Towards a Simple Framework of Skill Transfer Learning for Robotic Ultrasound-guidance Procedures
This addresses skill transfer for robotic ultrasound procedures, but it is incremental as it builds on existing concepts with limited experimental validation.
The paper tackles skill transfer learning for robotic ultrasound-guidance procedures by proposing a simple framework, with pilot experiments showing that an experienced clinician performed quicker and smoother movements compared to a non-clinician.
In this paper, we present a simple framework of skill transfer learning for robotic ultrasound-guidance procedures. We briefly review challenges in skill transfer learning for robotic ultrasound-guidance procedures. We then identify the need of appropriate sampling techniques, computationally efficient neural networks models that lead to the proposal of a simple framework of skill transfer learning for real-time applications in robotic ultrasound-guidance procedures. We present pilot experiments from two participants (one experienced clinician and one non-clinician) looking for an optimal scanning plane of the four-chamber cardiac view from a fetal phantom. We analysed ultrasound image frames, time series of texture image features and quaternions and found that the experienced clinician performed the procedure in a quicker and smoother way compared to lengthy and non-constant movements from non-clinicians. For future work, we pointed out the need of pruned and quantised neural network models for real-time applications in robotic ultrasound-guidance procedure.
