“…DICOM data 283 axial images were uploaded into the Amira® object pool with the final model in the graphic window. DICOM data was reconstructed using a combination of surface rendering, volume rendering and semi-autocombined rendering [6,7]. One purpose of the study is to provide clinical trainees better visualization of the subject's clinical anatomy in the face to study the interventional approach to the trigeminal ganglion, especially structures around the foramen ovale.…”

Trigeminal ganglion injection is a common procedure for many facial pain syndromes, including trigeminal neuralgia. The procedure is usually done under fluoroscopy guidance to target at the foramen ovale where lies the trigeminal ganglion and the mandibular branch of trigeminal nerve exits. In this project, Amira® software was used to create 3D structures that can be visualized stereoscopically and involve the structures to study the procedure pathway. The detailed anatomical structures include the skin, skull, external and internal pterygoid muscle, masseter muscle, buccinator muscle, external carotidartery and its branches, internal carotid artery and its branches, vertebral artery, trigeminal ganglion and its branches, internal jugular vein, and parotid gland were created. The structures’ relationships and potential complications are described. The 3D model is used to guide and educate students about safe procedure pathways and may potentially be used to evaluate and modify procedures scientifically.

Human nasal airflow in a healthy and partially blocked cavities is investigated using computational and experimental means. While previous studies focused on the flow inside the nasal cavity, this study also looks at the external air stream coming out of the nostrils. The aim is to investigate the airflow subject to partial blocking in the nasal cavity and assess the potential of using a flow visualization method to identify abnormal nasal geometry. Two methods of study are used: Computational Fluid Dynamics (CFD) and experiment based on Particle Image Velocimetry (PIV). Nasal cavity geometry is reconstructed from CT scans. The flow visualization Schileren method is also demonstrated. The computational results agree well with the previous results in terms of Nasal Resistance (NR) and character of the internal flow. Good agreement is also found in the external aerodynamics during expiration between the computational and experimental results. Several generic partial blockages are investigated to show changes in NR, turbulence energy and the air stream leaving the nostrils during expiration. Anterior blockages are found to have more profound effects on all these three aspects, but all show effects on the external air stream. A possible universal angle for the external air stream emitted by a healthy nasal cavity is discussed.

“…This sometimes leads to what is termed the "uncanny valley": a near-perfect rendering of a human face or expression that is eerily off. [13][14][15] Medical illustration and diagnostic imaging may at first seem opposing and competing disciplines. Rather than facing a choice between a medical artist's rendition and a faithful reproduction, however, we propose that these two fields can collaborate to improve the diagnostic and didactic values of both.…”

Combination of volume‐rendering 3D surface modeling and medical illustration to capture the living fetus

Objective A good medical illustration renders essential aspects of a procedure or condition faithfully, yet idealizes it enough to make it widely applicable. Unfortunately, the live fetus is generally hidden from sight, and illustrating it relies either on autopsy material or manipulated newborn images. High‐definition volume rendering of diagnostic imaging data can represent hidden conditions with an almost lifelike realism but is limited by the resolution and artifacts of the data capture. We have combined both approaches to enhance the accuracy and didactic value of illustrations of fetal conditions. Methods Three examples, of increasing complexity, are presented to demonstrate the creation of medical illustrations of the fetus based on semiautomatic computerized posthoc manipulation of diagnostic images. Results The end product utilizes the diagnostic accuracy of ultrasound and magnetic resonance imaging of the fetuses and the spatial manipulation of 3D models to create a lifelike, accurate and informative image of the fetal anomalies. Conclusion Volume‐rendering and 3D surface modeling can be combined with medical illustration to create realistic and informative images of the developing fetus, using a level of detail that is tailored to the intended audience.
