SpectraScience awarded U.S. patent for methods and apparatus for evaluating image focus
Once believed to be important only for bone health, vitamin D is now seen as having a critical function in maintaining the immune system throughout life. The newly recognized disease risks associated with vitamin D deficiency are clearly documented in a report in the December issue (Volume 3, Number 4) of Breastfeeding Medicine, a peer-reviewed

SpectraScience, Inc. has announced that it has been awarded U.S. Patent number 7,469,160 for its methods and apparatus for evaluating image focus.
Jim Hitchin, SpectraScience’s CEO, commented, “This patent is another important addition to our expanding intellectual property portfolio.”
The invention provides methods of focusing an instrument for the acquisition of optical data from a tissue sample. It allows rapid focusing in a diagnostic procedure in which quick data acquisition is desirable. For example, the techniques allow a user to focus an optical instrument quickly enough to obtain data within an optimal window of time. In one version, a user focuses an optical instrument by aligning laser spots projected onto a tissue sample within rings that are superimposed at predetermined locations within the user’s visual field. The invention further allows automatic validation to detect whether the spots are sufficiently well-aligned.
Hitchin added, “Accurate data acquisition and fast focusing techniques are critical for earlier and more effective identification of normal, pre-cancerous or cancerous tissue. This invention will make our screening devices more useful to the physician and, more importantly, more effective for the patient. It allows the LUMA Cervical Imaging System to detect close to 30% more ASCUS/LSIL cervical cancer precursors than colposcopy alone, providing clinicians with a valuable tool in the fight against cervical cancer. In fact, a recent large-scale National Cancer Institute-sponsored clinical trial demonstrated that colposcopy failed to detect 33% of high-grade precancerous lesions in women referred with questionable Pap results.”
SpectraScience holds approximately 60 patents worldwide that have been issued or are pending for its WavSTAT(R) Optical Biopsy and LUMA(R) Cervical Imaging Systems. These non-invasive optical devices are used to diagnose tissue quickly to determine if it is normal, pre-cancerous, or cancerous. The WavSTAT and LUMA Systems are currently approved by the FDA for detecting pre-cancerous and cancerous tissue in the colon and cervix, respectively. An evaluation of the WavSTAT for detection of pre-cancers in the throat (”Barrett’s esophagus”) is being tested.

As testing for high-risk types of the human papillomavirus (HPV) emerges as the gold standard in cervical cancer prevention, scientists are already researching how to determine even more precisely who is most likely to develop the disease and thus are in need of more immediate intervention. Speaking at the EUROGIN (European Research Organization on Genital

Many scientists like to discuss how each form of cancer is a distinct disease with its own causes and its own treatments. But researcher Hartmut “Hucky” Land, Ph.D., takes the opposite approach: He is hunting for the most basic rules that all cancers share to make good cells go bad. His unique, far-reaching effort to
