Dear Advanced Visualization Insider,
In the course of a couple years, 3D printing has become as indispensable as the internet. But one problem still drains the time and energy of the people producing 3D printed models -- the errors that occur when CT data are sent to stereolithography (STL) files to print.
According to a group from Germany, many errors requiring time-consuming correction can be traced to automated segmentation of 3D image data caused by regions of CT attenuation that don't correspond to the tissue type they depict. Fortunately, the study team has a solution, though it's a little old fashioned, as you'll see here.
Moving south to the tibia, researchers from the Netherlands have come upon a new way to plan for lower limb alignment surgery. Their C-arm-based augmented reality technique offers mechanical axis deviation measurements that are accurate and fast, with the bonus feature of requiring far lower radiation doses than the current fluoroscopy-based technique. Get the rest of the story here.
And speaking of low doses, a Swiss group found that routinely adding computer-aided detection (CAD) to lung cancer screening with ultralow-dose CT boosts the number of nodules detected -- potentially improving patient care for screening subjects who undergo multiple scans. How did the results compare to standard low-dose CT with CAD? Find out by clicking here.
If you haven't looked at 3D/4D ultrasound lately, you've missed a world of improvements that are transforming care in a wide variety of settings. Reconstruction in multiple image planes is making new details noticeable. Identification, positioning, and volume quantification are all improved with the use of 3D, and different anatomic structures can be seen more accurately in context with each other.
