3-D printed kidney phantoms aid nuclear medicine dosing calibration

December 5, 2016

In nuclear medicine, the goal is to keep radiation exposure at a minimum, while obtaining quality images. Optimal dosing for individual patients can be difficult to determine. That's where 3D-printed organ models of varying size and shape could be of great use.

In a study reported in the December issue of The Journal of Nuclear Medicine, researchers at the University of Würzburg in Würzburg, Germany, demonstrated that low-cost 3D printing technology can be used for clinical prototyping. Johannes Tran-Gia, PhD, the study's corresponding author, explains: "This research shows a way of producing inexpensive models of patient-specific organs/lesions for providing direct and patient-specific calibration constants. This is particularly important for imaging systems suffering from poor spatial resolution and ill-defined quantification, such as SPECT/CT."
