Apparatus and methods are provided for positioning a needle or cannula of a biopsy device for insertion into a tissue mass by correlating, in real-time, the actual needle or cannula position prior to insertion with its probable trajectory once inserted. In a preferred embodiment, a biopsy device support block is mechanically coupled to an ultrasound transducer to provide alignment of the biopsy device with the ultrasound image in at least one plane. Continued ultrasound scanning of a selected trajectory may be provided to assess depth of penetration of the needle or cannula of the biopsy device, when inserted.
