Mashup Score: 5Site-specific effects of 800- and 850-nm forehead transcranial photobiomodulation on prefrontal bilateral connectivity and unilateral coupling in young adults - 11 month(s) ago
SignificanceTranscranial photobiomodulation (tPBM) is a noninvasive neuromodulation method that facilitates the improvement of human cognition. However, limited information is available in the literature on the wavelength- and site-specific effects of prefrontal tPBM. Moreover, 2-channel broadband near-infrared spectroscopy (2-bbNIRS) is a new approach for quantifying infra-slow oscillations…

Mashup Score: 2Bioinspired color-near infrared endoscopic imaging system for molecular guided cancer surgery - 12 month(s) ago
SignificanceFluorescently guided minimally invasive surgery is improving patient outcomes and disease-free survival, but biomarker variability hinders complete tumor resection with single molecular probes. To overcome this, we developed a bioinspired endoscopic system that images multiple tumor-targeted probes, quantifies volumetric ratios in cancer models, and detects tumors in ex vivo…

Mashup Score: 3Effects of formalin fixation on polarimetric properties of brain tissue: fresh or fixed? - 12 month(s) ago
SignificanceImaging Mueller polarimetry (IMP) appears as a promising technique for real-time delineation of healthy and neoplastic tissue during neurosurgery. The training of machine learning algorithms used for the image post-processing requires large data sets typically derived from the measurements of formalin-fixed brain sections. However, the success of the transfer of such algorithms from…

Mashup Score: 8Towards fracture risk assessment by deep-learning-based classification of prevalent vertebral fractures - 1 year(s) ago
Osteoporosis is a complex multifactorial skeletal disease and has become a major socioeconomic issue, causing tremendous hospitalization and rehabilitation costs. In addition to age, premature menopause or the use of oral corticosteroids, vertebral fractures are regarded as main risk factors for developing osteoporosis and associated fractures. In this work, we adapt an existing automated…

Mashup Score: 9Imaging the vasculature of a beating heart by dynamic speckle: the challenge of a quasiperiodic motion - 1 year(s) ago
The spatial and temporal evolution of the field backscattered by a beating heart while illuminated with a coherent light reveals its macro- and microvascularization in real time. To perform these vascularization images, we use a recently published method of laser speckle imaging, based on the selective detection of spatially depolarized speckle field that is mainly generated by multiple…

Mashup Score: 0Predicting cell type counts in whole slide histology images using evidential multi-task learning - 1 year(s) ago
Predicting the presence and counting various cell types in the tumor micro-environment is crucial for identifying cell spatial and morphological features in computational pathology. Deep learning (DL) approaches have been used extensively in predicting and counting different cell types in whole slide images (WSIs). However, DL-based probabilistic approaches have limitations in classifying pixels…

Mashup Score: 9Enhancing intraoperative tumor delineation with multispectral short-wave infrared fluorescence imaging and machine learning - 1 year(s) ago
SignificanceFluorescence-guided surgery (FGS) provides specific real-time visualization of tumors, but intensity-based measurement of fluorescence is prone to errors. Multispectral imaging (MSI) in the short-wave infrared (SWIR) has the potential to improve tumor delineation by enabling machine-learning classification of pixels based on their spectral characteristics.AimDetermine whether MSI can…
