In this paper novel compression techniques are developed for portable heart-monitoring equipment that could also form the basis for more intelligent diagnostic systems thanks to the way the compression algorithms depend on signal classification. There are two main categories of compression which are employed for electrocardiogram signals: lossless and lossy. Design of an optimal Wiener filter i...

introduction: good radiographs are required for endodontic therapy and because some patient’s are intolerant to intraoral films and/or sensors, this can cause complications in endodontic treatment. extraoral film placement can be used to obtain clinically diagnostic and working radiographs. materials and methods: the no. 2 receptor was placed against the model ’ s cheek and centered in the mola...

Introduction Marketplace pressures towards "mass customization" are pushing industrial equipment and consumer products to be manufactured in greater numbers of configurations and models. One of the more significant product variety coping strategies to emerge from industry is the increasing emphasis on modularity and reuse of components, assemblies and systems over multiple product generations a...

In this report, we summarize the survey of diagnostic X-ray equipment conducted in 2005, focusing on exposure conditions. What we would like to point out in this report is how prevalent digital image receptor systems have become, including flat panel detectors (FPD), which did not exist in our last survey five years ago. FPD have become popular very quickly among the digital receptor systems us...

Introduction: Medical thoracoscopy is a minimally invasive procedure for diagnosing and treating pleural diseases. Despite its proven role in diagnostic and therapeutic purposes, it is infrequently used, which could be because of cost of equipment and lack of training. We analyzed our initial 3 years record of thoracoscopy at Himalayan Institute of Medical Sciences, a tertiary care center in Hi...

Diagnostic Techniques are increasingly employed by utilities as part of integrated programmes to manage their infrastructure assets. These are sophisticated techniques being applied to complicated and diverse networks of equipment. Consequently there are many concerns that these techniques a) are not sufficiently accurate and b) could aggravate the system by, at the very least, depriving other ...

BACKGROUND Ventilator-associated pneumonia (VAP) can have a clear onset or may be a result of the gradual appearance of symptoms and signs of VAP (gradual VAP). The aim of this paper is to describe the VAP development process with the intention of discriminating between those pneumonias with a clear beginning and those that are diagnosed after a period of maturation. In addition, we evaluate th...

In accordance with a questionnaire survey of diagnostic X-ray equipment enforced in 2005, this report was focused mainly on a photography device. The paper questionnaire was mailed to 667 institutions, and the collection rate was 20.4%. Introductions of digital photographic devices are progressing and flat panel detectors (FPD) are spreading in addition to computed radiography (CR). Examination...

BACKGROUND/AIMS Predicting technical difficulties in laparoscopic cholecystectomy (LC) in a small regional hospital increases efficacy, cost-benefit and safety of the procedure. The aim of the study was to assess whether it is possible to accurately predict a difficult LC (DLC) in a small regional hospital based only on the routine available clinical work-up parameters (patient history, ultraso...
