This code system http://terminology.hl7.org/CodeSystem/radiotherapy defines the following codes:

CodeDisplayDefinition
LDR-PERM Low Dose Rate Brachytherapy - Permanent PlacementRadiation treatment that irradiates a body volume with permanently placed radiation sources delivering low dose rates (typically less than or equal to 2 Gy/hour).
LDR-TEMP Low Dose Rate Brachytherapy - Temporary PlacementRadiation treatment that irradiates a body volume with temporarily placed radiation sources delivering low dose rates (typically less than or equal to 2 Gy/hour).
3D Three DimensionalDose calculated with projection onto 3D imaging (e.g., CT or MR) delivered with either static aperture (Collimator, SRS Cone, Static MLC, blocks, etc) or non-IMRT/VMAT dynamic apertures (e.g., field-in-field, dynamic arc) using either single gantry angles or arcs.
PPS Particle Passive ScatteringIn proton or carbon ion beam therapy, a technique where the beam is spread out to larger dimension using a scattering device such as lead foil.
PSS Particle Spot ScanningIn proton or carbon ion beam therapy, a technique where accelerated particles are focused into a small beam and then moved (scanned) over target regions in the patient.
MIX MixedBoth photon and particle based beams are used to deliver the radiation therapy.
CAV-IMB Intracavitary, Intensity ModulatedA technique of brachytherapy that dynamically directs the radiation into the tumours and away from healthy tissue, for example, by incorporation of metallic shields inside brachytherapy applicators.
