sir how to find the tb in the xray
Are you a medical doctor? Because if you are not, you may not understand unless you undertake a course in medicine which teaches about chest X-rays. (I presume you are asking about chest X-rays) But if you are a doctor, TB can manifest in any which way on CXR - normal, nodule, mass, collapse, consolidation, cavity, Hilary LN enlargement, pleural effusion, pericardial effusion, etc.
