It is reported that the FDA has approved the two-dimensional shear-wave ultrasound elastography technology of GE and Toshiba Medical some time ago, which means that the ultrasonic shear wave elastography has gradually evolved from a "outstanding" to a new stage of "hundred flowers". The approval of shear wave ultrasound elastography is not smooth. In August 2009, SuperSonic Imagine's ultrasonic shear wave elastography was first approved by the FDA, but only two-dimensional shear-wave ultrasound imaging was approved at that time. (Color velocity imaging), while quantitative measurements are not approved.
Until August 2012, three years later, the FDA approved the shear wave velocity measurement (in m/s), and the Young's modulus measurement was approved in September 2013 (in kPa). In October of the same year, Siemens' Virtual Touch imaging quantification (VTIQ) was approved by the FDA, which broke the unique situation of the sound department. Nowadays, the addition of GE and Toshiba has prospered the ultrasonic shear wave elastography technology, and the ultimate benefit will be the vast majority of patients.
Ultrasound imaging technology is advancing rapidly. Some new imaging technologies and the development of new imaging principles may lead to some industry "black horses". The success of sound science is an example. On the contrary, a Japanese brand has taken the lead in introducing pressure-sensitive elastography technology, but today they are somewhat declining in the era of shear wave elastography. These phenomena are worthy of consideration and reference by manufacturers of national brands.
Cosmetics are compound mixtures made from various raw materials after reasonable blending and processing. There are many types of cosmetics raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: base raw materials and auxiliary raw materials. The former is a main raw material of cosmetics, which occupies a large proportion in cosmetic formulations, and is the main functional substance in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other characteristics to cosmetics. These substances are not used in large amounts in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production processes such as heating, stirring and emulsification.
