Acquisition and Data Requirements
Image Data |
A dynamic PET data set with an appropriate tracer. |
TAC 1 |
TAC from a region with irreversible binding (such as caudate for FDOPA). |
TAC 2 |
TAC from a region without irreversible binding (such as occipital or cerebellum for FDOPA). |
Model Preprocessing
Two regional TACs (TAC1 and TAC2) are needed for Model Preprocessing.
t* |
The linear regression estimation should be restricted to a range after an equilibration time. t* marks the beginning of the range used in the multi-linear regression analysis. It can be fitted based on the Max. Err. criterion. Note that the t* is in acquisition time. |
Max. Err. |
Maximum relative error allowed between the linear regression and the Patlak-transformed measurements in the segment starting from t*. |
Threshold |
Discrimination threshold for background masking. |
K |
Slope of the linear regression. K=(k2*k3)/(k2+k3). |
Intercept |
Intercept of the linear regression. |
Start |
Time in the plot which corresponds to t*. |
Map Parameters
K |
Slope of the linear regression. K=(k2*k3)/(k2+k3). |
Intercept |
Intercept of the linear regression. |
