About Low Dose

X-ray units need operating efficiently so that the risk of exposure to X-rays will be minimized and the benefit that patients receive will be maximized.


Radiological protection should basically follow ALARA principle (As Low As Reasonably Achievable: all exposures shall be kept as low as reasonable achievable, economic and social factors being taken into account) of International Commission on Radiological Protection (ICRP), and unnecessary exposure is not recommended.

In particular, since child’s radiosensibility is high as compared with adult’s one, an exposure range needs minimizing. The panoramic exposure of Veraview X800 offers a “child mode” that will narrow the exposure range.

In addition, Morita’s X-ray exposure units have various functions in order to achieve a low dose, including:

  • 180-degree exposure mode in which to achieve a short time and a low dose;

  • FOV (Field of View: exposure region) selectable;

  • Dose Reduction function to lower an irradiated dose to the part that X-rays tend to penetrate;

  • High-speed exposure function (3D Accuitomo F17 series);

  • Function to limit an exposure range ready for cephalometric exposures, and more.

The available functions vary with the model and the specifications. For details, see the pages for each product.

The estimated effective doses of each model are shown on the following site.
