Clinical experience: Using Delta4 Phantom+ and HexaMotion for confidence in advanced QA

Clinical experience. Learn how Hospital Gómez Ulla uses Delta4 Phantom+ and Delta4 HexaMotion to support an efficient radiotherapy patient QA workflow and motion management in clinical practice.

Delivering radiotherapy requires confidence at every stage of the treatment workflow. Medical physics teams rely on independent patient quality assurance (QA) and robust motion management to safely deliver complex treatments.

In this recorded presentation, Francisco Javier San Miguel Avedillo, Head of Radiation Protection and Medical Physics, introduces Delta4 Phantom+ and  Delta4 HexaMotion and demonstrates their role in patient QA and motion management through clinical cases.

Motion Management with Delta4 HexaMotion

As treatment precision continues to improve, tumor motion becomes an increasingly important consideration during radiotherapy. Francisco Javier San Miguel Avedillo explains how his department uses Delta4 HexaMotion to simulate realistic, tumor motion during the QA process. This enables the physics team to evaluate moving targets and verify motion-managed treatment plans.

Frequently Asked Questions

How does Delta4 Phantom+ improve independent patient QA efficiency? Delta4 Phantom+ measures the 3D dose distribution in the isocenter region using two orthogonal detector planes. Combined with wireless operation and instant analysis and result, it provides fast, independent verification of complex treatment plans, supporting an efficient QA workflow.

How do you handle motion management QA using Delta4 solutions? The HexaMotion motion platform is used together with the Delta4 Phantom+ to provide a full analysis of the dosimetric effect of tumor respiratory motion. The true delivery of the prescription dose can be studied in detail for each patient and critical structure, allowing the clinician to easily identify which patients or which groups of patients require motion management.

This helps answer questions such as:

• Am I hitting the target?
• What is the benefit of tumor tracking or gating?
