Usage

The following rules apply to this value set:

  1. Select the most specific term appropriate for a given situation.
  2. Select the term that best describes the technique used, even if that term does not capture every detail of the technique. For example, image-guided intensity-modulated radiation therapy should be reported as IMRT because that category most closely aligns with the actual technique.

Valid combinations of modality and technique are described in the modality and technique extension [RadiotherapyModalityAndTechnique].

Code Descriptions

Common Usage Name Definition SNOMED CT Fully Specified Name SNOMED CT Concept ID
Two Dimensional Planning (2D) Dose calculated without projection onto 3D imaging and delivered without 3D techniques. Two dimensional external beam radiation therapy (procedure) 1156526006
Three Dimensional Planning (3D) Dose 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. Three dimensional external beam radiation therapy 1162782007
Intensity Modulated Radiation Therapy (IMRT) A technique of high-precision radiotherapy that uses computer control to deliver precise radiation doses that conform to a three-dimensional (3-D) shape by modulating the intensity of the radiation beam across the areas irradiated by each of the beams, with patterns designed under computer control to optimize the dose distribution according to a set of limits specified for target, organ at risk, and other structures. Intensity modulated radiation therapy (procedure) 441799006
Intraoperative Radiation Therapy (IORT) A radiation treatment administered during surgery. Radiotherapy - intraoperative control (procedure) 168524008
Neutron Capture Therapy (NCT) A technique where the patient is injected with a tumor-localizing drug containing a neutron absorber (boron-10), and then radiated with neutrons, which are captured, releasing high-energy alpha particles. Neutron capture therapy (procedure) 169317000
Particle Passive Scattering (PPS) In 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. External beam radiation therapy using particle passive scattering technique (procedure) 1156529004
Particle Spot Scanning (PSS) In 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. External beam radiation therapy using particle spot scanning technique (procedure) 1156528007
Volumetric Modulated Arc Therapy (VMAT) A type of IMRT technique where the radiotherapy machine rotates around the patient, radiating the target in a complete three-dimensional manner with variable speed and/or dose rate. Volumetric Modulated Arc Therapy (procedure) 1156530009

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
