3D-printed Medical Imaging Phantoms
replicate Human Anatomy

A joint research effort by Siemens and Stratasys
has demonstrated a highly accurate 3D-printed
medical imaging system that uses phantoms to
replicate human anatomy.
The system uses Stratasys’ RadioMatrix materials and
Digital Anatomy technology combined with Siemens
Healthineers’ advanced algorithms to significantly
improve the quality of complex anatomical medical
imaging phantoms, allowing surgeons, researchers
and educators to replace simplistic anatomical
phantom models for pre-surgery planning and
education.
MEDICAL FOCUS In particular these anatomically accurate, patient
specific 3D-printed phantoms are scalable and
efficient in developing new CT scan algorithms,
enabling hospitals and imaging centres to enhance
the calibration and performance of CT scanners.
Variances as low as single Hounsfield units were
reported between real and printed models in critical
areas such as veins and grey matter.
