Clinicians at Evangelische Kliniken Gelsenkirchen in Germany used Elekta’s Versa HD system for the first time on 28 October 2013 to treat a 72-year-old female patient with advanced (metastatic) cancer.
According to Evangelische Kliniken, the Versa HD system boosted radiation therapy speed and accuracy.
The clinic found that the Versa HD treatments were faster and more accurate and provided more protection to surrounding healthy organs when compared with treatment on the clinic’s existing linear accelerator with which the patient received her first few fractions.
Evangelische Kliniken chief physician Dr Razvan Galalae said, "This was a seven-field, 56-segment IMRT treatment, and what we found was that – in comparison with our other system – Elekta’s Versa HD afforded better dose conformance to the target and enhanced avoidance of critical structures, such as the small bowel, kidneys, rectum and bladder."
While Dr Galalae attributes these initial observations to Agility, the Elekta system’s advanced, high-speed beam-shaping multileaf collimator (MLC), Agility is just one major feature of Versa HD.
Clinicians at Evangelische Kliniken are anticipating even greater success in beam delivery speed with the system’s High Dose Rate mode.
In the three weeks following the first case, the clinic put 15 additional patients on the Versa HD schedule, supporting the impact that the system has had on radiotherapy speed and accuracy. Ultimately, the clinic aims to reach around 50 patients per day.
"Our expectations have been met with our Versa HD system, which is among the first installed in Germany," Dr Galalae added.
