Comparison of Methods for Tool Localization in Biological Tissue from 3D Ultrasound Data
In medical applications, miniature surgical instruments such as needles, or electrodes are introduced into human body. The position of instrument in tissue can be estimated using 3D ultrasound. In previous publications, ...
Radial Radon Transform dedicated to Micro-object Localization from Radio Frequency Ultrasound Signal
In this paper we describe a method for automatic electrode localization in soft tissue from a radiofrequency signal. The method exploits a property of the Radon transform (RT) that allows us to localize a line-segment in ...
Parallel integral projection transform for straight electrode localization in 3-D ultrasound images
In surgical practice, small metallic instruments are frequently used to perform various tasks inside the human body. We address the problem of their accurate localization in the tissue. Recent experiments using medical ...
