“…This was the entry point of fUltrasound in the neuroimaging field, with a large scope of preclinical applications in both anesthetized and awake animals ( Figure 1E): studies has been conducted on the rat olfactory tract (B. F. ), visual system (Gesnik et al, 2017, spatial representation , visual system of the pigeon (Rau et al, 2017), auditory system of the ferret (Demené et al, 2016). In most of these animal studies a thinned skull surgery or a trepanation was needed to enable the penetration of the ultrasound waves, and the first-in-human proof-of-concept (Imbault et al, 2017) used a similar approach to circumvent the obstacle of the thick human skull ( Figure 1F).…”

The emergence of functional neuroimaging has dramatically accelerated our understanding of the human mind. The advent of functional Magnetic Resonance Imaging paved the way for the next decades' major discoveries in neuroscience and today remains the "gold standard" for deep brain imaging. Recent improvements in imaging technology have been somewhat limited to incremental innovations of mature techniques instead of breakthroughs. Recently, the use of ultrasonic plane waves transmitted at ultrafast frame rates was shown to highly increase Doppler ultrasound sensitivity to blood flows in small vessels in rodents. By identifying regions of brain activation through neurovascular coupling, Ultrafast Doppler was entering into the world of preclinical neuroimaging. The combination of many advantages, including high spatio-temporal resolution, deep penetration, high sensitivity and portability provided unique information about brain function. Ultrafast Recently, Ultrafast Doppler imaging was found able to non-invasively image the spatial and temporal dynamics of microvascular changes during seizures and interictal periods with an unprecedented resolution at bedside. This review summarizes the technical basis, the added value and the clinical perspectives provided by this new brain imaging modality that could create a breakthrough in the knowledge of brain hemodynamics, brain insult, and neuroprotection.

“…In [19], one transducer was rotated by 18 angles and translated by 65 steps at each angle to produce an integral 3D power Doppler volume, which is approximately characterized by an isotropic 3D Point-Spread-Function (PSF). This technique has been used for brain functional imaging [20], [21] and detecting the vascularity of tumor angiogenesis [22]. Although this method can provide improved and isotropic spatial resolution in 3D power Doppler, iterative translation and steering of the probe consume extended time to make it mainly feasible for relative stationary subjects like the brain and fixed tumor lesions.…”

The introduction of ultrafast ultrasound and spatiotemporal filtering has significantly improved the sensitivity of Doppler ultrasound imaging. This work describes the development of a 3D power Doppler imaging technique which uses a 1D-array ultrasound probe that mechanically translates at a constant speed. The continuous translation allows for a fast scan of a large 3D volume without requiring complex hardware. The technique was realized in a prototype and its feasibility illustrated using phantom and in vivo kidney and breast lesion experiments. Although this 3D Doppler imaging technique is limited in some aspects, it enables power Doppler imaging of a large volume in a short acquisition time with less computational costs.
