X光是一种重要的医疗助手。X光射线最易于穿透软组织,但也易于被骨骼等高密度组织所阻。因此,在X光照片上可以反映出不同密度组织的图象。X光还可用来研究肿瘤,但是,肿瘤和一般健康组织的密度相差不大,所以肉眼很难分辨出来,但用彩色显像密度计可以克服这个困难,它可以把黑白X光照片变成彩色照片,把一束强大的光 X光是一种重要的医疗助手。X光射线最易于穿透软组织,但也易于被骨骼等高密度组织所阻。因此,在X光照片上可以反映出不同密度组织的图象 X-ray is an important medical assistant. X-rays are most likely to penetrate soft tissue but are also easily blocked by high-density tissue such as bone. Therefore, X-ray images can reflect the different density of the organization’s image. X-rays can also be used to study tumors, but the density of tumors is almost the same as that of normal healthy tissues, making them hard to discern with the naked eye, but the difficulty with color imaging densitometers can be overcome by turning black and white X-rays into color Photo, a powerful beam of light X-ray is an important medical assistant.
