IMT showcases simple and fast phantoms for stereotactic radiosurgery

IMT, a US company that specializes in quality-assurance (QA) solutions, will be highlighting two phantoms that provide simple and fast QA for stereotactic radiosurgery (SRS). The MAX-EI and MAX-EA offer end-to-end SRS QA for less than $10,000 ($7500 for 2019 early adopters), and includes embedded Winston-Lutz central and offset targets for fast, easy and repeatable Winston-Lutz verification.

“We have been using the MAX-EI to gather SRS validation data because it provides a unique, pseudo-anthropomorphic geometry which allows us to quickly check our IGRT and SGRT end-to-end accuracy, while also providing precise spatial and dosimetric validation data in one simple setup,” commented Michael Tallhamer, chief of radiation physics at Centura Health, who has performed a clinical evaluation study of the device.

IMT’s products are manufactured with precise tolerances, under 0.15 mm, virtually eliminating the phantom itself from any variation in measurement. This high level of precision provides IMT product users with excellent repeatability over time as well as repeatability across multiple machines and sites. The MAX-EI and MAX-EA also benefit from IMT’s new SRS Quality Audit & Peer Review Service.

Phantom exploits spherical design to deliver precision measurement

The Magphan series of phantoms from Image Owl makes it possible to precisely evaluate the performance of magnetic-resonance imaging (MRI) systems and correct for any distortion in the images. Magphan models exploit test objects developed from more than a decade of scientific investigation and field experience, with different designs available for specific applications.

The Magphan RT, for example, offers an integrated phantom and analysis system for MRI quality assurance in radiotherapy, using arrays of precisely located spheres to provide an accurate and detailed 3D map of image distortion. The S162 model is optimized for applications where MRI scanners are used for quantitative imaging, particularly in cases where geometric distortion can have a critical impact, while the EMR051 and the smaller EMR121 phantoms are suitable for neuroimaging and for measuring distortion in radiation therapy planning and guidance scanners. An automated analysis service tracks key parameters, and saves results in a cloud-based database for longitudinal studies, process control, and inter-machine comparisons.
