RECITALS

Accuray is the developer and manufacturer of the CyberKnife 4^th Generation Robotic Radiosurgery System more fully described in Schedule 1 ("CyberKnife G4" or "Equipment").

Accuray's mission is to enable full-body radiosurgery using image-guided robotics. We design, develop and sell the CyberKnife G4, an FDA-cleared image-guided robotic radiosurgery system used to provide treatment planning and image-guided stereotactic radiosurgery (or precision radiotherapy) for lesions, tumors and conditions anywhere in the body where radiation treatment is indicated. Radiosurgery combines the proven capability and non-invasive nature of radiation with the precision and effectiveness of conventional surgery, thereby making it possible to non-invasively destroy solid tumors. We believe that the integration of our proprietary image-guidance system with robotic delivery capability establishes the CyberKnife G4 as the next generation of radiosurgery systems.

Institution wishes to have the use of a CyberKnife G4 in order to have the capability to provide full-body stereotactic radiosurgery/radiotherapy treatments for patients; and,

Institution and Accuray agree to enter into an agreement to share the cost of acquiring a CyberKnife G4, whereby Accuray is willing to provide the Equipment to Institution and Institution is willing to provide appropriate medical and surgical services utilizing the Equipment on the terms and conditions set forth herein.

This Agreement proposal shall expire if not signed and received by Accuray by , 2006.

Schedule 1

CyberKnife G4—Placement Equipment

List price of this configuration is $4,145,000

ROBOTIC TREATMENT DELIVERY SYSTEM

Image-Guidance Components

•: Target Locating Subsystem (TLS)—Employs two x-ray imaging systems providing a pair of orthogonal images at each treatment node. The images are digitized and compared to images synthesized from the patient's CT data. The TLS subsystem provides real-time precision information about the location of the treatment target, including compensation for small transitional movements of the patient or the target during the treatment process.
•: In-Floor Amorphous Silicon X-Ray Detectors—The imaging system uses two solid-state amorphous silicon sensor panels (40cm × 40 cm) built into the floor of the treatment room. Discrete photodiodes are arranged in a 1024 × 1024 pixel matrix. The resolution results in a pitch of 400 um. Unlike traditional imaging detectors used prior to patient treatment only, the CyberKnife state-of-the-art detectors provide direct digital output throughout treatment.
•: Target Locating System Control Console (TLSCC) and Computer—This unit controls the diagnostic X-ray sources and amorphous silicon imaging panels in acquiring images, as well as conducting image correlation to determine patient displacement during treatment.

Linear Accelerator Components

•: 600 MU/min. Linear Accelerator (Linac)—The Linac consists of an electron gun and a series of microwave cavities under vacuum. The X-band Linac provides a collimated beam of 6 MV X-rays. The compact size allows unique manipulation by the intelligent robotic system that provides hundreds of different isocentric and non-isocentric beam directions allowing high conformality and avoidance of critical structures.
•: X-Ray Head—The assembly contains the Linac, magnetron, microwave wave-guide components, the pulse transformer, water circulating connections, and a gas pressurizing connection for the wave-guide.
•: Secondary Collimators—(in millimeters: 5, 7.5, 10, 12.5, 15, 20, 25, 30, 35, 40, 50, 60, pinhole and blank) Interchangeable collimators allow for greater flexibility and conformability during the treatment planning process.
•: Modulator—This assembly contains the high voltage (HV) pulse-generating circuits that drive the Radio Frequency (RF) system located in the X-ray head.
•: Chiller—The chiller cools the Linac and consists of a re-circulating pump, a water reservoir, and a refrigeration unit with chiller and temperature regulating control (used to maintain a stable operating temperature), water temperature indicator and status lamps. This is a closed loop system that does not require external facility connections.

Robotic Manipulator

•: Unlike any other radiosurgery system in the world, Accuray's robotic system (manipulator) carries and aims the Linac providing automated positioning in six-degrees of freedom to within 0.12mm precision. It provides greater reach and flexibility than traditional gantry style linacs.

Axum® Treatment Couch & Automatic Patient Positioning System

•: Automatic patient positioning system that is fully integrated with the image-guidance system to enable accurate alignment of patients in one step.

Power Distribution Unit (PDU)

•: The Power Distribution Unit is the AC power source for the entire CyberKnife® G4 system. It uses a 208VAC, 3 phase, 150 amp input.

TREATMENT PLANNING SYSTEM

CyRIS™ MultiPlan™ Treatment Planning Computer

•: The CyRIS MultiPlan planning system, one of the newest offerings from Accuray's CyRIS family of products, combines the latest innovations in dose optimization technology and automated treatment planning tools to enable clinicians to provide radiosurgery treatments of unprecedented accuracy and effectiveness. This planning system combines forward and inverse, isocentric and non-isocentric and conformal and non-conformal planning methods, advanced image fusion capabilities for CT, MR, PET and 3D Angiography images, 2D and 3D auto segmentation and contouring tools and a powerful 3D graphical evaluation options into an easy-to-use, Windows®-based work station. With its unique real-time optimization feedback process, MultiPlan allows clinicians to make adjustments during plan optimization, an advancement that significantly accelerates the creation of treatment plans.

CyRIS™ InView™ Workstation

•: A remote image fusion and contouring station designed to streamline the pre-planning step of image preparation and tumor volume definition by enabling the user to complete this critical step within minutes from the hospital or remotely. One CyRIS InView Workstation is included.

CK Remote™ Open Architecture

•: Import DICOM RT image sets (CT, MR and PET) and ROI

CLINICAL APPLICATION MODULES

Synchrony™ Respiratory Tracking System

•: The CyberKnife System with the Synchrony Respiratory Tracking System is the only radiosurgery system in the world that identifies tumor position throughout the treatment and synchronizes treatment delivery to the motion of the tumor throughout the respiratory cycle. The Synchrony System permits patients to breathe normally during their treatment, without breath-holding or gating techniques. The System will allow physicians, for the first time, to treat their patients with much tighter margins, no longer having to add significant margins to compensate for a moving target, thus sparing more healthy tissue.

Xsight™ Spine Tracking System

•: Xsight™ Spine Tracking System from Accuray eliminates the need for surgical implantation of uncomfortable radiographic markers, or fiducials, in the delivery of radiosurgery treatments along the spinal column. Xsight relies on the bony anatomy of the spine to automatically locate and track tumors along the spinal column.

DATA MANAGEMENT SYSTEMS

Patient Archive and Restore System

•: The Patient Archive and Restore System includes a PC workstation that is networked to the CyberKnife system patient database. It allows archiving of patient records either on-line to the PC's hard drive or off-line to DVD media, as well as later restoring of patient records back into the CyberKnife system patient database for possible follow up treatment. Both of these processes occur as background processes freeing up the Treatment Delivery and Treatment Planning Systems from performing these tasks, enhancing the overall clinical workflow.
