Light Skin Interactions

Light and Skin Interactions immerses you in one of the most fascinating application areas of computer graphics: appearance simulation. The book first illuminates the fundamental biophysical processes that affect skin appearance, and reviews seminal related works aimed at applications in life and health sciences. It then examines four exemplary modeling approaches as well as definitive algorithms that can be used to generate realistic images depicting skin appearance. Despite its wide scope of simulation approaches, the book’s content is presented in a concise manner, focusing on relevant practical aspects. What’s more, these approaches can be successfully applied to a wide range of additional materials, such as eye tissue, hair, and water. Allows you to understand and predict the qualitative and quantitative behavior of complex natural systems A general background on tissue optics clarifies several confusing conceptual issues, saving you valuable time in the early stages of research Includes complete code and data sources for the BioSpec model

Light-based therapies have been a major component of dermatologic practice. Historically, these treatment modalities have been mainly tailored to the treatment of patients with light skin. Principles governing use of light therapies in skin of color are less defined. However, there is a tremendous need to understand the benefits and limitations of these therapeutic options for dark-skinned patients as well. Demographic data in the United States alone indicate that the population and recipients of health care are rapidly changing with regard to skin phototype. Physicians who are involved in the delivery of care for patients with cutaneous problems that can be addressed by light treatments need to be able to fully understand the mechanisms, applications, risks, efficacy, adverse events, and other pertinent issues in considering treatment options for their patients with pigmented skin.

It then examines four exemplary modeling approaches as well as definitive algorithms that can be used to generate realistic images depicting skin appearance. An accompanying companion site also includes complete code and data sources for the BioSpec model, which is considered to be the most comprehensive first principles model in the field.

The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

The two-volume set LNCS 10484 and 10485 constitutes the refereed proceedings of the 19th International Conference on Image Analysis and Processing, ICIAP 2017, held in Catania, Italy, in September 2017. The 138 papers presented were carefully reviewed and selected from 229 submissions. The papers cover both classic and the most recent trends in image processing, computer vision, and pattern recognition, addressing both theoretical and applicative aspects. They are organized in the following topical sections: video analysis and understanding; pattern recognition and machine learning; multiview geometry and 3D computer vision; image analysis, detection and recognition; multimedia; biomedical and assistive technology; information forensics and security; imaging for cultural heritage and archaeology; and imaging solutions for improving the quality of life.

The book is structured into eight chapters: 1. Skin anatomy. This chapter is intended to describe the pertinent anatomy related to IPL applications. In addition to the described main structural elements of the skin, the chapter has important points about skin aging and histological aspects which gives the reader a better understanding of the etiology of skin lesions and the need for Intense Pulsed Light (IPL) treatment. 2. Light-tissue interaction. This chapter describes the interaction between IPL and different skin structures. Target skin structures (chromophores) are described in detail. The results of this interaction are detailed as being important to understanding the goals and principles of IPL treatment. 3. IPL safety and legal issues. This chapter describes the needs of the environment for a safe treatment. The necessary equipment and things to avoid pitfalls which may lead to lawsuits are detailed. Several aspects of IPL legal issues are also described: how to avoid medical liabilities and how to manage them are also included in this chapter. 4. Patient selection. This chapter describes the pearls and pitfalls in selecting patients for IPL treatment. This is not an easy task and proper patient selection is extremely important to have satisfied patients. Problematic patient types are also described here. 5. Skin rejuvenation. This chapter starts with a description of skin aging. Intrinsic and extrinsic mechanisms are detailed. The most common skin lesions related to aging that can benefit from IPL treatment for rejuvenation are detailed. The chapter continues with treatment protocols which describe strategies for achieving optimal results. A review of the literature is included, presenting the treatment parameters of different studies and their results. 6. Hair removal. This chapter starts with a description of the hair follicle cycle, hair types and important structures for treatment. Treatment strategies are emphasized and detailed, starting from choosing the right parameters to post-treatment recommendations. A literature review is presented regarding treatment parameters and results according to different authors. 7. Vascular lesions treatment. This chapter describes the types of vascular lesions that can benefit from IPL treatment. The treatment protocol is emphasized and all the steps for performing this application are described in detail. A literature review is presented and different results are compared regarding treatment parameters. 8. Complications. It is inevitable that any medical treatment can end with complications. The possible complications of the most common IPL applications (skin rejuvenation, hair removal, pigmented and vascular lesion treatment) are detailed. The way to avoid them and how to handle them is also described. At the end of each chapter, there is a section on the practical points highlighting the most important points of the chapter. An extensive literature review of this technology is presented alongside numerous illustrations, tables and color pictures. The book will benefit any doctor or healthcare professional who uses IPL for cosmetic purposes, such as plastic surgeons, dermatologists, ophthalmologists, maxillofacial surgeons and otolaryngologists dealing with aesthetics of the face, as well as residents interested in learning the subject.

Dr Henry Lim, renown for expertise and research in photodermatology leads this issue of Dermatologic Clinics. Photodermatology in this issue addresses dermatoses brought on or accelerated by light as well as light forms for dermatology therapies. Photodermatology is used to diagnosis and treat many common conditions that bring patients to the dermatologist. Topics include: Introduction to photobiology; Evaluation of patients with photodermatologic conditions; Photoimmunology; Photoaging; Photocarcinogenesis; Polymorphous Light Eruption (PMLE); Actinic Prurigo; Hydroa vacciniforme and solar urticaria; Chronic actinic dermatitis; drug-induced photosensitivity; Cutaneous porphyrias; Photoaggravated dermatoses; Ultraviolet (UV) based therapy; Photodynamic therapy; Photoprotection. Dr Lim works with one his residents, So Yeon Paek, as his co-Editor on this issue.
