This study examines the performance of a simple microwave beamforming method using the Huygens scattering principle (called here the Huygens principle method) for detecting breast lesions. The beamforming method is similar to non-iterative time rever

Passive acoustic mapping (PAM) is a promising imaging method that enables real-time three-dimensional monitoring of ultrasound therapy through the reconstruction of acoustic emissions passively received on an array of ultrasonic sensors. A passive be
The accuracy of treatment monitoring and planning is instrumental to the acceptance of HIFU surgery. The ability to locate, analyze and track a feature of interest during treatment will be affected by patient motion. Additionally, statistical analysi

Temperature is the most critical parameter for controlling tissue ablation through HIFU. In this paper we introduce a new method to improve temperature estimation from ultrasound images taken during treatment. The most common way to monitor temperatu

This work is concerned with the automatic characterisation and classification of seabed sediments by using wavelet transform techniques to analyse the incoming one-dimensional signals from both sidescan and sidescan bathymetric sonars. This method ex

The authors present a technique for making use of both sidescan amplitude and bathymetric data provided from sidescan bathymetric sonars for the classification of underwater seabeds. Sidescan amplitude is corrected for physical factors and used to pl

In ultrasound-guided high-intensity focused ultrasound (HIFU) therapy, the changes observed on tissue are subtle during treatment; some ultrasound-guided HIFU protocols rely on the observation of significant brightness changes as the indicator of tis

Sonar is a popular sensor for robotic guidance, particularly for obstacle avoidance and for mapping. It has been used too for classifying objects and different surfaces. In this paper, we investigate further its use for surface classification. We dis

This paper proposes a new method to display microwave images of breast tissue, based on estimation of local microwave velocity from time of ∞ight measurements. Its computational demands are low compared with tomography. It has two major components:

It is widely accepted that rigorous rehabilitation exercises after a stroke can help restore some functionality. However for many patients, this means exercises at home with minimal, if any, clinician support. Technologies that help motivate and prom
