, at the level of the utricular recess and abducens foramen; G, H, slices 241 and 242, respectively, showing the course of the superficial ophthalmic complex and abducens nerve within the cartilage of the orbit.

Dataset with results of "Joint 2D to 3D image registration workflow for comparing multiple slice photographs and CT scans of apple fruit with internal disorders"
<p><strong>Summary</strong></p> <p>This dataset contains all results from the paper "Joint 2D to 3D image registration workflow for comparing multiple slice photographs and CT scans of apple fruit with internal disorders". Most notably, this dataset contains the corresponding CT slices for slice photographs of 1347 'Kanzi' apples. This dataset also contains data of the results section, metadata required to make the registration code run, and segmentation masks of the apple slice photographs. The "raw" data that was used to produce these results can be found in another Zenodo dataset: <a href="../record/8167285">https://zenodo.org/record/8167285</a>.</p> <p><br><strong>Description</strong></p> <ul> <li><strong>registered ct photo side-by-side view.zip </strong>is the easiest way to explore the registered CT photo image pairs. For every apple slice it contains a .png image consisting of the slice photo, registered CT slice and a combined view (photo=green, CT=purple) side-by-side. The resolution was reduced to reduce the file size.</li> <li><strong>registered ct slices.zip </strong>contains the full resolution CT slices as .tiff files. The matching slice photos can be found in <strong>slice_photos_crop.zip</strong> in <a href="../record/8167285">https://zenodo.org/record/8167285</a>.</li> <li><strong>photo metadata.zip </strong>contains all metadata files required to run the code on <a href="https://github.com/D1rk123/apple_photo_ct_workflow">https://github.com/D1rk123/apple_photo_ct_workflow</a>.</li> <li><strong>results.zip</strong> contains the IPCED annotations and per apple metrics that were used to calculate all the average metrics and tables in the results section of the paper.</li> <li><strong>subset experiment registered annotation slice.zip </strong>contains the full resolution CT slices of the annotation slice in the subset experiment as .tiff files.</li> <li><strong>segmentation masks.zip </strong>contains slice photo segmentation masks as .png images. There are subfolders for the training set, the test set and the masks used for the workflow in the paper.</li> </ul> <p><br><strong>Research group</strong><br>This dataset was produced by the Computational Imaging group at Centrum Wiskunde & Informatica (CI-CWI) in Amsterdam, The Netherlands: <a href="https://www.cwi.nl/research/groups/computational-imaging">https://www.cwi.nl/research/groups/computational-imaging</a></p> <p><strong>Contact details</strong><br>dirk [dot] schut [at] cwi [dot] nl</p> <p><strong>Acknowledgments</strong><br>This work was funded by the Dutch Research Council (NWO) through the UTOPIA project (ENWSS.2018.003).</p>
VSDFullBodyBoneReconstruction: Segmentations and surface models of bones of the entire lower body created from cadaver CT scans from the VSDFullBody collection
<p>The segmentations and models of the bones of the lower extremities were created from anonymized postmortem CT scans of the whole body originally published by Michael Kistler in the Swiss Institute for Computer Assisted Surgery Medical Image Repository (<a href="https://www.smir.ch/">smir.ch</a>) as open access Virtual Skeleton Database (VSD). A mirror of the VSD is available at Zenodo: <a href="https://doi.org/10.5281/zenodo.8270364">10.5281/zenodo.8270364</a>. </p><p><strong>However</strong>, this is a stand-alone upload and the full VSD is not required to use this upload. Further information can be found in the following publication:</p><p>Fischer, M. C. M. Database of segmentations and surface models of bones of the entire lower body created from cadaver CT scans. <i>Sci.

The use of the MAT files is explained by examples for MATLAB and Python in the Git repository.</p><p><strong>Usage</strong><br>The CT volume data, segmentations, reconstructions and raw PLY mesh files of each subject are linked by a project file (MRML scene file) that can be opened with the open-source medical imaging software 3D Slicer (<a href="https://www.slicer.org/">slicer.org</a>).</p>
