The aim of this study was to develop a new, fully-automated approach for the extraction of arterial centerlines from whole-body computed tomography angiographic (CTA) data sets for the planning of transcatheter aortic valve replacement (TAVR) procedures by the transfemoral approach. The method starts with an image pre-processing step to correct contrast inhomogeneities in different image slices, followed...
A new-styled molecular hyperspectral imaging system (MHIS) based on acousto-optic tunable filter (AOTF) was introduced in this paper. This system consists of a Charge-coupled Device (CCD) camera, microscopy, AOTF, and a RF driver. Real-time images are obtained both at multiple, continuous wavelengths and at relatively narrow spectral bandwidths to generate a 3D data including one spectral and two...
Limited-diffraction beams have a large depth of field and could be applied to medical imaging, tissue characterization, and nondestructive evaluation of materials. This paper reports the application of limited-diffraction beams, specifically, the Bessel beam, to Doppler velocity estimation. The Bessel beam has the advantage that velocity estimation is less subject to the depth of moving objects and...
