Ultrasonic colour Doppler imaging [PDF]

Interface Focus, 2011
Ultrasonic colour Doppler is an imaging technique that combines anatomical information derived using ultrasonic pulse-echo techniques with velocity information derived using ultrasonic Doppler techniques to generate colour-coded maps of tissue velocity superimposed on grey-scale images of tissue anatomy. The most common use of the technique is to image

Spontaneous Aortic Thrombosis in a Neonate: A Rare Differential Diagnosis for Aortic Coarctation

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2021
Spontaneous aortic thrombosis is a serious clinical entity with clinical features that mimic neonatal coarctation of aorta. While both conditions manifest with weak femoral pulses, pallor and poikilothermia of lower limbs are unique to spontaneous aortic

Approximate Bayesian neural Doppler imaging [PDF]

Astronomy & Astrophysics, 2022
Aims. The non-uniform surface temperature distribution of rotating active stars is routinely mapped with the Doppler imaging technique. Inhomogeneities in the surface produce features in high-resolution spectroscopic observations that shift in wavelength because of the Doppler effect, depending on their position on the visible hemisphere. The inversion
