Summary of Computation Speed for Major Functions in COMKAT
| COMKAT command-line functions, output solving | COMKAT GUI | COMKAT image tool | |||||||
|---|---|---|---|---|---|---|---|---|---|
| Parameter | Compiled solver | Built-in solver (ode15s) | Initialization | Model loading | Output solving and plotting | Parameter estimation | Reading and displaying images | Frame summation | Refreshing display |
| Mean | 3.2 | 124.1 | 519.6 | 615.6 | 154.2 | 595.2 | 8,146.0 | 2,044.0 | 120.7 |
| SD | 0.1 | 9.4 | 9.9 | 102.1 | 0.8 | 1.5 | 1,004.3 | 47.0 | 26.7 |
Values are time, in milliseconds. Computation is based on the 18F-FDG kinetic model of small-animal PET rat study data. For COMKAT command-line functions, the model was solved 500 times and mean and SD calculated. For GUIs, 10 repetitions were used.
