4.3 Positioning
In-order to achieve a high-quality dental radiograph, follow the processes below:
Positioning the Patient
◆
Place the device parallel to the patient’s mouth.
◆
Make sure the patient ’ s head remains still.
◆
It is recommended to position the DX-7020 about 15~30
˚
from the patient, but the
degree and position can be adjusted according to the user ’ s convenience. However, the
patient should not move while being exposed to radiation.
Positioning the Intra-oral Sensor or Film
◆
X-rays generated by the DX-7020 can be detected by various sensors such as film, intraoral
sensor (digital), and PSP (phosphor plates).
◆
Place film or a sensor behind the teeth and hold it with a finger or positioning device to
keep the film or sensor from not moving.
◆
In the case of using film or PSP, make sure it ’ s not bent or twisted to avoid distortion of
the images.
◆
Sensors should be placed parallel to the center of the focal spot
CHECK
Before the user operates the device, the position of the film, intraoral sensor,
or PSP and DX-7020 should be parallel to each other. If the position deviates,
the image can come out distorted.
