International Classification:

G02B 6/26
G02B 7/00

US Classification:

385 62, 385 90, 385 28, 359896, 24828831

Abstract:

An optical alignment device holds fiber collimators in place with extremely good mechanical and environmental stability. The device includes a ball with a hole traversing the ball, an upper clamping block with a first inner concave spherical surface and a lower clamping block with a second inner concave spherical surface. The hole includes a shape that can accommodate or contact an optical component whose alignment is to be controlled. The ball, together with the enclosed optical component is firmly held between the first and second inner concave surfaces of the clamping blocks, which are tightened against the ball with screws. When firmly clamped within the concave surfaces, the ball is prevented from accidental movement but can still rotate about any axis to align the optical component. Once alignment is achieved, the optical component and the ball are secured in place by epoxy, glue, solder or other suitable adhesive.

International Classification:

A61B 5/055
G01R 33/48
G01R 33/561

Abstract:

A method may include obtaining a plurality of imaging signals collected by applying a wave encoding gradient to a region of interest (ROI) of a subject. The method may also include obtaining a plurality of auxiliary signals associated with the ROI. The method may also include obtaining a point spread function corresponding to the wave encoding gradient. The method may also include determining, based on the plurality of auxiliary signals, temporal information relating to at least one temporal dimension of the ROI. The method may also include determining, based on the plurality of auxiliary signals, the plurality of imaging signals, and the point spread function, spatial information relating to at least one spatial dimension of the ROI. The method may also include generating at least one target image of the ROI based on the temporal information and the spatial information.

Abstract:

A method for medical imaging may include obtaining a plurality of successive images of a region of interest (ROI) including at least a portion of an object's heart. The plurality of successive images may be based on imaging data acquired from the ROI by a scanner without electrocardiography (ECG) gating. The plurality of successive images may be related to one or more cardiac cycles of the object's heart. The method may also include automatically determining, in the plurality of successive images, target images that correspond to at least one of the one or more cardiac cycles of the object's heart.
