What is TOMO knife medical device

TOMO knife is the world's only radiation therapy device that uses spiral CT scanning to treat cancer, i.e. tomotherapy, which can treat tumors up to 4,000px at a time like spiral CT scanning, and can treat cross-sections up to 1,500px in diameter, and can achieve the most precise intensity modulation treatment within such a range of 1,500px in diameter x 4,000px in length. In this 1500px (diameter) x 4000px (length) area, the most accurate intensity tuning treatment can be realized, whereas conventional gas pedals can only treat an area of up to 1000px at a time. Therefore, the TOMO knife is the only radiotherapy equipment that can perform total central irradiation, total bone marrow irradiation and simultaneous treatment of multiple target areas at one time, in addition to precise radiotherapy for all parts of the body; the TOMO knife has advantages in the radiotherapy of nasopharyngeal cancer, recurrent nasopharyngeal carcinoma, lung cancer, pleural mesothelioma, esophageal cancer, brain tumors, breast cancer, prostate cancer, multiple metastatic tumors in the whole body, and total spinal irradiation.

The advantages include:

1. precise stereotactic positioning means;

2. multi-path irradiation mode, which greatly exceeds the joule-to-picone ratio (the ratio of the dose received by diseased tissues to healthy tissues per unit volume) of the conventional radiotherapy;

3. from the point of view of clinical radiological dosimetry, stereotactic radiotherapy has an accurate dose irradiation on the tumor tissues and gives the tumor tissues a greater killing, and at the same time, the tumor tissues can be killed. From the perspective of clinical radiation dosimetry, stereotactic radiotherapy has accurate dose irradiation to tumor tissues, giving greater killing and wounding of tumor tissues, and at the same time significantly reducing the irradiation to the surrounding normal tissues; and through the computerized treatment planning system, it can carry out one-time large-dose lethal irradiation of tumor tissues, and "resect" tumors like surgery, so it is called the "Radiotherapy knife". It includes Gamma Knife, Radio Wave Knife, EDGE, and Proton Heavy Ion.
