Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiotherapy treatments are compromised by the need for frequent reexamination and plan updates due to tumor growth or deformation during the lengthy planning process, reducing accuracy and efficiency.
Innovation Solution
A system and method involving an imaging device, positioning device, and treatment device, with a control device to generate and execute treatment plans based on real-time imaging and fixed object positioning, ensuring consistent alignment from start to end of treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the radiotherapy treatment plan determination and modification process is performed using conventional methods, then the treatment can be completed with standard procedures, but the patient needs to wait for a relatively long time during which the tumor structure may change, requiring frequent reexamination and plan updates
Solution Approach 1:
The system performs preliminary imaging and treatment plan generation before the patient leaves the treatment room. The imaging device captures images of the patient's tumor, and the control device generates a treatment plan based on these images while the patient is still positioned on the positioning device, eliminating the need for waiting and subsequent reexaminations.
Solution Approach 2:
The imaging and treatment plan generation processes are performed continuously without interrupting the patient's positioning. The system maintains the patient in a fixed position on the positioning device throughout the imaging and planning process, ensuring continuous and uninterrupted treatment preparation.
2Measurement precision
If frequent reexamination and plan updates are performed to maintain treatment accuracy, then the treatment precision can be improved, but the treatment time is prolonged and efficiency is reduced
Solution Approach 1:
The imaging device provides real-time feedback on the patient's tumor structure and position. The control device uses this feedback to generate and update treatment plans immediately, ensuring treatment accuracy without requiring multiple separate reexamination visits, thereby improving overall treatment efficiency.
3Ease of operation
If the patient is repositioned between imaging and treatment, then the imaging and treatment processes can be performed separately, but the positioning consistency is compromised and additional alignment time is required
Solution Approach 1:
The system merges the imaging device, positioning device, and treatment device into an integrated system. The patient remains on the positioning device throughout the imaging and treatment plan generation process, ensuring that the positioning is consistent and eliminating the need for repositioning or additional alignment procedures.

AI summary
The present disclosure may disclose methods and systems for treating an object. The method may include imaging an object fixed on a positioning device using an imaging device. The method may include obtaining a plan image of the object. The method may include generating information of a region of interest (ROI) of the object based on the plan image of the object. The method may include generating a treatment plan based on the information of the ROI. The treatment plan may include a plan isocenter on the plan image. The method may further include treating a target portion of the object based on the treatment plan using a treatment device. The object may be fixed on the positioning device from a moment that the object is started to fixed on the positioning device to an end of the treatment of the target portion.
