Automated Three and Four-Dimensional Ultrasound Quantification and Surveillance of Free Fluid in Body Cavities and Intravascular Volume

A system to measure fluid within a body cavity, said system including:

• an interface configured to receive data from an ultrasound transducer;
• an image generator connected to said interface, said image generator configured to generate a three-dimensional sonographic image from the data received from the ultrasound transducer;
• and
• an image processor connected to said image generator, said image processor configured to identify the body cavity in the three-dimensional sonographic image, identify an area of fluid in the body cavity in the three-dimensional sonographic image, and calculate a volume of the area of fluid using the three-dimensional sonographic image and at least one of a stacked crescents process, a spherical fill process, a convex hull process, and a triangulation process.

A non-transitory computer-readable medium having computer-readable instructions stored thereon which when executed by a computer cause the computer to perform a method for measuring fluid within a body cavity, said method comprising:

• receiving data from an ultrasound transducer;
• generating a three-dimensional sonographic image from the data received from the ultrasound transducer;
• identifying the body cavity in the three-dimensional sonographic image;
• identifying an area of fluid in the body cavity in the three-dimensional sonographic image;
• and
• calculating a volume of the area of fluid using the three-dimensional sonographic image with a stacked crescents process, a convex hull process, and/or a triangulation process.
