Abstract: A system and method are provided for generating a predictive model for predicting a postoperative bed type to be used by a patient after surgery. The predictive model is trained on features extracted from medical data and using a postoperative bed type as prediction target in the training. The predictive model is configured to output a probability on a scale 400 which corresponds to, at its lower end, a prediction of a first postoperative bed type and, at its upper end, a prediction of a second postoperative bed. A hybrid model is generated which applies a lower 410 and an upper threshold 420 to the probability scale. If the output probability of the predictive model is in between both thresholds, an expert selection of the bed type is recommended, while otherwise, the prediction of the predictive model is output. The values of the thresholds are optimized using a performance metric.

Abstract: An ultrasound probe (10) is disclosed comprising a plurality of transducer elements (66) within a housing (60) and arranged proximal to a subject contact surface (65) of the probe; a plurality of individually addressable light sources (72) mounted in said housing, each of said individually addressable light sources indicating a position of a subset of the plurality of transducer elements relative to said subject contact surface; and a controller (80) arranged to control said plurality of individually addressable light sources in response to a light source selection signal from an ultrasound user console (3). Also disclosed is such an ultrasound user console (3), an ultrasound imaging system (1) comprising the ultrasound probe (10) and the ultrasound user console (3) as well as a method (100) of marking the location of an anatomical feature (7) within a subject with such an ultrasound imaging system (1).

Abstract: An ultrasound imaging system is for determining stroke volume and/or cardiac output. The imaging system may include a transducer unit for acquiring ultrasound data of a heart of a subject (or an input for receiving the acquired ultrasound data), and a controller. The controller is adapted to implement a two-step procedure, the first step being an initial assessment step, and the second being an imaging step having two possible modes depending upon the outcome of the assessment. In the initial assessment procedure, it is determined whether regurgitant ventricular flow is present. This is performed using Doppler processing techniques applied to an initial ultrasound data set. If regurgitant flow does not exist, stroke volume is determined using segmentation of 3D ultrasound image data to identify and measure the volume of the left or right ventricle at each of end systole and end-diastole, the difference between them giving a measure of stroke volume.

Abstract: Various methods and apparatus disclosed herein relate to apparatus and techniques for harvesting energy from operation of a syringe, and utilizing that energy for various purposes. In various embodiments, a method (400) for harvesting and using electrical energy during operation of a syringe (100, 300) may include: operating (402) the syringe, wherein operating includes displacing a plunger (112) of the syringe to draw fluid into a reservoir (114) of the syringe or expel fluid from the reservoir of the syringe; converting (404), by an electrical generator (120, 122) that is integral with the syringe, motion associated with displacing the plunger into electrical energy; and using (406) at least some of the electrical energy to at least temporarily store, in a memory component (136) integral with the syringe, one or more data points associated with operation of the syringe.
