The CT scanner is a full-featured disease detection instrument, which is referred to as a computerized tomography scan technique. Based on the difference in absorption and transmittance of X-rays from different tissues of the human body, the instrument is used to measure the human body with highly sensitive instruments, and then the measured data is input into the electronic computer. After the data is processed by the electronic computer, it can be photographed. The cross-section or the three-dimensional image of the examined part of the human body was found, and small lesions were found in any part of the body.
Recently, scientists used a CT scanner to take a series of high-resolution 3D photos and recorded the process of growth of the small red dragonfly from centipede to adulthood. The team scanned the little red dragonfly, each 5 mm in length, hanging in a straw and slowly spinning. The CT scan took 200 X-rays and recorded the growth process of the chrysalis and the process of the final destruction of the butterfly.
Scientists pointed out that this study can be used to observe how insecticides affect the development of bees, so they are very valuable for research.
