Pathological diagnosis is the gold standard for diagnosis

Check the patient's application form and the information on the wristband (name, gender, age, medical record number). After confirming that the identity is correct, arrange a treatment time to introduce the importance of position fixation to the patient and their family members, and instruct the patient to breathe slowly and remove metal objects from the body. (Necklace, pendant), wearing light clothing, no buttons or other accessories

Evaluate the patient's physical condition: Based on the information on the application form and the patient's mental state, for patients undergoing enhanced scanning, ask whether they have a history of allergies, severe diabetes, hyperthyroidism, abnormal renal function, etc., strictly control contraindications, and ask the patient to sign a special inspection notification Consent form. Critically ill patients and patients who need enhanced scanning must be accompanied by a competent physician. Drugs can be used for uncooperative patients (young children).

If there is an unhealed surgical incision within the patient's positioning range, it is generally recommended to position the patient after the wound has healed to avoid wound infection caused by affixing position markers and marking machines.

Body frame fixators are usually made of carbon fiber materials to ensure high penetration of radiotherapy rays and reduce the impact on dose

Foam glue uses two chemical substances to mix to produce a chemical reaction. It foams and expands. After cooling, it is shaped and solidified. The human body surface contour is used for radiotherapy position fixation. It is different from other fixation methods in that it is an active shaping fixation. Way

Prospective 4D-CT scan: the respiratory phase is unified for each scan and needs to be coordinated with respiratory gated radiotherapy

Retrospective 4D-CT scan: collect images of all respiratory realities, observe the range of motion of the target area, and formulate individualized PTV for targeted radiotherapy (more applications)

Before the patient's first treatment and between the CT simulation positioning, the patient's position is calibrated (in addition to making the heat shrink film, the process is the same as the position fixation and simulation implementation process)
