Frequent bouts of epistaxis (nosebleeds) are a classic and often the earliest symptom of hereditary haemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease. This genetic disorder causes abnormal blood vessel formation (telangiectasias) in various organs, particularly the nose, leading to recurrent bleeding.

In an X-ray tube, the filament (cathode) is heated to produce electrons through a process called thermionic emission. This heating is accomplished by a step-down low voltage transformer, which reduces the high voltage from the power supply to a lower voltage suitable for heating the filament. The step-down transformer ensures that the filament receives the correct amount of current to achieve the necessary temperature for electron production.
