  • Patent number: 11883230
    Abstract: A transcranial scanning device and method of use is disclosed. The transcranial scanning device is for identifying a neurologic-injury-mechanism and comprises a sensing wand comprising a transducer that produces and receives sound waves. The sensing wand is passed over a head of a patent with cerebral malaria, and sound waves reflect off of blood cells in blood vessels in the head of the patient creating an output sound wave responsive to a blood flow of the patient. The output sound wave is received by the transducer. An output screen coupled to the sensing wand, displays in real time an output waveform corresponding to the output sound wave, wherein the output waveform is indicative of one or more symptoms of cerebral malaria, and wherein said symptoms identify one or more neurologic-injury-mechanism occurring within the patient.

  • Patent number: 11883231
    Abstract: A system for generating ultrasound data in respect of an anatomical body being scanned makes use of a predetermined scan protocol, which specifies a sequence of types of ultrasound scan of structures of interest. These types may for example be different imaging modalities (static, dynamic, 2D, 3D etc.) which are most appropriate for viewing different structures within the anatomical body. From received ultrasound images, a model is used to identify the structures of interest within the ultrasound images. The best images for creating the types of scan of the protocol are then identified and a sequence is compiled of those best images. In this way, a sequence is created which combines different types of scan, in a structured way according to a predetermined protocol. This makes the analysis of the sequence most intuitive for a user, and simplifies comparison between different sequences.

  • Patent number: 11883688
    Abstract: Systems and methods for non-invasive fat reduction can include targeting a region of interest below a surface of skin, which contains fat and delivering ultrasound energy to the region of interest. The ultrasound energy generates a thermal lesion with said ultrasound energy on a fat cell. The lesion can create an opening in the surface of the fat cell, which allows the draining of a fluid out of the fat cell and through the opening. In addition, by applying ultrasound energy to fat cells to increase the temperature to between 43 degrees and 49 degrees, cell apoptosis can be realized, thereby resulting in reduction of fat.

  • Patent number: 11878186
    Abstract: The accuracy charged-particle beam trajectories used for radiation therapy in patients is improved by providing feedback on the beam location within a patient's body or a quality assurance phantom. Particle beams impinge on a patient or phantom in an arrangement designed to deliver radiation dose to a tumor, while avoiding as much normal tissue as can be achieved. By placing fiducial markers in the tumor or phantom that contain specific atomic constituents, a detection signal consisting of atomic fluorescence is produced by the particle beam. An algorithm can combine the detected fluorescence signal with the known location of the fiducial markers to determine the location of the particle beam in the patient or phantom.

  • Patent number: 11850100
    Abstract: A system and computer-implemented method for detecting flow of biological fluid, and facilitating the diagnosis of stenosis or other pathology of a hepatic artery or other non-carotid vasculature by using machine learning to analyze a spectral Doppler ultrasound waveform of blood flow or flow of other biological fluids. A region of interest is identified in a sonogram, a waveform envelope is generated for a waveform within the region of interest, an extracted waveform is generated based on the waveform envelope, a Fourier transform is performed on the extracted waveform, and a Fourier spectrum is generated. Machine learning is used to determine a likelihood of pathology based on waveform parameters, including the Fourier spectrum, and to determine a pathology prediction value. Additional patient information may be accessed and used in determining the likelihood of the pathology.
