In this paper, we propose a new tomographic reconstruction method, called IOD-PVRMPP, to reconstruct 3D particle volumes from 2D particle images provided by the Tomographic Particle Image Ve-locimetry (Tomo-PIV) technique. Our method, based on marked point processes (or object processes), allows to solve the problem in a parsimonious way. It facilitates the introduction of prior knowledge and solves...
The need to further improve the spatial resolution of intravascular ultrasound (IVUS) may drive the transducer center frequency even higher than the current 40 MHz range. Using a higher frequency results in stronger scattering echoes from the blood and may hamper visualization of the arterial lumen. This paper presents a multi-frequency processing method to enhance the arterial lumen by extracting...
