Louis B. Cady, MD on the Pharmanex Biophotonic scanner & Explanation of the Raman Shift Published on Jul 20, 2013
In this video clip, Dr. Cady presents from the exam room at the Cady Wellness Institute explaining the current generation of the Pharmanex Biophotonic Scanner – the S2 “Everest” model. In addition to reviewing the scanner and antioxidants and their relevance to human mental & physical health and well being, Dr. Cady concludes the video using a Remington hunting flashlight with a set of blue LED’s to demonstrate the Raman Effect.
This hunting flashlight, with regular, red, and blue LED’s, is how hunters use Raman spectroscopy to track injured, bleeding game in the field. The absorption spectrum of hemoglobin (the oxygen carrying molecule in the blood) is interesting. It absorbs strongly in the blue band (410 – 420 nm) and reflects back strongly in the red band (680 – 690 mm). This means that the hemoglobin in the blood drops on the ground show up as bright red when the blue LED light is shone on them because of the Raman shift.
In the case of the Biophotonic scanner, it is carotenoid molecules from which the light is reflected. (Carotenoids are the strong antioxidant molecules that humans get from their diet if they consume colorful fruits and vegetables.) Blue light of 473 nanometers (nm) emitted from the Biophotonic scanner is shot out from the high intensity LED on the scanner. This is then compared to the green light of 510 nanometers which comes back and is counted on the detector built into the scanner. The number of green photons coming back is used by the computer and the computation algorithm to compute the “Raman score” or the “Skin Carotenoid Score (SCS).”
The Skin Carotenoid Score (SCS) can be converted to a more conventional laboratory measurement using the equation: Y = 12703 * X + 5891.7 where “Y” is the skin carotenoid score and “X” is the skin carotenoid score expressions as concentration of carotenoid in micrograms/ml of serum (blood). Thus, 1000 units on the SCS scale is translated into 0.6 ug of carotenoid/ml of blood serum. A reasonable (not optimal) SCS of 40,000 would thus translate into a concentration of 2.4 micrograms/ml of serum of carotenoid.
In the flashlight demonstration, Dr.Cady uses a yellow photographic filter to essentially do what happens when blue photons bounce off of carotenoids: to absorb some of the light energy and cause a shift in frequency from higher frequency (lower number) to lower frequency (higher number). In this case, just like with carotenoids, you can clearly see blue light from the LED’s on the flashlight being transformed into green light.
BioPhotonic Scanner in an Integrated Psychiatric Practice Published on Jul 18, 2013
In this brief video, Dr. Louis Cady, MD, founder and CEO of the Cady Wellness Institute in Newburgh, IN, reviews the rationale behind the use of the Pharmanex BioPhotonic Scanner in an integrated neuropsychiatric practice. This is a lay person’s view of how the technology works, why an antioxidant scan (and score) are so important in psychiatric patients, and Dr. Cady’s impression of the usefulness of this technology in the practice at CWI.
While it is important to note that the BioPhotonic Scanner is not approved as a “diagnostic instrument” by the FDA, and that no supplement or nutraceutical can be used to diagnosed, treat, prevent, mitigate, or cure any disease, at Cady Wellness Institute we find that the use of supplements is critically important to support the structure and function of the human body and to optimize it and its antioxidant defense mechanisms.
