Designing safer clinical governance for radiation monitoring

02 / Overview
The Challenge
Radiation dose monitoring is a critical part of clinical imaging governance. Hospitals must ensure that scan protocols remain within safe thresholds while still producing clinically usable images.
Teamplay Dose helped institutions monitor radiation exposure — but configuring dose alerts was rigid, fragmented, and difficult to govern at scale. The workflow lacked the safeguards a high-stakes environment demands.
The product supported alerts. It did not adequately support accountability.
The workflow lacked
Standardization
No consistent threshold definitions across scanners
Approval Control
No structured review before changes went live
Governance Safeguards
Unrestricted access to alert configuration
Auditability
No traceability for threshold changes
03
03 / Problem Space
Why This Mattered
Dose alerts are not just notifications. They are institutional safety controls.
Incorrect thresholds could lead to
Missed radiation anomalies
Inconsistent clinical standards
Delayed intervention
Increased patient risk
Compliance gaps
Institutions needed a safer way to
Standardize dose rules across scanners
Reduce manual configuration errors
Review and approve threshold changes
Maintain oversight across teams and sites
The existing workflow made alert creation possible. It did not make it safe at scale.

How We Approached It
Framed as a clinical governance challenge — not a settings redesign.
01
Discovery
How institutions configured dose alerts and where the process broke down
Inconsistent thresholds, repeated manual setup, no standardization
No structured review before changes went live
02
Risk Mapping
Who creates rules vs. who validates them
What happens when thresholds change
Failure points in the existing workflow
03
Workflow Redesign
Reusable presets to reduce repetition
Controlled approvals before activation
Safer publishing logic
04
Validation
Users configure more consistently
Fewer errors and clearer ownership
Testing against clinical scenarios

07 / Design Solution
What Changed
A safer, more governable workflow for dose alert configuration.

1
Preset-based Configuration
Reusable alert presets replaced manual threshold recreation — improving consistency, speed, and standardization across scanners and sites.
2
Approval Workflow
Threshold changes moved through a structured flow: Draft → Review → Approve → Publish. Accountability was introduced before activation.
3
Role-Based Control
Different users had different authority levels — create, review, approve, publish — reducing risk from unrestricted changes.
4
Safer Publishing
Clearer states, review summaries, and approval checkpoints helped users validate what was changing before rules became active.
UI Screens / The Workflow in Detail
The Approval Journey
Four states, one governed workflow — from draft configuration to active clinical alert.
A physics expert configures a new dose alert preset — setting CTDIvol and DLP thresholds per protocol and assigning it to specific scanners. The configuration is saved as a draft, not yet active on any scanner.

Clinical Context / Dose Alerts
When Thresholds Are Crossed
Every alert is now backed by an approved preset — so when a scan exceeds threshold, the institution knows why the limit was set, who authorised it, and what action is required.
