    摘要： A method of performing physiological gating in a medical procedure includes acquiring a sequence of images having at least a first image and a second image of a target region, determining a first composite image based on the first and second images, and gating a medical procedure based on the composite image. A method of performing a medical procedure includes providing a plurality of templates, each of the templates having an image and treatment data, acquiring an input image, registering the input image with one of the templates, and performing a medical procedure based on the treatment data of the one of the templates that is registered with the input image.

    摘要： A method for collecting computed tomography (CT) image data includes determining a number of intervals N into which a respiratory cycle is to be divided, determining a number of respiratory cycles M to be covered in one gantry rotation, and rotating a gantry to collect at least M x N sets of CT image data of at least a portion of a patient, wherein each set of the CT image data corresponds to a phase of a respiratory cycle.
