Real-time tumor site monitoring system and real-time tumor site monitoring method

Abstract

The invention discloses a real-time tumor site monitoring system and a real-time tumor site monitoring method. The real-time tumor site monitoring system comprises a pneumotachometer, a machine head MLC driving mechanism and a PLC (programmable logic controller). The pneumotachometer comprises a pneumotachometer body (1), a trumpet tube (4) and a gas outlet tube (5) are arranged on the left and right sides of the pneumotachometer body (1), a flowmeter (6) is arranged on the gas outlet tube (5), a first open-close door (7) is hinged to the end of the gas outlet tube (5), the machine head MLC driving mechanism comprises two longitudinal guide rails (10), two sliders (11) sliding along the longitudinal guide rails (10) are arranged on the longitudinal guide rails (10), guide sleeves (12) are arranged on the sliders (11), two horizontal guide rails (17) are arranged between the two opposite guide sleeves (12), and an MLC (13) is arranged between the two horizontal guide rails (17). The real-time tumor site monitoring system and the real-time tumor site monitoring method have the advantages that tumor movement caused by breathing movement can be tracked more precisely and favorable conditions can be offered for subsequent tumor treatment, and the method is simple.

Description

technical field [0001] The invention relates to the technical field of lung tumor tracking, in particular to a tumor location real-time monitoring system and a monitoring method thereof. Background technique [0002] At present, the respiratory gating system is mainly controlled by foreign manufacturers, mainly including the infrared binocular respiratory gating system from GE, the abdominal pressure-sensitive respiratory gating system from Philips, and an active breathing system called ABC. The gating system and Elekta's predictive respiratory gating system, in simple terms, GE uses two infrared cameras to sense the body surface driven by the breathing movement of the module placed on the patient's body surface (mainly the chest and abdomen). Movement, and then through a series of algorithms to simulate the image movement caused by breathing movement. [0003] The biggest difference between Philips' abdominal pressure-sensitive respiratory gating system and GE's is the fro...

Problems solved by technology

There is also Elekta's 4D system, which is also used in accelerator therapy. The principle is to improve the beam output of accelerator rays through computer algorithms. The disadvantage is that it does not measure, but is an implementation of calculation through algorithms.
