A biopsy apparatus includes a biopsy needle for insertion into an object to be examined in order to sample tissue of a biopsy region in the object, and a spatial range measuring section, which measures a spatial range within which the biopsy needle is capable of sampling the tissue of the biopsy region, based on an image of a phantom that simulates the object, which is captured after the biopsy needle has been inserted into the phantom and a portion of the phantom has been extracted.
