Development of the automatic adjustment system for the appropriate radiopharmaceutical dose

Abstract

Introduction In nuclear medicine examination, it is required to adjust appropriately radiopharmaceutical dose for patient by the patient’s age and physique. Purpose In this study, the system for adjusting an appropriate radiopharmaceutical dose automatically was developed. Materials and methods This system of the developed can calculate appropriate radiopharmaceutical dose based on some guideline of scientific society, and adjust the quantity of solution in syringe by inputting some patient information and the substance of examination. The text data of the information about adjustment are saved on PC after adjusted the quantity of solution. Further the label for pasting on syringe is outputted with a printer. Also the difference between the quantity of solution in syringe filled at dispenser and the calculated volume has been investigated by using various type of radiopharmaceuticals. Results This system consisted of a barcode reader, a PC, a dispenser and a label printer. The size of dispenser is 130 mm × 380 mm × 285 mm, and the weight is 4730 g. The difference between the quantity of solution in syringe filled at dispenser and the calculated volume with PC was 2% or less, and it was shown that it is satisfactory in the practical needs. Conclusion This system adjusts automatically an appropriate radiopharmaceutical dose just inputting some patient information and the substance of examination. This system is efficient of a quality assurance of nuclear medicine examinations. Disclosure We have no disclosure and financial support.
