Further Help on Registration

[(s) Jodie Nicholls]

Hi all,

I have two mammogram images that i need to register. The problem is that the images are from a right breast and a left breast, and so the technique of using SIFT and bunwarpj, as was kindly suggested by some of you previously, works for the previous images where the breast was used, but not for these, as that technique tries to find landmarks inside the border and of course there aren't any as they are not the same breast.

I was wondering if there was a way to do registration for the Left/Right image pairs where we draw a border around the breast and use that to register?

Here is a link to the images in question:

This first image is the left breast which i have manually drawn a border around.

This second image is the right breast.

I would really appreciate any help that you could give.

Many Thanks

Hi,


You would of course wish to register the right with a mirror image of the left.

Best regards,
Karl Hoover

Hello,

Thank you for your input. Yes i have rotated the right breast so they are mirror images, but when i try to register them, using either bunwarpj or turboreg, there is a lot of movement around the edges, in other words i cannot get the edges of the images to line up. So i was wondering if there was a way to possibly draw a border around the breast as demonstrated in the first image, and use these borders to register the image in the hope of getting rid of this movement problem?

Thank you for your time and help

Kind regards

Jodie

It is very doubtful that two mammographic images will be an exact match whether they are of the same or the opposite breast.  There are to many variables: patient positioning, vagaries in breast size, degree of compression, etc.  I think that you will not be able to perfectly match the two.  I have been performing mammography since 1986.

Dear Dr Hartung

Thanks very much for your help!

Yes I realise that it will not be possible to do a very good registration. I was mostly wondering about this possible way of doing registration by trying to match up polygonal *regions* in the images rather than *points*. There will obviously be no possible match-up with points, but a morph of the contents of polygons seems feasible.

Thanks again.

Cheers
Jodie
