Problems solved by technology

[0011] However, for the current detection panel, when used in the field of MV-level dose monitoring, due to the limitation of current technological development, the image resolution, signal-to-noise ratio and imaging dose are less effective than KV-level imaging. Detection accuracy is not high enough

Embodiment Construction

[0025] In order to simplify the work of doctors or physicists in the radiation therapy process, apply MV-level X-ray images in dose monitoring, and at the same time meet the accuracy requirements of dose verification, a method of simultaneously detecting point doses in MV-level image detection is proposed. Dose monitoring is achieved.

[0026] Such as figure 1 , figure 2 As shown, the digital image detection device used for rapid real-time point dose detection verification in tumor radiation therapy includes a housing 1 and a digital flat panel detector 2, the digital flat panel detector 2 is packaged in the housing 1, and the digital flat panel detector 2 An ionization chamber detector 3 is arranged in the middle part of the digital flat panel detector 2, and a semiconductor dose probe 4 is respectively arranged at the four corners of the digital flat panel detector 2.

[0027] Based on the digital flat panel detector 2 with point dose detection and verification functions,...

Abstract

The invention relates to a digital image detecting device for measuring detection and verification of point dosage rapidly in real time. The middle region of a digital flat-panel detector is provided with at least one ionization chamber detector or semiconductor detector; the periphery parts of the digital flat-panel detector are respectively provided with at least one semiconductor detector or ionization chamber detector; an MV (millivolt)-level X-ray image is obtained under MV-level energy irradiation by the digital flat-panel detector, the MV-level energy of the point is detected and received by the ionization chamber detectors or the semiconductor detectors, and the detection result of the point dosage of the point are recorded; and comparison is carried out on the acquired detection result of the point dosage and the dosage result of the corresponding point on the dosage image of the digital flat-panel detector, thus the dosage result within the whole field range of the digital flat-panel detector can be obtained rapidly in real time.

Description

technical field [0001] The invention relates to a digital image detection device for rapid real-time point dose detection and verification in tumor radiotherapy, which can detect X-rays and generate digital images for patient position verification; detect MV-level X-rays, obtain digital images, and detect point doses , for dose distribution verification. Background technique [0002] Direct digital radiography (Digital Radiography, referred to as DR), is a new technology of X-ray photography developed in the 1990s. It has notable advantages such as faster imaging speed, more convenient operation, and higher imaging resolution. It is the leading direction of digital radiography technology and has been recognized by clinical institutions and imaging experts all over the world. In recent years, with the increasing maturity of technology and equipment, DR has been rapidly promoted and popularized all over the world, and has gradually become one of the necessary equipment in hos...
