Confocal and micro-CT data of Glyphonotum hsiaoi, holotype, NIGP200729

<p>This dataset contains the raw confocal laser scanning microscopy (CLSM) slices and X-ray microtomography (micro-CT) slices for the holotype of <em>Glyphonotum hsiaoi</em> (NIGP200729) from mid-Cretaceous Burmese amber. This dataset is associated with the publication "An enigmatic Cretaceous beetle in Kachin amber with tentative affinities to Pythidae (Coleoptera: Tenebrionoidea)" (DOI:10.1002/ece3.70615).<br>&nbsp;<br>Confocal images were obtained with a Zeiss LSM710 confocal laser scanning microscope, using the 561 nm (DPSS 561-10) laser excitation line. The original CZI files are provided, which could be opened by the ZEISS ZEN software.<br>&nbsp;<br>Micro-CT data were obtained with a Zeiss Xradia 520 Versa 3D X-ray microscope. Scanning parameters were as follows: isotropic voxel size, 2.6143 &mu;m; power, 3 W; acceleration voltage, 40 kV; exposure time, 4 s; projections, 3001. The TIFF stack is provided.</p>

Generalizable cone beam CT esophagus segmentation using physics-based data augmentation

<p>This upload contains open source AAPM thoracic auto-segmentation data (http://aapmchallenges.cloudapp.net/competitions/3) augmented with physics-based data augmentation technique introduced in this paper:https://iopscience.iop.org/article/10.1088/1361-6560/abe2eb .</p> <p>The original data contained thoracic planning CT along with organs-at-risk segmentation masks for Esophagus, heart, lungs and spinal cord. The physics-based augmentation pipeline was used to convert planning CT images to pseudoCBCT (psCBCT) images which are routinely used in weekly radiotherapy treatment sessions for cancer patients. Further geometric data augmentations are also applied to convert one planning CT/OAR dataset into 23 perfectly paired CT/psCBCT/OAR pairs.</p> <p>This dataset has been used to train deep learning models for organs-at-risk segmentation from psCBCT images and multitask simultaneous CBCT to CT translation and segmentation tasks.</p>

FastText embeddings obtained from SNOMED CT - Spanish and International

<p>FastText model trained in a corpus that was obtained from SNOMED CT by performing random walks. There are three models: one trained using all relations available in the international version of SNOMED CT, another one trained using only is_a relations from the international version of SNOMED and the last one is trained using all relations from the Spanish version of SNOMED CT. This was developed for the end project of the Master Degree in Artificial Intelligence in the Universidad Polit&eacute;cnica de Madrid.

MRI versus CT in the detection of brain lesions in patients with infective endocarditis before/after cardiac surgery

<p>Imaging of brain involvement in infective endocarditis can drive the clinical management of this serious condition. MRI is very sensitive, but CT is more readily available. In this retrospective study, we compared the detection rate of CT and MRI.</p> <p>After Ethics Committee approval, we retrospectively reviewed a series of 20 patients (13 males, median age 64 years) who underwent both CT and MRI before or after cardiac surgery for definite infective endocarditis. Unenhanced CT and MRI were evaluated for acute ischemic lesions, both punctuate and large, intraparenchymal hemorrhages, cerebral microbleeds, subarachnoid hemorrhages, abscesses, microabscesses and meningitis. Qualitative and Cohen &kappa; analysis were performed. The value of contrast-enhanced scans (MRI, <em>n</em> = 14; CT, <em>n</em> = 9) and cognitive status were also assessed.</p> <p>While CT rapidly excludes large hemorrhages before cardiac surgery for infective endocarditis, MRI accurately distinguishes the whole spectrum of brain lesions.</p>

CT data for: Insight into the evolutionary assemblage of cranial kinesis from a Cretaceous bird

<p><span>The independent movements and flexibility of various parts of the skull, called cranial kinesis, is an evolutionary innovation that is found in living vertebrates only in some squamates and crown birds and is considered to be a major factor underpinning much of the enormous phenotypic and ecological diversity of living birds, the most diverse group of extant amniotes. Compared to the postcranium, our understanding of the evolutionary assemblage of the characteristic modern bird skull has been hampered by sparse fossil records of early cranial materials, with competing hypotheses regarding the evolutionary development of cranial kinesis among early members of the avialans. Here, a detailed three-dimensional reconstruction of the skull of the Early Cretaceous enantiornithine <em>Yuanchuavis kompsosoura</em> allows for its in-depth description, including elements that are poorly known among early diverging avialans but are central to deciphering the mosaic assembly of features required for modern avian cranial kinesis. Our reconstruction of the skull shows evolutionary and functional conservation of the temporal and palatal regions by retaining the ancestral theropod dinosaurian configuration within the skull of this otherwise derived and volant bird. Geometric morphometric analysis of the palatine suggests that loss of the jugal process represents the first step in the structural modifications of this element leading to the kinetic crown bird condition. The mixture of plesiomorphic temporal and palatal structures together with a derived avialan rostrum and postcranial skeleton encapsulated in <em>Yuanchuavis</em> manifests the key role of evolutionary mosaicism and experimentation in early bird diversification.</span></p>

HaN-Seg: The head and neck organ-at-risk CT & MR segmentation dataset

<p><strong>The HaN-Seg: Head and Neck Organ-at-Risk CT &amp; MR Segmentation Dataset</strong> is a publicly available dataset of anonymized head and neck (HaN) images of 42 patients that underwent both CT and T1-weighted MR imaging for the purpose of image-guided radiotherapy planning. In addition, the dataset also contains reference segmentations of 30 organs-at-risk (OARs) for CT images in the form of binary segmentation masks, which were obtained by curating manual pixel-wise expert image annotations.
