 North Staffordshire’s new state of the art cancer centre is adding more new technology – in the form of Quality Assurance (QA) systems. The recently opened cancer treatment centre in north Stoke on Trent has purchased the Sun Nuclear ArcCHECKTM 4D detector array to perform QA of its treatment plans. With new Varian Rapid Arc® linear accelerators delivering IMAT rotational beams the Stoke Physics team needed a device that could measure the rotational beam in real time and with pin point accuracy.
The ArcCHECK is a cylindrical isotropic array utilising a helical diode configuration (HeliGridTM). 1386 hardened Sun Nuclear diode detectors are configured in a 21cm long, 21cm diameter cylinder within a QA phantom. The unique ArcCHECK detector geometry addresses a critical need for better and more uniform Beams Eye View (BEV) measurement of new rotational modalities. Using an enhanced version of the well proven MapCHECK software, ArcCHECK℗ imports TPS, measures delivered dose and performs a dose comparison. DVH (dose volume histogram), DICOM-RT structure imports and profile extractions are all features of the device.
