The CARESTREAM DRX-Revolution Mobile X-ray System uses the same
vendor, type, and model antennae originally certified with the Intel 6300
WLAN module and the DLink DAP 2553 Access Point.
When the user obtains an X-ray image, there is generally an optimal alignment
between the radiation source and the two-dimensional receptor that records
the image data. In most cases, the X-ray source provides radiation in a
direction that is perpendicular to the receptor. Use of an anti-scatter grid can
significantly improve the quality of X-ray images. When using a grid, the
requirements for good alignment are much more stringent. For mobile X-ray
systems, the receptor is placed behind the patient and is blocked from the
operator's view by the patient, bedding, and so forth. This makes it very
difficult to align the X-ray source to the detector properly. The grid helps an
operator achieve the correct alignment.
Principle of Operation
The Grid Alignment System uses transmitter emitter coils mounted on the
X-ray source to produce a rotating magnetic field vector.
Magnetic field sense coils are mounted in the perimeter of a frame that holds
the grid and DRX-1 detector. The signal from the emitter is seen by the sense
coils. The processor on the cart interprets the signals to determine the
relative alignment of the X-ray tube and the detector, and displays it on a
graphical user interface.
