A rib surface may be determined based on initially determining a location of a rib shadow region. A first region of interest (ROI) may be automatically selected within an ultrasound image acquired from a lung ultrasound scan of a patient based, at least in part, on a depth of the image. The first ROI may be analyzed to determine at least one rib shadow region. The rib shadow region may be used to automatically select a second ROI. The second ROI may be analyzed to determine a location of a rib surface.

A device for hair removal or treatment of skin comprises a light source, a capacitor for storing charge for delivery to the light source for generating a flash of treatment light and a power source for charging the capacitor. A switching circuit controls the charging of the capacitor from the power source. It has a low side switch and a first unidirectional current flow component in series for carrying a charging current, and a second unidirectional current flow component second of opposite polarity for carrying a discharging current. In this way, the discharging current does not pass through the switch despite having a low side topology.

There is provided an intense pulsed light, IPL, apparatus. The IPL apparatus comprises an IPL light source, a power source, a switch, and a controller. The IPL light source is adapted to generate a pulse of light in response to receiving an electric current. The power source is adapted to provide the electric current to the IPL light source. The switch is electrically connected to the power source and the IPL light source. The controller is configured to provide a pulse modulation signal to the switch to open and close the switch. The switch is adapted to provide pulsed delivery of the electric current to the IPL light source in response to the pulse modulation signal. The controller is configured to control a frequency content of the pulse modulation signal to spread an electromagnetic emission caused by operation of the switch over multiple frequencies.

A power receiver (105) comprises a receiver coil (107) extracting power from an electromagnetic power transfer signal generated by a power transmitter (101). A variable load (511) applies modulation loading to the receiver coil (107). A data transmitter (509) transmits data symbols to the power transmitter (101) by controlling the variable load (511) to load modulate the power transfer signal during communication time intervals that are interspersed by non-communication time intervals during which no data is transmitted to the power transmitter (101). The data transmitter (509) varies the variable load (511) to apply a modulation loading pattern for each data symbol where the modulation loading pattern for each possible data symbol value is different. The data transmitter controls the variable load (511) to apply a repeating loading variation pattern during non-communication time intervals. The repeating loading variation pattern has a power spectral density differing less than 10dB from that of the modulation loading patterns and thus the spectral shapes are closely matching.

A placental imaging system comprises a hand held ultrasound imager for scanning over the lower abdomen of a patient and configured to generate image data. An AI algorithm is used to identify the location and shape of the placenta and cervix within the image data and determine the placenta to internal OS distance. It is thereby determined if the placenta has a positional abnormality, such as if it is low lying or not. A recommendation system receives a gestational age of the patient and the positional abnormality information to recommend a patient action.

The present disclosure provides concepts for analyzing electrocardiogram (ECG) data of a subject. Specifically, a traditional prediction unit is configured to process the ECG data with a rules-based ECG interpretation model to generate first diagnostic labels indicating presence or absence of cardiac conditions. A machine learning prediction unit processes the ECG data with a machine learning-based ECG interpretation model to generate second diagnostic labels indicating presence or absence of cardiac conditions. A mapping unit determines a feature mapping describing first and second diagnostic labels associated with similar cardiac conditions. A combination unit analyzes the first diagnostic labels based on the feature mapping and the second diagnostic labels to generate output diagnostic labels indicating presence or absence of cardiac conditions of the subject. The provided concepts therefore leverage the benefits of both the rules-based ECG interpretation model and the machine learning-based ECG interpretation model to provide output diagnostic labels. Specifically, the granularity of the output of the rules-based ECG interpretation model may be maintained whilst ensuring accuracy via the output of the machine learning-based ECG interpretation model.

Disclosed herein is a method of determining a fat fraction value (130). The method comprises receiving (200) a water Dixon image (122) and a fat Dixon image (124) descriptive of a region of a subject (318). The method further comprises calculating (202) a modified fat fraction map (126) using the water Dixon image and the fat Dixon image, wherein the modified fat fraction map is limited to fat fraction values greater than or equal to zero and preferably less than or equal to one. The method further comprises displaying (204) the modified fat fraction map on a user interface (108) and receiving (206) a selection of a measurement ROI (128) descriptive of an area within the region of the subject from the user interface. The method further comprises calculating (208) the fat fraction value for the measurement ROI using the water Dixon image and the fat Dixon image and providing (210) the fat fraction value. Systems are disclosed, configured to perform the method.
