Revision
Fixed a performance problem. It turned out not to be a leak, just an inefficiency in the way that radio waves emitted by nuclei were being done.
0.01.12
Added selection of materials to the Simplified NMR panel, along with their gyromagnetic frequencies in the model, but am unsure just how they should behave.
0.01.11
Changed the way field strength is represented in the play area in an attempt to better convey how the gradient lies across the sample area.
0.01.11
Changed the way noise is injected so that the ratio of spin up to spin down dipoles is as close to the desired ratio as possible at all times.
0.01.11
Thermal noise is now inversely proportional to field magnitude
0.01.10
Fixed 2X problem with field readout
0.01.10
Changed the graphics for the magnets to something I think may work better.
0.01.10
Added a detector. I expect we can do much better than this, however.
0.01.10
Added vertical gradient magnet.
0.01.09
Added thermal noise that flips a random atom at random times.
0.01.09
Protons in tumor respond more to photons. I did this by making these protons (and only these) NOT absorb the photons that hit them
0.01.09
Change numbers in readout for gradient magnet to range from 0 to 2, and have the current representation arrows reflect those numbers. The field produced by the gradient magnet should remain the magnitude it is right now, however.
0.01.09
Changed gradient on magnet so 0 point is at the center. Field is negative to the left of center, and positive to the right.
0.01.08
Fixed performance problem by doing all graphics in screen coordinates and avoiding Piccolo transformations.
0.01.06
Improved probability gradient so that vertical distribution of photons emitted by atoms is more constant
0.01.04
Photons emitted by atoms now make it past the edge of the play area before they're removed
0.01.04
Increase target size of atom
0.01.03
Add atoms in the ears
0.01.03
Make tumor more dense with hydrogen
0.01.03
Make the "Add Tumor" button toggle to "Remove Tumor"
0.01.03
Main magnet should have a minimum current that keeps the arrow in the control panel visible (but small)
0.01.03
Fix sizing of play area so controls are completely visible
0.01.03
