Particle Beam Support Member for Lateral Patient Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing particle beam treatment systems face challenges in accurately irradiating treatment sites when patients are positioned laterally, as this posture is burdensome and difficult to maintain, leading to movement of the treatment site during treatment.
Innovation Solution
A particle beam treatment system with a placement section and an irradiation section that fixes patients in a lateral position using a support member, allowing for accurate irradiation by maintaining the treatment site close to the irradiation section and minimizing movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the patient is positioned in lateral position for irradiation, then the treatment site can be disposed close to the irradiation section, but the patient's posture becomes burdensome and difficult to maintain, leading to movement of the treatment site
Solution Approach 1:
A support member is introduced as an intermediary device between the patient and the treatment bed. This support member provides mechanical assistance to maintain the patient's lateral position, enabling the patient to sustain the required posture without excessive burden while ensuring the treatment site remains accurately positioned near the irradiation section throughout the treatment process
2Reliability
If the patient is fixed in lateral position using support member, then the treatment site movement is minimized, but the device complexity increases
Solution Approach 1:
The support member is divided into multiple functional segments including a body support portion, a head support portion, and a positioning mechanism. Each segment performs a specific function, allowing the overall system to achieve reliable treatment site stability while keeping individual components simple and manageable

AI summary
A particle beam treatment system includes a placement section for placing a patient to be irradiated with a particle beam, and an irradiation section that irradiates the patient placed on the placement section with the particle beam, in which the irradiation section irradiates the patient with the particle beam in a state where the patient placed on the placement section is fixed in a lateral position.
