'uncoil' a spiral

I have a series of points on a 2D plane that can be modeled as a
section of an Equilingual (logarithmic) Spiral. I would like to
transpose the point coordinates so that the points lie on a straight
line.

I have written a function that model the points on the circumference of
a circle and then converts the point coordinates into polar coordinates
(using cart2pol). However, the fit is not good enough.

How can I write a function that models the points as a section of a
spiral instead?

Grateful for help!
