Abstract
Apparatus and methods are described including, while an endoluminal data-acquisition device is being moved through a lumen, acquiring a plurality of endoluminal data points of the lumen using the endoluminal data-acquisition device. The endoluminal data points are displayed in a stack, and are co-registered to respective locations along the lumen in an extraluminal image of the lumen. Based upon the co-registering of the endoluminal data points to respective locations along the lumen in the extraluminal image of the lumen, a parameter of a portion of the lumen that corresponds to a portion of the stack of endoluminal data points is determined. An output is generated in response thereto. Other applications are also described.

145. Apparatus comprising:
-
an endoluminal data-acquisition device configured to acquire a plurality of endoluminal data points while moving through a lumen of a subject; a display; and at least one processor configured; to generate a stack of the endoluminal data points, to co-register the endoluminal data points to respective locations along the lumen in an extraluminal image of the lumen, based upon the co-registering of the endoluminal data points to respective locations along the lumen in the extraluminal image of the lumen, to determine a parameter of a portion of the lumen that corresponds to a portion of the stack of endoluminal data point, and to generate an output on the display, in response to the measured parameter. - View Dependent Claims (146, 147, 148, 149, 150, 151, 152)

153. A method for use with an endoluminal data-acquisition device configured to acquire endoluminal data points while moving through a lumen of a subject, comprising:
-
while the endoluminal data-acquisition device is being moved through the lumen, acquiring a plurality of endoluminal data points of the lumen using the endoluminal data-acquisition device; displaying the endoluminal data points in a stack; using at least one processor, co-registering the endoluminal data points to respective locations along the lumen in an extraluminal image of the lumen; using the processor, based upon the co-registering of the endoluminal data points to respective locations along the lumen in the extraluminal image of the lumen, determining a parameter of a portion of the lumen that corresponds to a portion of the stack of endoluminal data points; and using the processor, generating an output in response to the determined parameter. - View Dependent Claims (154, 155, 156, 157, 158, 159, 160)
