Definition of Stereotactic

Stereotactic: Stereotactic refers to precise positioning in three-dimensional space. For example, biopsies, surgery or radiation therapy can be done stereotactically.

In a stereotactic needle biopsy, the spot to be biopsied is located three-dimensionally, the information is entered into a computer, and the computer calculates the information and positions a needle to remove the biopsy sample.

In stereotactic surgery, a system of three-dimensional coordinates is used to locate the site to be operated on.

In stereotactic radiotherapy, a number of precisely aimed beams of ionizing radiation are aimed from diverse directions and meet at a specific point to deliver the radiation treatment to that point.
