  • Patent number: 11064965
    Abstract: A respiratory motion signal generation method operates on emission data (22) of an imaging subject in an imaging field of view (FOV) acquired by a positron emission tomography (PET) or single photon emission computed tomography (SPECT) imaging device (10). An array of regions (32) is defined in the imaging FOV without reference to anatomy of the imaging subject. For each region of the array of regions defined in the imaging FOV, an activity position versus time curve (54) is computed from the emission data acquired by the PET or SPECT imaging device. Frequency-selective filtering of the activity position versus time curves is performed to generate filtered activity position versus time curves. At least one motion signal (66) is generated by combining the filtered activity position versus time curves of at least a selected sub-set of the regions.

  • Patent number: 11034580
    Abstract: The present invention provides stem cells loaded with bi-functional magnetic nanoparticles (nanoparticle-loaded stem cells (NLSC)) that both: a) heat in an alternating magnetic field (AMF); and b) provide MRI contrast enhancement for MR-guided hyperthermia. The nanoparticles in the NLSC are non-toxic, and do not alter stem cell proliferation and differentiation, the nanoparticles do however, become heated in an alternating magnetic field, enabling therapeutic applications for cancer treatment. Due to the fact that circulating stem cells home to tumors and metastasis, and participate in neovascularization of growing tumors, the NLSC of the present invention allows tracking of the tissue distribution of infused stem cells and selective heating of targeted tissues with AMF. NLSC can deliver hyperthermia to hypoxic areas in tumors for sensitization of those areas to subsequent treatment, thus delivering therapy to the most treatment-resistant tumor regions.

  • Patent number: 11033195
    Abstract: A method and system for extracting cardiac cycle parameters from a respiration signal is disclosed. The technique comprises an array of piezoelectric sensors planted on the chest. The chest membrane exhibits the characteristics of bulky attenuator with certain time delay. Contractions and expansions of the heart and lungs muscles model a mechanical load and produce a relative induced strain on the piezoelectric sheet which in turn causes the piezoelectric material to generate a corresponding conformal voltage signal that is mapped with the heart actions. The resultant voltage signal is therefore used to extract and model the corresponding heart parameters utilizing piezoelectric as well as signal processing theories. a direct relationship is established between the output voltage produced by the piezoelectric transducer under hold breathing and the respiration signal collected by the same transducer with respiration.

  • Patent number: 10743941
    Abstract: Methods and systems for performing trackerless image guided soft tissue surgery. For a patient in need of brain surgery, pre-operative preparation for a patient is performed by generating a three-dimensional textured point cloud (TPC) for the patient's scalp surface, and registering the first three-dimensional TPC to a magnetic resonance (MR) model of the brain. During the surgery, an intra-operative cortical surface registration to the MR model is performed for the MR-to-cortical surface alignment. Then shift measurement and compensation to the MR model is performed by: performing absolute deformation measurement of the brain based on the MR model with the cortical surface registration, and obtaining shift correction to the MR model using the absolute deformation measurements. The shift correction may be used for adjusting an image guidance system (IGS) in the brain surgery.

  • Patent number: 10736595
    Abstract: An image control system has a table, a head frame, an imaging system, a rotation system, and a control system. The head frame includes at least one pin which immobilizes a select patient anatomy with respect to the table while the imaging system collects image data through a CT scan process. The CT scan process produces an image of the patient anatomy, with the image including an artifact associated with the at least one pin. The artifact masks an area of interest in the image. The control system determines an angle of rotation which will move the artifact out of the area of interest and rotates at least one of the table, the head frame, and the imaging system by the angle of rotation. A subsequent image produced by the CT scan process includes an image of the patient anatomy with the artifact moved out of the area of interest.

  • Patent number: 10699434
    Abstract: A method is disclosed for determining result data based upon medical measurement data of an examination object. Within the method, a high-dimensional first parameter space is formed, in which measurement values of the various measurements are represented with the aid of value tuples. The measurement values of the various measurements are assigned to a value tuple based on their spatial arrangement in the examination object and/or on their temporal arrangement relative to one another. In the first parameter space, the value tuples are analyzed, using at least one mapping function to at least one further parameter space including a lower dimension than the first parameter space, in order to obtain result data. Furthermore, the result data is output, preferably visualized. In addition, a corresponding device for determining result data is described.

  • Patent number: 10694974
    Abstract: Example embodiments of system and method for magnetic resonance imaging (MRI) techniques for planning, real-time monitoring, control, and post-treatment assessment of high intensity focused ultrasound (HIFU) mechanical fractionation of biological material are disclosed. An adapted form of HIFU, referred to as “boiling histotripsy” (BH), can be used to cause mechanical fractionation of biological material. In contrast to conventional HIFU, which cause pure thermal ablation, BH can generate therapeutic destruction of biological tissue with a degree of control and precision that allows the process to be accurately measured and monitored in real-time as well as the outcome of the treatment can be evaluated using a variety of MRI techniques. Real-time monitoring also allow for real-time control of BH.

  • Patent number: 10687784
    Abstract: A system for insertion of a surgical tool along a trajectory to a target region in a patient's tissues, under the guidance of ultrasound imaging. The system includes a hand-held robot to whose base the probe of an ultrasound system is rigidly connected. The activated platform of the hand held robot carries a surgical tool guide. The alignment of the tool guide defines the trajectory which the tool takes within the subject's body. The position of the target region seen on the ultrasound display, can be recorded, and the robot coordinate frame of reference registered thereto. The system aligns the pose of the robot such that the surgical tool is aimed directly at the target region, independently of motion of the ultrasound probe and its associated robot. An inertial measurement unit can be incorporated to provide back-up positional information if the image of the lesion is lost.

  • Patent number: 10668300
    Abstract: Radiation treatment planning and administration can include a Monte Carlo computer simulation tool to simulate photo-generated electrons in tissue. In the simulation, electrons that have left tissue voxels and entered air voxels can be evaluated to identify electrons that are circling along a spiraling trajectory in the air voxels. After at least one full spiraling circumference or other specified distance has been traversed using a detailed electron transport model, a simpler linear ballistic motion model can be instituted. This speeds simulation while accurately accounting for spiraling electrons that re-enter tissue voxels.
