  1. PSI2CAD Interface Jürgen Salk University of Ulm Germany

  2. Features • ANSI C • runs on command line • platform independent i/o routines, i.e. runs on Intel x86 (Windows, Linux, little endian) via SAMBA/NFS and on PA -RISC (HP-UX, big endian) • implemented as plugin for CadPlan GUI (by means of korn-shell wrapper script)

  3. Features (cont´d) • Online help (-h Option) • Verbose mode (-v option) to trace problems • Trim dose matrix to body contour (-t Option) • Automatically checks for valid filenames • Easy installation and simple usage • It´s small

  4. Commandline options

  5. Usage as CadPlan pluginStep 1 • Add a new plan • Add dummy field • Select resolution of dose matrix

  6. Usage as CadPlan pluginStep 2 • Store selected parameters as new plan

  7. Usage as CadPlan pluginStep 3 • Run psi2cad as User Command from the Tools pulldown menu

  8. Usage as CadPlan pluginStep 4 • Check messages displayed in info box

  9. Usage as CadPlan pluginStep 5 • Reload plan for imported dose matrix

  10. Usage as CadPlan plugin • Once imported to CadPlan the externally calculated plan can be reviewed like any other locally calculated treatment plan

  11. Compare plans by images

  12. Compare plans by images (cont´d)

  13. Compare plans by images (cont´d)

  14. Compare plans by dose volume histograms

  15. Compare plans by dose volume histograms(cont´d)

  16. 3D reconstructions

  17. Resolution issues • The CadPlan dose grid is fixed to a maximum number of 160112 grid points, i.e. the maximum size of the dose matrix depends on the grid spacing • Reduction of grid spacing (e.g. from 2.5 mm to 1.25 mm) may lead to incomplete coverage of the regions of interest

  18. Resolution issues (cont´d) • If necessary redefine the center of the calculation area to cover regions of interest

  19. Resolution issues (cont´d) • Store the new grid spacing/calculation area as a new plan

  20. Resolution issues (cont´d) • Perform steps 3-5 as described above to import the externally calculated dose matrix with high resolution grid spacing. • psi2cad will automatically detect the new grid and offset of the calculation area

  21. Have fun. ;-)
