Solution Overview

Problem

Current radiation therapy systems require separate equipment for treatment delivery and quality assurance, leading to inefficiencies in time, cost, and data transfer, with no integrated solution for simultaneous quality assurance and treatment delivery.

Innovation Solution

An automated system integrating a Radiation Field Analyzer (RFA) with radiation therapy equipment, featuring three-axis modules and a three-dimensional phantom for performing data dosimetry operations, allowing for permanent or detachable integration and automated control via a singular user interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If separate treatment delivery equipment and quality assurance equipment are used independently, then each equipment can be optimized for its specific function, but it results in wastage of time and effort in configuring equipment and requires sequential usage

Engineering Contradiction:
Improvequality assurance accuracyVSAvoidequipment configuration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines the radiation therapy treatment delivery equipment and the radiation field analyzer (quality assurance equipment) into a single integrated system. The RFA is positioned within the treatment delivery equipment's radiation path, allowing both treatment and quality assurance functions to be performed by the same hardware without sequential setup or data transfer between separate devices.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If separate treatment delivery equipment and quality assurance equipment are employed individually, then specialized testing can be performed, but the cost becomes extremely high

Engineering Contradiction:
Improvepatient treatment safetyVSAvoidequipment cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The integrated system allows the same radiation therapy equipment to serve dual purposes: delivering treatment to patients and performing quality assurance measurements. The radiation field analyzer shares the radiation source and detection infrastructure with the treatment delivery system, eliminating the need for separate specialized testing equipment while maintaining measurement reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If data is transferred from quality assurance equipment to treatment delivery equipment, then treatment planning can be performed, but the process becomes laborious and risky

Engineering Contradiction:
Improvetreatment planning convenienceVSAvoiddata transfer accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

By integrating the radiation field analyzer directly into the treatment delivery equipment, the system eliminates the data transfer interface between separate devices. The integrated system shares common control software, coordinate systems, and calibration references, thereby removing the laborious and error-prone manual or electronic data transfer process while maintaining full treatment planning capabilities.

Inventive Principle:
Principle #5Merging (Combining)
