Problems solved by technology

A large number of practices have shown that the above-mentioned on-site detection or quantitative taking of radioactive drugs is the most cumbersome, and the time of direct contact with radioactive drugs is the longest, and it also contributes the most to the personal dose of radiation workers.

Embodiment Construction

[0041] The system of the present invention includes a processing module 100, a display module 102, a data entry module 101, and a power supply module 103, wherein the data entry module can also be a character recognition entry system module or a two-dimensional code scanning system or an electronic label system 101-1. A batch of radiopharmaceuticals can generally be used for dozens of patients. Because the examination items, body weight, and age of patients are different, the amount of radiopharmaceuticals required is also different. When a batch of radiopharmaceuticals arrives at the Department of Nuclear Medicine, the system can input the activity, detection time, and volume of radiopharmaceuticals given by the manufacturer into the processing module 100 of the system at one time through the data entry module 101, and then apply them to each When there is a patient, you only need to input the current time and the radiopharmaceutical activity value to be used by the correspond...

Abstract

The invention provides a radioactive drug activity real-time measuring / calculating method and system and relates to the technical field of acquiring radioactive drug activity. The system comprises a data entry module, a processing module and a display module. The data entry module is used for entering initial information and current information of a radioactive drug, wherein the initial information of the radioactive drug includes the initial activity, the initial volume and the activity detection time of the radioactive drug and the current information includes current time and the user-needed activity; the processing module is used for calculating the volume of the radioactive drug needed by a user according to the initial information and the current information of the radioactive drug; the display module is used for displaying the volume of the radioactive drug needed by the user. Based on an isotope attenuation law, activity measuring and calculating replaces an on-site activity measuring process; operating personnel can perform one-time extracting according to a calculated drum volume and there is no need to measure the activity repeated on site, so that the radioactive isotope contact time of workers is reduced and the occupational exposure dose of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of obtaining radiopharmaceutical activity, in particular to a method and system for real-time measurement and calculation of radiopharmaceutical activity. Background technique [0002] Radiopharmaceuticals refer to a class of special preparations containing radioisotopes for medical diagnosis and treatment, and are an important part of nuclear medicine. Radiopharmaceuticals are radioactive and unstable, and their instant activity should be evaluated in real time during clinical application. Before the radiopharmaceutical is released from the manufacturer, the radioactive activity is usually measured by the manufacturer, and then the time of activity measurement, activity and drug volume are marked on the accompanying documents or labels. A certain batch of radiopharmaceuticals generally needs to be used for dozens of patient. Since the examination items, body weight, and age of the patient vary, the amount...
