Automated Fetal Measurement From Three-Dimensional Ultrasound Data
First Claim
1. A method for measuring a fetal parameter from three-dimensional ultrasound data, the method comprising:
- applying a machine-trained classifier to the three-dimensional ultrasound data;
detecting a first fetal anatomy as a function of the applying;
measuring a value of the fetal parameter associated with the first fetal anatomy; and
displaying the value.

Abstract
A fetal parameter or anatomy is measured or detected from three-dimensional ultrasound data. An algorithm is machine-trained to detect fetal anatomy. Any machine training approach may be used. The machine-trained classifier is a joint classifier, such that one anatomy is detected using the ultrasound data and the detected location of another anatomy. The machine-trained classifier uses marginal space such that the location of anatomy is detected sequentially through translation, orientation and scale rather than detecting for all location parameters at once. The machine-trained classifier includes detectors for detecting from the ultrasound data at different resolutions, such as in a pyramid volume.

11. In a computer readable storage medium having stored therein data representing instructions executable by a programmed processor for measuring a fetal parameter from three-dimensional ultrasound data, the storage medium comprising instructions for:
-
receiving user input requesting automatic measurement of a fetal head anatomy, the fetal parameter being for the fetal head anatomy; detecting the fetal head anatomy with a computer learnt classifier, the computer learnt classifier operable to detect from the three-dimensional ultrasound data without user indication of a position; and calculating a value for the fetal parameter. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system for measuring a fetal parameter from three-dimensional ultrasound data, the system comprising:
-
a memory operable to store ultrasound data representing a fetal volume; a processor operable to apply a probabilistic model to detect a first anatomy as a function of the ultrasound data and a position of a second anatomy, the detection of the first anatomy being performed sequentially for at least two of position, orientation and scale; and a display operable to display an image of the first anatomy, a value representing a measurement of the first anatomy or combinations thereof. - View Dependent Claims (19, 20)
