Abstract: Disclosed is an ultrasonic imaging method. The method includes: on a basis of performing fuzzy segmentation of a membership function on an echo signal, sequentially dividing an input image into a plurality of fuzzy segments according to a strength of an echo; dividing the image into a plurality of layers accordingly; and performing a spatial neighborhood operation on a membership degree value in the plurality of layers, so as to obtain a space fuzzy segmentation array; in another aspect, determining a manipulated variable vector of the image according to image content-based self-adaptive calculation or user-based input, flexibly weighting and stretching space fuzzy segmentation arrays at the layers according to the manipulated variable vector finally, and adjusting and compounding the input image by using obtained echo increment and brightness compensation, so as to obtain a final output image. Also disclosed is a corresponding ultrasonic imaging apparatus.

Abstract: A stable liposomal formulation for ocular delivery of an alpha 2 adrenergic agonist. The formulation contains a liposome that includes a lipid bilayer including a phosphatidylcholine. An alpha 2 adrenergic agonist is encapsulated in the liposome.

Abstract: A stable liposomal formulation for treating cancer. The formulation includes liposomes containing one or more of POPC, DMPC, and DOPC and one or more of the anti-cancer drugs sirolimus, umirolimus, and everolimus encapsulated in the liposomes. Also provided are efficient remote film loading methods for loading the liposomes with the anti-cancer drugs and methods for treating cancer with the liposomal formulations.

Abstract: A stable liposomal formulation for ocular delivery of a carbonic anhydrase inhibitor. The formulation contains (i) a liposome that includes a lipid bilayer formed of a phosphatidylcholine, and (ii) a carbonic anhydrase inhibitor encapsulated in the liposome. Also provided is a method for treating an ocular disorder with the formulation.

Abstract: A 3D ultrasound imaging device including an ultrasound probe assembly and echo analyzer. The ultrasound probe assembly includes a housing and an acoustic window abutted against the housing to form a sealed chamber, wherein the surface of the acoustic window contacts with the breast of the human body to be examined; an ultrasound transducer moves at a first speed back and forth within the sealed chamber and performs high-speed pre-scanning through the acoustic window to obtain initial ultrasound signals; the echo analyzer analyzes the initial ultrasound signals to determine a quality of a ultrasound image acquired by the high speed pre-scanning; and the ultrasound transducer then moves at a second speed to perform another scan to acquire new ultrasound signals. A 3D ultrasound imaging method is also disclosed.
