Design and measurement of 3D-printed variable-morphology and variable-density breast phantoms for mammography and breast CT dose assessment [PDF]
3D Printing in MedicineAccurate dose quantification across radiation-based breast imaging techniques is important for patient safety, but currently available phantoms do not easily allow the assessment of the impact of breast size and density across modalities. Here we design,
