Workflow steps:

Open-source trial-level workflow proceeds as follows:

TrialOwner User creates ClinicalTrial and TrialArm
TrialOwner specifies which patients are included in TrialArm
TrialOwner creates Timepoints (e.g. Baseline, Follow-up) through the Study Association modal for various patients
Optional: TrialOwner assign PatientIds / Timepoints to Review to Readers
Reader chooses Timepoints to Review based on Study Worklist, Timepoint Worklist, or the Reader's assigned work (new page?)
Reader loads LesionTracker with specified Timepoints and creates / updates Measurements
Measurements are saved as created/updated by Reader, Timepoint is marked as Reviewed in the TrialArm Model

In Precision Imaging Metrics approach, LesionTracker usage starts at Step 6.

Model types (from highest in hierarchy to lowest):

Users can have various privileges depending on their status: Reader, TrialOwner, Administrator, for example
Readers can only create and edit measurements
TrialOwners can create and manage trials, trial arms, and associate studies with timepoints
Administrators can create/manage/delete all data models, including other Users

Timepoints contain one or more studies
Timepoints can be part of multiple trial arms and trials
Created manually by a trial owner
- When a single Study is selected, the system suggests the inclusion of other Studies with the same StudyDate and PatientId
