3D model-specific heart holder for optimal positioning during CT scanning. a The CT table was segmented and exported as an STL file at the time of model segmentation and creation. b A custom table adaptor piece created in CAD software was designed to sit flush with the CT Table. c The corresponding heart model was imported into CAD software, and 4 cylinders were created and positioned so that they intersected the model and the table adaptor piece. d Holes fitted to the cylinders with 0.1 mm offset were created in the model, and the table adaptor piece and the cylinders were shortened to the appropriate length. e Example of finished model-specific heart holder in CAD software. f 3D printed heart and heart holder positioned in the CT gantry in the same orientation that the patient was scanned in (feet first)
