In recent decades, scientists have explored the use of images as an NDT in certain situations, which is more intuitive and convenient than using digital quantities and analog quantities, and can more accurately reflect objective things. The most common methods for the human NDT method are X-ray and ultrasound techniques. The tree B-ultrasound microwave NDT imaging technology has made significant progress internationally from the early 1970s to early childhood. From theory to reality, it has unique characteristics in performance. Currently, the price is still relatively expensive and can be used as other NDTs. Imaging technology supplements. If the new microwave technology, computing technology, and imaging technology are adopted in the future, its advantages of lightness, low cost, high resolution, etc., can be fully utilized and it can replace a large part of other NDT imaging technologies.

The Application of Tree B-type Ultrasonography in Tree Growth Detection
The tree is an anisotropic living natural material that grows. Its defects such as galls, holes, cracks, and frugality can all be attributed to physical, chemical, and biological causes. Because of the climate factors such as water quantity, humidity and temperature, the densities of the molecular structure of the trees will be different, resulting in different sizes of annual rings and the formation of wood grain. The bones, skins, and flesh of various human organs and the bark, branches, trunks, roots, leaves, and knots of trees are all composed of carbohydrates and trace elements. Modern science has also demonstrated that at the molecular level, the chemical structures of chlorophyll and human heme of trees are similar, and they are all quinones complexes. Chlorophyll combines elemental magnesium and heme with elemental iron. Therefore, the similarities between the tree and the human at the molecular level and objectively all are high molecular carbon hydration mesas. With these similarities, the tree's NDT can also be quoted using human NDT methods. The tree B-scanner can detect some of the problems inherent in the tree.
