Roles & Permissions

Overview

Tasks Manager supports various clinical trial roles with specific permissions that align with typical imaging study workflows. Understanding how clinical trial personas map to Flywheel permissions helps you configure appropriate access controls for your study team.

This guide maps common clinical trial roles to the permissions they need to perform their responsibilities in Tasks Manager.

Clinical Trial Personas

Reader

Clinical Trial Responsibilities:

• Review medical images according to protocol
• Create annotations and measurements
• Complete assessment forms
• Submit completed readings with e-signatures

Required Flywheel Permissions:

• At least read-only role access to assigned projects
• Ability to create, view, modify, delete annotations

Typical Access Pattern:

• Can only view and complete tasks assigned to them or their staffing pool
• Cannot see other Readers' tasks or annotations (blinded)
• Cannot create or assign tasks
• Cannot modify protocols or project settings

Adjudicator

In a Double Read with Adjudication workflow, the adjudicator resolves discrepancies between the two independent reads of the same dataset.

Clinical Trial Responsibilities:

• Review both readers' completed reads for the same dataset
• Select one reader's read, modify a read, or perform an independent read
• Complete the adjudication with an e-signature where required

Required Flywheel Permissions:

• The same permissions as a Reader — an adjudicator does not need the Manage Tasks permission
• Assigned to Adjudicator Tasks individually or through a Staffing Pool
• A separate Staffing Pool is required for the Adjudicator task assignment

Typical Access Pattern:

• Can only view and complete Adjudicator Tasks assigned to them or their staffing pool
• Cannot see an Adjudicator Task while it is Blocked (that is, before both reads are complete)
• Cannot adjudicate a dataset they read (reader/adjudicator exclusivity)
• Has the same permissions as the Reader persona in the tables below

Study Administrator

Clinical Trial Responsibilities:

• Create and assign reading tasks to Readers or staffing pools
• Manage staffing pools and reader assignments
• Configure protocols and project settings
• Monitor task progress and completion
• Review completed tasks and annotations from all Readers (unblinded access)
• Export task data and generate reports
• Manage user permissions within projects

Required Flywheel Permissions:

Site:

• Site Admin Role - for Staffing pool management

Group:

• Read/Write Role - for Protocol creation and editing permissions

Project:

• read-write access to projects
• Manage Tasks permission
• Manage Task Exports permission
• Project settings and permissions management

Typical Access Pattern:

• Can create tasks for any session/acquisition in their projects
• Can assign tasks to Readers or staffing pools
• Can view all tasks in their projects (including completed tasks from all Readers)
• Can view all annotations and form responses from all Readers
• Can create and modify protocols
• Can configure project settings and manage user permissions
• Can export task data reports
• Cannot modify completed tasks or Readers' annotations directly

Detailed Permission Mapping by Persona

The following tables detail the specific Flywheel permissions recommended for each clinical trial persona, showing the Reader and Study Administrator personas. These tables map to the standard Flywheel permission system and include Tasks Manager-specific permissions for tasks and protocols.
