Real-Time Superficial Vein Imaging System for Observing Abnormalities on Vascular Structures

Circulatory system abnormalities might be an indicator of diseases or tissue damage. Early detection of vascular abnormalities might have an important role during treatment and also raise the patient's awarenes. Current detection methods for vascular imaging are high-cost, invasive, and mostly radiation-based. In this study, a low-cost and portable microcomputer-based tool has been developed as a near-infrared (NIR) superficial vascular imaging device. The device uses NIR light-emitting diode (LED) light at 850 nm along with other electronic and optical components. It operates as a non-contact and safe infrared (IR) imaging method in real-time. Image and video analysis are carried out using OpenCV (Open-Source Computer Vision), a library of programming functions mainly used in computer vision. Various tests were carried out to optimize the imaging system and set up a suitable external environment. To test the performance of the device, the images taken from three diabetic volunteers, who are expected to have abnormalities in the vascular structure due to the possibility of deformation caused by high glucose levels in the blood, were compared with the images taken from two non-diabetic volunteers. As a result, tortuosity was observed successfully in the superficial vascular structures, where the results need to be interpreted by the medical experts in the field to understand the underlying reasons. Although this study is an engineering study and does not have an intention to diagnose any diseases, the developed system here might assist healthcare personnel in early diagnosis and treatment follow-up for vascular structures and may enable further opportunities

NEAR INFRARED IMAGING FOR SUBCUTANEOUS VEINS LOCALIZATION USING WEARABLE OPTICAL IMAGING DEVICE

Intravenous (IV) catheterization is a basic need for medical treatment. Skilled trained medical practices such as doctor, nurse or even paramedic need to learn as this their basic knowledge. To perform this treatment, they need to locate veins they can get by visual or feel it with their fingers. This technique has its own downside as sometimes different patient have differ skin tone and deepness of their veins. Sometimes patients also get scars or even some of them have thick hair. To attempt venipuncture, sometimes they need to repeat it two or three times if it does not succeed. This is due to non-visibility to locate patient’s veins. This may result severe pain to the patient and leave a bigger impact to their health. These inaccurate catheter insertions need to be overcome with a device that can help medical practitioners to locate veins from patients easily and fast for venipuncture process. Today’s technology give human to look through human’s body but non of them have a capability to locate and display subcutaneous veins structure right in front of their eyes for a user to perform iv catheterization process. In this project, near infrared (NIR) imaging technique will be choose as it has several advantages in compared to the other techniqu

Close Encounters of Three Kinds: On Teaching Dominance Feminism and Intersectionality

I am pleased to be a part of this symposium honoring Catharine MacKinnon\u27s groundbreaking work as a feminist theorist, legal advocate, and global activist. This invitation not only presents the opportunity to examine the interface between dominance theory and intersectionality, but also the occasion to delve further into the vexed rhetorical politics surrounding feminism and antiracism. By now the fact that there has been a contested relationship between antiracism and feminism is almost axiomatic.1 Yet as with most things that have become matters of common knowledge, there is a risk that generalizations can metastasize into hardened conclusions that obscure rather than illuminate important dynamics among people, theories, and movements

Interior Materiality

The knowledge of materials and finishes is the bridge that links conceptual design to real-world application. It is among the core content of virtually all interior architecture/design curricula, moreover, access to up-to-date information on emerging technologies and trends is a key exigency for the contemporary designer. Accordingly, this book is authored to form a comprehensive resource for the “hows” and “whys” surrounding the functional and aesthetic contributions of a wide selection of materials and finishes used in multiple spatial design contexts. The knowledge base presented here is not only useful in shaping spatial experience, ensuring occupant well-being, and employing sustainable thinking but also beneficial in managing budget and schedule while enabling the delivery of top-quality work. The book investigates fundamental material properties, performance criteria, as well as sector-specific standards, regulations, and guidelines, with a special focus on concerns surrounding occupant health and safety as well as environmental impact and sustainability concerns. Furthermore, fabrication, installation, and maintenance issues were explored in detail. Various information collection and organization conventions are also discussed with regard to detailing, specification, estimation, and documentation of materials and finishes. The goals of the book can be listed as follows: ● Developing a vocabulary and knowledge base to comprehend and communicate concepts and paradigms associated with the history, classification, manufacturing, evaluation, fabrication, installation, and maintenance of materials and finishes. ● Identifying a broad range of materials and finishes, considering their aesthetic and performance properties, and understanding their utilization with regard to creative design intent, client expectations and requirements, user needs and experience, and incorporating life cycle implications. ● Providing a basis for achieving physical and psychological well-being for occupants, understanding the impact of changing social, cultural, economic, and ecological context, and eliminating negative environmental and social outcomes.https://newprairiepress.org/ebooks/1042/thumbnail.jp
