AI Article Synopsis
- A collimator design was developed to improve the precision of ultrasound stimulation for neuromodulation in mice, focusing on targeting specific brain areas.
- Three types of collimator designs were simulated to find the best one, with performance tested against unmounted collimators in both live and lab settings.
- The optimized collimator successfully shaped ultrasound waves, triggering neural activity in the motor cortex, indicating its effectiveness for targeted stimulation in small animal research.
Article Abstract
A collimator design was investigated to localize ultrasound stimulation using a flat ultrasound transducer for ultrasound-induced neuromodulation in a mouse model. In brain stimulation, the specific location of stimulation must be specified, as the region responsible for motor or sensory function is clustered in a narrow brain area. To localize ultrasound stimulation, three types of collimator design were simulated to determine the optimal collimator design. The performance of the simulated optimal collimator was compared to that of an unmounted collimator in a transducer in both in vivo and in vitro experiments. Throughout the experiments, the localized ultrasound waveform was shaped using the optimized collimator, which elicited neural spike activity in the targeted motor cortex. The optimized collimator shows potential for controlling a localized ultrasound waveform for ultrasound-induced neuromodulation in a small animal model.

Investigating time-independent and time-dependent diffusion phenomena using steady-state diffusion MRI.

Diffusion MRI is a leading method to non-invasively characterise brain tissue microstructure across multiple domains and scales. Diffusion-weighted steady-state free precession (DW-SSFP) is an established imaging sequence for post-mortem MRI, addressing the challenging imaging environment of fixed tissue with short T and low diffusivities. However, a current limitation of DW-SSFP is signal interpretation: it is not clear what diffusion 'regime' the sequence probes and therefore its potential to characterise tissue microstructure.

Background: Management of respiratory motion during radiation therapy is essential for accurate dose delivery and minimizing the risk to organs. In diagnostic imaging, respiratory monitoring is required for confirmation of breath-hold and four-dimensional computed tomography (CT) reconstruction. Although respiratory monitoring systems are widely used in radiation therapy, they are not often used for diagnostic imaging, where they could improve image quality.

Purpose: To investigate the technique for dorsal median sulcus (DMS) mapping and assess its application value in preserving dorsal columnn (DC) function during intramedullary space occupying surgery based on a single-center experience.
Methods: A retrospective analysis was conducted on 41 cases of intramedullary spinal cord tumor admitted to the Department of Neurosurgery at the First Affiliated Hospital of Xiamen University from March 2017 to August 2023. All included cases underwent intraoperative electrophysiological monitoring, and were divided into a study group (n = 18) and a control group (n = 23), based on whether DMS mapping technique was utilized.
Portable six-channel laser speckle system for simultaneous measurement of cerebral blood flow and volume with potential applications in characterization of brain injury.

Significance: Cerebral blood flow (CBF) and cerebral blood volume (CBV) are key metrics for regional cerebrovascular monitoring. Simultaneous, non-invasive measurement of CBF and CBV at different brain locations would advance cerebrovascular monitoring and pave the way for brain injury detection as current brain injury diagnostic methods are often constrained by high costs, limited sensitivity, and reliance on subjective symptom reporting.
Aim: We aim to develop a multi-channel non-invasive optical system for measuring CBF and CBV at different regions of the brain simultaneously with a cost-effective, reliable, and scalable system capable of detecting potential differences in CBF and CBV across different regions of the brain.

Aims: To describe the sonographic features of active Charcot neuro-osteoarthropathy (CNO) and assess the potential role of ultrasound in identifying those with active CNO.
Methods: Using a prospective case-series study design we assessed the sonographic features of 14 patients with a diagnosis of diabetes presenting with clinical signs and symptoms suspicious for active CNO. Patients had standard weight-bearing plain X-Ray and, where possible, MRI to evaluate the presence of active CNO.
