let's brainstorm !! ..measuring the length of the hair follicle under the skin

[okaman]

This is my new curiosity guys!!!

Is there such a device known?
a device will be able to measure the length of hair follicles under the skin! will graphically display or display the value in mm

How can I view the follicles  under skin? with/on a glcd or tft lcd?

With what kind of technology does such a procedure provide successful results?
subcutaneous imaging technologies

(MR) magnetic resonance
ultrasound
lidar
xray
or another device belonging to technology that I haven't met yet.


Is there anyone who owns the original service manual for these devices? or a site address where I can download?
maybe there is free (open source) viewing software or something!

I want to meet/learn with such technologies ,with the right theoretical and practical knowledge.

You cannot even imagine how much I would like to be able to benefit from the experiences of experienced people who have developed projects on such devices / technologies ...

Hi okmn
A very thought provoking post.  I had asked an obstetrician a while ago and he told me that the resolution of the ultrasound device that he used was 0.1mm.  Unfortunately, I don't believe that he knew its frequency of operation.  I would think studying a hair follicle would require a much greater resolution than 0.1mm.  Just a guess.

Here is the address for a paper (Imperial College London) which may have some useful references: https://www.researchgate.net/publication/315518130_The_Hair_Follicle_An_Underutilized_Source_of_Cells_and_Materials_for_Regenerative_Medicine/link/5c9c896992851cf0ae9c8b67/download

Good Luck on your quest.

thank you HAL,
I contunie to search some usefull knowlege for hardware design also software.
