Document Type and Number:
Japanese Patent JP2001522037
Kind Code:
A
Abstract:
The invention relates to a device for referencing a system of coordinates (1) in space (2). It comprises a body (4) that is suspended in space (2), and which is aligned in a local gravitational field (3). Further, the device has at least two first components (5) that emit electromagnetic or acoustic waves that are located at a distance, A, from each other. Second components (5) for detecting acoustic waves or a magnetic field may also be arranged on the body (4) at a distance, A, from each other, instead of the first components which emit the electromagnetic or acoustic waves. Advantageously, the device and first components are incorporated in a Computer Assisted Surgery (CAS) System which includes the second components. Thus, the second components may interact with the first components, while the CAS system includes a plotting unit for determining the spatial coordinates of the body.
