After my induction period, I started on the first stamp project of my own six months later as a junior product manager. Cover image: Internationally At first, it was a huge challenge to switch from purely administrative day-to-day renowned poster artist Claude tasks to working on projects which last almost a year. But over the past few years, Kuhn is happy to have his name I’ve gained a great deal of experience, met some interesting people, discovered on the striking animal-themed many enthralling stories and, of course, organized many wonderful stamp projects, special stamps he designed. such as “50 years Ballenberg” and “Animal friends”. Photo: Thomas Rathgeb During a fascinating tour by the chief architect responsible for looking after the cathe- dral, I explored the history of this ancient building in August 2018 as part of the “1000 years Basel cathedral” project. I can now finally reveal the results in this issue of “Focus on stamps”. My colleagues are also presenting exciting stamps in this issue, and I’m very much looking forward to seeing them all. One of these is the “Hand lettering – calligraphy” stamp. It’s ideal for all those letters, invitations and greetings that I write and send to my loved ones in an attractive envelope with a seal. Another highlight is the stamps on the art of brewing beer. As a woman who prefers regional and special beers to wine, I’m looking forward not just to sampling the beer, but also being able to send it on a stamp in future. The “Animals around the world” set is very uplifting. The exotic animals featured on these stamps are depicted in an extraordinary, bold style. Have you ever seen any of these animals in real life? I hope you do get the opportunity to see them one day – not just on a stamp, but in their natural habitat. I also hope you enjoy discovering the new stamps and would like to thank you for your interest in our magazine.

  • Augmented Reality Magnifying Loupe for Surgery
    E:N:600:656 Computer-Integrated Surgery II Spring 2019 Final Report Augmented Reality Magnifying Loupe for Surgery Mentors : Long Qian Group11 : [email protected] Tianyu Song Dr. Mathias Unberath [email protected] [email protected] Dr. Peter Kazanzides [email protected] May 7, 2019 Abstract A magnifying loupe is often used in surgical procedures such as dentistry. There are three principal reasons for adopting magnifying loupes for operative dentistry: to enhance visu- alization of fine detail, to compensate for the loss of near vision (presbyopia), and to ensure maintenance of correct posture. In previous work, a digital magnification system, was im- plemented on a video see-through head-mounted display (HMD) for surgical applications. In this work, we present an optical see-through HMD (OST-HMD) based augmented reality magnifying loupe system for surgery. We have adapted the Magic Leap One (Magic Leap, Plantation, FL, USA), a light-weight OST-HMD, to provide augmented reality guidance in the optical magnified view. In this report, we present the basic design of the modified HMD, and the method and results of the calibration of Magic Leap One displays to a real-world scene. The final calibration errors are measured both in the magnified view and regular view, respectively. The mean target augmentation error is 3:47 ± 1:03 mm in the magnified view and 2:59 ± 1:29 mm in the regular view. i Contents 1 Introduction1 1.1 Background and Related Work.........................1 1.2 Objectives and Significance..........................2 2 Technical Approach3 2.1 HMD Modification...............................3 2.2 System Calibration...............................4 2.3 AR Rendering..................................6 3 Experimental Results and Evaluation9 3.1 User-Dependent Calibration..........................9 3.1.1 Eye-tracking Based Calibration....................9 3.1.2 Real-to-Virtual Alignment Calibration...............

  • Augmented Reality Magnifying Loupe for Surgery
    Augmented Reality Magnifying Loupe for Surgery Project Proposal Member: Tianyu Song Mentors: Long Qian, Mathias Unberath, Peter Kazanzides Objectives: Design a surgical loupe mount for optical see-through head-mounted display (HMD) and develop a calibration method to associate the field-of-magnified- vision, the HMD screen space and the task workspace. Background and previous works: A magnifying loupe is often used in surgical procedures, including neurosurgery and dentistry. In this project, we focus on dental applications. There are three principal reasons for adopting magnifying loupes for operative dentistry: to enhance visualization of fine detail, to compensate for the loss of near vision (presbyopia), and to ensure maintenance of correct posture. Augmented Reality (AR) has been used in the medical domain for treatment, education, and surgery. Useful information, measurements and assistive overlays can be provided to the clinician on a see-through display. Many dental practitioners use magnifying loupes routinely for clinical work, and dental undergraduates are increasingly wearing them when training, so AR guidance in the loupe can potentially help the practitioner in navigation and operation. In previous work, an augmented reality magnification system, in other words, a virtual loupe, was implemented on a video see-through head-mounted display (HMD) for surgical applications. The system was evaluated by measuring the completion time of a suturing task performed by surgeons. Although it was widely accepted by surgeons as a useful functionality, surgeons were not satisfied with the video quality. Thus, this project uses physical loupes to achieve higher quality optical magnification. Technical Approach Workflow Overview Develop HMD calibration method for Choose single eye approriate Design mount Render AR HMD content with Tool tracking Develop distortion stereo HMD calibration method Figure 1 Technical workflow HMD Choice There are three common Optical See-through HMDs, Microsoft HoloLens, Magic Leap One, and Epson BT-300.

