[IGSTK-Developers] Presentation at SDMS

[Ziv Yaniv]

Hi Kevin,

Very nice paper.

I mainly liked the distinction you make between "software safety" and 
"system safety" (summary of section 4.3). IGSTK will indeed be a safe 
software once all state machines are fully populated and we've done all 
the testing. This definitely doesn't guarantee a safe navigation system.

On windows it is not out of the question that another process will 
commandeer the CPU so that the screen doesn't change exactly at the same
time as the physician moves the tool. It is up to the physician to 
notice that the UI has frozen, as IGSTK will not be able to check that 
the transformation times have expired.

We should make it crystal clear to IGSTK users that while we have safety 
as our highest priority ("safety" appears 52 times in the book) we 
provide "software safety" and not "system safety". It is their 
responsibility to provide the "system safety".

                          regards
                              Ziv
