Abstract: Systems and methods are provided for intraoperative real-time clinical decision support. A system includes a processor, a non-transitory computer readable medium, storing executable instructions, and an output device. An interface is configured to receive a first set of patient data in real-time from at least one sensor monitoring vital signals of a patient during a surgical procedure and a second set of patient data in real-time from an anesthesia machine during the surgical procedure. An input interface receives an indicator representing at least an identity of a therapeutic to be administered to the patient. A machine learning model determines from the indicator, the first set of patient data, and the second set of patient data if an alert should be provided to a user. The output device provides the alert to the user if the machine learning model determines that the alert should be provided.

Abstract: Polymeric sheets suitable for use as solar concentrators in solar thermal devices are provided. Also provided are solar thermal devices incorporating the polymeric sheets. The polymeric sheets have two oppositely facing surfaces. A first pattern is defined in the first surface and a second pattern is defined in the second surface. The first pattern is designed to reduce the reflectance of light incident upon the first surface relative to the first surface in the absence of the first pattern and to channel incident light through the sheet onto the second surface. It does so by redirecting photons incident upon the first surface over a broad range of incident angles into transmittance angles that are more closely aligned with the surface normal of the polymeric sheet. The second pattern is designed to focus the photons transmitted to the second surface of the sheet onto a focal surface, such as a receptacle containing a heat-transfer medium.

Abstract: An ultrasound system comprises a probe for acquiring ultrasound data associated with a patient and a microphone detecting audio. The system further comprises a processor module and a memory. The processor module is configured to receive the ultrasound data from the probe and processes the ultrasound data to form an image file. The processor module is further configured to receive the audio from the microphone and forms a voice recording file based on the received audio. The memory stores the image file and the voice recording file, and the processor module automatically associates the image file and the voice recording file with each other.

Abstract: An ultrasound device determines a position and orientation of a surgical instrument based at least in part on tracking information, such as magnetic field strength, emitted by an emitter of a tracking system and detected by a sensor of the tracking system. The sensor and the emitter are attached to or within a different one of a probe of the ultrasound device and the surgical instrument. The ultrasound device determines an ultrasound imaging parameter, such as an ultrasound beam steering angle, based at least in part on the determined position and orientation of the surgical instrument. The ultrasound device applies the ultrasound imaging parameter to acquire ultrasound image data of a target. The ultrasound device generates an ultrasound image based on the acquired ultrasound image data of the target. The ultrasound image includes a representation of the surgical instrument. The surgical instrument may be a needle.

Abstract: A tracking system that includes a sensor and emitter is calibrated, and a tracked position and orientation of a surgical instrument is determined based at least in part on tracking information emitted by the emitter and detected by the sensor. An ultrasound system performs an ultrasound scan to acquire ultrasound scan data including the surgical instrument. The ultrasound system determines a scanned position and orientation of the surgical instrument based on the ultrasound scan data. The ultrasound system compares the tracked position and orientation with the scanned position and orientation to determine a calibration error. If the calibration error exceeds a threshold, the ultrasound system may (1) prompt a user to repeat the tracking system calibration step, (2) automatically recalibrate the tracking system and/or the ultrasound system, or (3) provide a user option for proceeding with automatic recalibration of the tracking system and/or the ultrasound system.
