pylinac 0.6.0.6

Version 0.6.0

on Python PyPI

V 0.6.0 6/17/15

General

• Pylinac now has a wheel variation. Installation should thus be quicker for users with Python 3.4.

• Most main module classes now have a save method to save the image that is plotted by the plot method.

  Class-based Constructors

• This release presents a normalized and new way of loading and initializing classes for the PicketFence, Starshot, VMAT and CBCT classes.
  Those classes all now accept the image path (folder path for CBCT) in the initialization method. Loading other types of data
  should be delegated to class-based constructors (e.g. to load a zip file into the CBCT class, one would use
  cbct = CBCT.from_zip_file('zfiles.zip')). This allows the user to both initialize and load the images/data
  in one step. Also prevents user from using methods before initialization (i.e. safer). See ReadTheDocs page for more info.

  Dependencies

• Because the VMAT module was reworked and is now based on Varian specs, the pandas package will no longer be required. FutureWarnings have been removed.

  CBCT

• Bug #18 is fixed. This bug did not account for slice thickness when determining the slice positions of the
  relevant slices.

• Bug #19 is fixed. This bug allowed the loading of images that did not belong to the same study. An error is now raised
  if such behavior is observed.

• Demo files are now read from the zipfile, rather than being extracted and then potentially cleaning up afterward. Behavior
  is now quicker and cleaner.

• Individual plots of certain module/slices can now be done. Additionally, the MTF can be plotted.

• The user can now adjust the relative position of the slice locations in the event the phantom is not set up to calibration
  conditions.

  Log Analyzer

• Keys in the txt attr dict weren't stripped and could have trailing spaces. Keys are now stripped.

  VMAT

• Ability to offset the segments has been added.
  Complete overhaul to conform to new Varian RapidArc QA specs. This includes the following:

• Rather than individual samples, 4 or 7 segments are created, 5x100mm each.

• Deviation is now calculated for each segment, based on the average segment value.

• The DRMLC test has changed name to MLCS. E.g. passing a test should be: myvmat.analyze('mlcs'), not myvmat.analyze('drmlc'); the latter will still work but raises a future warning.

  Starshot

• Fixed a bug where an image that did not have pixels/mm information would error out.

• Added a tolerance parameter to the analyze method.
