Abstract

Image reconstruction can include using a statistical or machine learning, MAP estimator, or other reconstruction technique to produce a reconstructed image from acquired imaging data. A Conditional Generative Adversarial Network (CGAN) technique can be used to train a Generator, using a Discriminator, to generate posterior distribution sampled images that can be displayed or further processed such as to help provide uncertainty information about a mean reconstruction image. Such uncertainty information can be useful to help understand or even visually modify the mean reconstruction image. Similar techniques can be used in a segmentation use-case, instead of a reconstruction use case. The uncertainty information can also be useful for other post-processing techniques.

Abstract

Techniques for the operation and use of a model that learns the general representation of multimodal images are disclosed. In various examples, methods from representation learning are used to find a common basis for representation of medical images. These include aspects of encoding, fusion, and downstream tasks, with use of the general representation and model. In an example, a method for generating a modality-agnostic model includes receiving imaging data, encoding the imaging data by mapping data to a latent representation, fusing the encoded data to conserve latent variables corresponding to the latent representation, and training a model using the latent representation. In an example, a method for processing imaging data using a trained modality-agnostic model includes receiving imaging data, encoding the data to the defined encoding, processing the encoded data with a trained model, and performing imaging processing operations based on output of the trained model.

Abstract

Image reconstruction can include using a statistical or machine learning, MAP estimator, or other reconstruction technique to produce a reconstructed image from acquired imaging data. A Conditional Generative Adversarial Network (CGAN) technique can be used to train a Generator, using a Discriminator, to generate posterior distribution sampled images that can be displayed or further processed such as to help provide uncertainty information about a mean reconstruction image. Such uncertainty information can be useful to help understand or even visually modify the mean reconstruction image. Similar techniques can be used in a segmentation use-case, instead of a reconstruction use case. The uncertainty information can also be useful for other post-processing techniques.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Efforts have been directed towards faster or more accurate planning processes and more accurate or reliable delivery methods. We propose a treatment planning system for a radiotherapy apparatus comprising a computational processor applying a set of instructions to an input data set, the input data set comprising a three-dimensional dose distribution which is to be achieved by the radiotherapy apparatus within a volume to be irradiated, a three-dimensional volume image characterising the tissue types within the volume to be irradiated, and a set of apparatus parameters which characterise the radiotherapy apparatus, with the set of instructions including a computational process arranged to output a treatment plan apt to deliver the three-dimensional dose distribution when implemented by the radiotherapy apparatus, by optimising a function that includes at least one term representing a time-dependent response of the tissue types to an applied radiation. The set of instructions can then include a fractional distribution step arranged to assign fractional parts of the dose distribution to successive treatment fractions, taking into account time- and dose-dependent characteristics of the tissue types within the volume image, and the iterative computational process can then be arranged, for each non-identical fraction, to take into account the fractional part of the dose distribution and the set of apparatus parameters, to derive a set of treatment instructions apt to deliver the fractional part when carried out by the radiotherapy apparatus. The three-dimensional volume image will ideally characterise the tissue types according to at least their local chemical composition, to assist in modelling the dose response. The optimisation function can include terms representing time-dependent responses such as a cell repair model and a tumour diffusion model.

Abstract

The valve of an active breathing control (ABC) device can be driven by the output of the navigator channel of the MRI scanner, rather than by inference from a measured breath flow rate. Where the MRI scanner is integrated with a radiotherapy device, the MRI data can be used to trigger the enforced breath-hold by the ABC, and the radiotherapy delivered while the ABC valve is shut. If the MRI data pertains to the actual position of the tumor, then the ABC device will (in effect) hold the tumor at a precise and reproducible point for treatment.

Abstract

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.

Abstract

In various embodiments, a system for controlling radiotherapy equipment in a treatment environment includes a controller for receiving, from one or more image capture devices, data indicating the position of one or more objects in the treatment environment. Based on the position data, the controller defines one or more exclusionary zones from which the radiotherapy equipment is excluded. Each zone has a buffer area surrounding one or more of the objects. The controller further directs the radiotherapy equipment such that a radiotherapy treatment plan is delivered without the equipment entering into the exclusionary zones.

Abstract

The disclosed systems and methods for Image-Guided Radiation Therapy (IGRT), utilizes 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-optimization, fluence optimization 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.

Abstract

A method of calibrating a positioning system in a radiation therapy system which includes a radiation therapy unit having a fixed radiation focus, includes irradiating a calibration tool having at least one reference object, capturing at least one two-dimensional image including cross-sectional representations of reference objects of the calibration tool and determining image coordinates of the representation of each reference object. Based on the reference objects' image coordinates, positions of the reference objects in the stereotactic coordinate system relative to an origin of the calibration tool and the position of the origin of the calibration tool relative to the imaging unit, a position difference between the position of the calibration tool in the stereotactic coordinate system and a position of the calibration tool in an imaging system coordinate system including a translational and rotational position difference is calculated.
