Version 5.42beta 4/22/10

Many new Eye Physics prototype plaques for adults and infants (infant plaques are designated as RB series) are now hard coded.
The anterior portion of prototype plaques can be curved to fit an oblate spheroid.
Full 3D tesselation of complex plaque surfaces including concave faces and collimating slots (earlier versions of PS only tesselated the back convex surface of the plaques.)
More detailed ray-tracing calculation of plaque and slot collimation within the plaque.
More detailed 2D cross sections through the plaques including interior surfaces and seeds.
Improved and fixed various bugs related to interactive plaque design and editing. Most plaque design functions are now available as fully interactive windows rather than modal dialogs.
Plaques can be scaled and exported to a rapid prototyping printer as .dxf or .stl files.
Added calculation of a Dose Surface Histogram (DSH) for the retina (from fovea to the ora serrata) surface and tumor base as an optional alternative to the DVH. This enables quantitative comparison of treatment plans with the goal of reducing dose to normal retina while maintaining tumor coverage.
Improved calculation and display of the dosimetric effect of the anterior air boundry based on published monte carlo calculations by Thomson et al. 2008.
Improved T(r) curve for calculating the attenuating effects of the COMS silastic carrier for I-125 and Pd-103 based on monte carlo studies of Thomson et al. for the AAPM TG129 report.
New set of physics files prepared with updated T(r) and dose reduction curves as a function of distance from an air boundry, distance from the plaque, and position of the plaque on the eye.
Support for a coronal CT image. As a result, some buttons in the imaging window have been rearranged.
Angle indicator added to CT ruler.
Inventory files can contain any number of items instead of exactly 25 items.
In the radionuclide inventory list window, inventory items in the current active plaque are now highlighted in red.
Slightly revised the built-in defaults for the standard adult eye model.
Added a new built-in standard infant eye model.
Eye size defaults can now be customized and saved as preferences.
Location of ora serrata can be customized.
Retina posterior to the ora serrata can be tinted in the 2D eye cross-sections.
Fixed a problem loading certain BEBIG plaque files reported by user in Spain.
Revised the method of calculating tumor area to a 2D polar projection solution. This robust method allows for tumors of arbitrary shape and crossed edges and also determines the % of the retina (as delimited by the ora) covered by the tumor. The older spherical polygon method remains available by menu selection for comparison of the methods.
Standard tumor models now default to 36 edges instead of 24 and can be adjusted from 6 to 360 edges.
Improved fitting of plaques and anterior tumors to oblate spheroid.
Misc obscure user interface and bug fixes.
Tested with MacOS 10.6 (Snow Leopard).

Plaque Simulator now has a custom installer to simplify new installations and updates. After downloading a new PS version, simply run the included PSInstall.app. The installer will create or update files on your system (using current versions found in the PS folder of the installer package). You can still install files manually if you wish.
Added automatic calculation and display of complete suture coordinates on the eye (clock hour and distance from limbus) for each eyelet.
Suture points beneath each eyelet are projected onto on the scleral surface in 3D view.
Added ability to name suture eyelets.

Previous versions of PS only supported the TG43 anisotropy function at r = 1 cm. Additional TG43 anisotropy factors for r = 0.5 and 2.0 cm are now supported. PS will now interpolate the anisotropy function across the range 0.5 < r < 2 cm. For r <= 0.5 cm the data for r = 0.5 is used, for r >= 2.0 cm the r = 2 cm data is used.
Applicable physics files (I-125 models 6702,6711,2301,3631,S06,12501 and Pd-103 models 200 and 3633) updated to TG43U1
Added ability to override automatic plan file name generation.
Fixed a bug where a tumor could move slightly due to rounding errors when repeatedly rentering the std tumor dialog.
Fixed a bug re enabling profile #7 from the BEBIG Ru plaque calibration dialog.
Date input controls in modal dialogs did not update to reflect keyboard text input when exiting the dialog if the control text field (e.g. day of month) still had the keyboard focus. These controls are now forced to update when closing a dialog.
Experimental support added to model air bubbles located between the seeds and sclera. Please do not use this mode for patient planning at this time.
Fixed a bug re updating retina dose in the 3D setup window after changing between plaques.
Added ability to control seed display on retinal diagrams.
Fixed bugs which degraded performance by repeatedly updating some windows and controls when it was not necessary.

Fixed a bug in which the orange background color of an item in the central axis dose table closest to the COMS 5mm point was improperly colored if the point was 5mm inset from any surface of the eye. The orange color is now used only if the point is 5mm inset from the inner surface of the sclera and also 6 mm from the plaque surface on the central axis.

User interface, appearance, controls, labels & menu tweaks.

Version 5.22 12/11/03

Fixed the preferences dialog to enable multiple dose matrices by default on new installs.
Fixed a potential crashing bug that could occur if multiple matrices has been disabled (in the preferences) in order to save memory on older computers and you then attempt to open a current patient setup file which always contains multiple (4) dose matrices. The additional matrix parameters now simply overwrite the single dose matrix parameters.
User interface & menu tweaks.

Version 5.21 12/09/03

Added in-place editing of individual isodose values in the isodose legend. The isodose window legend is now an array of static text controls. Clicking on an item in the leftmost column changes it to an editable text field. Enter the new value for that isodose. Use return key to accept new value, the Enter key to accept and advance to the next item, the tab and up/down arrow keys move the keyboard focus to the next item. Click outside the control to remove keyboard focus and/or bring up the custom isodose dialog.
Iodose color buttons are now true controls.
