How long is a course of spiral radiotherapy?

The concept of spiral tomotherapy is relatively new, and the literature is relatively small. Therefore, the way of division is different for each family. The traditional ** program is usually 6-7 weeks. Irradiation 5 days a week with 2 days of rest.

First of all, as far as radiotherapy is concerned, unlike chemotherapy, it takes several courses of treatment, generally the best chance of the same lesion is once, the length of time is related to the segmentation method, the number of times, and the type of disease, such as nasopharyngeal cancer, the number of times will be more, because considering the problem of side effects, it will be in 2 months, hypofractionated early lung cancer, the number of times is very small, and the problem will be solved within 2 weeks.

Spiral tomotherapy is also called TOMO radiation system, also known as TOMO knife, TOM knife, Air Force General Hospital --- the military tumor radiotherapy center has been carried out well, many difficult tumors have been solved through TOMO, of course, there is no need to do TOMO, you can do gamma knife, accelerator, is also a good choice, TOMO is a perfect combination of linear accelerator and spiral CT scanner, is a set of 3D-CRT, IMRT, IGRT, DGRT, The disadvantage of ART function as one of the modern radiological equipment is that the cost is high, and there are many advantages, such as small size, good conformability, high efficiency, etc., and has the following advantages:

1.Like spiral CT scanning, the TOMO** method performs 360-degree rotational focused irradiation around the tumor layer by layer, which further improves the uniformity of tumor irradiation dose and dose distribution, and better protects the normal tissues around the tumor.

2.Through the CT scan before radiotherapy, the positioning CT is proportioned, the positioning error is automatically adjusted, and the accuracy of the positioning is improved, and at the same time, the changes of tumors and normal tissues can be observed at any time during the radiotherapy process, and the ** plan can be quickly modified and adjusted for adaptive radiotherapy.

3 **Wide range, TOMO can be as long as 160cm in a single tumor scan, and the cross-section (diameter) can be up to 60cm in a single time. In the range of 60cm (diameter) and 160cm (length), the most accurate intensity modulation can be achieved**, while the traditional accelerator can usually only **40cm at a time, therefore, in addition to the precision radiotherapy of all parts of the body, TOMO is currently the only radiotherapy equipment that can complete the whole central irradiation, whole bone marrow irradiation and multiple targets at the same time.

The damage to brain tissue is still considerable, so that it can have a better effect on cancer.

It's still more difficult to **.

Generally, cancer is almost a lifelong disease, which is difficult and easy, and it is best to combine some drugs to consolidate it after radiotherapy.

The best in this regard is the five liquids.

Spiral tomotherapy (tomotherapy) has incomparable advantages in nasopharyngeal cancer, nasopharyngeal cancer, lung cancer, pleural mesothelioma, esophageal cancer, brain tumor, breast cancer, prostate cancer, systemic multiple metastases and total spinal cord irradiation, and is suitable for tumors in all parts of the body.

Hello, you can consult with Professor Ai Tingyi, vice chairman of the Radiation Oncology Committee of the Chinese Medical Association, his department has the equipment you mentioned, but it is usually called: TOMO, and it is also the best department in China. You can also go to his **:

The Army's Radiation Oncology Center, take a look, there are detailed descriptions of various diseases, and there are also consultation numbers.

Radiation is one of the most important and effective means of malignant tumors today, with a wide range of indications and advantages. Currently, more than 70% of cancer patients require radiation**. WHO (World Health Organization) announced in 1998 that 45% of malignant tumors can be cured, of which 22% are surgical, 18% are radiation, and 5% are chemical.

The innovative intensity-modulated tomographic (IMD**) method combined with traditional CT imaging technology is of great significance for precise radiotherapy of tumors. The introduction of Tom Knife is a major decision made by the hospital based on the development of oncology and regional medical resource planning. It is believed that the introduction of this equipment is of great significance to improve the level of oncology in the hospital, enhance the level and influence of discipline construction, and better serve the officers and soldiers of the army and the people in the station.

The director of the Guangzhou General Hospital of the Guangzhou Military Region said so.

Tomotherapy, an innovative, flexible and integrated radiotherapy system, is an advanced radiotherapy device that can be used for a wide range of cancers. Tomotherapy combines and integrates traditional CT imaging technology and spiral tomography intensity-modulated conformal therapy, which can accurately and rapidly irradiate a variety of complex tumors while greatly reducing the dose of surrounding normal tissues.

Spiral tomotherapy is a cancer radiation method based on the TOMO equipment of the spiral tomography system, which is the most advanced tumor radiation technology today.
