There is no such thing as which one is better, it only depends on your condition and family condition, which is suitable for that kind of treatment.
Intensity modulated radiation therapy (IMRT) is a type of three-dimensional radiation therapy that requires the dose intensity in the radiation field to be adjusted according to certain requirements, referred to as intensity modulated radiation therapy. It is under the condition that the radiation field at each place is consistent with the shape of the target area, the beam intensity is adjusted according to the three-dimensional shape of the target area and the specific anatomical relationship between the vital organs and the target area, the dose distribution in the single radiation field is not uniform, but the dose distribution in the whole volume of the target area is more uniform than that of three-dimensional conformal therapy. And in terms of reducing the side effects of intensity-modulated radiotherapy.
Strictly speaking, the use of wedge plates and conventional surface bending compensators is also intensity modulation. But here by intensity-modulated radiation therapy we mean a form of three-dimensional conformal radiation therapy that uses a computer-assisted optimization procedure not to acquire nonuniform intensity distributions within individual radiation fields for some defined clinical purpose. It is in this sense that intensity-modulated radiation therapy will be described below.
Indications
(1)? Neurological tumors including gliomas, pituitary tumors, meningiomas, brain metastases, germ cell tumors, medulloblastomas, ventricular meningiomas, pineal gland, chordomas, intracranial lymphomas, brain stem tumors, spinal cord tumors.
(2)? Head and neck tumors? Including nasopharyngeal cancer, laryngeal cancer, maxillary sinus cancer, oral cavity cancer and middle ear cancer.
(3) Thoracic tumors Including lung cancer, esophageal cancer, mediastinal tumor and breast cancer.
(4)? Abdominal tumors? Including pancreatic cancer, liver cancer, bile duct cancer, intestinal cancer, etc.
(5) Tumors of the urinary and reproductive systems, including prostate cancer, renal cancer, and pelvic tumors, etc.
(6) Bone tumors, including osteosarcoma, osteochondrosarcoma, and fibrosarcoma, etc.
(7) Other tumors, including angiomas, malignant granulomas, and other tumors. Hemangioma, malignant granuloma, etc.
Tomo (treatment system)
Tomo, a spiral tomotherapy system, is a combination of IMRT (intensity-modulated conformal radiotherapy), IGRT (image-guided intensity-modulated conformal radiotherapy), and DGRT (dose-guided intensity-modulated conformal radiotherapy), and its original design perfectly combines a linear gas pedal and a helical CT, which breaks through the many limitations of the traditional gas pedal, and provides 360-degree focused tomotherapy under the guidance of the CT. With 360-degree focused tomography irradiation of tumors under the guidance of CT, patients with malignant tumors can be treated with high efficiency and precision.
Advantages
1. Precise irradiation--Special design, highest precision
2. Obvious therapeutic effect--Localized control of the survival of a significant increase
3. --Multiple foci can be completed at one time
4. Wide application - all kinds of tumors can be selected
5. Cost-effective - reduce complications, reduce Total cost
