  • Within a 2D slice, however, isodose lines can be drawn through points of equal dose to characterize the dose distributions within a single plane.
  • isodose line

Examples

  • He therefore underwent treatment with single-dose stereotactic irradiation delivered by a linear accelerator with 1,200 cGy prescribed to the 90% isodose line.

    Academic text (2008)
  • In radiology, an isodose line helps doctors visualize areas receiving the same radiation dose during treatment planning.

  • The 80-gray isodose line (1 Gy = 1 J/kg) surrounding this region shows that the region received a dose of 80 Gy or higher.

    Academic text (2002)
  • The treatment plan included an isodose curve, indicating where the radiation levels are consistent across the affected area.

  • During the simulation, the isodose map clearly illustrated which tissues were exposed to similar doses of radiation.

Surface Forms

isodose singular
isodoses plural

Morphology

isodose = dose (semi-transparent) = iso + dose

Formed with the scientific combining form 'iso-' meaning 'equal' plus 'dose'; the technical prefix may not be familiar to general learners though the relation to 'dose' is clear in context.

Etymology

Isodose comes from iso- 'equal' and dose 'amount', so an isodose is a line or area on a chart that shows where the radiation amount is the same.
