The image degradations were modeled as a serialization of three processes accounting for the effects of defocus, speckle noise, and digital sampling in OCT images. An analytical model for light-propagation model and a statistical model for speckle noise were derived based on the physical properties of the OCT setup. These models were then integrated with a diffusion model to reverse the degradations caused by defocus blur and digital sampling, minimizing susceptibility to noise and defocus-induced artifacts.Results: The proposed method was employed for reconstructing images of a standard resolution target, plant tissue, and in vivo human cornea, using the complex OCT data acquired with a line-scan OCT (LS-OCT) system. The results from the PIDM exhibit improved sharpness and contrast compared to the images resulting from a few baseline methods such as standalone super-resolution using DM.Conclusion: Complementing DM with the physics of OCT could be a viable solution for obtaining high-fidelity SR reconstruction of OCT images.Significance: This work harnesses the power of diffusion models for super-resolution in OCT images. Such development could potentially enhance cellular-resolution OCT imaging of ophthalmic tissues, where high-fidelity images are crucial for accurate diagnosis.","PeriodicalId":13245,"journal":{"name":"IEEE Transactions on Biomedical Engineering","volume":"PP ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143763925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a multi-channel real-time decomposition algorithm based on a Hidden Markov Model of EMG and a Bayesian filter to estimate the spike trains of motor units (MUs) and their action potentials (MUAPs). The multi-channel framework of Bayesian modelling and filtering was implemented into parallel computation using multiple GPU clusters, which ensures computational speed compatible with real-time decomposition. A decomposed-checked channel strategy is then proposed for arranging channels into groups to be processed in related GPU clusters. The algorithm was validated on six 16-channel simulated signals, three 32-channel experimental signals acquired from the human tibialis anterior muscle, and two 16-channel experimental signals acquired from the abductor digiti minimi muscle with thin-film implanted electrodes. All signals were decomposed in real time with an average decomposition accuracy 90%. In conclusion, the proposed multi-channel iEMG decomposition algorithm can be applied to implanted multi-channel electrode arrays to establish human-machine interfaces with high-information transfer.","PeriodicalId":13245,"journal":{"name":"IEEE Transactions on Biomedical Engineering","volume":"PP ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143763087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, bioluminescence has been extensively used as a reporting agent in various biophotonics applications. However, its potential as a light source has not been explored. In this study, we propose the use of wireless Aequorin-based illumination as a bioinspired light-emitting source within biological tissue. This approach can have applications in a range of technologies; from optogenetics to bio-optical communications to human-brain interfaces. Drawing inspiration from the natural bioluminescent properties found in marine organisms, we designed a wireless Aequorin-based bioluminescence unit and developed an equivalent circuit model to describe the biological processes involved in illumination. Our model predicts the behavior of the bioluminescent units under various physical conditions, offering a framework for understanding how variations in physical parameters influence luminescence characteristics. In the absence of experimental studies focusing on Aequorin-based bioluminescence as a light source, our findings provide valuable guidance for researchers. These insights can help in understanding the system's behavior, designing more complex bioluminescence systems composed of multiple illumination units, and selecting parameters for future experimental research.","PeriodicalId":13245,"journal":{"name":"IEEE Transactions on Biomedical Engineering","volume":"PP ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143763927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that general anesthetic induced unconsciousness is related to interruption of thalamocortical connectivity. However, the neural mechanism of how anesthesia levels influence cortical responses during ultrasound thalamus stimulation has never been explored yet. And it remains unknown what cortical responses signatures are evoked by ultrasound thalamus stimulation under different anesthesia levels.Methods: We recorded multichannel electrocorticogram (ECoG) evoked by ultrasound thalamus stimulation of rats at various isoflurane concentrations (i.e., 0.5%, 1.0%, 1.5%, and 2.0% (v/v)). We analyzed ECoG signatures in temporal, spatial, and frequency domains by using the ultrasound-evoked potentials (UEPs), omega complexity (OC), and phase amplitude coupling (PAC), respectively.Results: The pattern of UEPs was influenced by the anesthesia level, and the response amplitude of UEPs increased with the increase in anesthesia level (0.5% vs. 1.0% and 1.5% (v/v), p<0.05). . Also, the OC of stimulated ECoG decreased with the increase in anesthesia level (at the 1.0%, 1.5% and 2.0% (v/v), p<0.05). and the modulation index of PAC was anesthesia level-dependent.Conclusion: The cortical response induced by ultrasound thalamus stimulation is related to the anesthesia level.

Usability was assessed using the System Usability Scale (SUS), and workload was measured with the NASA-TLX. Qualitative feedback was also collected to explore surgeon perceptions, and analysed thematically. Histopathological analysis was conducted to assess tissue integrity following instrument interaction. The PAF rail achieved SUS scores exceeding the good usability threshold, particularly among urology surgeons. However, its use was associated with increased cognitive load and longer task completion times, especially for less experienced surgeons.

Our first contribution is defining a baseline problem based on Murray's original formulation, which accommodates efficient solution algorithms. The problem of finding the global minimum is cast into a nonlinear optimization problem (NLP) with merely super-linear solution effort.

We test our framework against a benchmark of an anatomic region of brain tissue and a vasculature of the human liver.Results: In all cases, the total tree energy is improved significantly compared to local approaches.Conclusion: By avoiding intersections globally, we can reproduce key physiological features such as parallel running inflow vessels and tortuous vessels.Significance: The ability to generate non-intersecting vascular trees inside nonconvex organs can improve the functional assessment of organs.","PeriodicalId":13245,"journal":{"name":"IEEE Transactions on Biomedical Engineering","volume":"PP ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143730004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
