  • Patent number: 11167083
    Abstract: The present disclosure relates to systems and methods for controlling an MRI safe patient care/monitoring system. The system may include a an MRI safe infusion pump that contains a co-processor which acts as a central brain for all other patient care/monitoring devices in the MRI room. The co-processor is separated from the primary processor by a buffer in the infusion pump's memory, so that no actions by the co-processor can affect the primary processor. The co-processor controls the display software, alert software and alerts database. All other patient care/monitoring devices are connected to the MRI safe infusion pump in a daisy chain, so that they can share a single connection to outside the MRI room. Outside the MRI room the co-processor has access to the remote control & display, which contains the remote control GUI, and to the internet, through which it will access an external medical network, which contains an algorithm database.

    Abstract: A method and a system are provided for automatically delineating a striatum in a nuclear medicine brain image and calculating a striatum specific uptake ratio. In the method, initially, a target image is obtained. Then, the target image is projected to a space coordinate to generate a projection amount; an upper end and a lower end of a brain are obtained; and a preset range from the upper to the lower ends is set as a striatum slice area in the target image. A brain area is determined from the target image by a line detection method. Then, a brain volume template is deformed according to the brain area and the striatum slice area, so that a striatum in the brain volume template corresponds to the target image to delineate a striatum region of the target image. Finally, a specific uptake ratio of the striatum region can be calculated.

  • Patent number: 11076916
    Abstract: A thermal accelerant is delivered to a tissue site and localized to modulate the shape, extent or other characteristic of RF or microwave-induced hyperthermia tissue ablation. The accelerant may be provided via an image-guided hand piece or via a lumen added to a microwave antenna, and promotes faster heating, more complete ablation and/or a more extensive treatment region to reduce recurrence of treated cancers, overcoming natural limitations, variations in tissue response and drop-off or thermal loss away from the antenna. The accelerant is delivered as a viscous but heat sensitive fluid, and is fixed in place to provide regions of preferential absorption or heating. Shorter exposure times to heat the far field may allow survival of vulnerable tissue such as vessels, and multiple antennae may be used for effective treatment of irregular or large tumors.

  • Patent number: 11000262
    Abstract: An ultrasonic diagnostic imaging system produces contrast enhanced images which are processed differently during different stages of contrast agent wash-in. During an initial stage of contrast wash-in, imaging is done using pixels processed by maximum intensity detection, to better reflect the rapid change in contrast intensity. During a later stage of contrast wash-in, time averaged processing is used to diminish the effects of noise and motion on the pixel values. During an intermediate period of peak enhancement, a combination of both pixel values processed by both techniques is used. In another aspect, a wash-in period can be characterized by an appearance stage, a growth stage and a peak stage, in which contrast pixel data is adaptively processed in different ways during these periods.

  • Patent number: 10813699
    Abstract: A medical image-processing apparatus according to embodiments includes processing circuitry. The processing circuitry acquires volume data in which a blood vessel including a plurality of branch vessels leading to a plurality of target areas, respectively, is imaged. The processing circuitry extracts a blood vessel structure of the blood vessel included in the volume data. The processing circuitry sets a plurality of the target areas in the volume data. The processing circuitry acquires a plurality of delivery points that are points at which a drug is given to the target areas from a catheter moved inside the blood vessel based on the blood vessel structure of the blood vessel and a positional relationship between the respective target areas and the respective branch vessels in the volume data. The processing circuitry outputs the delivery points.

  • Patent number: 10806808
    Abstract: The present disclosure describes a non-linear compartmental model using PET-derived data to predict, on a patient-specific basis, the optimal therapeutic dose of cargo carrying antibody (e.g., huA33) such as radiolabeled antibody, the antigen occupancy, residency times in normal and malignant tissues, and the cancer-to-normal tissue (e.g., colorectal cancer-to-normal colon tissue) therapeutic index. In addition, the non-linear compartmental model can be readily applied to the development of strategies such as multi-step targeting (MST) designed to further improve the therapeutic indices of RIT.

  • Patent number: 10796463
    Abstract: Disclosed aspects relate to the acquisition and processing of projection data using temporal characteristics of the imaged volume, such as the uptake and clearance of a contrast agent within the volume. Such temporal aspects may be used in the acquisition process, such as to differentially acquire images based on the propagation of the contrast agent. In addition, such temporal aspects may be used in the processing of projection data to generate differential projections (e.g., first or second order subtraction projections), compound projections synthesized using the absolute or relative maximum opacity values observed over time for a region of interest, or interpolated projections synthesized using observed opacity values at known or fixed time intervals and a derived peak opacity time.

  • Patent number: 10779786
    Abstract: A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains image data rendering a blood vessel of patient. The processing circuitry performs a fluid analysis on the obtained image data and calculates an index value related to a blood flow in the blood vessel with respect to each of a plurality of positions in the blood vessel. With respect to the index values to be calculated, the processing circuitry selects a position in which a first value is to be obtained from among the plurality of positions or selects a value serving as the first value from among the index values exhibited in positions. The processing circuitry causes a display to display the first value in a predetermined display region thereof used for displaying the first value.
