Radiotherapy Plan Sequencing for Single-Session Radiation Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiotherapy systems lack the capability to efficiently control the delivery of multiple treatment plans for a patient in a single session, requiring multiple control executions for each plan, which is inefficient and time-consuming.
Innovation Solution
A method for controlling radiation delivery that involves acquiring multiple treatment plans for a patient and sending control instructions in a preset order to execute these plans sequentially, utilizing a computer device with processors and memory to manage the radiotherapy equipment, including setup and radiation delivery instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple treatment plans are executed sequentially using traditional control methods, then each plan can be delivered with proper setup and monitoring, but the total treatment time increases and equipment utilization efficiency decreases
Solution Approach 1:
The system performs preliminary actions by acquiring and validating multiple treatment plans in advance, determining their delivery order before actual radiation delivery begins. This allows setup and verification to be completed beforehand, reducing wait time during treatment execution.
Solution Approach 2:
The patent implements continuous action by enabling seamless transitions between multiple treatment plans without requiring full system re-initialization. The control system maintains continuous operation state, allowing radiation delivery to proceed continuously across multiple plans once setup is complete.
2Ease of operation
If traditional control systems execute one treatment plan at a time with full setup procedures, then each plan receives adequate preparation and execution, but the number of control executions increases and operational efficiency decreases
Solution Approach 1:
The patent merges multiple treatment plan executions into a single control session. The system combines multiple plans into one unified delivery order sequence, allowing all plans to be executed under one control execution rather than requiring separate control procedures for each plan.
Solution Approach 2:
The control system achieves multi-functionality by designing a universal control mechanism that can handle multiple different treatment plans within a single execution. The system validates and delivers various types of treatment plans using the same control framework, eliminating the need for plan-specific control procedures.
3Manufacturing precision
If radiotherapy equipment performs complete setup procedures for each treatment plan, then positioning accuracy is maintained, but setup time accumulates across multiple plans
Solution Approach 1:
The system performs patient positioning and setup in advance before radiation delivery begins. By completing setup procedures preliminarily and determining the delivery order of multiple plans beforehand, the system avoids repeated setup actions for each subsequent plan.
Solution Approach 2:
The patent introduces dynamic adaptability by allowing the system to adjust its behavior based on whether this is the first plan or a subsequent plan. The control logic dynamically determines whether to execute full setup procedures or to proceed directly to radiation delivery based on the plan sequence and previous execution state.
