• Added decubitus orientation and related changes. (#285) @darcymason
• Fix a bug if Pixel Data attribute was set for non image based SOP Classes (i.e. RT Structure Set). (#214) @cutright

dvhcalc

• Implement interpolation for non square pixels in DVH calculation. (#124)
• Fix a bug where the DVHDoseScaling attribute was not applied properly to RT Dose DVHs. (#301) @cvelten
• Fix a bug where floating point pixel spacing wasn't rounded in DVH calculations. (#318) @smichi23

dose

• Added RT Dose grid summmation with interpolation (from DVHA). (#164) @cutright

dicomparser

• Initial implementation of memory mapped access to pixel data. (#131)
• Ensure that all files read have a valid File Meta header.

New Contributors

• @cutright made their first contribution in #164
• @darcymason made their first contribution in #170
• @smichi23 made their first contribution in #318
• @cvelten made their first contribution in #301

Full Changelog: v0.5.5...v0.5.6

v0.5.5

dvhcalc

• Refactored bounding & resampling set up code to only execute if conditions are met.
• Fix a bug where the resampled LUT was not calculated correctly for DVH interpolation.

dvh

• Differential DVH calculation modified. (#60) [Hideki Nakamoto]

v0.5.4

dvhcalc

• Implemented DVH interpolation. (#39)
• Implemented optional user-specified structure thickness
  for DVH calculation.

dvh

• Fix a bug in absolute_volume if a DVH instance's volume units
  don't use default of Gy.
• Fix a bug in absolute_dose if a DVH instance's dose units don't
  use default of Gy. (#19)
• Support decimal values for volume constraints (i.e.V71.6).
• Support decimal values for dose constraints (i.e. D0.03cc).

dicomparser

• Ensure that Rx Dose from RT Plan is rounded instead of
  truncated.
• Account for holes and bifurcated structures for structure
  volume calculation.
• Implement structure volume calculation using Shapely. (#28)

v0.5.3

• Support DVH calculation of structures partially covered by the dose grid.

v0.5.2 - All things DVH

• Added DVH class for Pythonic access to dose volume histogram data.
• Refactored and added unit tests for dvhcalc.
• Added examples and usage for dvh and dvhcalc modules.
• Jupyter notebook of examples can be found in Binder:

v0.5.1

• Added support for pydicom 0.9.9 so releases from PyPI can be built.

v0.5.0

Initial release with dicomparser support for Python 2/3 and pydicom 1.0.
