Development of a Mini-Mobile Digital Radiography System by Using Wireless Smart Devices

Abstract

The current technologies that trend in digital radiology (DR) are toward systems using portable smart mobile as patient-centered care. We aimed to develop a mini-mobile DR system by using smart devices for wireless connection into medical information systems. We developed a minimobile DR system consisting of an X-ray source and a Complementary Metal-Oxide Semiconductor (CMOS) sensor based on a flat panel detector for small-field diagnostics in patients. It is used instead of the systems that are difficult to perform with a fixed traditional device. We also designed a method for embedded systems in the development of portable DR systems. The external interface used the fast and stable IEEE 802.11n wireless protocol, and we adapted the device for connections with Picture Archiving and Communication System (PACS) and smart devices. The smart device could display images on an external monitor other than the monitor in the DR system. The communication modules, main control board, and external interface supporting smart devices were implemented. Further, a smart viewer based on the external interface was developed to display image files on various smart devices. In addition, the advantage of operators is to reduce radiation dose when using remote smart devices. It is integrated with smart devices that can provide X-ray imaging services anywhere. With this technology, it can permit image observation on a smart device from a remote location by connecting to the external interface. We evaluated the response time of the mini-mobile DR system to compare to mobile PACS. The experimental results show that our system outperforms conventional mobile PACS in this regard.

What’s Past is Prologue: A Scoping Review of Recent Public and Global Health Informatics Literature

“…Specifically, we observed the presence of imaging informatics publications released in 2014 (N=4). These publications described the improvement of imaging services by integrating systems, reducing cost, using mobile devices, applying new imaging techniques in LMICs, and exploring new methods to identify and compare data in images [120][121][122][123][124]. Reviewers also identified an additional theme related to emergency services supported by information systems in LMICs [125][126][127].…”

Development of Patient Status-Based Dynamic Access System for Medical Information Systems

“…Figure 1 shows the environment of the dynamic access control system for medical information. The medical information server consists of the Electronic Medical Record (EMR) system of patients and Picture Archiving and Communication System (PACS), which manages Digital Imaging and Communications in Medicine (DICOM) generated from mobile X-ray imaging devices [20,21]. On the smart terminals and the checking devices of medical personnel for accessing the medical information server, information can be accessed only after receiving authentication via the authentication server that manages the authentication process of medical personnel.…”

Secondary use of hospital information system data for safe bedside radiography in terms of patient factors

“…Radiological technology has been investigated with regard to the reduction of radiation exposure (Ben-Shlomo et al, 2016; Den Harder et al, 2016; Goodman and Amurao, 2012; Iezzi et al, 2012; McCollough, 2012; Sarti et al, 2012; Thabet et al, 2012), the positioning and clarity with which the area under observation is visualised (Hospers et al, 2009; Huang and Schweitzer, 2014; Kijowski et al, 2006; Siddiqui et al, 2014), and the improvement of image quality through advances in devices and systems (Hamer et al, 2005; Inamura and Kim, 2011; Körner et al, 2007; Uffmann et al, 2005; Utsunomiya et al, 2013). Recently, more hospitals have been switching from the use of X-ray film to filmless diagnosis via images displayed on monitors, meaning that images can be rapidly transferred after scanning, and clear images can be accessed on hospital information system (HIS) terminals at any time (Jeong et al, 2014; Utsunomiya et al, 2013). Consequently, even with imaging in the general wards using a portable X-ray machine, it is possible to immediately obtain a digital image of the same quality as one taken in the X-ray room.…”
