July 8, 2019 — At this year’s American Association of Physicists in Medicine (AAPM) show, July 14-18 in San Antonio, Texas, PTW will exhibit its full range of dosimetry solutions for magnetic resonance-guided radiotherapy (MRgRT), beam data commissioning and stereotactic quality assurance (QA).

PTW will exhibit and demonstrate its latest technology and most recent product developments including:

  • Beamscan MR 3-D water phantom – The first 3-D water phantom for MR-guided radiotherapy, according to the company, available in two models for Elekta Unity and ViewRay MRIdian. Beamscan MR 3-D is pending U.S. Food and Drug Administration (FDA) 510(k) clearance and is not available for sale in the U.S.;
  • Beamscan 3-D water phantom – Fast to set up and easy to use for all acceptance testing and commissioning needs, now available for the Halcyon system;
  • Octavius 4-D modular patient and machine QA systems – For the latest radiotherapy techniques, including Halcyon, stereotactic radiosurgery (SRS) and MRgRT. Also introducing Octavius Detector 1600 SRS for 3-D dose verification of complex SRS/SBRT (stereotactic body radiation therapy) treatment plans;
  • Ruby phantom – A new modular stereotactic verification phantom with multiple inserts for comprehensive system QA, linear accelerator (linac) QA and patient QA:
  • StarCheck arrays – High-resolution ionization chamber arrays for comprehensive, TG-142-compliant linac QA, available in three models for standard (25 x 25 cm²), large (40 x 40 cm²) and magnetic fields;
  • microSilicon diode detector – The new silicon diode detector for small photon and all electron fields; and
  • Track-it 2.0 QA data management software – Versatile, web-based QA data management software that integrates QA data from different sources, devices and sites into a single platform.

PTW is hosting a Lunch and Learn symposium for AAPM attendees on Monday, July 15. The event will feature the following presenters:

  • Jochem Wolthaus, Ph.D., a medical physicist at the University Medical Center Utrecht, will present “The Development and Experience of the first MR-compatible 3-D Scanning Water Tank for Acceptance, Commissioning and QA measurements in an MRI-LINAC”; 
  • Dan Nicewonger, a medical physicist at the MD Anderson Cancer Center in San Antonio, will present “QA Data Flow in Modern Radiotherapy Departments”; and
  • Sharon Thompson, a medical physicist from the Maimonides Cancer Center, Brooklyn, N.Y., will present “Challenges of Beam Data Collection and Validation of Halcyon during Commissioning.”
