Optical System Diagram
Molecular Imaging System Upgrade: Software System Capabilities • Consist of three separate programs • Kodak Molecular Imaging Software • Optigrid Motor Control GUI • MATLAB – Scripts will be developed as necessary for calibration and depth resolved discrimination • Optigrid Calibration – A system specific calibration process will be developed – Process will rely on manual coordination of three separate programs • Implement necessary algorithms to achieve depth discrimination, as described by Tromberg et al. in US Publication 2006/0184043
Optigrid Calibration Camera Parameters Gain Offset Grid Optimization Determine Linearity Merit Function Phase vs. Voltage Full System Verification Camera Software Frequency Analysis (MATLAB, EXCEL) Optigrid Required
Depth Discrimination • Fourier transform – filtering – inverse Fourier transform • Involves using calibration reference to determine optical properties
Deliverables for Detailed Design Review • Outlined step by step process for Optigrid calibration – Including prefabricated scripts from Qioptiq – Needs to be system specific – Status: Near complete. Require input from Qioptiq • Algorithm “pseudo-code” documenting mathematical theory and envisioned procedure for implementation – Status: Preliminary document in place. To be reviewed with customer before design review
