Application of Linearization and Approximation

Application of Linearization and Approximation

A drone flying through complex terrain often relies on more than one sensing method to estimate small changes in altitude. Along with direct measurements, air pressure provides a useful indirect indicator of vertical movement. Atmospheric pressure decreases as altitude increases, and this relationship is commonly described using an exponential model. Although accurate, converting pressure measurements into altitude values requires calculations that are too complex to perform repeatedly during...

Medical Imaging
Artificial Intelligence
Ultrasound Technology

Background:

Standard planes (SPs) acquisition is vital in routine ultrasound (US) examinations.
3D US offers advantages over 2D US for capturing multiple SPs and visualizing specific planes.
SPs localization in 3D US is challenging due to search space, anatomical variability, and image quality.

Purpose of the Study:

To present a novel probabilistic method for standard plane localization in 3D ultrasound.
To enhance accuracy and efficiency in 3D US examinations.
To explore simultaneous SP localization and abnormality detection.

Main Methods:

Utilized a conditional denoising diffusion model for SP localization in 3D US.
Incorporated multi-scale guidance for global and local context.
Improved angular sensitivity using spherical coordinates and modified plane representation.

Main Results:

Achieved average errors below 10° (angle) and 1 mm (distance) for four SPs across two organs.
Demonstrated over 90% accuracy in anomaly detection by thresholding quantified uncertainty.
Validated on a large in-house dataset of 837 patients.

Conclusions:

The proposed method significantly outperforms state-of-the-art approaches in spatial and content metrics.
The method shows superiority and generalizability across different SPs and organs.
The integrated anomaly detection capability shows potential for clinical application.