Dental College,Srinagar, India) 5(Junior resident, Govt. Dental College, Srinagar, India) Abstract: Over the past decade, the field of periodontics has seen increasing surgical refinement of many procedures. Consistent successful periodontal treatment procedures demand clinical expertise that challenges the technical skills of periodontists to the limit of and beyond the range of visual acuity. Periodontal microsurgery is the refinement of basic surgical techniques made possible by the improved visual acuity gained with the use of surgical microscope. The effect of periodontal microsurgery may include more predictable therapeutic results, less invasive procedure with reduced patient discomfort, more rapid healing, improved cosmetic results and greater patient acceptance. Keywords: microsurgery, periodontics, surgical microscope, visual acuity. I. Introduction In the minds of many dental professionals, microsurgery is an interesting concept. Periodontal microsurgery is the refinement of basic surgical techniques made possible by the improvement in visual acuity gained with the use of surgical microscope.1 In 1979, Daniel defined microsurgery in broad terms as surgery performed under magnification by the microscope.2 In 1980, microsurgery was described by Serafin as a methodology- a modification and refinement of existing surgical techniques using magnification to improve visualisation, with applications to all specialties.3As a treatment philosphy, microsurgery incorporates three different principles4: 1.

    Review Article DOI: 10.18231/2456-8953.2018.0001 Magnification in Endodontics: A review Meenu G. Singla1,*, Divyam Girdhar2, Usha Tanwar3 1Professor, 2Senior Lecturer, 3MDS Student, Dept. of Conservative Dentistry and Endodontics, Sudha Rustagi College of Dental Sciences and Research, Fariadabad, Pandit Bhagwat Dayal Sharma University, Rohtak, Haryana, India *Corresponding Author: Email: [email protected] Abstract Traditional endodontics has been based on feel not sight. Since the endodontic surgical field is measured in millimeters, endodontic therapy has always been very dependent from the tactile sensation of the operator and its anatomic knowledge. The use of magnification in dentistry appears to be of increasing interest. With the recent advances of magnification devices with increased magnification and illumination there is improved technical accuracy and performance. Now the use of such magnification systems is a very popular practice in dentistry as well. By providing both intense focused light as well as a high degree of magnification, the endoscope, orascope, dental loupes and operating microscope has become an important part of the armamentarium for many endodontics. The aim of this review is to discuss the role of magnifying aids with its added advantages in endodontic. Keywords: Magnification, Dental Loupes, Operating Microscope, Orascope, Endosocope.

  • Dental Magnification Loupes: an Update of the Evidence Mohammad a Aldosari
    REVIEW ARTICLE Dental Magnification Loupes: An Update of the Evidence Mohammad A Aldosari ABSTRACT Aim: To overview dental magnification loupes and to present the updated scientific evidence supporting its use. Background: The practice of dentistry places considerable stress on the operators’ visual acuity and musculoskeletal system. The use of magnification loupes has spanned many decades with claims of supporting visual and postural capacities of dental professionals and enhancing diagnostic and procedural accuracy. Review results: Galilean and prismatic loupes both provide lightweight and clinically appropriate magnifications between 2.5× and 5.0×, with beneficial features such as a fixed working distance and downward lens inclinations. Studies have found significantly increased detection and diagnostic abilities due to enhanced visibility and improved treatment outcomes for some investigated procedures. Postural studies have found improved positioning of the upper body when using loupes as compared to the positioning when using the naked eye, with practitioners experiencing reductions in musculoskeletal symptoms when using magnification loupes. Conclusion: The current evidence supports the presence of some visual advantages of loupe magnification in diagnosis and treatment delivery. However, more clinical trials are needed to investigate different procedure outcomes over the long term. Further, there is robust scientific evidence advocating the use of loupe magnification for postural and musculoskeletal support. Clinical significance: Dentistry is a visually and physically demanding profession with a high prevalence of musculoskeletal disorders among dental professionals. The use of loupe magnification potentially benefits both the dental healthcare provider and patients. Therefore, there is reason to consider the use of loupe magnification as an integral part of dental education and training, as well as a tool in the dental clinician’s armamentarium.
