Method: RTKIT::DoseDistribution#d

Defined in:
lib/rtkit/dose_distribution.rb

#d(percent) ⇒ Object

Calculates the dose that at least the specified percentage of the volume receives. Returns a dose (Float) in units of Gy.

Parameters

  • percent – Integer/Float. The percent of the volume which receives a dose higher than the returned dose.

Examples

# Calculate the near minimum dose (e.g. up to 2 % of the volume receives a dose less than this):
near_min = ptv_distribution.d(98)
# Calculate the near maximum dose (e.g. at most 2 % of the volume receives a dose higher than this):
near_max = ptv_distribution.d(2)

Raises:

  • (RangeError)
