Abstract
The growing incidence of skin cancer, with its associated mortality and morbidity, has in recent years led to the developing of new non-invasive technologies, which allow an earlier and more accurate diagnosis. Some of these, such as digital photography, 2D and 3D total-body photography and dermoscopy are now widely used and others, such as reflectance confocal microscopy and optical coherence tomography, are limited to a few academic and referral skin cancer centers because of their cost or the long training period required. Health care professionals involved in the treatment of patients with skin cancer need to know the implications and benefits of new non-invasive technologies for dermatological oncology. In this article we review the characteristics and usability of the main diagnostic imaging methods available today.

Abstract
Knowledge of topographic anatomy is essential prerequisite for any physician to be successful in professional career. That is why we pay special attention to topographic dissections completing course of normal human anatomy at our department. Dissection procedure is subjected to relatively rigid rules demanding removal of some superficial structures during preparation of deeper layers. Thus some important structures get lost for further learning and also for final evaluation of students knowledge and manual skills. Therefore we decided to introduce digital imaging into the recording of course of preparation, the topographic relationships and unique variations. Digital acquisition of pictures through still digital camera makes possible to bypass the wet photographic process and provides instant graphic inputs for further computer processing. The image files can be further edited, printed, archived on various media and then may be used for instructional, test, evaluative, and publication purposes. Moreover, own original pictorial material is feasible to be presented at anatomy lectures. Practical results of this new approach, besides higher attractiveness and motivation impact, allow us to conclude that systematic digital acquisition of dissection pictures combined with computer processing fairly increases quality of anatomical education.

Abstract
BACKGROUND Medical photography is increasingly used by physicians, but studies assessing the perception and acceptability of medical photography by Chinese dermatologic patients are scarce. OBJECTIVE To assess the perception and acceptability of medical photography in Chinese dermatologic patients. MATERIALS AND METHODS From July to December 2014, adult patients visiting the Dermatology Clinic of The First Affiliated Hospital of Third Military Medical University were included in this study. They were required to fill an anonymous questionnaire regarding perception and acceptability of medical photography. RESULTS A total of 509 consecutive patients completed the questionnaire, with 35 and 474 declining and undergoing medical photography, respectively. Meanwhile, 81.0% of the patients preferred to be photographed by attending physicians; 63.3% favored clinic-owned cameras, and 81.0% would rather have their photographs stored in the department's database. Besides, most patients allowed their photographs to be used in case studies (92.8%) or medical record keeping (90.3%). CONCLUSION Most Chinese dermatologic patients accept medical photography. However, the principles of privacy protection and informed consent should be strictly enforced in clinical practice, and appropriate photographic devices and storage methods should be used, for better acceptance.

Abstract
The benefits of digital photography are certainly numerous and include rapid image production, easy and quick deletion of poor images, no need for film or its associated expenses, decreased costs for enlargements, ease of editing and image storage, effortless placement in presentations or publications. Many physicians believe that the benefits of digital images clearly outweigh any limitations that future technologic advances will minimize. Digital imaging allows for the seamless integration of all patient images (e.g., clinical, radiographic, pathologic) into the medical record. Additionally, manipulating these images with lighting, filters, of other processing techniques may encourage diagnostic advances (e.g., distinguishing between benign and malignant surface lesions). Some drawbacks, however, continue to exist, including cost of the hardware and software, continuously evolving technology, power consumption and battery usage, lower image resolution compared with 35-mm photography, and the need to have backup image files. With decreasing costs, improving resolutions, and enhanced capabilities, digital cameras will overcome these limitations rapidly.

Abstract
One of the most significant developments in imaging technology has been the process of digitalization. By incorporating currently available digital imaging equipment into surgical practice, urologists can be assured of obtaining real-time video images with optimal clarity and detail. In addition, one can efficiently capture and store still images that are crisper and sharper than their analog counterparts. These factors greatly improve the diagnostic capabilities and organization of today's endourologist.

Abstract
With the advances in telemedicine and virtual consultation services comes the need for state-of-the-art endoscopic imaging techniques and equipment. Concomitant with current day concerns of cost containment, the ability to utilize the aforementioned tools in a cost-effective fashion that lowers operating expenses, accurately depicts procedures, and expedites chart documentation is paramount. We report on a fast and efficient way to obtain and store images during endoscopic procedures, which can be stored on standard 3.5-inch floppy disks using an innovative digital image recorder. These images are stored as high-resolution (640x480x24) JPEG files, which can be placed in electronic medical records, imported into Internet Web pages, incorporated into slide presentations, and, most importantly, stored in easily accessed archives.

Abstract
BACKGROUND AND OBJECTIVE Digital imaging capabilities have recently been incorporated into a number of video systems. Contrast enhancement when using a rigid or semirigid endoscope improves image definition by seeking out existing transitions in detail. Only the areas of transition are accentuated, whereas areas without detail are unaffected. During flexible endoscopy, fiberoptic bundles create a classic honeycomb appearance. The use of "fiberscope" filters minimizes this appearance by expanding the image of each fiberoptic fiber. We therefore assessed whether new developments in digital video image processing have improved image quality for endoscopic surgery. MATERIALS AND METHODS Fifty urologists reviewed a video playback of various endourologic procedures. The type of endoscope was identified, but the urologic surgeon was blinded to the level of enhancement (high or low) or fiberscope filter (A or B) used. Each video clip was scored from 1 to 5 for the following image variables: identification of structure, detail of image, and background noise or interference. All results were averaged and compared using Student's paired t-test. RESULTS During rigid endoscopy, the high and low digital enhancement settings were both superior to no enhancement (P < 0.001), and high enhancement was better than low (P < 0.001). With semirigid endoscopic procedures, high and low digital enhancement were comparable but were superior to no enhancement (P < 0.001). Filters A and B were no better than no enhancement. There was a significant improvement noted with the use of filter A or B during flexible ureteroscopy over no enhancement (P < 0.001). In addition, filter A was better than filter B (P < 0.001). CONCLUSIONS Digital enhancement settings during video endoscopy significantly improve images from rigid and semirigid endoscopes. The digital fiberscope filter significantly improves images obtained during flexible ureteroscopy. Digital image enhancement capabilities should be strongly considered when upgrading video systems. Digital technology must be further studied to improve clinical video imaging during endoscopic surgery.

Abstract
Digital photographs were taken by a trainee dermatologist of the presenting lesions of 100 unselected, consecutive new patients. For the 38 patients presenting with rashes there was clinical disagreement in only four cases (10%). For the 62 patients with tumours there was clinical disagreement in three cases (3.8%). In a further three cases both clinicians agreed on a differential diagnosis which was subsequently disproved by histological findings and clinical progress. The study demonstrated that an affordable, low-resolution, fixed-focus digital camera with close-up lenses could provide diagnostically useful images suitable for telediagnosis in dermatology.
