“…In addition, the availability of haptic simulators (ie, with tactile and directional feedback) has made it possible to track manual skill acquisition objectively. 41,42 Utilization of a curriculum-based approach with online didactics has been shown to enhance cognitive knowledge, manual dexterity, and clinical transferability of simulator-acquired skills for POCUS modalities such as TTE and TEE. 41,42 Despite the perceived benefits of online didactics and simulation, there may be some potential limitations of using this educational approach.…”

“…Performance evaluation is a key element in interventional medicine and alternative, preferably automated, methods for evaluating TEE competency are necessary [14]. So far, objective assessment in TEE is focused exclusively on the kinematic analysis of the US probe with various motion parameters found to be indicative of the level of operational expertise [9,10]. Although these are important findings, probe kinematic information is not available in clinical settings and only captured in simulation systems.…”

Transoesophageal echocardiography (TEE) is a valuable diagnostic and monitoring imaging modality. Proper image acquisition is essential for diagnosis, yet current assessment techniques are solely based on manual expert review. This paper presents a supervised deep learning framework for automatically evaluating and grading the quality of TEE images. To obtain the necessary dataset, 38 participants of varied experience performed TEE exams with a high-fidelity virtual reality (VR) platform. Two Convolutional Neural Network (CNN) architectures, AlexNet and VGG, structured to perform regression, were finetuned and validated on manually graded images from three evaluators. Two different scoring strategies, a criteria-based percentage and an overall general impression, were used. The developed CNN models estimate the average score with a root mean square accuracy ranging between 84%-93%, indicating the ability to replicate expert valuation. Proposed strategies for automated TEE assessment can have a significant impact on the training process of new TEE operators, providing direct feedback and facilitating the development of the necessary dexterous skills.

“…laparoscopic, endovascular) that have reported a strong correlation between tool kinematics and surgical ability [5,7,10], we hypothesised that by analysing the motion pattern of the tip of the TEE probe (that carries the US transducer) and deriving representative metrics, surgical skills can be objectively evaluated. Thus far, basic probe kinematics have only been used to measure the improvement of trainees during training/teaching with simulators, but not for TEE skills assessment [4,11]. This work differs from such studies, which chiefly employ qualitative manual evaluation [2,11].…”

Abstract. This paper presents a novel approach for evaluating technical skills in Transoesophageal Echocardiography (TEE). Our core assumption is that operational competency can be objectively expressed by specific motion-based measures. TEE experiments were carried out with an augmented reality simulation platform involving both novice trainees and expert radiologists. Probe motion data were collected and used to formulate various kinematic parameters. Subsequent analysis showed that statistically significant differences exist among the two groups for the majority of the metrics investigated. Experts exhibited lower completion times and higher average velocity and acceleration, attributed to their refined ability for efficient and economical probe manipulation. In addition, their navigation pattern is characterised by increased smoothness and fluidity, evaluated through the measures of dimensionless jerk and spectral arc length. Utilised as inputs to well-known clustering algorithms, the derived metrics are capable of discriminating experience levels with high accuracy (>84%).
