Nichiyu Giken Kogyo Ltd - Radiation Indicators for Interventional Radiology

Nichiyu Giken is a Japan based R&D company involved in the production of specialized radiation exposure tracking garments equipped with radiation indicators for use in interventional radiology.

Nichiyu produces radiation exposure tracking garments under the RadiMap™ brand. RadiMap™ garments have emerged as a cutting edge tool with radiation indicators for interventional radiology. RadiMap™ offers a significantly enhanced level of safety and reliability in radiology and other healthcare sectors.

These garments help in detecting areas of radiation exposure and deciding the approximate doses during Interventional Radiology (IVR) treatment. This is mainly done through radiation indicators present in the garments.

Nichiyu Giken also produces temperature indicators, ocean exploration equipment, thermite welding powders and moulds, power transmission failure indicators, reinforcement materials for construction work, rocket pyrotechnics and gas generators.

Radimap™ Radiation Exposure Tracking Garments

X-ray irradiation areas in a patient vary with operation conditions based on physical characteristics and IVR operation location, especially in conducing IVR procedures. Even though irradiation of X-rays on different body parts is difficult to assess, the total amount of irradiated X-rays can be measured using special-purpose instruments

During an IVR procedure, chemical indicators associated with RadiMap™ cap and vest show the location where maximum exposure to X-rays has occurred. By referring to reference color charts provided by the manufacturer and comparing color changes, the radiation dosage allowed for a patient in an IVR operation can be calculated.

Features:

• RadiMap™ is offered in two designs: RadiMap vest (VX-B) and RadiMap cap (CX-B)
• The patient's exposure to radiation during an IVR procedure can be gauged by the change in color of indicators
• RadiMap™ does not require X-ray film processing. Exposure is easily visible immediately afterwards
• To facilitate easy handling, radiation-sensitive indicators are directly attached on the RadiMap cap and vest
• The RadiMap cap, vest and radiation-sensitive indicators are not obtrusive. They have no effect on radiology and will not in any way interfere with the IVR procedure
• The operator can estimate the location and approximate radiation dose on the head or the back, since RadiMap garments follow the contour of these body parts
• Change in the intensity of radiation can be noticed with the change in color of the RadiMap indicators from the original yellow, within the X-ray energy range of 70-150kV
