- Cinematic Rendering: The Reality in Clinical Practice
- Robust rendering technique across multiple body regions ranging from head to feet
- Excellent for demonstration of skin, muscle, soft tissues, bone, vasculature
- Complex trapizoids can allow for multiple tissue types to be displayed in a single visualization - Cinematic Rendering: The Reality in Clinical Practice
- Preset values of specific anatomic values can be used in most cases to speed up the generation of the 3D image dataset
- Preset values may change depending on the specific visualization (anterior vs lateral view) and the scan protocol used (IV contrast and injection rate and acquisition timing such as arterial/venous/delayed phase imaging) - Cinematic Rendering: The Reality in Clinical Practice
- AI may prove to be of value in choosing the best (or a series of potential best) image displays based on the dataset used.
- For example could the system provide a series of select “preset views” to image a suspected pancreatic mass based on learning from previously generated datasets? - Cinematic Rendering: The Reality in Clinical Practice
- Visualization of cinematic rendered images can be done with select images or with the creation of a video file. Video files have the advantage over static images especially for the referring physician who may not have access to the workstation
- Newer display technologies like Microsoft HoloLens 2 may enhance the value of cinematic rendering - HoloLens 2

J Digital Imaging (in press) - "Selective removal of bones enhances 3D volume-rendered viewing of surfaces, particularly in joint articulations.The information provided from surface viewing is valuable for both diagnosis and presurgical planning in the setting of arthropathy and fracture."

J Digital Imaging (in press) - "Whereas editing with IWT is an efficient method of improving the diagnostic capacity of 3D-rendered imaging,errors can still arise when vessels are located in close proximity to bone."
