“…Physicians make the diagnosis looking at the oculars of the fluorescence microscope. Hence it is necessary to validate somehow the use of digital images in IFA diagnosis, as it has been for radiology in the past [13].…”

In this paper, we report our experience in the development of a system for automatic acquisition of Immuno-Fluorescence Assay (IFA) images. We focus on two basic issues. Firstly, we determine an autofocus function that can deal with photobleaching, a physical phenomenon affecting automatic acquisition of IFA images, and present a set of experiments on real images that confirm its effectiveness. Secondly, we discuss if the physicians may reliably use digital IFA images in place of direct microscope observations to carry out the diagnosis. In this respect, we present the results of a preliminary experiment where physicians perform the diagnosis on a set of images both by looking directly to them at the fluorescence microscope and by looking at digital images on the screen of a workstation.

“…For example, an IP irradiated at an exposure of 1 mR generates an S value of 200 3 . A very high S value reveals a very low dose to the IP per patient 3 . The correlation between the image pixel intensity values and the monitor unit readings was investigated at different sensitivity value being adjusted on the reader.…”

The advancement of digital imaging has prompted more medical institutions to go filmless. The computed radiography (CR) system is becoming an important tool not only in diagnostic imaging, but also in radiation oncology. A new CR system that was specially designed for the use in radiation oncology, Fuji IP cassette type PII has been introduced to the market in the middle of year 2006. This project aimed to study some basic physical characteristics of this new type of cassette and explore its application for performing quality assurance (QA) tests and portal imaging in radiotherapy. All the images were read by FCR 5000 Plus reader. The image was found to reach its saturation value of 1023 (due to the image was stored in 10 bits data) by depending on the sensitivity value being adjusted. The uniformity test gave the result of 0.12%. The cassette was used to perform the QA tests which were previously performed using film. All the results met the specification as stated in AAPM Task Group 40. The comparison for the portal images of PortalVision contrast-detail phantom showed that the spatial resolution of the images obtained by CR system (Fujifilm Co., Ltd., Tokyo, Japan) were better than the EPID (Varian Medical Systems, Inc., Palo Alto, USA) and film system (Eastman Kodak Co., New York, USA). The IP cassette type PII was found to be suitable as an alternative QA test tool and portal imaging in radiotherapy.

“…The potential capability of radiology information systems (RIS) and picture archiving and communication systems (PACS) is well documented [7][8][9][10][11][12][13][14][15]. The integration of these systems with the electronic patient record (EPR) in addition facilitates the access to and utilization of images and radiology reports.…”

Do clinicians read our reports? Integrating the radiology information system with the electronic patient record: experiences from the first 2 years

This study aimed to determine how clinicians adapted to and utilized new routines for accessing radiology reports after the integration of an electronic patient record (EPR) with a radiology information system (RIS). Activity-related data describing the availability and receipt of radiology reports were collected from the EPR and the RIS over a period of 2 years. Twelve percent of the final radiology reports had not been opened 4 weeks after they had been entered into the EPR. For opened reports, the median time after a report was available in the EPR until it was first opened by a clinician was less than 1 h for preliminary reports and less than 4 h for final radiology reports. The use of radiology reports was stable during the second observation year. Some reports were not opened for professional as well as technical reasons. The integrated information systems offered a potential for improving routines related to the transmission of radiology reports. Clinicians did not fully take advantage of this potential in the 2 years after its introduction.
