When a doctor examines a freckle or mole for signs of skin cancer, s/he often asks if it's grown or changed over time. This is always a question that catches one off guard, as it's not really something you'd notice.
I propose a normal paper scanner with a very large glass bed. One climbs on, gets
scanned, then rolls a bit, etc. until their entire body has been scanned. The technician then saves a medium-resolution picture of all of the scans and a high-resolution picture of anything suspicious to a CD to compare with future scans.
Yes, I know full body PET scans exist, but they are ~$1,000 per scan, plus don't really provide data useful for this purpose. A full body scanner should be quite inexpensive to produce (using nearly off-the-shelf components), and only take a half hour or so of a skilled technician's time.
Oddly enough, inspired by "Mole huters"

A less expensive version involves your work photocopier when you think you're alone. |
|
| |
What's wrong with just taking some photographs? |
|
| |
Adding conditioner gives that scanner
full body and a healthy shine. |
|
| |
You could post the images on your homepage for the education and entertainment of all. |
|
| |
BTW, if a PET scan is too expensive, you can volunteer for the Visable Human Project. Entry is free. |
|
| |
Jutta the problem is that if you are single who takes the photos or notices the mole? |
|
| |
Scan with UV light for a nice full body tan. |
|
| |
[jutta] The problem is picture resolution and judging the size of a mole. Scanners can grab much higher resolution than even a fairly close-up picture, and the size of an object pressed on the glass bed is known to a fairly high precision. A full body picture wouldn't give you much information at all. |
|
| |
I guess you could take a picture of each seperate mole with some sort of scale right next to it, but: that's a lot of pictures and time, you could miss something that doesn't look very big at the time, and you would have no point of reference to know where this particular picture of a mole was on your body. |

this idea has some merit as a baseline is always a good thing to have when making a diagnosis. (+) |
|
| |
related -- there was a cartoon panel sometime back that made fun of cheap HMO's with a doctor waving a cat over a patient...CAT scan (rim shot). |
|
| |
but as it turns out, dogs have been successfully trained to sniff out skin cancer in patients with near 100% accuracy. (link). they're training them to find prostate cancer too (have a leg up after all that crotch sniffing they do anyways) dog scan might be more practical. |

Worldgineer: reportedly, people using their photocopiers in that fashion is the largest single cause of copier failure, after paper jams. |
|
| |
[DC] And hopefully never the twain shall meet. "You fool! Never use the auto feeder." |
|
| |
[fodder] It's true you won't be able to get everywhere, but you should be able to cover most areas. Problem areas: insides of legs and inside and outside of arms for everyone, and the small of the back and mid front ribcage for generously proportioned clients. |
|
| |
Like you suggest, some moving and rescanning should fix most of these areas. A camera may be needed for the really difficult areas, such as underarms. |

Hmm. Not a scanner, a booth … annually, the patient undresses,
stands in the booth and an array of digital cameras rapidly
image the entire skin surface under standardised lighting
conditions. |
|
| |
Quick, non-invasive, relatively cheap. Imaging can be compared
year on year to detect growth of moles etc. which might be
malignant. |
|
| |
If different spectrum cameras were used in 8th's booth, other baselines and anomalies could be registered against the person. Thermal might be interesting. A cancer dog could work the vents. |
|
| |
This has been a service offered by dermatologists since the 2000s, at least in Croatia. |

Mobile phones are getting powerful enough to make this idea inexpensive and easy to implement (tricorder whistle during scanning is standard). |
