IBA Releases Dolphin Online Ready Patient QA and Monitoring System

System enables more efficient pre-treatment patient QA, with future online treatment monitoring for safer delivery of each treatment fraction enabled after linac interoperability confirmation

April 27, 2016 — IBA (Ion Beam Applications S.A.) announced the release of Dolphin Online Ready Patient QA and Monitoring. Dolphin enhances workflows in pre-treatment QA (quality assurance), while being mindful of future online treatment monitoring.

To achieve added efficiency, Dolphin offers a “plug-and-play” design that enables significantly faster pre-treatment QA. Dolphin only requires two minutes to set up and wirelessly transmits the measured detector response to the Dolphin workstation. Additionally, the new automatic verification software QuickCheck saves valuable time by providing instant analysis of the Dolphin measurements and giving an “OK” message for the tests successfully passed.

This design ensures that Dolphin will enable future online treatment monitoring by measuring the actual delivery during patient treatment and by automatic QuickCheck verification immediately after each fraction, seamlessly integrating into the therapist’s workflow.

“The Dolphin will offer the possibility for online verification of complex dose delivery techniques such as IMRT [intensity modulated radiation therapy] or VMAT [volumetric modulated arc therapy] with the patient already in treatment position. Used for multiple treatment fractions the system even offers inherently a new possibility for cumulative delivered dose tracking,” said Dr. Hansjoerg Wertz, Dept. of Radiation Oncology, University Medical Centre Mannheim, University of Heidelberg, Mannheim, Germany in the name of the whole “Dolphin team” at UMM. “The novel online QA system contributes to reduce extra pre-treatment QA time to a minimum while at the same time increasing patient safety and preventing severe accidents due to the immediate detection of dose delivery errors. Based on our intensive initial experiences, we are planning to implement Dolphin into our clinical routine workflow for our patient verification during treatment as soon as possible. This gives us the ultimate confidence in treating our patients safely.”

Dolphin offers not only a simple consistency check but is coupled with the advanced analysis of each measured dose, and in turn, offers a complete patient QA solution. The clinical relevance of the dose discrepancies is comprehensively determined with DVH and in 3-D patient anatomy using sophisticated TPS-Class verification software. Following this verification process, the clinical team can determine whether re-planning or plan adaptation is needed or machine-specific parameters can be verified.

Dolphin is also designed for future applications, such as Machine QA and Adaptive-QA using cone beam computed tomography (CBCT) and dose of the day. The versatility of Dolphin makes it the universal detector for integrating future real time measurements into IBA’s myQA global QA platform for several key dosimetry applications, from Patient QA to Machine QA and more.
