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…
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…
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…
