Technical details and manufacturing context for Treatment Couch

Definition
The treatment couch is a critical component of a medical linear accelerator system designed to precisely position and support patients during radiation therapy. It provides a stable, adjustable platform that allows for accurate alignment of the patient's treatment area with the radiation beam, ensuring targeted delivery while minimizing exposure to healthy tissues. The couch typically features motorized movements in multiple axes (vertical, longitudinal, lateral, and rotational) with sub-millimeter precision, integrated imaging compatibility, and patient immobilization accessories.
Working Principle
The treatment couch operates through a combination of mechanical, electrical, and control systems. Motorized actuators (typically servo or stepper motors) drive precision lead screws or linear guides to move the couch top in multiple directions. A computerized control system interfaces with the linear accelerator's treatment planning software, allowing for automated positioning based on pre-planned coordinates. Load cells and position encoders provide feedback for precise movement control and patient weight monitoring. The couch structure is designed to minimize radiation attenuation while maintaining rigidity and stability.

Engineering Reasoning
Load capacity: 0-250 kg, Positioning accuracy: ±0.5 mm, Vertical travel: 0-200 cm, Longitudinal travel: 0-200 cm, Lateral travel: 0-50 cm, Rotation: ±180°
Structural deformation at >300 kg static load, Positioning error >2.0 mm RMS, Motor torque >15 Nm causing gearbox shear, Encoder resolution loss at >0.1 mm backlash
Design Rationale: Yield strength exceedance of 6061-T6 aluminum alloy frame (275 MPa), Worm gear tooth shear stress >400 MPa, Ball screw elastic deformation under >5000 N axial load, Linear bearing raceway Brinell damage at >600 HB
Risk Mitigation (FMEA)
Trigger Ball screw thermal expansion differential of 12 μm/°C between steel screw and aluminum mounting
Mode: Positioning drift accumulation exceeding 1.5 mm over 30-minute treatment
Strategy: Invar alloy coupling with 1.2×10⁻⁶/°C CTE and active thermal compensation using PT100 sensors
Trigger Permanent magnet synchronous motor demagnetization at >150°C winding temperature
Mode: Torque loss from 12 Nm to 4 Nm causing couch slippage during patient rotation
Strategy: NdFeB magnets with Hcj >2000 kA/m and embedded K-type thermocouples with 95°C cutoff
