Image Guidance System Single Setup Biopsy Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cancer-related clinical workflows are inefficient and costly due to the need for multiple hospital visits and redundant patient setups for biopsy and treatment procedures, which increase time and risk of errors.
Innovation Solution
An image guidance system that combines biopsy and treatment procedures, allowing for a single patient setup and using calibration settings from the biopsy procedure for treatment, with features like medical imaging, needle guidance, and user interface to streamline the process and reduce errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If biopsy and treatment procedures are performed separately with multiple patient setups, then each procedure can be optimized independently, but the total procedure time and hospital resource usage increases significantly
Solution Approach 1:
The patent combines biopsy and treatment procedures into a single integrated workflow. The needle guidance system is calibrated once to perform both biopsy sampling and subsequent treatment needle positioning, eliminating the need for separate patient setups and reducing total procedure time while maintaining optimization for both procedures through software coordination
2Measurement precision
If separate calibration is performed for biopsy and treatment, then each procedure achieves optimal accuracy, but the setup time and risk of calibration errors increases
Solution Approach 1:
The system performs a single preliminary calibration of the needle guidance system that establishes a unified coordinate system for both biopsy and treatment procedures. This preliminary calibration action ensures consistent accuracy across both procedures while eliminating the risks associated with multiple separate calibration processes
Solution Approach 2:
The calibration unit is designed with multi-functionality to serve both biopsy and treatment procedures through a single calibration process. The same calibration settings and coordinate system are universally applied to guide both biopsy needles and treatment needles, ensuring consistent precision across different procedural stages
3Loss of information
If multiple hospital visits are required for biopsy and treatment, then thorough evaluation and planning can be performed, but patient burden and hospital resource consumption increase
Solution Approach 1:
The system enables continuous workflow within a single hospital visit by maintaining the patient in the imaging and guidance system throughout both biopsy and treatment procedures. This continuity allows thorough diagnostic evaluation and treatment planning without breaking the workflow, eliminating the need for multiple visits while preserving diagnostic accuracy through continuous imaging and coordination

AI summary
It is an object of the invention to provide for a system that can be used to improve a cancer related clinical workflow compared to the current cancer related clinical workflow. This object is achieved by an image guided system configured for supporting a combined biopsy and treatment procedure using image guidance to bring a needle from a defined location to a predetermined end location in a subject of interest. The image guidance system comprises a medical imaging system (580) configured for acquisition of medical images of a region of interest (403) in the subject of interest, wherein the medical images are used to determine a current position of the predetermined end location (404). The image guidance system further comprises needle guidance system (402, 403) configured for defining a needle position in space and thereby defining the defined location (405, 406) and configured for guiding a biopsy and treatment needle into the region of interest. The image guidance system also comprises a user interface system (530) configured for supporting both the biopsy and treatment procedure, such that a patient setup needs to be executed only once. The user interface system (530) comprises a calibration unit (540) for aligning the needle guidance system (402, 403) with the medical images.
