Dilation techniques are methods used to enlarge or expand structures in various fields, such as medicine and mathematics. In medicine, dilation often refers to procedures that widen blood vessels or other tubular structures, improving blood flow or facilitating medical interventions. Common examples include balloon angioplasty and cervical dilation during childbirth. In mathematics, dilation is a transformation that alters the size of a geometric figure while maintaining its shape. This is achieved by multiplying the coordinates of the figure by a scale factor. Dilation can be applied in various contexts, including geometry and computer graphics, to create larger or smaller versions of shapes.
