Biomedical Laser Technology

Minimally-invasive procedures result in less pain and quicker healing. Surgeons have used lasers to cauterize blood vessels and drill holes through the heart. Laser-based technology is the hub of the laser and digital evolution! Patients now have access to the best diagnostic tools. Indeed, the use and development of technology in the healthcare industry have become a necessity. Artificial intelligence (AI) offers various advantages exceeding traditional diagnostic and clinical techniques. AI technology advances the efficiency of care delivery and allows healthcare systems to offer superior care to patients through amalgamating information, producing time-saving administrative duties, increasing the efficiency of disease diagnosis, and decreasing unnecessary hospitalizations. In parallelism with improved digital technologies is the ability to analyze, share, and store health information. The secret of delivering valuable health- and social care lies in the successful application of these technologies. A new innovation of the healthcare industry is the remote monitoring of patients. The centralization of laboratory results and patient data has advanced the quality of healthcare. Medical technologies such as improved monitoring systems, comfortable scanning equipment, and less invasive surgeries allow the patient to waste less time in recovery and more time to enjoy a healthy life. It is essential that the health profession continues to develop technologies to cure diseases and advance the quality of life. Health informatics (the intersection of people, data, and technology to develop the quality of patient care) combines the fields of information, technology, medicine, and science. It includes the technological improvement of dentistry, pharmacy, and drug delivery. The world health organization (WHO) defines digital health literacy as the ability to understand electronic health information to solve health problems (WHO’s latest nursing report specifies the importance of technology in nursing education and practice). The American Library Association’s definition of digital literacy skills is the ability of both cognitive and technical skills to use information and communication technologies (ICTs) to discover, analyze, generate, and communicate information. The most important purpose of health informatics is to impart valuable healthcare and provide patients with vital information to share with clinicians, family, and friends. Healthcare institutions now use inter-hospital and intra-hospital communication methods.

The human-technology interface is the interaction between humans and technology; it is software and hardware such as computers, digital screens, and patient monitors to interact with technology. Due to the fact that technology includes information that many would prefer to keep private, people believe that health information technology can be risky; nonetheless, safe patient care relies on information and technology skills. Healthcare providers now have access to streamlined patient information. The benefits of medical information technology include the ease to retrieve health information, the ability to speedily communicate patient information, and the decreased risk of medication errors. Healthcare technology platforms now include algorithms and wearable devices to help patients make updated decisions to improve their health. As learning algorithms interact with training data, they become more precise and accurate (which allows humans to achieve insight into treatment variability, diagnostics, and patient outcomes). Healthcare ICTs with computerized medical record systems (EMRs) offer the advantage of cheaper and more efficient solutions to illnesses. EMRs synchronize care and distribute information to other clinicians. Doctors and nurses use portable devices, record real-time data, and instantaneously update medical charts; many hospitals and healthcare facilities use tablets to write prescriptions and order tests. Patients increasingly prefer mobile devices to track their diets and fitness activities. The most recent medical technologies consist of AI and machine learning, telehealth, augmented and virtual reality, cancer immunotherapy, and robotic surgery. Promising technologies include chatbots, voice search, and blockchain. 

Holistic health’s ancient principles offer sustainability because holistic alternative and integrative approaches support a whole person. Holistic nurses focus on treating patients as whole beings instead of specific symptoms. They frequently promote self-responsibility, self-reflection, self-care, and spirituality to help their patients maintain a healthy balance of body, mind, and spirit. As the nursing profession requires the core of what makes us human (such as being empathetic and caring) patients can benefit from frequent communication with their nurses, access to high-quality health information, and prevention strategies. Emerging technologies in telehealth can also help to alleviate the burden on nurses (it requires fewer nurses to provide adequate care). Simplified data collection, analysis, efficient charting, staff scheduling, ordering of medications, increased patient safety, improved health care facilities, and research rely on the use of EMRs. Nurses are uniquely positioned to become leaders in the use of ICTs; it presents them with real-time access to patient information, promotes the nursing management outcome, and provides the opportunity to reach geographical areas that have health professional shortages. 

Neuroscience requires high-quality functional brain imaging (FBI) to understand and monitor the progression of diseases. Diffuse optical tomography (DOT), developed at the University College of London, England, offers radiation-free, non-invasive methods. The strong, magnetic field of functional magnetic resonance imaging (fMRI) is unstable for people with implanted active electronic devices such as cochlear implants, deep brain stimulators, and pacemakers. Optical technologies have a relatively high tolerance for external electromagnetic interference. Although diffuse optical imaging (DOI) is one of the most sophisticated optical imaging methods to observe anatomical and functional information, it provides insight into neurological and psychiatric disorders such as autism spectrum disorders, Alzheimer’s disease, and cerebrovascular accidents or strokes. DOI uses two-photon microscopy and fluorescence or functional near-infrared spectroscopy (fNIRS). The depth of tissue is important in light absorption; the reconstruction of images relies on a double layer comparison between identifiable values and expected values. Consequently, DOI uses the technique of diffusion equation; boundary element equation (BEM) assumes this double layer with various scattering and absorption coefficients to verify the accuracy of detailed images of molecules, cells, tissues, and organs. An excellent example of the application of this method is the study of neurons to detect lesions in the brain. The BEM technique of photon penetration makes use of high-density DOT to create simulated values for improved image quality and reliability. This reconstruction can be used in medical fields such as oncology, brain imaging, and optical mammography. Although at a considerably reduced resolution, these examples offer a much higher imaging depth. The ability to detect the location of lesions is calculated firstly by the algorithm of image reconstruction and secondly by verifying the accuracy of the algorithm. The design of a proficient algorithm for image reconstruction is of infinite significance. In neurophysiology, cortical computation and equation to improve the accuracy of the image reconstruction algorithm is a challenge for the next decade.
