- High intensity focused ultrasound for tumor therapy(二)This method is simple in the idea and convenient to implement, but because the image accuracy of the B-ultrasound itself is not high, and the information contained the two orthogonal sections itself which is not enough to represent the entire lesion itself, the shape of the tumor is not mostly elliHIFU Piezo information July 09, 2018
- High intensity focused ultrasound for tumor therapy(一)Considering the basic requirements of real-time imaging of tumor treatment ,It includes compatibility considerations and cost control requirements of the ultrasound therapy machine itself, the domestic commercial HIFU piezo ceramic ultrasound tumor treatment machine has selected B-ultrasound as forHIFU Piezo information July 09, 2018
- positioning accuracy of the ultrasonic motorThe equivalent circuit of the complex stator of traveling wave type ultrasonic motor near the resonance frequency is shown . Each parameter of piezoelectric ceramics has the following meaning: the white is the equivalent with static capacitance, which is determined by the dielectric constant of theBasics of Piezoelectric Ceramics July 09, 2018
- The principle of HIFU tumor treatmentThe principle of HIFU piezo ceramic tumor treatment is to concentrate the ultrasound energy into the disease tissue by a certain focusing method.due to the strong energy deposition of the focal point, makes the focal region in a short time (0.5-5s).The target tissue temperature rises above 60C, whicHIFU Piezo information August 15, 2018
- Performance and frequency of ultrasonic transducerWhat’s the common method for measuring the speed of ultrasonic transducers?Among the method about measuring speed of Ultrasonic distance measuring transducer, a resonance method is commonly used, transducers emit similar sound wave of plane wave and then reflected and superimposed by the sound waveUltrasonic Transducer information August 09, 2018
- piezoelectric composite materialIn the 1970s, scientists use piezoelectric ceramic materials(PZT) and non-piezoelectric materials (polymers compound) according to a certain arrangement, thereby forming a combination of piezoelectric materials and non-piezoelectric materials.Piezoelectric composites have their own shortcomings, forBasics of Piezoelectric Ceramics August 08, 2018
