Magnetic resonance imaging (MRI) can illuminate gross anatomy and pathology without the need for dissection. However, post-mortem tissues suffer from relatively poor signal contrast and increased vascular porosity compared to living tissues. While clinical contrast agents enhance antemortem imaging, few have been optimized for post-mortem magnetic resonance (PMMR) imaging. Here, we systematically evaluated several simple and effective solutions as post-mortem fiducial markers and intravascular injection contrast agents. They demonstrated gadolinium concentration-dependent hyperintensity in several MRI sequences applied to gel phantoms and cadavers. The addition of gelatin increased hyperintensity and prevented vascular leakage. Ultimately, fiducial markers and post-mortem intravascular contrast provide validation for newly seen anatomy on high-resolution PMMR which can inform clinical practice.","PeriodicalId":72237,"journal":{"name":"Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

However, the contrast variation across diffusion-weighted images complicates direct registration. To surmount this challenge, our study introduces a translation-based registration approach, utilizing 312 DTI datasets from the Human Connectome Project (HCP), including both b=0 and b=2000 volumes. We employed an advanced 3D Self-Attention Conditional Generative Adversarial Network (SC-GAN) for the synthesis of imaging data. This method allowed for the generation of synthesized b=2000 volumes, enhancing the distortion-correction process by facilitating efficient registration of distorted images. The results showed the translation network's effectiveness in synthesizing b=2000 volumes from real data, with these volumes serving as stable registration targets, particularly in limited directional data scenarios. The approach also effectively corrected eddy current and motion artifacts, aligning FA and FOD maps with gold standard results from FSL's eddy method, confirming the translation-based registration's efficacy in addressing cross-contrast registration challenges in DTI preprocessing.","PeriodicalId":72237,"journal":{"name":"Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

A reliable fingerprint recognition system can be a practical solution to address this issue. However, the scarcity of longitudinal fingerprint datasets for young children leads to unresolved questions regarding the earliest age for fingerprint biometric use, the frequency of enrollment required for reliable recognition, and the methods to accommodate age-related changes. A few recent studies introduced high-resolution fingerprint scanners and showed promising recognition performance for young children. However, these studies were conducted on a small dataset over a shorter period with limited diversity; further evaluation of their finding is essential. This study assessed the effectiveness of a high-resolution contactless scanner in a controlled, diverse longitudinal dataset of children (0-15 years). Our results indicate that infants can be enrolled at five days old and reliably recognized after two months with a TAR= 100% @ FAR = 0.1%, and children aged 4-15 years can be recognized after one year with a TAR= 98.72% @ FAR = 0.1%.","PeriodicalId":72237,"journal":{"name":"Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

However, achieving targeted and precise modulation with ultrasound poses a significant challenge. A hypothesis is that mechanosensitive (MS) ion channels may play a pivotal role in achieving the desired specificity in ultrasound effects. Our study involved augmenting MscL-G22S channel expression in specific areas of rats' hippocampus (HP) and primary visual cortex (V1) via AAV virus delivery. We recorded local field potentials (LFPs) to assess the modulation effect and identified distinct evoked-related potentials (ERPs) in regions overexpressing MscL-G22S channels under anesthesia. Notable variations in the amplitude of negative peaks were observed in the ERPs between HP and V1, highlighting a nuanced response to ultrasound stimulation. These results highlight the complexity and promise of MS channel-mediated neuromodulation, offering critical insights into the development of targeted ultrasound interventions to improve brain function.","PeriodicalId":72237,"journal":{"name":"Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

Motor imagery (MI) is one of the BCI paradigms for controlling external devices by imagining muscle movements. MI-based EEG signals generally tend to contain signals with sparse MI characteristics (sparse MI signals). When conducting domain adaptation (DA) on MI signals with sparse MI signals, it could interrupt the training process. In this paper, we proposed the proxy-based masking module (PMM) for masking sparse MI signals within MI signals. The proposed module was designed to suppress the amplitude of sparse MI signals using the negative similarity-based mask generated between the proxy of rest signals and the feature vectors of MI signals. We attached our proposed module to the conventional DA methods (i.e., the DJDAN, the MAAN, and the DRDA) to verify the effectiveness in the cross-subject environment on dataset 2a of BCI competition IV. When our proposed module was attached to each conventional DA method, the average accuracy was improved by much as 4.67 %, 0.76 %, and 1.72 %, respectively. Hence, we demonstrated that our proposed module could emphasize the information related to MI characteristics. The code of our implementation is accessible on GitHub.1.","PeriodicalId":72237,"journal":{"name":"Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

The bioink exhibited high water absorption and adequate rheology, enabling successful bioprinting of scaffolds with robust structures. The scaffolds remained stable for 24 hours, allowing prolonged bacterial growth. L. lactis viability was confirmed by confocal microscopy, which revealed green fluorescence indicative of live bacteria even after 8 hours of culture within the scaffold. This suggests a supportive microenvironment for bacterial survival and potential proliferation. Compared to a 2D model, the 3D scaffold increased the number of colony-forming units (CFUs), indicating a more supportive environment for L. lactis growth.

Participants in the alignment task performed tasks in which they aligned an object with a target position in virtual space using our developed interface while we measured the participant's operational performance and brain activation using functional near-infrared spectroscopy. We performed fitting using quadratic functions with the parameters of each model as design variables.
