Abstract: Embodiments of this application describe improved techniques for operating moveable furniture items. The techniques can include configuring a moveable furniture item such that it will not pivot of tip over during normal operating conditions. The techniques can also include certain passive safety features, such as selecting components that experience a fail condition if a certain threshold condition is reached. In some embodiments, the furniture item can be programmed to operate in various modes, desirable in certain circumstances. The techniques described herein can improve both the functionality and the safety of moveable furniture items.

Abstract: There is provided a basket (10) for receiving, transporting and curing tobacco leaves, the basket having a substantially cuboidal shape, having a base (110), opposing side walls (120, 130) rigidly attached to the base (110), and a back wall (140) rigidly attached to the base (110) and to the side walls (120, 130), the basket (10) being open to the front and to the top.

Abstract: Each image in a first set of images includes respective exposures of an image capture device to a beam of radiation, each of a plurality of components of a radiation delivery system being at respective specified orientations with respect to a three-dimensional coordinate system during each of the exposures. Respective beam images are reconstructed from each of the exposures by drawing a line at a predetermined angle to the first image and through a center of a radiation beam shown on each first image. The reconstructed beam images are combined on a second image.

Abstract: Calibrating the dose response of an image acquisition device comprises comparing a first self-calibration curve to a second self-calibration curve to determine the relationship between the curves; modifying an acquired image based on the at least one difference; and applying an initial calibration to the acquired image, whereby the dose response of the image acquisition device is calibrated.

Abstract: A first self-calibration curve relates a first array image to a first acquired image, the first array image being recorded from application of a first radiation treatment plan to a detector array, and the first acquired image being recorded from application of the first radiation treatment plan to a radiation detector. At least one subsequent self-calibration curve relates at least one subsequent array image to at least one subsequent acquired image, the subsequent array image being recorded from application of at least one subsequent radiation treatment plan to the detector array, and the subsequent acquired image being recorded from application of the subsequent radiation treatment plan to the radiation detector. In some embodiments, the detector array is pre-calibrated to a predefined standard.

Abstract: Optimizing an alignment of a first image having a first set of points and a second image having a second set of points includes selecting at least one point in the first set of points; selecting at least one point in the second set of points, each selected point in the second set of points corresponding to at least one of the at least one selected points in the first set of points; calculating at least one alignment index related to the at least one selected point in the second set of points; and generating an optimization based on the alignment index. Some embodiments further include applying the optimization to at least one of the points selected in the second set of points, thereby optimizing the alignment of the second image with the first image.

Abstract: Methods and devices for calibrating a radiotherapy system are disclosed. The method includes providing a detection medium that responds to exposure to ionizing radiation, and preparing a calibration dose response pattern by exposing predefined regions of the detection medium to different ionizing radiation dose levels. The method also includes measuring responses of the detection medium in the predefined regions to generate a calibration that relates subsequent responses to ionizing radiation dose. Different dose levels are obtained by differentially shielding portions of the detection medium from the ionizing radiation using, for example, a multi-leaf collimator, a secondary collimator, or an attenuation block. Different dose levels can also be obtained by moving the detection medium between exposures. The disclosed device includes a software routine fixed on a computer-readable medium that is configured to generate a calibration that relates a response of a detection medium to ionizing radiation dose.

Abstract: The invention is a system or method for aligning images (the “system”). A definition subsystem, including a first image, a second image, one or more target reference points, one or more template reference points, and a geometrical object. The definition subsystem identifies one or more target reference points associated with the first image and one or more template reference points associated with the second image by providing a geometrical object for positioning the first image in relation to the second image. A combination subsystem is configured to generate an aligned image from the first image and second image. An interface subsystem may be used to facilitate interactions between a user and the system.

Abstract: The invention relates generally to systems and methods for processing radiographic and other medical-related images (collectively “imaging system” or simply the “system”). More specifically, the invention relates to a system for associating particular calibration information with a particular radiographic image. Calibrated images processed by the system can be created from radiographic images and calibration information associated with the radiographic images. In many embodiments, the system includes a user interface that automatically configures itself in accordance with the calibration information embedded with the radiographic image. The system can include a user interface configured to obtain the calibration from the data object.
