Starting from linear CT scanner, straight running to rotational movement (TR system)
In the CT scanner, a radiation source for X-rays, γ-rays and the like and a detector are integrated, and a direct scanning (trans) scan is performed on the subject.
(late operation) to obtain projection data, and then the radiation source and the detector are integrally rotated with respect to the subject (rotate operation). When the rotation operation is completed, the straight traveling operation is started again, and thereafter both the operations are alternately repeated. Finally, when the combination of the radiation source and the detector is one set, the imaging is completed after the rotation of 180 °. In the case of the multi-point type TR system, the combination of the radiation source and the detector has n sets, and in this case, the imaging is completed at 180 ° / n rotation, and the imaging time should be shortened. You can Multi-point straight running ~
Taking a case of a two-point type (two sets of detector and radiation source combination) of a rotational movement (TR type) CT scanner, the TR type CT scanner is as shown in the plan view of FIG. , The radiation detector 1 and the radiation source 2 are arranged on the diameter of the turntable in the Y direction, and the turntable 3 is aligned in the X direction so as to adjust the position in the X direction. It is mounted on the table 5, and further, the X-direction axis-aligning table 5 is mounted on a rectangular Y-direction axis-aligning table 6 which is long in the Y-direction for adjusting the position in the Y-direction. Further, the subject 4 at the center is fixed by a pedestal or the like independently of the detection system, and this is placed through a hole provided in the center of the turntable 3. By the way, since the multi-point TR CT scanner treats multi-point data as if it were one point TR CT scanner, each point (radiation detector, radiation source) is located at the same position from the subject 4. Must be arranged so that. Therefore, conventionally, radiation measurement is performed while moving the X-direction axis alignment table 5 and the Y-direction axis alignment table 6 in parallel in the X and Y directions, and the radiation measurement data and the position data obtained by the position sensor 7 are obtained. It is converted into digital data by the A / D converter 10 via the signal cable 8 and is taken into the CPU 11, and the external output 12
Based on the position displayed in and the distribution of radiation measurement results,
A person judges and positions the object (the detector 1 and the radiation source 2 are arranged so that the subject 4 comes to the center of rotation).
