CARE Dose 4D
CARE Dose 4D is an automated exposure control,
which ensures constant diagnostic image quality over
all body regions at the lowest possible dose.
CARE Dose 4D combines three different adaptation
methods to optimize image quality at the lowest dose
level:
• Automatic adaptation of the tube current to the
patient size
• Automatic adaptation of the tube current to the
attenuation of the patient’s long axis, the so-called z-
axis.
• Automatic adaptation of the tube current to the
angular attenuation profile measured online for
each single tube rotation, the so-called angle modu-
lation.
Based on a single a.p. or lateral topogram, CARE Dose
4D determines the adequate mAs level for every sec-
tion of the patient. Based on these levels, CARE Dose
4D modulates the tube current automatically during
each tube rotation according to the patient’s angular
attenuation profile. Thus, the best distribution of dose
along the patient’s long axis and for every viewing
angle can be achieved.
