Project Description

Prostate biopsies can become a big challenge, especially when the prostate changed from pre-procedural to intra-procedural image acquisition. Motion and deformation of the prostate raises difficulties for positioning the biopsy needle at the right position. The registration module’s goal is to optimize the workflow and provide a solution, that is easy to use.

Objective	Approach and Plan	Progress and Next Steps
Slicer module implemented that allows the registration of the prostate Integrate the z-frame and navigation component into the module Use SliceTracker during prostate biopsies as a replacement to current approach	Present the module to interested members of the community Get feedback about the workflow and usability Work on the remaining issues Discuss about migrating this module into a slicelet	Positive feedback for workflow and usability of the module LumpNav is a slicelet example to follow Planning to create an extension from that module and provide an appropriate example dataset

Progress notes

• What about simply hiding components (toolbars) that are not needed?
• Trick to hide all toolbars!

>>> w = slicer.util.mainWindow()
>>> for c in w.children():
...   if str(type(c)).find('ToolBar')>0:
...     c.hide()

Drawback: after restarting Slicer, the toolbars are still hidden.
