Disclosed herein are radiotherapy methods and systems that can display a workflow-oriented graphical user interface(s). A method comprises presenting a plurality of pages for display, each corresponding to a stage of a radiotherapy treatment for a patient; in response to receiving an indication that a surface of a patient is aligned, retrieving, from a radiotherapy file, a first image of an internal target aligned in accordance with treatment attributes; receiving a second image of the internal target; overlaying on a first page of the plurality of pages, the first image and the second image, the first page displaying a direction to position the internal target in the second image to align with the internal target in the first image; and when the internal target is aligned, presenting for display a second page of the plurality of pages corresponding to a subsequent stage of the radiotherapy treatment for the patient.

The present invention relates to linear, straight through electron beam machines that incorporate a rotary coupling system to easily attach and manually or automatically rotate field defining members such as applicators and/or shields to the electron beam machines. The rotary coupling systems also incorporate functionality for using different kinds of optical signals to automatically provide illumination, reference mark projection, and/or distance detection. The optical signals generated downstream from heavy collimator components and are transmitted along the central axis of the field defining elements so that function and accuracy are maintained as the components rotate.

Disclosed is a bore based medical system comprising a camera carrier configured to be mounted in the bore based medical system and configured to monitor and/or track patient motion within said bore based medical system during radiotherapy, the bore based medical system comprising a rotatable ring-gantry configured to emit a radiotherapy beam focused at an iso-center of the bore based medical system, wherein the ring-gantry is configured to rotate at least partly around a through-going bore having a front side and a back side, configured to receive from said front side, a movable couch configured to be moved into and out from the through-going bore, wherein further the through-going bore comprises an inner side facing an inside of the bore, and wherein the camera carrier is configured to be mounted inside the bore in connection with the inner side of the through-going bore.

A computer implemented method of treatment targeting includes receiving magnetic resonance (MR) images of a subject including a target region, generating at least one contour of at least one surrogate element apart from the target region in the MR images, and determining a location of the target region in each of the MR images based on a location of the at least one contour in the MR images.

A method and apparatus for position detection, and a radiotherapy system are provided. The radiotherapy system includes: a treatment couch, a positioning apparatus, an optical tracking system and a computer; the positioning apparatus disposed on the treatment couch, and at least one reference point provided on the positioning apparatus; the optical tracking system disposed above the treatment couch and configured to detect relative positioning between a mark point set on a treated part of a patient and the reference point, determine deviation between the relative and reference positions, and send the deviation to the computer. The computer is configured to determine whether to adjust a position of the treatment couch based on the deviation and deviation range. The system provided by the present disclosure avoids the influence of patient movement on the accuracy of treatment, and prevents a treatment beam from damaging normal tissues of the patient.

An optimal bicycle frame size based on operational characteristics provided by a rider when riding a dynamic fit unit is determined. A best-fit bicycle frame size that is a closest match to the optimal frame size is determined. At least one of the optimal X,Y location of the bicycle's handlebar relative to the bottom bracket, and the optimal X,Y location of the bicycle's seat relative to the bottom bracket, is determined. A stem and spacer from a list of available stems and spacers that will best fit between the head tube of the best-fit frame and the optimal X,Y location of the handlebar is determined. A seat post from a list of available seat posts that will best fit between the seat tube of the best-fit frame and the optimal X,Y location of the seat is determined. A list of the best-fit frame, the best fit stem and spacer, and the best fit seat post, is produced.

Systems, devices, and methods are presented for automatic tuning, calibration, and verification of radiation therapy systems comprising control elements configured to control parameters of the radiation therapy systems based on images obtained using electronic portal imaging devices (EPIDs) included in the radiation therapy system.

These teachings provide for accessing stored patient surface information for a given patient and geometry information for a patient support setting. These teachings then provide for generating a patient-position solution that will avoid collisions during a subsequent administration of radiation treatment as a function, at least in part, of that patient service information and the geometry information. That patient-position solution is presented via a user interface in conjunction with conducting at least one simulation scan of the given patient using the patient support setting. To avoid collisions, these teachings will also support an option to modify the treatment plan rather than the patient position using the patient image model shown in the user interface.

Subject positioning systems and methods are provided. A method may include obtaining first information of at least part of a subject when the subject is located at a preset position, and determining, based on the first information, a first position of each of one or more feature points located on the at least part of the subject. The method may include obtaining, using an imaging device, second information of the at least part of the subject when the subject is located at a candidate position. The method may further include determining, based on the second information, a second position of each of the one or more feature points, a first distance between the first position and the second position for each feature point of the one or more feature points, and a target position of the subject based at least in part on the one or more first distances.
