  • Patent number: 10792513
    Abstract: A radiation therapy treatment method includes providing a patient model, dosimetric constraints, delivery motion constraints, and delivery coordinate space of a radiation delivery device, where the delivery coordinate space is represented as a mesh with vertices connected by edges, where the vertices correspond to directions of a beam eye view (BEV) of the radiation delivery device. BEV region connectivity manifolds are constructed from the patient model, the dosimetric constraints, the delivery coordinate space, and existing beam trajectories, wherein each of the BEV region connectivity manifolds represents connections between contiguous 2D target regions. Beam trajectories are selected based on region connectedness information in the BEV region connectivity manifolds, the dosimetric constraints, the delivery motion constraints, and the existing beam trajectories. Radiation is delivered using the radiation delivery device in accordance with the selected beam trajectories.

  • Publication number: 20200171303
    Abstract: A ratio of reversible electroporation and irreversible electroporation may be controlled by selecting a symmetric waveform or asymmetric waveform to either minimize or enhance irreversible effects on cells in the target tissue. Combined reversible and irreversible electroporation includes inserting one or more therapeutic electrodes into a target tissue, introducing an electroporation compound into the target tissue, selecting a pulse waveform that is either 1) asymmetric bipolar that has positive and negative pulses with different durations, or 2) symmetric bipolar that has positive and negative pulses with the same duration, and delivering to the target tissue a series of electrical pulses having the selected pulse waveform.

  • Publication number: 20200171325
    Abstract: A treatment planning prediction method to predict a Dose-Volume Histogram (DVH) or Dose Distribution (DD) for patient data using a machine-learning computer framework is provided with the key inclusion of a Planning Target Volume (PTV) only treatment plan in the framework. A dosimetric parameter is used as an additional parameter to the framework and which is obtained from a prediction of the PTV-only treatment plan. The method outputs a Dose-Volume Histogram and/or a Dose Distribution for the patient including the prediction of the PTV-only treatment plan. The method alleviates the complicated process of quantifying anatomical features and harnesses directly the inherent correlation between the PTV-only plan and the clinical plan in the dose domain. The method provides a more robust and efficient solution to the important DVHs prediction problem in treatment planning and plan quality assurance.

  • Publication number: 20190358345
    Abstract: The present invention discloses amphiphilic nonsteroid anti-inflammatory platinum nanoparticles, preparation methods therefor and applications thereof. The amphiphilic nonsteroid anti-inflammatory platinum nanoparticle includes an amphiphilic complex formed by coordinating a nonsteroid anti-inflammatory drug and a platinum antitumor drug. Compared with other platinum drugs, the amphiphilic nonsteroid anti-inflammatory platinum prepared according to the present invention can self-assemble into a nanoparticle in an aqueous solution without the addition of an additive or a surfactant. The amphiphilic platinum complex can achieve targeted accumulation of tumor tissues by means of the enhanced permeability and retention effect of the tumor tissues, thereby reducing the side effects of platinum drugs.
