IVUS Segment Mapping for Accurate Intraluminal Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intravascular ultrasound (IVUS) imaging systems face challenges in accurately determining and labeling key anatomical landmarks during procedures, requiring non-sterile staff to manually bookmark segments and frames, which is time-consuming and prone to errors, affecting treatment planning and recordkeeping.
Innovation Solution
The IVUS pullback virtual venogram system provides a processor circuit that identifies, displays, and records the location of an intravascular imaging probe within the vasculature, offering a stylized figure of the body lumen with segment markers, indicators, and automatic labeling, enhancing positional navigation and reducing staff dependency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual bookmarking of anatomical landmarks is performed by non-sterile staff, then the system can capture IVUS images during the procedure, but the process becomes time-consuming and prone to errors
Solution Approach 1:
The system enables self-service by allowing the sterile operator to capture IVUS images while the non-sterile operator independently performs bookmarking and labeling of anatomical landmarks without requiring direct interaction or coordination, with both operations occurring simultaneously on separate displays
Solution Approach 2:
A graphical representation of the body lumen with annotated landmarks serves as an intermediary that links the IVUS images captured by the sterile operator with the anatomical landmarks identified by the non-sterile operator, enabling accurate correlation without direct communication between operators
2Loss of information
If non-sterile staff manually label and measure segments, then detailed anatomical information can be recorded, but the workflow complexity and staff dependency increase
Solution Approach 1:
The system divides the workflow into separate functional segments: the sterile operator handles IVUS image capture on one display while the non-sterile operator handles landmark identification and labeling on a separate graphical representation, with each operator working independently on their designated task
Solution Approach 2:
The system provides multi-functionality by enabling both IVUS image display and anatomical landmark annotation capabilities within a single integrated system, allowing different operators to perform multiple functions simultaneously without requiring additional equipment
3Reliability
If accurate measurement and labeling are performed manually, then treatment planning can be optimized, but the tedious nature of the task reduces productivity
Solution Approach 1:
The system performs preliminary action by capturing and storing all IVUS images and anatomical landmark information during the procedure itself, so that post-procedure analysis can be performed more efficiently with pre-organized data rather than requiring manual review of raw images later
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system simplifies the correlation between IVUS frames and anatomy, saving time and improving accuracy in landmark identification, enabling efficient workflow and clearer medical records by automating the labeling process.

AI summary
Disclosed is an intraluminal ultrasound imaging system, comprising a processor circuit in communication with an intraluminal ultrasound imaging catheter, and configured to receive an intraluminal ultrasound image from the imaging catheter within a body lumen of a patient, the body lumen comprising a plurality of segments. The processor is configured to identify a segment of the plurality of segments where the imaging catheter was located when the image was obtained, and output to a display a stylized figure of the body lumen including the plurality of segments, and an indicator identifying the segment in the stylized figure where the imaging catheter was located when the image was obtained.
