Problems solved by technology

However, due to the special nature of I131 radioactivity, if it is discharged without restriction, it will inevitably cause malignant consequences similar to the loss of control of radioactive sources, causing panic in the crowd; therefore, the country has clear regulations on the discharge standard after taking I131, that is, no more than 10mci
[0003] General hospital discharge standards use hand-held radiation detectors to measure and then quantify the activity in the human body. However, due to objective reasons such as distance or uneven distribution of drugs in the human body, the measurement is inaccurate, which may result in higher discharge than this standard.
Most hospitals use ECT scanning for I131 imaging, but the cost of scanning is too high, and it also causes waste of resources

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a nuclide distribution imaging device. Background technique [0002] Due to environmental pollution and excessive life pressure, more and more people suffer from thyroid diseases. As a precise targeted drug, oral I131 for the treatment of hyperthyroidism or thyroid cancer has been accepted by more and more patients. However, due to the particularity of I131’s radioactivity, if it is discharged without restriction, it will inevitably cause malignant consequences similar to the out-of-control of radioactive sources, causing mass panic; therefore, the country has clear regulations on the discharge standard after taking I131, that is, it should not exceed 10mci. [0003] General hospital discharge standards use hand-held radiation detectors to measure and then quantify the activity in the human body. However, due to objective reasons such as distance or uneven distribution of drugs ...
