摘要:
A compensator is used with a radiation therapy machine to treat a cancer patient. A three-dimensional surface of the compensator is defined by obtaining a radiation dose requirement created by a treatment planning system associated with the radiation therapy machine and determining a plurality of grid elements based on that radiation dose requirement. At least one of a plurality of points on each of the plurality of grid elements is connected with at least one of the plurality of points on another one of the plurality of grid elements to form a representation of the three-dimensional compensator.
摘要:
A method of validating a compensator for use in a radiation therapy machine to treat a cancer patient involves determining a radiation treatment plan based on a compensator description file that includes data representative of an actual machined surface of the compensator. The plan includes operating parameters of the radiation therapy machine, and this plan is compared against actual radiation measurements taken during a non-patient test of the radiation therapy machine with the compensator mounted to the machine. If the comparison results in a match, the compensator is validated for use in the radiation therapy machine to treat the cancer patient.

摘要:
A patient-specific compensator is created from solid particulates on-site at a radiation treatment facility and then used there at that facility in conjunction with a radiation therapy machine to deliver radiation therapy to a cancer patient. After use, the compensator can be broken down into loose solid particulates at the facility, and another compensator can be created on-site at the facility from those particulates and used in the radiation treatment of a different cancer patient at the facility.
摘要:
The invention generally relates to Pro-Drugs of dihydroorotate dehydrogenase (DHODH) inhibitors and methods of use thereof. In certain embodiments, the invention provides a DHODH inhibitor compound including a cleavable functional group that increases bioavailability as compared to a form of the DHODH inhibitor without the functional group, rendering the former more suitable for therapeutic use.
摘要:
The invention generally relates to the preparation and use of consumable products for delivering a bioactive agent to an oral cavity of a mammal. In certain embodiments, the invention provides a consumable product that releases a bioactive agent within an oral cavity of a mammal, the product including a polymer matrix and one or more bioactive agents, in which the matrix is of a heterogeneous thickness.
摘要:
The invention relates to systems and methods for characterizing tissue biopsies, cells and organisms as a result of predictable responses to known compounds. A sensor is used to detect plurality of features indicative of physiological activity in response to the external. A vector quantity comprising a number of dimensions equal to a number of different features is derived from the signal output of said sensor array and compared to one or more reference values to generate a physiological ‘fingerprint’.
摘要:
The invention generally relates to aminopyridines and methods of use thereof. In certain embodiments, the invention provides an aminopyridine or a pharmaceutically-acceptable salt thereof, in which the aminopyridine or the salt thereof includes a cleavable functional group that substantially prevents extra-hepatic hydrolysis.
摘要:
The invention generally relates to compositions including a sodium channel blocker and a B vitamin molecule and methods of use thereof. In certain embodiments, the invention provides compositions that include a sodium channel blocker and a B vitamin molecule. In other embodiments, the invention provides methods for treating a subject having a psychological disorder, a neurological disorder, a neurodengerative disorder, and/or a disorder associated with pain involving administering to the subject a sodium channel blocker and a B vitamin molecule.
摘要:
The method and apparatus are for bending or straightening a material such as a rail. A simple form of the apparatus comprises two spaced contact members for contacting the rail, and a rail lifting member located between these points arranged to lift the rail between the two points, the lifting member being arranged to engage the head of the rail. A preferred method comprises applying a load to the material and, while the load is applied, continuously or periodically measuring the load applied and the displacement of the material relative to the datum, establishing from the measurements a load at which the plastic component of the total deformation measured is equal to the predetermined deformation from the datum, and then removing the load.
