The human brain, though one organ in the human system, contains a huge number of detailed networks of neurons running in it. Through years of progress in neuroscience and neuroimaging, we have been drawn closer to an idea about its complex functionality. The more paradigm-shifting techniques in this domain include functional Magnetic Resonance Imaging or fMRI. Beyond these mainstream applications, however, fMRI data have nowadays started to play an important role in developing brain-computer interfaces, which are hard or software systems designed to bridge the gap between human cognition and any external device to which a person would like to be able to control, communicate with, or even interact with in revolutionary ways. What is fMRI? Functional magnetic resonance imaging, or fMRI, is a special type of MRI that measures and maps brain activity by detecting changes in blood flow. When any given part of the brain is more active, it uses more oxygen; hence, more blood flows to it. FMRI

Functional magnetic resonance imaging has changed the existing view of the human brain. Because it is non-invasive, access to neural activity is acquired through blood flow changes. Thus, fMRI provides a window into the neural underpinnings of cognition and behaviour. However, the real power of fMRI is harnessed from sophisticated image analysis techniques that translate data into meaningful insights. A. Preprocessing: Preprocessing in fMRI data analysis is one of the most critical steps that aim at noise and artefact reduction in the data while aligning it in a standard anatomical space. Necessary preprocessing steps include: Motion Correction: The fMRI data are sensitive to the movement of the patient. Realignment belongs to one of those techniques that modify the motion by aligning each volume of the brain to a reference volume. Algorithms used for this purpose include SPM-Statistical Parametric Mapping-or FSL-FMRIB Software Library. Slice Timing Correction: Since the slices of fu

Functional Magnetic Resonance Imaging (fMRI) plays a significant role in diagnosing and treating mental health disorders. This non-invasive imaging technique allows researchers and clinicians to study the brain’s activity and connectivity, providing valuable insights into the underlying mechanisms of various mental health conditions. In this blog, we will delve into the role of fMRI in diagnosing and treating mental health disorders, its benefits, limitations, and future prospects. Diagnosis: fMRI enables researchers and clinicians to observe changes in blood flow and oxygenation levels in different areas of the brain, which are closely associated with neural activity. This information aids in identifying patterns of brain activation that are unique to certain mental health disorders. For instance, fMRI studies have revealed distinct brain activation patterns in individuals with depression, anxiety, schizophrenia, and bipolar disorder. Depression and Anxiety: fMRI can help distinguish

 Within the last couple of years, Magnetic Resonance Imaging (MRI) technology has undergone incredible developments in this particular niche domain of in-bore MRI. These new developments have brought diagnostic accuracy to a higher level and have also greatly improved patient comfort during an MRI scan. Probably the most crucial development in In-bore MRI is increasing the field strengths of operation. Conventionally, an MRI runs on 1.5 Tesla; however, newer technologies have expanded their operations to include 3 Tesla and even 7 Tesla systems. Higher field strengths translate into more detailed and exact images that radiologists can use to focus on tiny abnormalities with accuracy that has not been seen before. This is paramount in neuroimaging and musculoskeletal imaging, where correct visualisation of the case in question is paramount. Multiparametric Imaging: Comprehensive Insights in a Single Scan Another pioneering feature adopted in the state-of-the-art in-bore MRI systems is m

As a healthcare professional, I have always been passionate about innovative solutions for proper patient care. In recent years, a new patient care concept that has gained significant attention is the use of virtual skylights in hospitals. These virtual skylights are an effective way to improve the healing environment and patient experience. In this short read, I will explore the benefits and applications of virtual skylights for healthcare facilities with other design solutions, such as MRI-compatible wheelchairs and monitors. Enhancing the Healing Environment with Virtual Skylights Hospitals using traditional technology often feel sterile and impersonal, negatively impacting patient well-being and recovery. Virtual skylights offer a unique solution by bringing the beauty and serenity of natural light into the hospital setting. These skylights are essentially large LED screens that display real-time images and videos of outdoor scenes, such as blue skies, clouds, and beautiful landsc

Functional Magnetic Resonance Imaging or fMRI, has completely changed the way in which we look at the human brain and see the workings of different parts of the brain in action. Recent developments have significantly raised the resolution, scanning speed as well and sensitivity of fMRI, thus making it a valuable research as well as diagnostic tool. Among the main trends and updates in fMRI, it is necessary to discuss the enhancement of spatial resolution. The current fMRI machines have advanced to be much faster in taking images, hence providing improved and refined images of the working brain. The major factor that has made this leap in resolution has been enhancing hardware, especially the magnetic fields and the gradient coils. Newer techniques of fMRI specify ‘high-resolution’, which allows researchers to include more detailed regions of the brain and associated neural networks, promoting a better understanding of neuroanatomy and functioning. The other key factor that has been en
