    摘要： Apparatus, methods, and other embodiments associated with magnetic resonance imaging (MRI) blipped trajectories having varying blip amplitudes are described. One example method includes controlling an MRI apparatus to produce a set of blipped trajectories including a first blipped trajectory having a first blip amplitude and a second, different blipped trajectory having a second, different blip amplitude. The blip amplitudes may be based on a relationship between a trajectory and a reference. The relationship may be, for example, a rotation angle. The rotation angle may be a proxy for information including a gradient trajectory speed associated with a blipped trajectory or an amount of unused gradient energy available while producing the blipped trajectory. The blip amplitudes may be selected to produce incoherent sampling during an MRI acquisition that uses the blipped trajectories. In one example, readout directions may be altered between trajectories to reduce regularity in k-space.

    摘要： The present invention provides a hand held cleaning utensil having an extendable elongate handle with a working head at one end of the handle, the handle being assembled of at least a first length to which the working head is mounted and a second length that is coupled to the end of the first length remote from the working head, and which is adapted to be moved from a first position, in which the second length is stowed alongside or substantially coaxial with the first length but not obstructing the working head so that the utensil may be used, to a second position, in which the second length is substantially aligned with the first length to provide an extended overall handle length.
