The images collected by B-ultrasound diagnostic instrument are digital images, which are processed by digital image processingMedical technology can enhance the definition and clearly process the image of the edge of the lesion. Doctors can make a more accurate and rapid diagnosis by analyzing more clear images, and formulate a scientific and reasonable treatment plan in combination with the actual situation of the patient. The B-ultrasound diagnostic instrument purposely stores the collected images into the computer, establishes the patient related information database, forms a medical image database system, and analyzes the information in the databaseComprehensive management, improve the utilization of B-ultrasound images, and lay a good foundation for clinical diagnosis. The digital storage technology in the B-ultrasound image acquisition system ensures the image access efficiency, improves the B-ultrasound image query speed and management efficiency, and brings convenience to doctors and patients. Digital storage technology also replaces the traditional paper printing media, reduces labor costs and saves expenses. Digital storage can realize the network transmission of data, provide convenient conditions for remote diagnosis, and adapt to the development trend of medical interconnection.
