Apparatus for mapping a surface of a cavity within a body of a subject includes an elongate probe, having a longitudinal axis and including a distal portion adapted for insertion into the cavity. A primary acoustic transducer on the distal portion of the probe is adapted to emit acoustic waves...
Real-time volume ultrasound imaging of the heart is a new trend, and the registration of acquired volume framesets is clinically important. This registration may be accomplished by processing a selected pair of volume frames having identical cardiac phase (preferably end diastolic) from two frameset...

Fast cardiac imaging requires a reduction of the number of transmit events. This is typically achieved through multi-line-transmission (MLT) and/or multi-line-acquisition (MLA) techniques. However, restricting the field-of-view (FOV) to the anatomically relevant domain, e.g. the myocardium, can...
Summary The purpose of this study is to assess the reliability of a new ultrasound imaging (USI) parameter and procedure for the evaluation of the size of the deep cervical flexor (DCF) muscles. Thirty-one healthy male subjects (21.6 ± 2.5 years old) participated in this study. Two images...
Objective: The objective of this study was to investigate the feasibility of examining the fetal heart with Tomographic Ultrasound Imaging (TUI) using four-dimensional (4D) volume datasets acquired with spatiotemporal image correlation (STIC). Material a
Often, Monte Carlo simulations or absolute range measurement of the particle beam allow for an accurate treatment plan. Nonetheless, this approach is typically only applicable offline and remains theoretical18,19. Prompt gamma imaging and positron emission tomography (PET) have been proposed as ...
