Title:
X-RAY DEVICE.
Document Type and Number:
WIPO Patent Application WO2000036403
Kind Code:
A3
Abstract:
An X-ray device (1) includes a C-shaped arm (2), a first end of which supports an X-ray source (3) and a second end of which supports an X-ray image pick-up device (4). The C-shaped arm (2) is pivotable about a pivot axis (A2) relative to a carriage (5). The carriage (5) is tiltable about a tilting axis (A5) relative to a guide (9). The guide (9) is rotatable about a propeller axis (15). The tilting axis (A5) extends at an angle relative to the propeller axis (15). A leverage point (H) on the propeller axis (15) is situated near the tilting axis (A5). The mass center (M2) of teh C-shaped arm (2) is situated on the pivot axis (A2). The mass centers (M2, M5) of the C-shaped arm (2) and of the carriage (5) are situated on a leverage line (16) which extends at least substantially through the leverage point (H). The mass centers (M2, M5) of the C-shaped arm (2) and of the carriage (5) are situated to both sides of the leverage point (H). The ration of the distance (L2) between the mass center (M2) of the C-shaped arm (2) and the leverage point (H) to the distance (L5) between the mass center (M5) of the carriage (5) and the leverage point (H) is substantially equal to the ratio of the mass (M5) of the carriage (5) to the mass (M2) of the C-shaped arm (2).
