Systems, devices, and methods for dosimetric verification of radiation therapy treatments by selective evaluation of measurement points. Systems, methods, and computer program-products for providing dosimetric verification of radiation therapy treatments by evaluating measurement points using different evaluation criteria.

Portal dosimetry systems, devices, and methods

The invention relates to tracking pieces () used in the context of tracking movements of hard tissue of a jaw. According to the invention, a tracking piece () to be used in such context is designed to be patient-specific by including in the design of the tracking piece () a surface model representing a part of a person's intraoral anatomy, which surface model is generated based on imaging results acquired by imaging the anatomy.

Tracking pieces for tracking movements of hard tissue of a jaw

An apparatus for use in a treatment planning process or in a treatment process, includes: an input for obtaining a parameter representing a number of beam on-off transitions; and a treatment planner configured to optimize a treatment plan based on parameter representing the number of beam on-off transitions. An apparatus includes: an input configured to obtain a width of a gating window for a treatment plan; and a gating window adjustor configured to adjust the width of the gating window during a treatment session. An apparatus includes: a dose calculator configured to calculate doses for different treatment variations; an evaluator configured to evaluate treatment acceptance criteria against the calculated doses; and a delivery limit module configured to determine one or more limits for one or more delivery parameters based on an evaluation of the treatment acceptance criteria by the evaluator.

Systems, devices, and methods for quality assurance of radiation therapy

A radiation-delivery treatment plan includes a first value for a limit as pertains to motion compensation-based adjustment of a radiation-delivery parameter during a first portion of a radiation treatment session as well as a second value for that same limit during a second, different portion of the treatment session. By one approach, the radiation-delivery treatment plan selects between this first and second value as a function of a preselected parameter. Examples of such parameters include, but are not limited to, radiation-beam orientation parameters (such as a gantry-based parameter) and/or any of a variety of external surrogates.

Method and apparatus pertaining to configuring a radiation-delivery treatment plan

Embodiments of the present invention are directed to methods and a mechanism for manipulating images generated by radiotherapy machines used in radiation diagnostic and treatment applications. In one embodiment, a method is provided for intelligent automatic propagation of manual or automatic contouring across linked (e.g., registered) images and image data sets by acquiring one or more images of one or more image data sets; determining the correlation between the images with respect to identified structures; and generating a deformation map that establishes a correspondence for each point in the source image with a point in the target image. Subsequently, the intelligent propagation mechanism applies this deformation map individually to each structure of the source image and propagates the deformed structure to the target image.

Mechanism for advanced structure generation and editing

The invention relates to tracking motion of a patient's jaw, wherein motion of a tracking item which represents motion of the jaw is followed by at least one camera arranged to a medical x-ray imaging apparatus and wherein the motion detected by the at least one camera is applied on a digital model depicting hard tissue of the jaw. The moving digital model of the hard tissue of the jaw thus generated is shown on a display to visualize movement of the hard tissue.

Tracking motion of a jaw

Embodiments of the present invention are directed to methods and a mechanism for manipulating images generated by radiotherapy machines used in radiation diagnostic and treatment applications. In one embodiment, a method is provided for intelligent automatic propagation of real-time alterations across graphical structures of an image by mapping the relativity between the structures; determining the correlation between the structures and a manually edited structure; referencing a deformation map that maps a correspondence for each point in the original structure with a point in the edited structure and applying a similar relative change throughout the remaining structures in the image.

System for dynamically propagating real-time alterations of medical images

Tracking a motion of a jaw

The invention generally relates to generating digital dental panoramic images from multiple frame images acquired during a dental panoramic imaging scan about a patient's head. This generating includes using information of location and orientation of the x-ray beam and the x-ray detector at times when taking the frames in the procedure of summing information of the frames.
