Radiology. From Analogic to Digital

Digital radiology and PACS.

Future hospital information systems should permit the systematic storage of all information generalized within the hospital, including medical diagnostic images. For such a system to be realized, implementation of a picture archiving and communication system (PACS) is needed. The development of computed radiography with an imaging plate (CR) has made it possible for digitalization of all kinds ...

Digital Options for Panoramic Radiology

signal specific successive approximation analog to digital converter

چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...

Digital Radiology: an Opportunity for Quantitative Measurement

A digital detector provides numerical information at each pixel. This value may be difficult to be interpreted quantitatively. In this paper, the main factors to be considered during physical interpretation are reviewed: beam-hardening effect, scattering diffusion, type of detector. Some of them induce degradation on the digital radiograph while others modify the nature of available information...

Recent Trends in Digital Industrial Radiology

New digital detectors were developed for medical applications, which have the potential to substitute the X-ray film and revolutionise the radiological technique. Flat panels and imaging plates allow a fast detection of radiographs in a shorter time and with higher dynamic than film applications. The properties of these detectors can be controlled by electronics and exposure conditions. New nam...
