Developments in target micro-doppler signatures analysis: radar imaging, ultrasound and through-the-wall radar [PDF]
, 2013 Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

Efficacy of Cranial Doppler ultrasound in Diagnosis of Early-onset neonatal sepsis [PDF]
Al-Azhar International Medical Journal, 2021 Background: Neonatal sepsis is considered a major neonatal issue and associated with a high rate of mortality in newborns. Because there is a lack of studies concerning early hemodynamic changes of cerebral circulation in neonatal sepsis, so our research

Transcranial Doppler ultrasound [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1999 Transcranial Doppler ultrasound allows measurements of blood flow velocity to be made from the basal intracerebral vessels. The major advantages of transcranial Doppler ultrasound are that it is non-invasive, relatively cheap, can be performed with portable machines, allows monitoring for prolonged periods, and has a high temporal resolution making it ...

Stimulus rate increases lateralisation in linguistic and non-linguistic tasks measured by functional transcranial Doppler sonography. [PDF]
, 2015 Studies to date that have used fTCD to examine language lateralisation have predominantly used word or sentence generation tasks. Here we sought to further assess the sensitivity of fTCD to language lateralisation by using a metalinguistic task which ...
