Early screening, “more effective in areas with severe shortages in medical care” is done through features present in smartphones, for image acquisition and processing, according to a statement issued by the institution.
“When mobile phone is connected to a low-cost device that allows the acquisition of the image with the resolution necessary. Subsequently, the images are analyzed using image processing algorithms and data analysis to identify the structures and assist health professionals in the pre-diagnosis of the respective diseases, “he told Lusa the senior researcher of the project, Maria Vasconcelos.
the disease wounds and sleep, which usually appear in Latin America and Africa,” they are mortal “and transmitted to people and animals through the bite of small insects, such as the triatominae and tsetse. “The high number of resulting deaths are associated with late diagnosis.”
With this technology and the low-cost device, both diseases can be detected in initial stages, using microscopic images obtained from analyzing a blood sample from the patient, detecting thereby the respective parasites and allowing its treatment.
in the case of cervical cancer, “the second most frequent cause of death in women in countries developing “the new system use the same inexpensive device for capturing liquid cytology images, assisting the pre-diagnosis of the pathology.
the detection of this type of disease is made, typically by cytological images resulting from tests performed with specialized equipment, “costly and not mobile”, as is the case of the test on human papilloma virus (HPV) and Pap.
to lymphatic filariasis, ” parasitic infection which can cause changes or disruptions in the lymphatic system and an abnormal growth of certain regions of the body, causing pain, disability and social stigma “is also used the image acquisition system to identify the parasites via a blood sample .
This technology is identical to that served as the basis for MalariaScope project – a solution to pre-diagnose malaria – and is now being applied to these diseases, which affect “significantly” mortality countries underdeveloped.
the work to adapt the technology to the screening of the wounds and sleeping sickness, of the cervix and lymphatic filariasis cancer, were developed at Fraunhofer Portugal by students at the University of Engineering College porto, during the school year 2015/2016, with the collaboration of Hygiene and Tropical Medicine Institute and Hospital Fernando Fonseca
