Chennai, Dec 6: Indian researchers have developed a new diagnostic system that can identify illnesses from digitised image of the patient's tongue. The system is of particular use for people residing in remote areas as they do not have ready access to physicians. The tool involves soft inputs such as standard questions about symptoms of the disease and a digitised image of the patient's tongue.
How does the system work?
'The approach basically includes a combination of soft and hard inputs. Soft inputs include a variety of common symptoms such as fever, headache and cough. Each selected disease corresponds to a variety of general symptoms,' said Karthik Ramamurthy from Rajalakshmi Engineering College in Chennai. 'Hard inputs include images of the tongue as it is widely used by the doctor to diagnose the various disorders,' Ramamurthy, who devised the diagnostic system along with his colleagues, added.
The analysis of these inputs are then fed to a neural network or computational model. The neural network is trained with four different algorithms and the image is analysed.
How are the results of this diagnostic tool interpreted?
Here are a few ways in which the results are interpreted:
