Comparison of algorithms for converting 3D objects into rolls, using a spiral coordinate system

Virtual and Physical Prototyping, 2017
The definition of a point’s location in volume by Cartesian, spherical and cylindrical coordinate systems requires three dimensions (x, y, z), (r, θ, ϕ) and (ρ, ϕ, z) accordingly.

Towards the production of radiotherapy treatment shells on 3D printers using data derived from DICOM CT and MRI: preclinical feasibility studies [PDF]

, 2015
Background: Immobilisation for patients undergoing brain or head and neck radiotherapy is achieved using perspex or thermoplastic devices that require direct moulding to patient anatomy. The mould room visit can be distressing for patients and the shells
