Update on radiating imaging equipment current and future perspectives

This presentation will retrace the history of the technologies using x-rays form the past to current use, recent updates and potential future perspectives. Radiography and computed tomography will be the focus of the presentation. Changes in the most currently used type of radiographic sources in equine practice have been minor since a couple of decades. However, the digital (r)evolution in detectors have introduced major changes and new approaches and uses of digital radiography and new advanced technologies have been introduced in large equine hospitals. Portable sources have changed mainly in size and weight. Fixed sources have improved in maneuverability and displacement in the space and around the horse. Recently robotic technologies, previously used in industry, have been introduced to create new ways of making the sources navigating around the horse and obtaining radiography, fluoroscopy andcomputed tomographic images with volumetric reconstruction. In computed tomography major advances have been made in human medicine equipment and some conceptions of horse dedicated technologies have appeared in equine imaging. Area detectors have changed during last years and speed of acquisition has increased drasticaly. Dual energy and perfusion computed tomography and new algorithms for reducing artefacts have been introduced in recentscanners. Large aperture gantries have been built for human use but serves optimally the use on computed tomography in the horse. in the human field. The advent of sliding gantries has also recently changed the approach of the relative displacement horse/source.
