Background Internet technologies can create advanced and rich web-based apps that allow radiologists to easily access teleradiology systems and remotely view medical images. However, each technology has its own drawbacks. It is difficult to balance the advantages and disadvantages of these internet technologies and identify an optimal solution for the development of medical imaging apps. Objective This study aimed to compare different internet platform technologies for remotely viewing radiological images and analyze their advantages and disadvantages. Methods Oracle Java, Adobe Flash, and HTML5 were each used to develop a comprehensive web-based medical imaging app that connected to a medical image server and provided several required functions for radiological interpretation (eg, navigation, magnification, windowing, and fly-through). Java-, Flash-, and HTML5-based medical imaging apps were tested on different operating systems over a local area network and a wide area network. Three computed tomography colonography data sets and 2 ordinary personal computers were used in the experiment. Results The experimental results demonstrated that Java-, Flash-, and HTML5-based apps had the ability to provide real-time 2D functions. However, for 3D, performances differed between the 3 apps. The Java-based app had the highest frame rate of volume rendering. However, it required the longest time for surface rendering and failed to run surface rendering in macOS. The HTML5-based app had the fastest surface rendering and the highest speed for fly-through without platform dependence. Volume rendering, surface rendering, and fly-through performances of the Flash-based app were significantly worse than those of the other 2 apps. Conclusions Oracle Java, Adobe Flash, and HTML5 have individual strengths in the development of remote access medical imaging apps. However, HTML5 is a promising technology for remote viewing of radiological images and can provide excellent performance without requiring any plug-ins.

Abnormal Anatomy

Non-invasive imaging techniques such as ultrasonography, x-ray, computerized tomography (CT) and magnetic resonance imaging (MRI) provide details about airway anatomy that complement the physical examination. They are of particular value in patients with traumatic injury, malignancy, abscess, foreign body or mass in the airway that displace, distort, disrupt, encroach or compress airway structures in ways that may not be readily apparent otherwise. Many anesthesiologists do not receive formal training in interpreting medical imaging, and a thorough discussion of this subject is beyond the scope of this review. Interpreting the subtleties of normal and abnormal anatomy require years of experience and best left to expert radiologists. The goal here is to introduce the imaging techniques available and examples of clinical applications in airway evaluation of interest to the anesthesiologist. This review contains 12 figures, 2 tables, and 37 references. Keywords: piezoelectric effect, photoelectric interaction, Faraday’s law, pneumothorax, cervical spine injury, LeFort fracture, foreign body, airway infection, mediastinal mass

The aim of this chapter is to highlight the biomedical applications of wavelet transform based soft computational techniques i.e. wavenet and corresponding research efforts in imaging techniques. A brief introduction of wavelet transform, its properties that are vital for biomedical applications touched by various researchers and basics of neural networks has been discussed. The concept of wavelon and wavenet is also discussed in detail. Recent survey of wavelet based neural networks in medical imaging is another facet of this script, which includes biomedical image denoising, image enhancement and functional neuro-imaging, including positron emission tomography and functional MRI.
