Radiation oncology firm Accuray has reported positive results from the clinical study of its Radixact System to treat different types of cancer with enhanced efficiency and accuracy.
The findings were presented at the 59th Annual Meeting of the American Association of Physicists in Medicine (AAPM) held in Denver, Colorado, US, between 30 July and 3 August.

Radixact System is a smart radiation therapy that employs similar characteristics of the firm’s TomoTherapy treatment delivery.
With precision, this system enables clinicians to treat cancer cases from initial plan delivery to adaptive therapy and complex retreatments, while it also offers treatment speed and ease of use.
During the study, therapy plans created with Accuray Precision Treatment Planning System (TPS) for the Radixact were compared with those created using the VoLO Planning Solution for the TomoHDA system.
Plans developed using Accuray TPS were found to be comparatively faster with decreased beam-on time of around 50%.

By GlobalDataThe evaluation of Radixact low-dose fan beam MVCT image guidance did not show a statistically significant difference in the noise, uniformity and Hounsfield units (HU) stability over a period of three-months.
Upon assessment of beam characteristics for six months, Radixact data was found to be within the specifications determined for the TomoTherapy System, and indicated that the beam commissioning process will be straightforward.
Two studies were also performed to validate the feasibility of leveraging TomoTherapy System's helical delivery capabilities for real-time motion management.
Accuray vice-president and chief technology officer Calvin Maurer said: "The Radixact System findings reinforce what customers are experiencing in their day-to-day practice and demonstrate its value to the radiation oncology team and their patients.”
