Cinematic Rendering in Anatomy: A Crossover Study Comparing a Novel 3D Reconstruction Technique to Conventional Computed Tomography
AbstractIntegration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two ‐dimensional grey scale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two‐period crosso ver study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and com...

Coordinate-based fast lightweight path search algorithm for electromagnetic navigation bronchoscopy
AbstractElectromagnetic navigation bronchoscopy (ENB) uses electromagnetic positioning technology to guide the bronchoscope to accurately and quickly reach the lesion along the planned path. However, enormous data in high-resolution lung computed tomography (CT) and the complex structure of multilevel branching bronchial tree make fast path search challenging for path planning. We propose a coordinate-based fast lightweight path search (CPS) algorithm for ENB. First, the centerline is extracted from the bronchial tree by applying topological thinning. Then, Euclidean-distance-based coordinate search is applied. The centerl...

MLF-IOSC: Multi-Level Fusion Network With Independent Operation Search Cell for Low-Dose CT Denoising
Computed tomography (CT) is widely used in clinical medicine, and low-dose CT (LDCT) has become popular to reduce potential patient harm during CT acquisition. However, LDCT aggravates the problem of noise and artifacts in CT images, increasing diagnosis difficulty. Through deep learning, denoising CT images by artificial neural network has aroused great interest for medical imaging and has been hugely successful. We propose a framework to achieve excellent LDCT noise reduction using independent operation search cells, inspired by neural architecture search, and introduce the Laplacian to further improve image quality. Emp...

Take away body parts! an investigation into the use of 3D ‐printed anatomical models in undergraduate anatomy education
In conclusion, 3D‐printed anatomical models can be successfully produced from the CT data set of a recently deceased donor. These models can be used in anatomy education as a teaching tool in their own right, as well as a method for augmenting the curriculum and complementing established learning modalities, such as dissection‐based teaching.

Development, implementation, and results of a  simulation-based hands-on brachytherapy workshop for medical students
ConclusionThe simulation-based medical education course for multicatheter brachytherapy can improve self-assessed technical competence. Residency programs should provide resources for this essential component of radiation oncology. This course is exemplary for the development of innovative practical and competence-based teaching formats to meet the current reforms in medical education.

Creating vascular models by postprocessing computed tomography angiography images: a guide for anatomical education
ConclusionsThe early adopters in education and clinical practices have embraced the medical imaging-guided 3D printed anatomical models for their ability to provide tactile feedback and a superior appreciation of visuospatial relationship between the anatomical structures. Printed vascular models are used to assist in preoperative planning, develop intraoperative guidance tools, and to teach patients surgical trainees in surgical practice.

The Effectiveness of Using 3D Reconstruction Software for Surgery to Augment Surgical Education
Conclusions3D-reconstruction software could be a viable tool to augment radiology education within a surgery residency, especially in CT interpretation, but there appears to be a minimum threshold of knowledge needed for meaningful improvement; therefore, this software may be more useful for PGY3-5 residents than PGY1-2 residents.

M3NAS: Multi-Scale and Multi-Level Memory-Efficient Neural Architecture Search for Low-Dose CT Denoising
Lowering the radiation dose in computed tomography (CT) can greatly reduce the potential risk to public health. However, the reconstructed images from dose-reduced CT or low-dose CT (LDCT) suffer from severe noise which compromises the subsequent diagnosis and analysis. Recently, convolutional neural networks have achieved promising results in removing noise from LDCT images. The network architectures that are used are either handcrafted or built on top of conventional networks such as ResNet and U-Net. Recent advances in neural network architecture search (NAS) have shown that the network architecture has a dramatic effec...

Automated Anatomic Labeling Architecture for Content Discovery in Medical Imaging Repositories
AbstractThe combination of textual data with visual features is known to enhance medical image search capabilities. However, the most advanced imaging archives today only index the studies ’ available meta-data, often containing limited amounts of clinically useful information. This work proposes an anatomic labeling architecture, integrated with an open source archive software, for improved multimodal content discovery in real-world medical imaging repositories. The proposed soluti on includes a technical specification for classifiers in an extensible medical imaging archive, a classification database for querying over ...

Longitudinal retention of anatomical knowledge in second ‐year medical students
The Radboud University Medical Center has a problem‐based, learner‐oriented, horizontally, and vertically integrated medical curriculum. Anatomists and clinicians have noticed students’ decreasing anatomical knowledge and the disability to apply knowledge in diagnostic reasoning and problem solving. In a longitudinal cohort, the retention of anatomical knowledge gained during the first year of medical school among second‐year medical students was assessed. In May 2011, 346 medical students applied for the second‐year gastro‐intestinal (GI) tract course. The students were asked to participate in a reexamination ...

The objective of this study is to shed light on the role of YouTube in lung cancer screening in terms of guidelines, screening options, target population, steps after screening, and risks and benefits of screening. We searchedYouTube.com™ to identify videos dealing with lung screening using the keywords: lung cancer screening. Videos without sound, uploaded before 2009, longer than 20 min, duplicate videos, and videos in a language other than English were excluded. This method yielded 123 videos that fit criteria. Videos were cod ed for inclusion of LC screening process, risks and benefits of screening, screening guideli...
