Abstract: A hemodynamic monitoring system comprising an ultrasound system comprising a transesophageal ultrasound probe and a computer system coupled to the ultrasound system. The computer system can be configured to calculate an image quality parameter and/or a hemodynamic parameter by segmenting images obtained via the hemodynamic monitoring system to identify a selected anatomical structure therein. The image quality and hemodynamic parameters can be displayed to users, such as medical staff, in connection with the ultrasound images.

Abstract: An apparatus for leveling and smoothing a surface that permits blades to be easily installed and removed from their corresponding trowel arms. The blades are formed such that attachment of a blade to the trowel arm is achieved by simply attaching the blade using one or more threaded bolts. Further, the blades of the subject invention are formed without the need of riveting or welding operations thereby significantly decreasing the manufacturing time and expense of the blades.
