The arrival rates of patients are defined on the Patient Arrivals objects in the model. You can right click on the Patient Arrivals icon in the library to get a list of arrival objects. The properties for this object will show how the arrivals are defined for that object and what PCI (Patient Classification Index) each arrival is.
The logic of what a patient does is defined in a Patient Track. You would need to open the Patient Track and find the activity where the decision of imaging stations is made. This will probably be found in the Patient Destination field of that activity or in the Next Activity field of another Decision Point activity that decides which Travel activity to start.
If the person who made the model put all the parameters into a global table and then referenced the correct cell of that table for field values then you might have a table of all your parameters. If not, then no there's no easy way to get a single page of all the parameters. All the parameters are defined in the fields on activities in the Track. You can click on the table button at the top of the track view to get a table view of all the fields in the activities of that track.
