Multimodal Transformers for Real-Time Surgical Activity Prediction
Keshara Weerasinghe, Seyed Hamid Reza Roodabeh, Kay Hutchinson +1
Real-time recognition and prediction of surgical activities are fundamental to advancing safety and autonomy in robot-assisted surgery. This paper presents a multimodal transformer…
Towards Interpretable Motion-level Skill Assessment in Robotic Surgery
Kay Hutchinson, Katherina Chen, Homa Alemzadeh
Purpose: We study the relationship between surgical gestures and motion primitives in dry-lab surgical exercises towards a deeper understanding of surgical activity at fine-grained…
Evaluating the Task Generalization of Temporal Convolutional Networks for Surgical Gesture and Motion Recognition using Kinematic Data
Kay Hutchinson, Ian Reyes, Zongyu Li +1
Fine-grained activity recognition enables explainable analysis of procedures for skill assessment, autonomy, and error detection in robot-assisted surgery. However, existing recogn…
Towards Surgical Context Inference and Translation to Gestures
Kay Hutchinson, Zongyu Li, Ian Reyes +1
Manual labeling of gestures in robot-assisted surgery is labor intensive, prone to errors, and requires expertise or training. We propose a method for automated and explainable gen…
COMPASS: A Formal Framework and Aggregate Dataset for Generalized Surgical Procedure Modeling
Kay Hutchinson, Ian Reyes, Zongyu Li +1
Purpose: We propose a formal framework for the modeling and segmentation of minimally-invasive surgical tasks using a unified set of motion primitives (MPs) to enable more objectiv…
Runtime Detection of Executional Errors in Robot-Assisted Surgery
Zongyu Li, Kay Hutchinson, Homa Alemzadeh
Despite significant developments in the design of surgical robots and automated techniques for objective evaluation of surgical skills, there are still challenges in ensuring safet…
Analysis of Executional and Procedural Errors in Dry-lab Robotic Surgery Experiments
Kay Hutchinson, Zongyu Li, Leigh A. Cantrell +2
Background Analyzing kinematic and video data can help identify potentially erroneous motions that lead to sub-optimal surgeon performance and safety-critical events in robot-assis…
A Reactive Autonomous Camera System for the RAVEN II Surgical Robot
Kay Hutchinson, Mohammad Samin Yasar, Harshneet Bhatia +1
The endoscopic camera of a surgical robot provides surgeons with a magnified 3D view of the surgical field, but repositioning it increases mental workload and operation time. Poor…
