DOSE VOLUME HISTOGRAM OPTIMIZATION BASED ON QUANTILE REGRESSION
Dose-volume criteria may be equivalently expressed in terms of quantiles. This re-formulation of a dose-volume criteria allows incorporation of dose-volume criteria into a full optimization problem. Radiotherapy treatment techniques are described that may apply optimization-based formulation of quantiles to express dose-volume criterion as an inequality involving an optimization problem, which may improve DVH modeling, improve computational speed and accuracy of radiation treatment planning, and improve the delivery accuracy and efficacy of radiation doses to a patient undergoing radiotherapy treatment.
Systems and methods are disclosed for dynamic adaptation of radiotherapy treatments. Example operations for radiotherapy treatment planning include: obtaining a radiotherapy problem (e.g., a multicriteria optimization problem) for providing radiotherapy treatment; performing treatment planning optimization for delivery of the radiotherapy treatment; and generating treatment plan data based on at least one of a plurality of solutions, with such treatment plan data being used to generate a radiation therapy treatment plan for a particular human subject with a radiotherapy machine. In an example, the treatment plan optimization includes identifying parameterized linear programming equations from the radiotherapy problem; converting the parameterized linear programming equations for execution by parallel processing hardware; and solving a plurality of the converted parameterized linear programming equations in parallel on the parallel processing hardware, to produce the plurality of solutions (e.g., encompassing the pareto surface) to the radiotherapy problem that correspond to the parameters that define the radiotherapy problem.

Systems and methods are disclosed for exploration and adaptation of radiotherapy treatment plans. Example operations for radiotherapy treatment planning include: obtaining a plurality of solutions (e.g., Pareto-optimal solutions) of a radiotherapy problem, exploring the plurality of solutions to identify an additional solution in a submanifold space (e.g., exploration of a Pareto surface), and generating treatment plan parameters based on the additional solution for use in a radiation therapy treatment.

Systems and methods for calculating radiotherapy dose distribution are provided. The systems and methods include operations for receiving data representing at least one of particle trajectories or a dose deposition pattern in a simulated delivery of a radiotherapy plan; applying a dose calculation process to the received data to generate a first radiotherapy dose distribution having a first level of detail; and processing the first radiotherapy dose distribution using a trained machine learning technique to generate a second radiotherapy dose distribution having a second level of detail that enhances the first level of detail.
Embodiments of the present disclosure are directed to treatment planning systems for a radiotherapy apparatus. In one implementation, a treatment planning system may include a computational processor configured to apply a set of instructions to an input data set. The input data set may include a three-dimensional dose distribution for delivery by the radiotherapy apparatus to a volume to be irradiated, a three-dimensional volume image characterizing tissue types within the volume to be irradiated, and a set of apparatus parameters which characterize the radiotherapy apparatus. The set of instructions may include a computational process configured to output a treatment plan for delivery of the dose distribution by the radiotherapy apparatus, by optimising a function representing a time-dependent response of the tissue types to an applied radiation.
Systems for establishing a reproducible breath-holding pattern during radiotherapy are disclosed. An exemplary image-guided radiotherapy system (100) may include an airway breathing controller (ABC) device (160), which may block airflow to the patient during imaging and/or radiotherapy to immobilize a target tumor. A patient may practice breath-holding during a training session until a reproducible breath-hold pattern is established. The patient may perform the breath-hold pattern in imaging and/or radiotherapy sessions, during which physiological signals may be measured from the patient and compared to baseline signals collected during the training session. Variation between measured signals and baseline signals may indicate unreproducible breath-holding, in which case radiation delivery may be altered or halted.

Abstract
Systems for establishing a reproducible breath-holding pattern during radiotherapy are disclosed. An exemplary image-guided radiotherapy system (100) may include an airway breathing controller (ABC) device (160), which may block airflow to the patient during imaging and/or radiotherapy to immobilize a target tumor. A patient may practice breath-holding during a training session until a reproducible breath-hold pattern is established. The patient may perform the breath-hold pattern in imaging and/or radiotherapy sessions, during which physiological signals may be measured from the patient and compared to baseline signals collected during the training session. Variation between measured signals and baseline signals may indicate unreproducible breath-holding, in which case radiation delivery may be altered or halted.
A radiotherapy apparatus includes a rotatable drum on which is mounted a gantry arm carrying a radiation source. The arm extending from the drum to a location of the radiation source is offset from the axis of rotation of the drum and oriented towards the axis. The radiotherapy apparatus further includes a mechanism configured to apply a tilt to the arm at one or more rotational orientations of the drum. The rotatable drum is supported on wheels beneath the drum, and the mechanism is an eccentric mechanism within the wheels and is configured to apply the tilt to the arm via the wheels.
Much of the image processing that is applied to medical images is a form of "inverse problem". This is a class of mathematical problems in which a "forward" model by which a signal is converted into dataset is known, to at least some degree, but where the aim is to reconstruct the signal given the resulting dataset. Thus, an inverse problem is essentially seeking to discover x given knowledge of A(x)+ noise by finding an appropriate reconstruction operator A† such that A†(A(x)+ noise) ≈ x, thereby enabling us to obtain x (or a close approximation) given knowledge of an output dataset consisting of A(x)+noise. Generally, several such processes (or their equivalents) are applied to the image dataset. If the first process (for example, noise reduction) is expressed via a first reconstruction operator A1† characterised by a parameter set Θ1 and the second process (for example, segmentation) is expressed via a second reconstruction operator A2† characterised by a parameter set Θ2, then the result of the two steps applied consecutively is A2†(A1†(y)). This can be expressed as an overall reconstruction operator P+, characterised by a parameter set Φ. If we then allow a machine learning process to optimise P+, then the steps previously carried out separately can be combined into a single optimisation. This yields advantages in terms of computational load and in the accuracy of the end result.

