These relatively low energy electron beams from the linac can also be used directly to irradiate tumours but they do not penetrate deeply into the body and therefore are not commonly used.
The Catalyst HD system, which integrates with Elekta linacs, provides gross patient positioning and postural positioning along with respiratory motion management.

These contain stereotactic radiosurgery (SRS) by using GammaKnife (GK) and CyberKnife (CK) or stereotactic radiotherapy (SRT) using CK or a linear accelerator (LINAC).1,6,7 Even though surgery presents both instancy and low rates of recurrence, the potential morbidity of surgical resection of acoustic neuromas (ANs) can be meaningful.
RT was given at the oncology department, CMH Rawalpindi using Linear Accelerator (LINAC) with two parallel antero-posterior beams covering the gross symptomatic disease with a 2 cm margin.
Background: Volumetric-modulated arc therapy (VMAT) can only be implemented on the new generation linacs such as the Varian Trilogy[sup][R] and Elekta Synergy[sup][R].
In a report to the Board Damian Heron, Director of the North Wales Cancer Network, says the five options are to do nothing, to do nothing but extend the working day of the three remaining linacs, outsourcing activity to oncology centres outside North Wales, outsourcing and extending the working day, and replacing the obsolete linac.
On the other hand, electron linear accelerators (LINACs) are increasingly becoming the most frequently used device in modern radiotherapy departments.
ExacTrac and Versa HD enable treatment of conventional as well as complex cancers that require highly accurate targeting precision, expanding the reach and richness of SRS and SBRT for facilities looking to leverage resources and deliver advanced, sophisticated therapies across several different LINACs. With its initial clinical success, the Brainlab/Elekta solution is now being sought after by hospitals around the globe, reaffirming market preference for ExacTrac across several LINAC systems.
But the word for Group 1 is, ratherfortuitously, closely related to both Group 1 itself and the motivationfor this paper: LiNaCs are the particular type of particle acceleratorwith which scientists in Darmstadt discovered six new elements, and withwhich they are currently attempting to synthesize the next element inGroup 1, tentatively named ununennium (Uue, or element 119).
It brings the value of new linacs at the trust to around PS3,200,000 and the investment has been hailed as great news for local cancer sufferers who can benefit from IMRT treatment at University Hospital in Walsgrave.
Nondedicated linear accelerators (Linacs) capable of delivering treatment with electrons have been used for intraoperative irradiation of many other tumors [14, 15].
