Abstract: An ultrasound probe is equipped with a transducer element array and an internally located position marker trackable by a position sensing system or the like. The position marker is supported by a movement and rotation constraining fixture. The fixture is rigidly connected to the transducer element array of the probe. The fixture constrains the position and orientation of the position marker to match a spatial reference relationship with the transducer element array in the position marker's constrained degrees of freedom. The position marker may moved along and rotated in its unconstrained degrees of freedom to match the spatial reference relationship with the transducer element array.

Abstract: Apparatus and methods for measuring and analyzing blood flow in vessels in the bodies of living subjects are provided. The true velocity vector, or a projection thereof onto a scan plane, for blood flowing at a location in a vessel is determined from multiple Doppler velocity components. The true velocity vector is displayed as a directional marker on an image comprising the vessel. The true velocity magnitude and angle, and scalar blood flow characteristics derived therefrom, are plotted as a functions of time and/or position across the depiction of the blood vessel in the image. Time intervals for which blood flow characteristic data is displayed and/or determined may be user configurable.

Abstract: An apparatus and method for generating high quality, high frame rate images in a handheld or hand-carried ultrasonic imaging machine. The apparatus includes an image enhancer to reduce speckle noise and improve the compressibility of the resulting image. This approach reduces the required hardware and power consumption to satisfy the physical space, power, and limited processing power of a handheld probe and enables high quality images to be transmitted efficiently over low-bandwidth connections.

Abstract: An apparatus and method for automatically calculating and applying time gain compensation in a handheld or hand-carried ultrasonic imaging machine. The apparatus include an autogain unit to calculate the time gain compensation based on a processed ultrasound image. The image is divided into regions, and the image intensity is used to mask regions which satisfy a threshold. Masked regions are used to calculate a gain curve which is then spatially and temporally smoothed. Means are providing for masking entire columns of regions to remove areas where the probe is not in contact. This approach may allow less experienced users to achieve high quality images without the difficult and time-consuming task of manually adjusting the time gain compensation.
