Abstract:
Systems and methods for efficient and automatic determination of radiation beam configurations for patient-specific radiation therapy planning are disclosed. According to an aspect, a method includes receiving data based on patient information and geometric characterization of one or more organs at risk proximate to a target volume of a patient. The method includes determining automatically one or more radiation treatment beam configuration sets. Further, the method includes presenting the determined one or more radiation beam configuration sets via a user interface.
Abstract:
A system and method for automatically generating radiation therapy treatment plans including one or more processors configured to capture geometries of organs at risk and a target volume specific to a subject, and use a shape-based algorithm to mine (152) a knowledgbase (38) of previously constructed treatment plans for similar geometries to the subject. The system and method interfaces (154) dosimetric information from a plan with a similar geometry as a patient specific starting point for a progressive tuning optimization algorithm resulting in fewer iterations. The progressive tuning algorithm (156, 158, 162) generates an optimized treatment plan. The optimized plan is evaluated against treatment goals. Trade-off plans are generated (164) to create alternative plans according to unmet treatment goals.
Abstract:
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.
Abstract:
Brachytherapy radioisotope carrier systems and methodology for providing real-time customized brachytherapy treatment to subjects with tumors difficult to control using conventional radiation therapy techniques. The invention generally relates to devices, methods and kits for providing customized radionuclide treatments, to help cure, slow progression or regrowth, or ameliorate the symptoms associated with tumors.
Abstract:
The invention relates to a HDR brachytherapy system comprising an ultrasound sensor for being arranged at the location of a brachytherapy catheter (12), wherein the ultrasound sensor is adapted to generate an ultrasound signal based on ultrasound radiation, which has been sent by an ultrasound imaging device preferentially comprising a TRUS probe (40) and which has been received by the ultrasound sensor. The position of the ultrasound sensor is determined based on the generated ultrasound signal, and based on this position of the ultrasound sensor the pose and shape of the brachytherapy catheter and/or the position of a HDR radiation source are determined. This allows for a very accurate determination of the pose and shape of the brachytherapy catheter and/or of the position of the HDR radiation source, which in turn can lead to an improved HDR brachytherapy.
Abstract:
A medical data processing method for determining a target set comprising at least one irradiation target in a patient's body for radiation therapy treatment by means of a treatment device constituted to treat the at least one target by means of one or more sub- beams during a treatment time, the one or more sub-beams constituting at least one treatment beam which is to pass through the at least one target in accordance with a treatment plan during the treatment time, the method comprising the following steps and being constituted to be executed by a computer: a) acquiring (S 1.1 ) critical area; b) acquiring (S 1.2) target data; c) acquiring (S 1.3) treatment beam constraint data; d) acquiring treatment beam criteria data (S 1.4); and e) determining (S4), based on the critical area data, the target data, the treatment beam constraint data and the treatment beam criteria data, target set data describing spatial information on at least one irradiation region.
Abstract:
Disclosed are various embodiments for assessing machine trajectories for collision avoidance. A three-dimensional model of a patient based at least in part on data received from a three-dimensional imaging device is generated. The three-dimensional model of the patient is aligned with a coordinate system of a three-dimensional model of a radiation treatment machine. It is then determined whether a collision between the patient and the radiation treatment machine will occur at each one of a series of control points of the radiation treatment plan.
Abstract:
The present invention proposes a method for automatically creating a dose prediction model based on existing clinical knowledge that is accumulated from multiple sources without collaborators establishing communication links between each other. According to embodiments of the claimed subject matter, clinics can collaborate in creating a dose prediction model by submitting their treatment plans into a remote computer system (such as a cloud-based system) which aggregates information from various collaborators and produces a model that captures clinical information from all submitted treatment plans. According to further embodiments, the method may contain a step where all patient data submitted by a clinic is made anonymous or the relevant parameters are extracted and condensed prior to submitting them over the communications link in order to comply with local regulations.
