“…Technical solutions for correction of skull irregularities are currently under investigation [63]. Moreover, 3-D techniques and computer-aided image analysis might reduce the dependence of the method on investigators’ skills [64,65,66], and 3-D ultrasound probes may also increase the diagnostic window from the transtemporal approach.…”

In acute stroke, different sonographic methods can be used to assess structural and hemodynamic compromise. Structural abnormalities of brain parenchyma such as primary intracerebral hemorrhage (ICH) and epiphenomena such as midline shift can be detected by native transcranial B-mode ultrasound. Moreover, transcranial Doppler provides a functional approach to intracranial hemodynamics and may assist in predicting ICH growth and global intracranial pressure increase. New ultrasound technologies allow the visualization of ultrasound contrast agents in the cerebral microcirculation. According to recent data, ultrasound perfusion imaging provides additional information for the diagnosis of ICH and may differentiate ischemic from hemorrhagic stroke. This review summarizes the impact of these different transcranial ultrasound methods on diagnosis and monitoring of ICH.

“…Advanced reconstruction based on non-rigid registration and radial basis functions interpolation has been proposed for 3D ultrasound images [51]. For an arbitrary-shape blanket, reconstruction algorithms should incorporate transducer trajectory information to enable a more precise reconstruction [52].…”

Bulk piezoelectric ceramics and single crystals are widely used in medical applications, including medical ultrasonic imaging, therapeutic ultrasound, and drug delivery. This paper reviews possibilities for thin film micromachined components as alternatives to the bulk devices. Particular emphasis is placed on the development of a CMOScompatible ultrasound system. For this purpose, a piezoelectric ultrasound system on a Si substrate was fabricated using a diaphragm geometry transducer with PZT films. A 1-D array of 8 elements was designed and fabricated using 4 photolithography steps. Cavities under the resonating elements were obtained by XeF 2 etching from the top-side of the wafer. Capacitance and admittance spectra showed a resonance at ∼ 42 MHz for the fabricated structures with a quality factor of 2.1, this resonance was higher than the one predicted by the natural frequency equation for circular plate. Catch-and pitch-mode tests were performed in water. Sensing and actuating functionalities were demonstrated for the fabricated devices, with collected signals of 40 mV peak-to-peak at a distance of 7.2 mm during the catch-mode test and amplitudes as high as 15 mV peak-to-peak at a distance of 7.4 mm during the pitch-mode test. A bandwidth of 83% was calculated during pitch-mode test.

“…1). Intraoperative stage : Before opening the dura the first 3D freehand US sequence acquired on the dura was reconstructed [10] and denoised [11]. Then, the preoperative MR image was re-sliced into the US coordinate system thanks to the transformation matrix provided by the neuronavigation system (see top-left in Fig.…”

“…As it is generally admitted, we assume that no significant brainshift occurs before opening of the dura. This paper proposes a general framework designed for brainshift compensation built on previous works on 3D reconstruction of freehand US [10], denoising of US images [11] and rigid registration of US and MR images [9].…”

In this paper, a global approach based on 3D freehand ultrasound imaging is proposed to (a) correct the error of the neuronavigation system in image-patient registration and (b) compensate for the deformations of the cerebral structures occurring during a neurosurgical procedure. The rigid and non rigid multimodal registrations are achieved by matching the hyperechogenic structures of brain. The quantitative evaluation of the non rigid registration was performed within a framework based on synthetic deformation. Finally, experiments were carried out on real data sets of 4 patients with lesions such as cavernoma and low-grade glioma. Qualitative and quantitative results on the estimated error performed by neuronavigation system and the estimated brain deformations are given.
