An investigation of the influence of radiographic malpositioning and image processing algorithm selection on ICU/CCU chest radiographsElhain, Ahmed M.S.B. January 2013 (has links)
Mobile chest radiography remains the most appropriate test for critical care
patients with cardiorespiratory changes and with patients who have chest tubes
and lines as a monitoring tool, and to detect complications related to their use.
However, one of the most frequent issues recognized radiographically with
patients in critical care is chest tubes and lines malposition. This can be related to
technical quality reasons which can affect their appearance in the chest
radiography.
This research considers how the technical quality of the ICU/CCU chest radiography
can impact upon the appearance of chest tubes/lines and how that appearance can
impact on the decision making.
Results show that the methods used in the chest phantom experiment to estimate
the degree of angulation have a large effect upon the appearance of anatomical
structures, but it does not have a particularly large effect upon the apparent
changes of tube/line position central venous catheter and endotracheal tube (CVC,
ETT).
The study also shows that there was a little difference between the two image
processing algorithms, apart from the visualisation of sharp reproduction of the
trachea and proximal bronchi, which was significantly better using the standard
algorithm compared to the inverted algorithm.
The two methods used to estimate the degree of angulation and the apparent
position of the CVC/ETT on 17 mobile chest radiographs provide limited useful
information to the image interpreter in estimating the degree of angulation and
degree of malpositioning of the tube and line.
