Workflow GUI for Radiotherapy Stage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiation therapy systems are complex and inefficient, requiring extensive training due to cumbersome data presentation and user interfaces that divert operators' attention from the patient and machine, leading to errors and inefficiencies.
Innovation Solution
A workflow-oriented graphical user interface that segments data by treatment stages, allowing relevant information to be displayed on electronic devices near the radiotherapy machine, enabling operators to focus on the patient and machine without diverting attention, and a pendant system for easy control and navigation of treatment stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all radiotherapy data is displayed on a single screen at once, then the operator has access to complete information, but the interface becomes difficult to understand and follow, reducing operational efficiency
Solution Approach 1:
The graphical user interface is divided into multiple sequential pages, each corresponding to a specific treatment stage. This segmentation allows the interface to present comprehensive radiotherapy data in manageable portions, with each page displaying only the information relevant to the current treatment stage, thereby maintaining completeness while improving understandability.
Solution Approach 2:
The GUI dynamically transitions between different pages based on the treatment workflow progression. The interface adapts its content display according to the current treatment stage, showing different sets of data and controls appropriate for each phase of the radiotherapy process, making the system responsive to operational context.
2Loss of information
If the display screen is placed on a wall near the radiotherapy machine, then the operator can view data, but the operator must turn away from the patient and machine, interrupting the workflow and reducing efficiency
Solution Approach 1:
The display interface is moved from a fixed wall-mounted position to a portable electronic device that can be positioned in the treatment room. This dimensional change allows the operator to view the GUI at an ergonomic distance and angle while maintaining focus on the patient and machine, eliminating the need to turn away and interrupt the workflow.
3Adaptability or versatility
If conventional pendants with many input mechanisms are used, then the radiotherapy system can be controlled, but the complexity requires extensive training and increases the likelihood of errors
Solution Approach 1:
The electronic device serving as the GUI platform performs multiple functions: displaying treatment data, providing navigation controls, enabling machine control, and facilitating workflow management. This universal device replaces the specialized pendant with numerous buttons and switches, consolidating control functionality into a more intuitive interface while maintaining comprehensive system control capability.

AI summary
Disclosed herein are radiotherapy methods and systems that can display a workflow-oriented graphical user interface(s). In an embodiment, a method comprises retrieving, by a server, information from a radiotherapy file associated with a patient, the information comprising an alignment data of at least a treatment region of the patient; presenting, by the server, for display on a graphical user interface, an image corresponding to the patient positioned on a couch of a radiotherapy machine, the image comprising an overlay on a surface of the patient in the treatment region; and presenting, by the server, for display, a visually distinct revised overlay for at least a portion of the surface of the patient in the treatment region that matches, within a predetermined margin of error, the alignment data.
