Voxel 3D printing, 3DP Phantoms for Radiotherapy

In this issue of “From Academia”, we included two publications that connect the world of radiology and medical 3D printing in very creative ways. In the first article, the authors use an ultrasonic elastography technique that measures the effective density and the dynamic bulk modulus elastography (EBME) of 3D printed anatomical models using voxelated materials and 3D printed by J750. This could have important implications for future quality control of 3D printed medical devices using the voxel print technique. In the second article, The researchers demonstrated an inexpensive method of reproducing a full spectrum of adult bone-like anthropomorphic femur phantom slab using a new interlace deposition extrusion method of standard PLA and Fe-PLA filaments. This model can achieve the required CT appearance (based on HU) for a range of bony structures and soft tissues while providing patient-specificity. Such phantom has applications in surgical guidance, diagnostic imaging, as well as end-to-end dosimetry in radiotherapy.

“From Academia” features recent, relevant, close to commercialization academic publications. Subjects include but not limited to healthcare 3D printing, 3D bioprinting, and related emerging technologies.
