$LLBO Chronodynamics had completed two rounds of testing involving approximately 350 women. The first proof-of-concept trials were conducted at The Ohio State University’s Oncology Hospital. The next round of study was conducted at Green Memorial Hospital, Dayton, Ohio. The Green Memorial Principal Investigator was Dr. Ronald Fletcher. Dr. Fletcher was head of oncology at Green Memorial and former head of the Health Department for the State of Ohio. The last round of patient testing with 188 subjects was conducted at Clem Plam Breast Clinic, La Plata, Argentina under the direction of Dr. Marten Laguens, a noted Argentinian Pathologist at the University of La Plata. The System proved to have similar accuracy to mammography across all tissue types. In addition, the system found tissue abnormalities, where the biopsy proved the state of cancer, in patients with smaller tumors than normally visible with mammography, and with those difficult to image or "dense breasted" populations that mammography was simply unable to ascertain.