System and method for automatic treatment planning
The present disclosure relates to systems, methods, and computer-readable storage media for radiotherapy. Embodiments of the present disclosure may receive a plurality of training data and determine one or more predictive models based on the training data. The one or more predictive models may be determined based on at least one of a conditional probability density associated with a selected output characteristic given one or more selected input variables or a joint probability density. Embodiments of the present disclosure may also receive patient specific testing data. In addition, embodiments of the present disclosure may predict a probability density associated with a characteristic output based on the one or more predictive models and the patient specific testing data. Moreover, embodiments of the present disclosure may generate a new treatment plan based on the prediction and may use the new treatment plan to validate a previous treatment plan.
The present invention relates to the field of radiation therapy. In particular, the present invention relates to methods for treatment planning for a radiation therapy system. The method includes setting a number of objectives reflecting clinical criteria are set for the regions of interest and generating radiation dose profiles to be delivered to these regions of interest. A convex optimization function for optimizing the delivered radiation based on the objectives is provided and dose profiles for specific treatment configurations including beam shape settings for the radiation dose profiles are calculated using the convex optimization function. Treatment plans including determining the radiation dose profiles to be delivered during treatment based on the treatment configurations are created and an optimal treatment plan that satisfies the clinical criteria is selected.
The disclosed systems and methods for Image-Guided Radiation Therapy (IGRT), utilises an iterative approach which adjusts a treatment plan based on inter- or intra-fraction images to improve the accuracy of the radiation delivered during the overall treatment. The prescribed dose of radiotherapeutic radiation is mapped onto the patient's anatomy using an image acquired of the region, which is to be the target for radiotherapeutic radiation. Following beam-angle-optimisation, fluence optimisation and segmentation, the efficiency of delivery of each segment is determined using an objective function, and the segments ranked according to their efficiency. The plan proceeds with the choice of the most efficient segment (or segments) to be delivered first. When this radiation has been delivered, having been tracked to establish its distribution, this delivered distribution can be subtracted from the original prescribed dose and the process repeated so that the delivered radiation gradually converges on the original prescribed dose.
The present disclosure provides systems, methods, and computer- readable storage media for detecting an anatomical region of interest for radiotherapy planning. Embodiments of the present disclosure may identify (810) a plurality of objects in a medical image and select (820) a subset of the objects by applying a morphology filter (516) to the plurality of objects. The morphology filter may determine a morphological feature associated with each of the plurality of objects and exclude at least one object from the subset when the morphological feature of the at least one object exceeds a predetermined threshold. Embodiments of the present disclosure may also classify (830) the objects in the subset into one of a predetermined set of shapes and detect (840) the anatomical region of interest based on the classified objects in the subset.

G21K 1/04 - Arrangements for handling particles or ionising radiation, e.g. focusing or moderating using diaphragms, collimators using variable diaphragms, shutters, choppers
A radiotherapy apparatus includes a fixed support and a gantry including a chassis part and a source part, the chassis part being rotatably attached to the fixed support to allow rotation thereof about a generally horizontal axis, and the source part being connected to the chassis part via a rotatable connection allowing the source part to rotate relative to the chassis part around a transverse axis. The source part includes a source of therapeutic radiation directed towards the intersection of the transverse axis and the horizontal axis. The chassis part and the source part together define an annular ring that encircles the horizontal axis. In this way, the radiotherapy apparatus can provide the full usual range of treatments, but can also adapt itself to adopt a non-coplanar geometry when required, for example to treat difficult locations in the head and neck.
A fluorescing marker is used in order to mark (for example) a leaf of a multi-leaf collimator and/or the reference points within the field of view. The markers are illuminated with light tuned to cause the markers to fluoresce at a wavelength different to that of the illuminating light. The fluorescence is then detected by a camera. This method allows the image to be captured by the camera with increased contrast. Accordingly, the present invention provides a multi-leaf collimator for a radiotherapeutic apparatus, comprising at least one leaf having a fluorescent marker. The fluorescent marker will usually emit light of a wavelength longer than the incident light, allowing suitable filters to be provided in order to distinguish the light emitted by the markers. A suitable material for use in the fluorescent markers is ruby. The present invention also provides a radiotherapeutic apparatus comprising a multi-leaf collimator as defined above, and a camera arranged to view the fluorescent markers. A source of illumination for the fluorescent markers is ideally monochromatic, or nearly so. The camera can have a filter arranged to substantially prevent light of the wavelength emitted by the source of illumination from entering the camera, thereby improving the contrast of the image. The radiotherapeutic apparatus can also comprise a source of illumination that is optically co-located with a radiation source, to allow the radiation field that will be emitted to be checked visually by an operator. The co-located source is preferably substantially monochromatic, emitting substantially no light at the wavelength of the fluorescent markers. A filter can then be placed over an output of the radiotherapeutic apparatus, for blocking light of the wavelength of the fluorescent markers and thereby enhancing the contrast of the image that is taken of the fluorescent markers.
