| Grid Controlled Fluoroscopy (GCF) is available as an option for use with
all modern Philips RF systems, providing sharper image detail and better contrast than
continuous or conventional pulsed fluoroscopy. Grid control - rather than just grid
switching - controls the output within the X-ray tube itself, eliminating the unnecessary
soft radiation emitted by ramping and trailing components, and allowing the fluoroscopy
parameters to be adjusted within the duration of a single pulse.
All of this is unique to Philips’ GCF. And now, it has become even better:
Dedicated paediatric settings
Dedicated paediatric settings now include a further reduction in dose rate (up to 95%),
with the fluoroscopy parameters precisely adapted to the specific requirements of
paediatric examinations.
GCF Lock In
Parameter control is instant and automatic, but a lock-in feature allows the user to
freeze the parameter settings. This is of particular value during abrupt variations in
absorption, such as the use of lead gloves in the radiation beam.
Adaptive measuring fields
During collimation, the image quality is kept constant automatically, without the need for
manual control. So, especially during arthograms or myelographies the radiologist can
concentrate on the patient instead of the X-ray equipment. |
In-pulse control
Optimum image quality is ensured at all times, because only with GCF it is possible to
adjust kV, mA and ms within the duration of a single pulse. Thus, every pulse produces an
optimized image, with more information to the radiologist.
Minimum dose
The virtually instantaneous response avoids the blooming effect encountered during rapid
movements of the imaging system, while the short, sharply defined pulses eliminate
movement blur. Because of the decrease of exposure the accumulated dose is reduced
drastically.
Visibly better
GCF is more than just an option for your RF system. It is an aid to informed
decision-making, enhanced safety, and efficient patient management in both adult and
paediatric fluoroscopic procedures.
You can make decisions based on fluoro images that visualize exactly what you want. The
use of low-dose frame rates helps to reduce dose, improving patient safety and benefitting
the personnel, who have day-to-day contact with fluoroscopy procedures.
GCF can be supplied as an option with new systems, or as an add-on package for
installed systems. GCF systems can be upgraded as necessary to incorporate new features.
If you have any questions about this exclusive option, don't hesitate to ask your local
Philips representative. |
