CAPABILITIES • Commission 4D imaging and 4D radiotherapy systems • Test accuracy and reliability of real-time motion tracking through MRI imaging The CIRS MRI-LINAC Dynamic Phantom is a precision instrument for assessing MRI image quality and testing tumor localization and motion-capturing capabilities in modern radiation therapy departments utilizing stand alone MRI simulators or integrated systems for IGRT, Adaptive IMRT and VMAT. It provides known, accurate and repeatable three-dimensional target motion inside an MRI-compatible phantom. It is designed for comprehensive analysis of image acquisition,...

Proven MRI-CT-LINAC Phantom Technology T2 Axial, Coronal, and Sagittal views of moving target The phantom body, moving rod with target and extended rigid shaft connection are MRI-compatible with 1.5T magnets. Motors and motion controller electronics are located at a safe distance from the magnet to ensure MRI image quality. T2 images of MRI Distortion Grid and Central Fiducial The phantom body approximates the average human thorax in both size and shape using simplified geometries. It is comprised of a plastic shell with a cylindrical thru hole to accommodate a moving rod with simulated target....

True 3D Target Motion In an MRI-CT-LINAC Compatible Phantom The center of the target is positioned off central axis of the rod. Complex 3D motions can be achieved thru simultaneous, independently controlled linear translation and rotation. AP Within the CIRS Motion Control software, the user inputs desired range of target motion in the inferior-superior (IS), anterior-posterior (AP) and the left/right (LR) directions. Using these inputs, the software computes the rotational angles based on known distance of the target center relative to the central axis of the rod. Rotation instruction is sent...

Easy To Use Software Dynamic Phantom Motion Control Selection (Thorax or Pelvis) Instantly Start, Stop, Pause or Loop motion Graphical user interface simplifies operation of the Model 008M Real-time display of target parameters Adjust motion amplitude, cycle time and phase shift with pull down menus and slider bars Research Mode to import 3D recorded waveforms USER FRIENDLY MOTION CONTROL The Advanced Motion Parameters window contains a Research Mode that allows researchers to import 3D (x ,y, z) recorded waveforms. Once the research mode is selected, the software automatically calculates the...

Advanced Electromechanical Components ACTUATOR Housed within anodized aluminum enclosures, the actuator contains bipolar stepper motors that enable linear motion accuracy of 0.05 mm and rotational motion accuracy of 0.2°. Linear motion of the target in the (IS) direction can be isolated from rotational motion in the axial plane in both frequency and amplitude. Motions can be synchronized to one another with accuracy better than 20 msec. Motion cycle time accuracy is better than 5 msec. Optical sensors ensure precise mechanical positioning. The actuator is designed for continuous operation. If...
