Clinical Scorecard: Strategic Planning of Acoustic Windows for Ultrasound Imaging Acquisition

At a Glance

Key Highlights

• Introduction of a novel planning framework for autonomous 2D and 3D ultrasound acquisitions integrating geometrical, anatomical, and imaging physics constraints.
• Use of preoperative tomographic data (CT, MRI) to estimate ultrasound attenuation and optimize acoustic windows for target structures.
• Robotic ultrasound imaging can reduce operator variability and enable reproducible, precise data acquisition for longitudinal and interventional studies.

Guideline-Based Recommendations

Diagnosis

• Employ ultrasound imaging as a fundamental modality for chronic liver diseases and other organ assessments.
• Use preoperative imaging (CT, MRI) to define target points for ultrasound acquisition planning.

Management

• Plan ultrasound probe trajectories in 3D considering probe position, orientation, and anatomical constraints to optimize image quality.
• Incorporate acoustic attenuation estimates into planning to select optimal acoustic windows avoiding bones and other artifacts.

Monitoring & Follow-up

• Utilize robotic ultrasound systems to ensure reproducible and precise acquisition for longitudinal monitoring.
• Apply ultrasound confidence maps during acquisition to estimate image quality, though these are limited to real-time use.

Risks

• High operator variability in ultrasound imaging can reduce reproducibility and image quality.
• Improper probe positioning may cause acoustic shadowing, reverberations, and poor image quality.

Patient & Prescribing Data

Patients undergoing ultrasound imaging for liver, heart, or other organs with complex acoustic windows

Automated planning and robotic execution of ultrasound acquisitions can improve image quality and reproducibility, facilitating better diagnosis and intervention.

Clinical Best Practices

• Use preoperative tomographic imaging to guide ultrasound probe placement planning.
• Consider both 2D and 3D ultrasound acquisition trajectories for comprehensive imaging.
• Integrate anatomical constraints and ultrasound physics (attenuation, acoustic coupling) into probe position optimization.
• Employ robotic ultrasound systems to reduce operator-dependent variability and improve acquisition consistency.
