Thermography for early detection of cancer

摘要

Cancer is increasing fast nowadays through all over the world. Early diagnosis of cancer is a desirable subject as it can significantly improve the patient's chances of survival. In most cases the cancer is diagnosis using MRI, CT, PET. But, there are several disadvantages associated with high cost, low sensitivity and specificity, and health risks from radioactive. For that reason, significant efforts are being invested to improve the current imaging system. Thermography can offer some advantages. Chief among these are the contact free and low cost for detect cancer. But thermography has some disadvantages associated with low sensitivity for small tumors.In this research develops non contact, safe, high sensitivity, and low cost infrared imaging technique. Experiments were performed using lock in thermography with a small amount of magnetic nanoparticle (MNP) and radiofrequency generator. As a result, highly sensitive infrared thermography can a small amount of MNP be detected by the technique.
