Description

A method and position for fixing infrared markers on thermoplastic films Technical Field

[0001] The present invention relates to the technical field of medical auxiliary products, in particular to a method for fixing an infrared marker on a thermoplastic film and the position thereof. Background Art

[0002] Radiotherapy positioning is the focus of clinical radiotherapy and a major factor affecting the effect of radiotherapy. The accuracy of radiotherapy positioning directly affects the effect of radiotherapy. In order to improve the accuracy of radiotherapy positioning, traditional methods such as lead points and cross lines are mostly used in clinical practice, but the accuracy of these methods is not high. Nowadays, with the widespread use of infrared technology in clinical practice, more and more institutions use fixed infrared markers to achieve positioning and positioning. However, due to the non-standard operation of the operators, the stability of the infrared markers is not high, and due to the subjectivity of the operator's experience, the position of the fixed infrared markers is different, which affects the effect of positioning and positioning. Summary of the Invention

[0003] In view of the above problems existing in the fixation of infrared markers, the purpose of the present invention is to propose a method and position for fixing infrared markers on thermoplastic films, aiming to improve the stability of the fixation of infrared markers on thermoplastic films and standardize the position of the infrared marker fixation.

[0004] The technical solution adopted by the method of the present invention is:

[0005] The present invention provides a method for fixing an infrared marker on a thermoplastic film. The method comprises the following steps: firstly, a patient lies on a treatment bed and a treatment area is selected; then, the patient is fixed in the selected area using the thermoplastic film; and finally, the infrared marker is fixed on the thermoplastic film using a cable tie or 3M adhesive.

[0006] Wherein, the thermoplastic film includes head film, head and neck film, pleural film and body film.

[0007] In addition, when the infrared positioning ball is fixed with a cable tie, a parallel fixing method, a triangular fixing method, or a cross fixing method can be adopted.

[0008] The parallel fixing method uses two cable ties to fix the infrared marker base on the thermoplastic film; the cable ties pass through the holes in the thermoplastic film, bypass the infrared marker base and are tied into a knot, and the cable ties passing through the infrared marker base do not intersect and are nearly parallel.

[0009] The triangular fixing method uses three cable ties to fix the infrared marker base on the thermoplastic film; the cable ties pass through the holes on the thermoplastic film, go around the infrared marker base and are tied, and the cable ties form a triangular shape on the infrared marker base.

[0010] The cross fixing method uses two cable ties to fix the infrared marker base on the thermoplastic film; the cable ties pass through the holes in the thermoplastic film, bypass the infrared marker base and are tied into a knot, and the cable ties passing through the infrared marker base intersect to form an X shape.

[0011] In addition, the 3M glue is located on the back of the base and fixed to the corresponding position of the thermoplastic film.

[0012] The infrared marker fixing method can be used in the field of radiotherapy or puncture.

[0013] The present invention also provides a method for fixing the position of an infrared marker on a thermoplastic film. The position of the infrared marker is different for different parts, and six infrared positioning balls are fixed for each part.

[0014] For the head: one infrared marker is located at the upper left of the end of the left brow bone, one infrared marker is located just above the end of the right brow bone, one infrared marker is located at the lower left of the right nose wing, one infrared marker is located above the left mandibular angle, one infrared marker is located above the right mandibular angle, and one infrared marker is located at the tip of the mandibular angle bone;

[0015] For the neck: one infrared marker is located above the left mandibular angle, one infrared marker is located above the right mandibular angle, one infrared marker is located at the tip of the mandible, one infrared marker is located at the joint between the left clavicle and the scapula, one infrared marker is located at the joint between the right clavicle and the scapula, and one infrared marker is located at the junction of the second rib and the sternum;

[0016] For the chest: one infrared marker is located at the center of the left clavicle, one infrared marker is located at the center of the right clavicle, one infrared marker is located at the junction of the second rib and the sternum, one infrared marker is located at the xiphoid process, one infrared marker is located at the outermost end of the ninth rib on the left, and one infrared marker is located at the outermost end of the ninth rib on the right;

[0017] For the abdomen: one infrared marker is located on the left side of the end of the sternum, one infrared marker is located on the outermost end of the ninth rib on the left, one infrared marker is located on the outermost end of the ninth rib on the right, one infrared marker is located at the navel, one infrared marker is located on the left hip wing, and one infrared marker is located on the right hip wing;

[0018] For the hips: one infrared marker is located at the top of the left hipbone, one infrared marker is located at the top of the right hipbone, one infrared marker is located in the middle of the sacrum, one infrared marker is located on the outside of the junction of the left hipbone and femur, one infrared marker is located on the outside of the junction of the right hipbone and femur, and one infrared marker is located on the coccyx.

[0019] The present invention fixes infrared markers by two different methods and can determine the location of the marker fixation, thereby overcoming the shortcomings of existing infrared marker fixation methods. In addition, the present invention has the following significant advantages:

[0020] (1) The method of the present invention can achieve fixation of certain sharp joints through different cable tie fixing methods.

[0021] (2) The method of the present invention can standardize the operator's operation by determining the infrared marker fixed area. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] During the radiation therapy planning phase:

[0029] Step 1: For patients who need IMRT for their lungs, they are first asked to lie supine on the CT bed under the guidance of a technician. A head, neck, and shoulder support is placed under the patient, and the body is kept as straight as possible.

[0030] Step 2: Soak the thermoplastic film in hot water at about 60° to soften it; after softening, place the thermoplastic film on the patient's chest to fix it in shape. After 5-10 minutes, the thermoplastic film will be formed.

[0031] Step 3: Use 3M adhesive to secure six infrared positioning beads. One infrared marker is located at the center of the left clavicle, one infrared marker is located at the center of the right clavicle, one infrared marker is located at the junction of the second rib and the sternum, one infrared marker is located at the xiphoid process, one infrared marker is located at the outermost end of the ninth rib on the left, and one infrared marker is located at the outermost end of the ninth rib on the right.

[0032] Step 4: Perform a CT scan on the patient.

[0033] Step 5: The physicist develops a radiation therapy plan based on the patient's CT scan.
