The linear accelerator Elekta Versa HD TM used in this study produces 6 MV photon beam with no wedge. This is because the Agility MLC can move faster than the Varian MLC, so dose modulation in the Versa HD does not require a decrease in the dose rate during treatment delivery. Varian TrueBEAM : 2 . 1 : 3 . Therapy General ePoster Viewing. Varian, Elekta, Siemens, and Accurays TomoTherapy and CyberKnife; Data from high dose rate and flattening filter free capable machines such as the Varian TrueBeam and Elekta Versa HD are also seamlessly acquired We have the QA BeamChecker Plus at three sites; It is the best device I have used in 25 years as a medical physicist. rnein, Varian TrueBeam. Radyoterapi, external (dardan) ve internal (ieriden) olmak zere iki farkl ekilde yaplr. found that the positional variations of the off-isocenter targets were less than 1 mm on a Novalis Tx Linac [19] . Results: Three Varian True Beam, two Elekta Infinity and four Versa HD linacs at five institutions were tested using identical methodology. Learn more. however, the Elekta design provides more clearance than the Varian approach. Varian calls it High Intensity Mode. I work at the hospital that has both Varian and Elekta solutions I recommend you to go for Varian option. Varian calls it High Intensity Mode. Innovative and versatile treatment. For example, the isocenter diameter of a TrueBeam platform (Varian Medical Systems, Palo Alto, USA) was 0.49 mm according to a previous study . high dose rate, flat, SRS beams max field only 10x10 cm2, filter can be (and is) thinner than cFF But e.g. The same figures for Versa HD units are 0.684, 0.678 (6 MV) and 0.734, 0.721 (10 MV).

External radyoterapide Elekta Versa HD veya dier Linac trleri kullanlr. This absolute verification was performed in the QA target, while the 3D dose distribution from the gel translates this accuracy to the other targets. Compared to Varians other systems, TrueBeam delivers treatments up to 50 percent faster and with a dose delivery rate of up to 2,400 monitor units per minute, double the maximum output of earlier systems. It delivers high-energy x-rays or electrons to the region of the patient's tumor. Elekta FFF beam qualities, different from the Varian generated beams, tend to express similar behaviour as the FF beam of the corresponding nominal energy. This is the only time that we recommend taking the battery all the way down to zero %. We are having a lot of issues with Versa HD machines, especially with the KV imaging devices. Filtration: 2 mm stainless steel (TrueBEAM vs Gold Beam) The FFF beam has a different apparent energy than the conventional 10MV beam depth in water (mm) P-ion for HIM (FFF) beam : 1.0120ion for HIM (FFF) beam : 1.0120 P-ion for conv. 12 Clinical Applications 2013 Purpose: To investigate the clinical application of FFF beams at maximum dose rate for SBRT. A pre-owned linear accelerator such as a Basic Varian 600CD/6EX can be purchased for around $175,000 to $300,000. It was engineered from the ground up to deliver more powerful cancer treatments with pinpoint accuracy and precision. Our D10 at FVSD was within 0.2% (~ 67.8% PDD) Existing literature largely relates to the Varian True Beam accelerators that implement FFF beams in an unmatched mode, whereby FFF beams are produced TrueBeam radiotherapy system is a medical linear accelerator developed by Varian Medical Systems. 55 Organic Competition.

Linear Accelerator Helical Brand Names Accuray TomoTherapy Varian Halcyon Modalities IMRT (helical) 3D Conformal Particulars Rotating linear accelerator Deliver precise dosage quickly and give patients their time backthe TrueBeam radiotherapy system is built with human needs in mind. Varian and Stockholm-based Elekta are expected to introduce new platforms this year and Accuray, based in Sunnyvale, Calif., recently launched a new version of its robotic system. Although it has been widely adopted in many clinics for patient treatment, limited information is available related to commissioning of this type of machine. The same figures for Versa HD units are 0.684, 0.678 (6 MV) and 0.734 0.721 (10 MV). For example, the newer Elekta machine (Versa HD), with lower MLC transmission factor (<1% for the 6- and 10-MV FFF), is expected to show an important reduction of the PD. TPR 20,10 for 6 and 10 MV FF and FFF TrueBeam beams are 0.665, 0.629 (6 MV) and 0.738, 0.703 (10 MV). Truebeam versus Versa HD If your hospital was willing to buy your department the latest machine from either Elekta or Varian which one would you get and why? However, the homogeneous dose delivery of small-field irradiation techniques shows disagreement with that of treatment planning system. Traffic to Competitors .

In preparation for departmental upgrades, Willis-Knighton faced a choice of vendors to enhance radiation oncology operations. The Varian approach shields the area surrounding the shaped portion of the field to a leakage level that is much lower than the required 0.5% of the open field value. An RTsafe PseudoPatient 3D gel phantom was used to demonstrate SRS treatment accuracy and delivery confidence with a single isocenter VMAT technique to treat multiple brain metastasis. PO-GePV-T-1 : A Nomogram to Estimate Required Ci-S in Prostate HDR Brachytherapy. Available with 6MV & 10MV energy on TrueBeam Linacs. Newsletters. Varian linacs exhibited substantially less deviation due to head sag than Elekta linacs (0.4 mm vs. 1.2 mm on average). Therapy General ePoster Viewing. The 2.3-million Varian TrueBeam machine, known as the Brunel, treats up to 40 patients a day across a variety of tumour types, including breast, lung, head and neck, prostate, gastrointestinal and gynaecological cancers. The removal of the flattening This paper could potentially streamline the commissioning of a Versa HD, thus saving time and money. What marketing strategies does Varian use? According to the American Association of Physicists in Medicine (AAPM)s Task Group (TG) reports (Klein et al. Traffic to Competitors . Officials at the cancer center decided to acquire a pair of advanced Elekta Versa HD systems and decommission their two Varian 21EX systems, each Images are automatically sorted and analyzed using a built-in Cerberus script to significantly reduce QA time and lessen the burden of performing routine QA procedures. (18 plans created for the Varian True beam machine). 2 . RIT provides Varian users with a standardized patient file, pre-loaded with treatment plans, covering every TG-142 test that the RIT Family of Products can analyze. As evidence continues to grow for new SRS and SBRT indications, ensure you have the right platform to empower the treatments of tomorrow. Elekta FFF beam qualities, different from the Varian generated beams, tend to express similar behaviour as the FF beam of the corresponding nominal energy. Deliver IMRT, SBRT and VMAT with ease and confidence. SBRT can be delivered with a variety of modern treatment systems, including linear accelerators such as Truebeam, Halcyon, and Edge of Varian Medical Systems, Versa HD and Infinity HD of Elekta, Cyberknife and Tomotherapy of Accuray. Reduce non-therapeutic body dose. In Varian the source-EPID distance is variable and the panel can go up to the isocenter (which is useful for linac QA), while in Elekta the distance is fixed. I think Varian recently introduced tools to automate the linac daily QA, while Elekta doesnt have anything similar. At our institution, two Elekta VersaHD LINACs (Elekta Instruments AB, Stockholm, Sweden) were matched with each other and commissioned utilizing one mutual beam dataset for treatment planning and delivery. Intensity-modulated radiotherapy and volumetric modulated arc therapy are modern radiation therapy technologies that can create the desired dose distribution by multileaf collimator movement and dose-rate control. Deep integration with Elekta Versa HD in combination with Hexapod and Varian Edge or TrueBeam with Perfect Pitch enable automated beam holdrepositioning and restarting treatmentfrom the linac console. Siemens . These treatments can be designed in such a way that they destroy the cancer cells while sparing the surrounding normal tissue.
