Abstract: An image correction method, applicable to an image to be corrected having two boundary, comprises: extending a first and a second straight line in the image to be corrected to generate a first and a second extended straight line with both of them intersecting the first and second boundary to generate multiple intersection points; performing an extrapolation process based on multiple intersection points, center points of the two boundaries, and a half side length to generate a first and a second extrapolation line, rotating the image to be corrected when the first and second extrapolation lines have different slope values to generate a preliminary corrected image; and performing a Keystone correction process when the first and second extrapolation lines have same slope values or when obtaining the preliminary corrected image to generate a corrected image.

Abstract: The present invention discloses a catheter system, comprising: a catheter head having a lumen, a proximal end and a distal end, and an opening positioned at a bottom of the distal end; and a rotatable inner tube having a lumen positioned in the lumen and at a proximal end of the catheter head, the inner tube including a front end having an arcuate opening; wherein the rotatable inner tube can be rotated so that the arcuate opening thereon can be made to engage or disengage with the opening at the bottom of the distal end of the catheter head. The invention also provides a catheter system and method for re-entry of a vascular false lumen into a true lumen in a quick, accurate and low-risk way.

Abstract: This document relates to preserving input data. One example includes obtaining a request that a service perform processing on input data to produce an output representation of the input data. This example also includes applying criteria to the request, and preserving the input data responsive to determining that the criteria are met.
