Is that a real one or a bogus one ?

I guess bogus.

real.

Bogus

The shading of the greys are reversed. You can see tissue, including a penis on film. This image is just a crappy image and has been butchered. The more dense the bone is, the whiter it will appear on film. A human skull does not appear that dark. The teeth in the jaw look horrible on that image. There's no definition of the teeth on the maxillary (upper) right side, which either the person moved and blurred the image, or the image was doctored. If the person moved, the lower right teeth would be blurred also. They aren't. There's a bridge on the lower right side replacing the 2 missing premolars, but there is no real definition of the canine or other lower anterior teeth. The roots and pins are not correct shades of grey. The tongue is missing. Neck muscles do not appear like that on film. The details are all reversed on the film. You can see details of the fingers, parts of the jaw, but not on the penis?

Cephalometric, panoramic, x-rays do allow for you to see the nose, lips, and chin. On these films and periapicals, you can see nerves in individual teeth and the nerves in both jaws. If you can see the nerve paths in the jaw, you would also be able to see the nerves and blood supplies in the penis. The image has his penis as transparent and without detail.

I never knew that you studied medicine and physics, Panky.....

Panky, I was thinking about a lot of those too. But what made me guess bogus was the guys pubic hair. Hair doesn't show up on screen. Oh and where are his bones? The "blower" is all bones and the "blowee" is all......non boney. Maybe, but I don't think so

Feynman??? Don't keep us guessing!

Wow, an X-ray saavy gal !

I don't really know, but methink its a lot of photoshopping from real x-rays.

All of Panky's observations are real, however, the image being in negative from regular x-ray means very little.


To obtain imaging of the flesh, you need low energy. A mamograph, IIRC, runs at around 40KVolts of energy or less.

At low energy, you'd see finger bones as big blocking objects.

You barely see the bones in the hand so the hand must have been taken at higher energy, so taht the rays punched through. But at high energy, you wouldn'd see the flesh. The trick ? Methink the guy dipped his hand in baryum. That explain why you see the fingernails and the cuticle areas as blocked, standing out. Otherwise, you'd see only bones. Still, this is unsatisfactory as an explanation because you'd see a blocked edge around the fingers if they had been dipped in baryum. They were probably wiped off afterward.


Radiopaque (baryum) was probably also rubbed lightly on pubic hair of the guy to appear that much, for there is no chance in hell you could get to see hair otherwise.

Methink that this pic is a composite of three or four images. The guy's dick at meduim energy with his pubic hair rubbed with baryum, the hand at high energy dipped in baryum, and the skull, possibly a superposition of high energy (bones only) and low energy shots flesh with skulls blocked out)

All that photoshoped into one.

And then, the image was reversed to become positive from the original x-rays negatives.

You can trust me, my father was a doctor.

A radiologist, that is...

I also moonlighted as a medical x-ray machine maintenance guy for several years.

I agree that it is more than one image layered. It makes sense considering the inconsistencies of the details.

Feynman is right about the speed at which certain details are viewable.

I think with the pubic hair and the penis, it was an actual photograph, photoshopped to look like an x-ray image. Doctored image or negative and then combined that with an actual x-ray image of a skull. Maybe the same with the hand since no actual bone structure is visible.

Barium powder could've been used. Metallic powders...


Here is what the photo looks like with the grey scale inverted. Looks more like an actual x-ray. The image(s) are still not correct as far as detail is concerned.

Panky is in dentistry

So I guess she'd know a thing or two about X-ray imagery ... sonsidering she is a licensed radioligist

EEKS !!!

Panky hunnee ... could you go and correct my horrendous spelling ?!?

Fanks !!

yup, wouldn't have a clue about the girl... but my guess on the guy would be definitely a photoshop job... especially considering even his hands have no bones.... must be difficult to pick up stuff.

Not metallic powder. Baryum, the plaster white stuff you drink or that they give you in enema form is a suspension of baryum sulphate in water. Something like well mixed plaster. BTW, gypsum plaster is calcium suphate. So "baryum" IS a fancy form of plaster. They use baryum sulphate because baryum being a heavy metal, it blocks off radiation much better than calcium.

Baryum is toxic, but baryum sulphate being virtually insoluble in water or in the gastric acids (hydrochloric acid), it never gets into the body, goes right through the tube.

Look closer, they do have faint outlays of bones, methink.
