IMAGE ANALYSIS PROCESSES AND METHODS FOR THE EVALUATION OF TAMPON PERFORMANCE
First Claim
1. A method for evaluating the behavior and performance of medical devices in vivo, said method comprising the steps of:
- establishing a database populable with information relevant to a study of the performance of medical devices;
qualifying one or more candidates as participants in said study for evaluating the performance of said medical devices in vivo by subjecting said candidates to an evaluation process that at least determines the ability of said candidates to safely participate in said study and obtains consent from said candidates regarding said participation;
entering information relevant to said candidates and the qualification thereof into said database;
determining detailed protocols and MRI parameter settings relevant to said candidates and said study;
providing an MRI operable in accordance with said protocols and MRI parameter settings and using said MRI to conduct one or more scans of each candidate;
qualitatively analyzing said MRI scans;
quantitatively analyzing at least a portion of said MRI scans by determining physical characteristics of at least one of said anatomical structures and said medical device using image analysis software and data analysis and statistical software packages; and
populating said database with information indicative of said quantitative and qualitative analyses.

Abstract
A method for the study and evaluation of the performance of medical devices in vivo is disclosed. The medical devices are preferably tampons that are observed and evaluated in the vaginal cavities of women during their menstrual cycles in order to obtain data relative to tampon performance for the improvement of tampon technology. The method preferably uses magnetic resonance imaging (MRI), although other types of imaging techniques may be used. The present invention also resides in a method of MRI analysis in which a three-dimensional surface model image of a medical device such as a tampon or similar feminine hygiene product in vivo is created from two or more two-dimensional cross section images and combined with a second surface model image to produce a single image.
