Siemens Primus
Just a couple of shots with the cover off. I love these, I think I need to brush up my photography skills, or keep the Nikon camera with me. This is an older machine and Siemens has exited the radiotherapy business so you won't see them around much longer. Had to replace a serial cable.

FSCK -y
It always seem like such an obscene command, but it is quite useful.

Music uploads
I am going to upload some music clips, mostly of courses I'm working on as well as little music clips demoing gear and ideas for songs I have.
There are many sites I could upload this to. One of the most popular sites to upload to is Soundcloud.
I have an account at David Roeseners Sound Cloud
I also noticed tonight that Tumblr blogs easily allow music integration, so here is my tumblr blog.

MLC Leaf width and plans
http://www.aapm.org/meetings/amos2/pdf/59-14909-99229-745.pdf
Quick summary of findings
Surprisingly, we noticed no difference in TV coverage and sparing of OARs. Furthermore, the isodose distributions and DVHs for the RPC and TG-119 phantoms show no major dosimetric gains for the smaller MLC widths, the cord for the RPC phantom received lower doses with the 1cm MLC system (our benchmark reference), for the same TV coverage across the systems. For the clinical cases, all systems gave comparable TV coverage and sparing of the OARs, with the Primus MLC system again, to provide slightly better conformity (lower CI). This better dose conformity is the reason that the dose fall-off within the "Ring" structure is higher, for the Primus system.
Conclusions:
This study is the first that comprehensively compares the majority of today’s MLC systems and has shown no significant indication that smaller MLC widths can lead to optimal plans, when multi-field IMRT techniques are used for planning.

Another physicist/musician blog.
Looking forward to hearing some of his music, his early composition work looks promising. I think he has inspired me to start working on recording some compositions of my own. I do this off and on but haven't released anything for public consumption yet.

Neoclassical Guitar
Back in the 80's i had one of Dave Celentanos books, for neoclassical guitar. He has a great youtube video where he plays Pachabel Canon.
