US Patent B2, Fetal Heart Rate Monitoring System, Philips
Summary
The USPTO granted Patent US12599356B2 to Koninklijke Philips N.V. for an AI-assisted ultrasound fetal heart rate monitoring system. The system uses a trained object detection model to automatically locate a fetal heart in ultrasound images and switches the probe to Doppler mode for heart rate computation. This patent provides Philips with enforceable property rights for the disclosed technology.
What changed
The USPTO issued Patent US12599356B2 to Koninklijke Philips N.V. covering an ultrasound fetal heart rate monitoring system. The system comprises an ultrasound probe operating in imaging mode to obtain ultrasound images, a trained object detection model applied to locate a fetal heart in a target region addressable by Doppler mode, and automatic switching to Doppler mode when the fetal heart is detected for heart rate computation via Doppler ultrasound signals.
For competitors developing fetal heart rate monitoring or AI-assisted ultrasound systems, this patent establishes intellectual property boundaries. Medical device manufacturers should review the 14 claims to ensure their products do not infringe the disclosed dual-mode ultrasound technology with object detection for fetal monitoring.

Abstract
The invention relates to an ultrasound fetal heart rate monitoring system (100). An ultrasound probe placed on a maternal abdomen provides sensor data. The ultrasound probe is first operated in an imaging mode to obtain an ultrasound image from the ultrasound probe. A trained object detection model is applied to the ultrasound image to determine whether a fetal heart is located in a target region of the ultrasound image addressable by a Doppler mode of the ultrasound probe. If the fetal heart rate is located in the target region, the ultrasound probe is switched to the Doppler mode; a Doppler ultrasound signal is obtained from the ultrasound probe; and the fetal heart rate is computed from the Doppler ultrasound signal.
