Problems solved by technology

[0010] However, the above process tends to be time consuming, may involve user intervention or trained ultrasound recording personnel, may be subject to operator variability, or may be prone to false detections
Access to trained ultrasound recorders or ultrasound technicians is particularly difficult in remote or rural markets, making remote areas underserved or underserved

Embodiment Construction

[0021] According to an embodiment of the present invention, an ultrasound system is provided for automatically detecting and measuring one of a femur and a skull of a fetus, and thereby automatically estimating the gestational age of the fetus.

[0022] According to an embodiment of the present invention, figure 1 An ultrasound system 10 is shown that includes a transmitter 12 that drives an array of elements 14 (ie, sensor elements) in an ultrasound transducer 16 to transmit pulsed ultrasound signals into a body or imaging volume. The element 14 can be arranged, for example, in one or two dimensions. Each ultrasonic sensor 16 has a defined center operating frequency and bandwidth. Ultrasound signals are backscattered from structures within the body, like fat or muscle tissue, to generate echoes that return to element 14 . The echoes are received by receiver 18 and passed through beamforming electronics 20 to acquire image data from the raw sound data received by ultrasonic ...

Abstract

The present invention relates to a system and a method of automated gestational age assessment of fetus. An ultrasound system includes a transducer array comprising a multiplicity of transducer elements configured to acquire image data of an object, a display system for displaying an image of the object based on the acquired image data, and an image processor module. The image processor module is programmed to calculate the curvature of the image, and identify an object feature based on the calculated curvature and based on known feature tendencies of the object.

Description

technical field [0001] Embodiments of the present invention relate generally to ultrasound imaging, and more particularly, to apparatus and methods for automatically assessing human gestational age. Background technique [0002] It is well known that in ultrasound imaging a series of high frequency sound pulses are generated and that these pulses "bounce" or reflect back from various objects along their path. Specifically, different structures in a patient's body exhibit different levels of impedance, and ultrasound echoes are generated when ultrasound signals touch the impedance boundaries between these structures. The interval between the transmitted pulse and the reception of the corresponding echo is measured to determine the distance between the source of the pulse and the impedance boundary from which the echo originates. In addition, the relative intensity of the echo carries information about the nature of the tissue causing the echo. Different tissues exhibit diff...
