Target Mounting Assembly for Isocenter Verification Systems

Product Specifications

Technical details and manufacturing context for Target Mounting Assembly

Definition

The Target Mounting Assembly is a component of the Isocenter Verification System, designed to provide precise and repeatable attachment and spatial orientation of calibration or verification targets. It holds the target in a fixed, known position relative to the system's reference frame, enabling accurate measurement and verification of the radiation isocenter in medical linear accelerators or similar radiotherapy equipment. The assembly typically consists of a rigid frame or bracket with adjustable or fixed mounting points, interfacing with the verification system's structure to provide a stable platform for the target (e.g., a phantom, marker, or detector). Its design minimizes deflection and vibration, maintaining target position integrity during system operation and measurement procedures. The assembly is available in aluminum alloy (6061-T6) or stainless steel, with a black anodized surface treatment (Type II, class 2) for corrosion resistance. It features mounting holes for M6–M8 bolts, adjustment ranges of ±5 mm in X/Y and ±3° in tilt/pan, positioning accuracy of ±0.05 mm, and load capacity of 5–10 kg. Operating temperature range is -40 to 85 °C, ingress protection IP54–IP65, and weight 0.8–1.2 kg. The assembly is designed for compatibility with IEC 60601-1 for medical device safety. All values are reference ranges; verify model-specific specifications with the legal manufacturer or supplier.

Working Principle

The assembly uses a rigid frame or bracket with mounting points that interface with the verification system's structure. It provides a stable platform for the target, with adjustable or fixed positioning to achieve the required orientation. The design minimizes deflection and vibration, ensuring the target remains in a fixed, known position during measurement procedures. Adjustment mechanisms allow for fine-tuning in X/Y and angular directions, while the mounting holes accommodate standard bolts for secure attachment.
