  • Patent number: 11957505
    Abstract: A system and a method of non-invasive continuous echocardiographic monitoring is provided with an ultrasound transducer and a bedside monitor. The beside monitor includes a monitor central processing unit (CPU). First, the ultrasound transducer is attached onto a specific skin portion of a patient. The specific skin portion is positioned adjacent to a patient's heart. Next, continuous echocardiographic data is sensed with the ultrasound transducer. After relaying the continuous echocardiographic data from the ultrasound transducer to the monitor CPU, the monitor CPU generates a real-time ultrasound image of the heart from the continuous echocardiographic data. Finally, the real-time ultrasound image is outputted with the bedside monitor. If the bedside monitor has a main screen, then the real-time ultrasound image is displayed through a picture-in-picture format with the main screen.

  • Patent number: 11925470
    Abstract: A novel method for using the widely-used electroencephalography (EEG) systems to detect and localize silences in the brain is disclosed. The method detects the absence of electrophysiological signals, or neural silences, using noninvasive scalp electroencephalography (EEG) signals. This method can also be used for reduced activity localization, activity level mapping throughout the brain, as well as mapping activity levels in different frequency bands. By accounting for the contributions of different sources to the power of the recorded signals, and using a hemispheric baseline approach and a convex spectral clustering framework, the method permits rapid detection and localization of regions of silence in the brain using a relatively small amount of EEG data.

  • Patent number: 11903672
    Abstract: Interstitial brachytherapy is a cancer treatment in which radioactive material is placed directly in the target tissue of the affected site using an afterloader. The accuracy of this placement is monitored in real time using a urinary catheter that locates the radioactive material according to the radiation levels measured by sensors in the walls of the urinary catheter. A scintillator that is embedded in the walls of the urinary catheter produces light when irradiated by the radioactive material. This light is proportional to the level of radiation at each location. The light produced by each scintillator is carried through optical fibers and then converted to an electrical signal that is proportional to the light and the radiation level at each location. The radioactive material is located according to the plurality of electrical signals. This location can be used as quality control feedback to the afterloader.
