KV Imaging Systems for Linear Accelerators
kV (kilo voltage) imaging systems provide your image-guided radiation therapy (IGRT) with digitally reconstructed radiographs (DRRs) to better direct radiation therapy. The device looks like right and left ‘arms’ that extend from the gantry of a linear accelerator. One arm contains the x-ray tube and the other arm contains a specialized detector. These generate images of the patient before radiation therapy as well as during the treatment process and allow for much higher quality images than the EPID device. kV imaging systems are found on most linear accelerators(LINACs) available in the U.S. today, and they allow for image-guided radiation therapy (IGRT) as well as cone beam computed tomography (CBCT). With the right hardware and software upgrades, a KV-Imaging Device is essential in performing VMAT (Volumetric Arc Therapy).
Radiology Oncology Systems offers several pre-tested, pre-owned kV imaging devices for the following systems:
WE CARRY A STOCK OF TESTED, PRE-OWNED KV IMAGING SYSTEMS FOR THE FOLLOWING SYSTEMS:
- Varian’s KV Imaging Device is referred to as an OBI, short for “On Board Imager.” Earlier Varian Systems have OBI upgrades, and newer systems come with OBI Systems out of the factory. These devices are available only on Varian dual energy systems. They are not available on 600C, 600 C/D, 6EX or unique models.
- Elekta’s KV Imaging Device is known as the XVI (X-ray volume imaging) system. It too is “bolted on” to the linear accelerator.
- Brainlab ExacTrac System is a stand-alone, independent KV Imaging System that uses two detectors placed on the floor near and two x-ray tubes in the ceiling, but does not physically reside on the linear accelerator
Radiology Oncology Systems also carries an assortment of pre-owned KV Imaging systems that may be appropriate for practices and medical facilities with budget constraints or those who treat relatively few patients. However, because of software licensing requirements, the bolt-on models, such as the Varian OBI detector and the Elekta XVI, are most commonly installed by the OEM. If you aren’t sure which kV imaging device to purchase for your practice or medical facility, contact ROS for further insight on which device works best for you.
