Title:
TOMOGRAPHY DEVICE CALIBRATION METHOD AND TOMOGRAPHY IMAGE SUPERPOSITION METHOD
Document Type and Number:
WIPO Patent Application WO/2007/037307
Kind Code:
A1
Abstract:
[PROBLEMS] To convert position data corresponding to tomogram data acquired
from a tomography device into position data of a common coordinate system between
different tomography devices and superimpose the data. [MEANS FOR SOLVING PROBLEMS]
An optical tracking device (3) is prepared and a marker (4) which can be detected
by the tracking device is mounted on a gantry (1). A calibration jig having a similar
marker (61) and a ray source (62) which can be detected by a gantry detector is held
by a holding device (2). Position data on the both markers (4, 61) when scan is performed
are acquired by the tracking device so as to obtain a transformation matrix TG→P
for converting the position data of the gantry coordinate system CG
into position data of the scanner coordinate system CP of the tomography
device. Images having position data of the scanner coordinate system CP
are superimposed on each other.
