Ultrasonics: a window into biomedical science.

Ultrasonics has always been concerned with biomedical research. When the journal started, most applications were in therapy and surgery, but diagnosis soon became dominant. Many key developments received early publication: these included Doppler ultrasound, real-time imaging, tumour neovascularization and, arguably most significant of all, phased array scanning. Now in its thirtieth year of publication, Ultrasonics has contributed greatly to the development of biomedical science and it promises to have an important continuing role.
