The body consists entirely of an integral molding of polyethylene foam in the form of a generally channel-shaped cross-sectional member open at both ends. The bottom wall 11 is plate-shaped with a flat surface and a curved back surface, and one end is narrow. Side walls are arranged along both side edges of the bottom wall and perpendicular to the bottom wall. The side walls 12, 12 are formed at a height such that the patient's head is almost buried in the narrow part of the bottom wall 11 to form a head accommodation space for accommodating the infant patient's head. , is formed at a height such that the patient's torso is almost buried in a wide part of the bottom wall 11 at a distance sufficient to accommodate the infant patient's arm from the head accommodation space, and the infant patient's torso is It forms a body accommodation space that accommodates the.

る。 As shown in FIGS. 6 and 7, this infant patient fixation device has a patient table 1 whose main body is a CT device.
6 and the bottom wall 11 is tied to the table 16 by bands 17 and 18,
Installed in CT equipment. As shown in FIG. 8, the infant patient 20 has his head placed in the head accommodation space formed between the side walls 12, 12, and his torso placed in the side wall 13,
Furthermore, the infant patient's arms are accommodated in the part where the side wall is not provided between the head accommodation space and the torso accommodation space, and both hands are accommodated in the body accommodation space formed between the head accommodation space and the body accommodation space. It is located and housed on the outer surface 14 of the side wall 12 . Then, the three bands 21, 22, and 23 are placed around the head, chest, and legs of the patient 20, and as shown in FIG. and fix it to the table.

きわめて少ないものとなる。 For CT imaging, the required area to be imaged for infant patient 20 is CT.
This is done by moving the table 16 to match the x-ray flux of the device. Obtained CT
The patient image in the image shows linear artifacts that tend to occur on the tangents of the outer surfaces 14 and 15 of the side wall portions 12 and 13, that is, artifacts that occur on the tangents of each point on the contour line forming the outer surfaces 14 and 15. is accommodated in the state of being substantially buried in each of the accommodation spaces, and the outer surfaces 14 and 15 are inclined from the upper edge toward the lower edge, so that they do not intersect the patient's image. Therefore, the resolution can be extremely high. In addition, the infant patient 20 has his head and hands held by the side wall portion 12 in the infant's natural position more than ever before, and the band 21
The patient's chest and abdomen are held between the side wall portions 13 and tied with a band 22, and the legs are also tied with a band 23, completely preventing movement. This results in very few facts.

きる。(Effects of the invention) As described above, in the infant patient fixation device of the present invention, each part of the infant patient's head, arms, both hands, torso, and legs is fixed to the patient's body axis on each side wall provided on the main body. The infant is almost buried in each of the accommodation spaces formed in a triangular shape, with the upper edge being the apex and the outer surface being an inclined surface whose cross-sectional width increases as it approaches the bottom wall from the apex. Since the patient is housed and fixed in a natural body position, artifacts generated in the longitudinal direction of the outer surface do not intersect the patient image area, making it possible to obtain high-resolution CT images.
