In this panel you may customized your startup preferences for common parameters including: prescribed dose, the default isotope seed and plaque, isodose colors, user defined points of interest, auto-save interval, recent patient tracking, alert conditions, the default size of 2D dose matrices and which matrices to calculate automatically.
NOTE: Most controls in PS will display tooltips explaining their use if you hover the cursor over the control.
The controls in the Dosimetry group select the surfaces, histograms, actions and default dose matix size associated with the Calculate 2D Matrices menu item and convenience buttons found throughout the program.
The controls in the Isodose labels group are default settings affecting the spatial distribution and proximity tolerance of isodose line labels. There are slider controls in the 2D and retinal dosimetry windows that allow you to easily override these startup preferences.
The controls in the Misc. group affect and enable various user interface behaviors. For the most part these parameters are used in software development but you are free to customize these behaviors if you feel a need.
