Abstract

We would like to find out how the artificial insemination of an artificial cardiac pacemaker and defibrillator affects the low-dose chest CT performed for early detection of lung cancer. Using Lungman phantom and artificial heart pacemaker, the control and experimental group were set up to measure the CT value and standard deviation of the man-made objects around the artificial heart pacemaker. Black-hole artifact (black-hole artifact) or pre-speed curing (streak artifact) artifacts were identified around the artificial heartbeater. Depending on the various body types of the examinees and the location of the artificial heart pacemakers, low dose chest CT examinations for early detection of lung cancer are thought to serve as inhibitors to the detection of fine lesions and will require more research to be applied to practical examinations in clinical trials.
