A method and apparatus for treatment planning using four dimensional imaging data.

A compensating device for use in ion-based radiotherapy may comprise a disk with a number of protrusions may be placed in a radiation beam to affect the ions in the beam in different ways to create an irradiation field from a broad beam. This is particularly useful in FLASH therapy because of the limited time available or modulating the beam. A method of designing such a compensating device is proposed, comprising the steps of obtaining characteristics of an actual treatment plan comprising at least one beam, determining at least one parameter characteristic of the desired energy modulation of the actual plan by performing a dose calculation of the initial plan and, based on the at least one parameter, computing a shape for each of the plurality of elongated elements to modulate the dose of the delivery beam to mimic the dose of the initial plan per beam.

A method for processing data relating to a radiological examination of a patient by way of a determining device, comprises the steps of acquiring doses (Ci, ti) measured at a plurality of times ti, storing these time-stamped measurements of radiation doses, and acquiring at least one DICOM digital file containing information on the examination, wherein the method comprises the following steps: acquiring and storing at least one DICOM digital file delivered by the tomograph during or after a tomography; acquiring and storing time-stamped measurements of the doses detected via a scintillating fiber placed on the table, and time-stamped movements of the table; interpolating the measurements (Ci, ti) with data of the image (DICOM) in a common interpolated space and constructing a table (Ck, DICOMk) in the interpolated space; and determining a table of the average dose levels Tz in each slice T depending on the data (DICOMk, Ck).

Systems and methods for treating a lung disease including capturing a first set of images of at least a portion of a lung displaying symptoms of a lung disease, generating a three dimensional model from the first set of images, locating a target nerve proximate the portion of the lung, generating a treatment plan, and non-invasively denervating the target nerve based on the treatment plan such that the function of the portion of the lung is affected.

Residual, refractory or relapsed cancer is treated by immunostimulation in the presence of allogeneic immune effector cells, optimally in combination with radiation therapy. The methods of the disclosure induce a systemic allogeneic anti-tumor immune response that results in tumor regression in untreated sites of disease, i.e. non-injected, non-irradiated, etc.

An interventional therapy system may include at least one catheter configured for insertion within an object of interest (OOI); and at least one controller which configured to: obtain a reference image dataset including a plurality of image slices which form a three-dimensional image of the OOI; define restricted areas (RAs) within the reference image dataset; determine location constraints for the at least one catheter in accordance with at least one of planned catheter intersection points, a peripheral boundary of the OOI and the RAs defined in the reference dataset; determine at least one of a position and an orientation of the distal end of the at least one catheter; and/or determine a planned trajectory for the at least one catheter in accordance with the determined at least one position and orientation for the at least one catheter and the location constraints.

The invention provides methods for treating fibrosis and/or cancer in a subject in need thereof. The methods include providing a composition comprising an inhibitor of IL-4/IL-13 receptor function and administering an effective amount of the composition to the subject to treat fibrosis and/or cancer.

Disclosed herein is a radiation head for a radiotherapy device. The radiation head comprises a source of radiation configured to emit a beam of radiation; and beam shaping device for collimating the beam of radiation. The beam shaping device comprises a multi-leaf collimator; and a diaphragm positioned between the source and the multi-leaf collimator. The diaphragm comprises a diaphragm block movable along a curved path, the diaphragm block having a flat face focused on a focus point which is offset from the source of radiation.

An example method of treating a subject having a tumor is described herein. The method can include determining a radiosensitivity index of the tumor, deriving a subject-specific variable based on the radiosensitivity index, and obtaining a genomic adjusted radiation dose effect value for the tumor. The radiosensitivity index can be assigned from expression levels of signature genes of a cell of the tumor. Additionally, the genomic adjusted radiation dose effect value can be predictive of tumor recurrence in the subject after treatment. The method can also include determining a radiation dose based on the subject-specific variable and the genomic adjusted radiation dose effect value.
