Journey from aPhotograph to Diagnosis

A software developed by Purdue University engineers, simply takes a picture of patients' inner eyelids to measure the amount of hemoglobin in the blood accurately. The team continues working hard to integrate this software into a mobile app. The purposes of the application are to help with early diagnosis and treatment of the diseases while reducing the disadvantages of clinics in developing countries and patients who cannot afford blood tests.

Young Kim, an associate professor of Biomedical Engineering at Purdue University, states that this technology will not replace traditional blood tests but suggests that it could benefit by speeding up the processes. Kim's team has developed an algorithm that converts low-resolution smartphone photos into high-resolution digital signals. This application provides great convenience as it does not require extra equipment to measure hemoglobin levels.

The application under development includes the sync feature of smartphones to stabilize the image quality and guides to keep the distance between the camera and the eyelid. Regardless of the skin colors of the patients, the software can get valid results.

In a separate clinical study, the team gets help from this app to assess patients' hemoglobin levels in their blood at the University of Indiana- Melvin and Bren Simon Cancer Center. They are also working with Shrimad Rajchandra Hospital in India to improve the alghorithm.
