腳跟效應(Heel Effect)
靠近X光管陽極端的X光光子,會比陰極端的X光光子強度低,且越靠近陽極X射線輻射強度下降越多的一種現象,這是由於光子打到的物體是多層的晶格,所以不同角度下打入會在不同的晶格層被散射。舉例說:若打入晶格的深處,也就是經過晶格的路徑較長的話,散射出的X光能量就較低,又此低能量的X光子會出現在靠近陽極端的地方,反之亦然。所以人體照射X光時,腳朝陰極端,頭朝陽極端。所以在入射角度小於7度時,陽極端的腳跟效應已經明顯到不可忽略,陽極端的強度急速變弱,陰極端的強度稱微增強。

陽極有些地方電子聚集,稱作焦點(Focusing Spot),大多是鎢或是鎢鍊合金,電子打到焦點上會產生輻射,99%的輻射被吸收再以熱的形式釋出,1%轉成有用的X光,順便提一下,陽極一直被電子撞擊會產生許多小坑,這些小坑增加X光的散射,使很多X 光子偏離有用射束的方向,造成X光強度變弱,請注意會引發空間電荷效應(space charge effect),在陰陽極之間電位差極小時,便不足以讓電子心無旁騖的奔向陽極,所以在陰陽極形成一大團電子雲,而心發射出來的電子又同性相斥,回到陰極(Cathode)。

鎢絲線圈(Coil of Tungsten Wire),以線圈狀裝在聚焦杯內,而線圈的長度半徑,聚焦杯的大小形狀都會影響到焦點的大小,焦點對於X光影像品質影響非常大。通常X光射線管(X-ray tube)裡有兩組燈絲,一粗一細,粗的用在電流大的情形,細的用來產生小的焦距。兩組燈絲都聚焦在陽極的同一個地方,當鎢絲(即燈絲)被加熱到白熱化時,會從表面射出電子,這時候電子受到陽極吸引(正電壓),而形成電子流。
