By A. Stewart Whitley

First released in 1939, this is often the definitive textual content on sufferer positioning for the diagnostic radiography scholar and practitioner. The skilled writer group appreciates that there's no replacement for an exceptional figuring out of simple talents in sufferer positioning and a correct wisdom of anatomy to make sure stable radiographic perform.

This twelfth variation keeps the book’s pre-eminence within the box, with countless numbers of positioning photos and explanatory line diagrams, a basically outlined and easy-to-follow constitution, and foreign applicability.

The booklet provides the necessities of radiographic innovations in a pragmatic approach, warding off pointless technical complexity and making sure that the coed and practitioner can locate speedy the knowledge that they require relating to specific positions. the entire commonplace positioning is incorporated, observed by means of supplementary positions the place proper and illustrations of pathology the place applicable. universal error in positioning also are discussed.

Images can also be reported off site using teleradiology (see p. 27 for summary of components and workflow). Hospital information systems and radiology information systems HIS and RIS contain patient details and examination information. If the digital acquisition system and PACS is connected to a HIS/RIS, then the workflow of a department can be increased by using the RIS data to control workflow, thereby delivering improved patient throughput. For instance, by automatically attaching patient demographic and examination details from the RIS to the image, images can be delivered to the correct destination much faster.

HIS/RIS systems typically use the Health Level 7 (HL7) standard to transfer patient details. 0 is a protocol-based standard to facilitate the transfer of digital images and associated information between devices manufactured by a range of vendors and to aid in the development of PACS. When purchasing a system, a DICOM conformance statement should be received, which will inform how the device and software conform to the standard for its particular function. If a modality does not produce images in DICOM format and it cannot be upgraded to DICOM, then a DICOM secondary capture device will be needed to convert the image to a DICOMconformant image (secondary capture only) and allow the system to be connected to the PACS.

Fluorography employs photographic film to capture the image from the image intensifier. This method has now been largely superseded by digital image-capture methods. 21 1 Digital imaging Introduction Film/screen imaging in radiography is gradually being replaced by digital imaging. There are many advantages to digital imaging; the workflow should be faster, and it allows image processing to optimize the clinical information from an image. Advantages of digital systems Digital imaging exhibits a number of advantages when compared with conventional film/screen imaging: • • • • • • • • • • • • increased latitude and dynamic range; acquisition and display are separate processes; images can be accessed simultaneously at any workstation; viewing stations can be set up in any location; ability to use digital image archives rather than film libraries; images will generally be quicker to retrieve and less likely to be lost; ability to post-process images to aid visualization of anatomy and pathology; availability of soft-copy reporting; no manual handling of cassettes for direct digital radiography (DDR) systems; potential patient dose reduction; potential lower running costs, providing only soft-copy reporting is used; no handling of processing chemicals.
