Your examples are a bit small for me to see well (click the link below for tips on uploading images at a size/quality that are suitable to work with). Did you use the Glowing Edges filter? You have an interest in x-ray and infrared images -- have you ever used infrared film or a digital camera with infrared capabilities?
I am able to shoot "near infrared" photos with my Olympus 2100 UZi with a red filter (R72, I think). I know there are some Photoshop techniques for making a normal photo look like infrared. Here's a link to David Jaseck's posts on DPreview explaining his techniques.
