Patent number: 10076652Abstract: Methods to use medical imaging to monitor the molecule penetration into CNS during ultrasound-mediated delivery are disclosed. The method states a two-step process to predict the amount of molecular penetration which is based on the observation of medical imaging. The first is to propose a unified exposure input to unify the exposure condition so as to build a transferred relation to imaging index. The second is to propose a unified imaging index to unify the imaging readout so as to build a reliable transferred relation to molecular concentration. Linking these two, the molecular penetration induced by ultrasound irradiation can be estimated from medical imaging with ultrasound exposure conditions and molecular sizes.Type: GrantFiled: August 10, 2015Date of Patent: September 18, 2018Assignee: CHANG GUNG UNIVERSITYInventors: Hao-Li Liu, Kuo-Chen Wei, Pin-Yuan Chen, Po-Hung Hsu, Po-Chun Chu, Wen-Yen Chai, Chung-Yin Lin

Patent number: 9743908Abstract: A processing system and a confocal processing method for confocally emitting and receiving ultrasound. Firstly, a first driving electrical signal is generated. Then, at least one first ultrasound signal having a main frequency is emitted to a reflection position according to the first driving electrical signal. With an object at the reflection position, the first ultrasound signal is reflected to form at least one second ultrasound signal. Then, a first analyzed signal whose frequency lower than the main frequency is retrieved from the second ultrasound signal, and other signals are eliminated from the second ultrasound signal, and the first analyzed signal is converted into at least one first analogous signal. Finally, first energy of a first fixed bandwidth of the first analyzed signal is retrieved by the first analogous signal. The method stops generating the first driving electrical signal when the first energy is larger than a predetermined value.Type: GrantFiled: May 28, 2014Date of Patent: August 29, 2017Assignee: CHANG GUNG UNIVERSITYInventors: Hao-Li Liu, Chih-Hung Tsai, Kuo-Chen Wei, Pin-Yuan Chen
