mrtm1_tstar | R Documentation |
Function to identify where t* is for MRTM1. Remember that this is unnecessary if the kinetics in the target tissue can be described by a one tissue compartment model (like SRTM).

)
t_tac |
Numeric vector of times for each frame in minutes. We use the time halfway through the frame as well as a zero. If a time zero frame is not included, it will be added. |
reftac |
Numeric vector of radioactivity concentrations in the reference tissue for each frame. |
lowroi |
Numeric vector of radioactivity concentrations in a target tissue for each frame. This should be from a ROI with low binding. |
medroi |
Numeric vector of radioactivity concentrations in a target tissue for each frame. This should be from a ROI with medium binding. |
highroi |
Numeric vector of radioactivity concentrations in a target tissue for each frame. This should be from a ROI with high binding. |
filename |
The name of the output image: filename_mrtm1.jpeg |
frameStartEnd |
Optional: This allows one to specify the beginning and final frame to use for modelling, e.g. c(1,20). This is to assess time stability. |
gridbreaks |
Optional. The size of the grid in the plots. Default: 2. |
Saves a jpeg of the plots as filename_mrtm1.jpeg
