Dose management
DoseWise is a philosophy, a set of principles and practices,
focused on lowering radiation dose for patients and staff.
Philips focuses on system design optimization,
current (mA) optimization and increasing dosage
awareness to reduce the cumulative risk of radiation
while obtaining high-quality images.
DoseRight ACS (Automatic Current Selection)
Optimizes the dose for each patient based on the planned scan by
suggesting the lowest possible mAs settings to maintain constant image
quality at low dose throughout the exam.
DoseRight D-DOM (Dynamic Dose Modulation)
Automatically controls the tube current rotationally, increasing the signal
over areas of higher attenuation (lateral) and decreasing signal over area
of less attenuation (AP).
DoseRight Z-DOM (Longitudinal Dose Modulation)
Automatically controls the tube current, adjusting the signal along the
length of the scan, increasing the signal over regions of higher attenuation
(shoulders, pelvis) and decreasing the signal over regions of less
attenuation (neck, legs).
Dedicated Pediatric Protocols
Developed in collaboration with top children's hospitals, Brilliance age
and weight-based infant and pediatric protocols optimize image quality
with low dose.

RapidView Reconstruction generates up to 20 images
per second using a 512

Cone Beam Reconstruction
Philips patented Cone Beam Reconstruction Algorithm (COBRA)
enables true three-dimensional data acquisition and reconstruction in
spiral scanning.
Adaptive Filtering
Adaptive filters reduce pattern noise (streaks) in non-homogenous
bodies, improving overall image quality.
Adaptive Multicycle Reconstruction
(Part of Rate Responsive CV Toolkit*)
Image data can be prospectively gated or retrospectively tagged.
COBRA automatically delivers the best temporal resolution possible
(as low as 53mseconds).
Evolving Reconstruction
Real-time 256
2
matrix image reconstruction and display in step with
spiral acquisition or off-line. Images can be modified for window width
and level, zoom and pan prior to larger matrix reconstruction. At the
end of the acquisition, all images are updated with the desired viewing
settings.
Off-Line Reconstruction
Off-Line (batch) background image reconstruction of user-defined
groups of raw data files with automatic image storage.
