Brachyvision 6.0 is designed to allow the dose distribution of an implant or applicator to be individually shaped for each patient. Brachy Vision is a general purpose brachytherapy planning system used for prospective and confirmation dose calculations for patients undergoing a course of brachytherapy, using either temporary or permanent implants of various radioisotopes. Brachy Vison 6.0 may be used for any brachytherapy planning activity, but has been specifically optimized for use with remote afterloaders (especially the VariSource unit from Varian), and for use with 3D images such as may be obtained from CT or MRI, or Ultrasound images.

Brachy Vision is a computer based product used for calculating and displaying prospective or verification treatment plans for particular patients undergoing a course of Brachytherapy. The system consists of a computer with graphics display, film scanner input, and plotter output. Patient data may be entered from network connection, via the film scanner, via the optional back lit digitizer, or via the keyboard. Source placement information may be added to the patient data and isodose distributions, which would result from those source placements, may be displayed, analyzed and plotted. For use with remote afterloader devices, source dwell times may be optimized to user selected criteria.

Somavision is an advanced treatment planning preparation workstation for the physician and include high quality 3-D image capabilities. As part of the Varis Vision System, Somavision integrates treatment palnning in the overall therapy process, while taking advantage of the Varian Vision database.

Somavision is an advanced treatment planning preparation workstation with 3D image capabilities.

CadPlan 6.0 is used to plan radiation therapy treatments employing linear accelerators and other similar teletherapy devices with x-ray energies from 1-50 MV, as well as Cobalt-60, and electron energies from 1 to 50 MeV, and to plan brachytherapy treatments. CadPlan will plan the 3D radiotherapy treatment approaches to combined modality plans, asymmetric and non-coplanar field, total body irradiation, multileaf collimators, motorized and dynamic wedges, customized blocking, compensating filters, and bolus. CadPlan 6.0 includes export capabilities to verify beam and patient date, dose-planning results, and provide on-line information to block-cutting devices.

CadPlan 6.0 is a comprehensive 3D Treatment Modeling Workstation for external beam and brachytherapy planning.

The Varian Millennium 120 Multileaf Collimator (MLC) is provided to assist the radiation oncologist in the delivery of radiation to defined target volumes while sparing surrounding normal tissue and critical organs from excess radiation. In a static mode, the MLC performs the same function as the customized shadow blocks. In a dynamic mode, a series of MLC leaf positions can be indexed to either Clinac® dose fraction or gantry angle to create a changing beam shape while the radiation beam is on to create a three dimensional dose distribution.

The Varian Millennium Multileaf Collimator (MLC) is an x-ray collimator designed to be mounted on a C or EX Series Varian Clinac® radiation therapy linear accelerator beneath the standard field defining the collimator jaw.

The Varian VariSource™ Remote High Dose Rate Afterloader [system, including applicators and accessories] is a device intended to be used by properly trained and licensed medical personnel to provide radiation brachytherapy. The VariSource Wright Vaginal Cuff applicator which is the subject of this 510(k) is a component of the VariSource system.

Applicators for the Varian VariSource Remote High Dose Rate Afterloader are a part of a remote controlled radionuclide applicator system, including an electromechanical device to enable an operator to apply, by remote control, a radionuclide source of high activity at various internal or surface body locations for radiation brachytherapy. The shape and materials of the applicator determine where it will be utilized for treatment.

The Varian VariSource Remote High Dose Rate Afterloader system, including the applicators included in this notification, is a device intended to be used by properly trained and licensed medical personnel to provide radiation brachytherapy with a high specific activity radioisotope source to reduce the exposure times required to achieve a prescribed dose.

The applicators for the Varian VariSource Remote High Dose Rate Afterloader are part of a remote controlled radionuclide applicator system, including an electromechanical device to enable an operator to apply, by remote control, a radionuclide source of high activity to be placed at various internal or surface body locations for radiation brachytherapy. The shape and materials of the applicator determine where it will be located for treatment.

CADPLAN BT is designed to allow the dose distribution of an applicator to be individually shaped for each patient.

CADPLAN BT is a Windows NT software application that is designed to work together with the VariSource High Dose Rate Remote Afterloader. It allows for applicator placement for up to 20 channels, and allows dose distribution of an applicator to be individually shaped for each patient. It also allows for calculation of the dwell time of the catheter.

To assist the therapist in verification of the treatment field and shielding blocks in relation to anatomical landmarks in radiotherapy treatment.

VARiS PortalVision™ is an on-line electronic portal imaging system which allows for verification of the treatment field and shielding blocks in relation to anatomical landmarks in radiotherapy treatment. The imaging mechanism of VARiS PortalVision™ is an ionization chamber. VARiS PortalVision™ is fully integrated into Varian's VARiS environment. It is a subsystem of the VARiS Images application. The VARiS PortalVision™ software supports image acquisition, image processing, and image evaluation by means of quantitative comparison tools. As a subsystem of VARiS Images, VARiS Portal Vision™ runs on the VARiS Images workstation. The VARiS Images workstation is based on an Intel Pentium processor based PC running Microsoft Windows NT or the Win 95 operating system.
