Embodiment 1

[0033] like Figure 1-3 As shown, a method for determining the X-ray imaging dose according to the thickness value comprises the following steps,

[0034] Step S1: The body shape measurement system accurately measures the body shape thickness measurement value of the patient to be photographed in real time by obtaining the image depth information, and transmits the measurement value to the processor that stores the EI standard range table inside;

[0035] Step S2: The processor looks up the exposure parameters required by the X-ray generator corresponding to the measured value of the patient's body shape thickness in the EI standard range table, and transmits the exposure parameters to the X-ray generator;

[0036] Step S3: The X-ray generator receives the exposure parameters, emits the working tube voltage kvp and the working current product mA·s specified by the exposure parameters, and emits X-rays corresponding to the radiation quality within the specified time;

Embodiment 2

[0040] like Figure 1-2 As shown, as a preferred solution, the body shape measurement system is any one of a visible light measurement system, a near-visible light measurement system or an ultrasonic measurement system. When performing body shape measurement, it is mainly to measure the thickness of specific parts of the patient, which can usually be completed by using the above-mentioned prior body shape measuring device. As a measurement system with high measurement accuracy, the binocular in the visible light rangefinder can be used The camera range finder is used for measurement, including the left camera, the right camera and the rotating mechanism that drives the left camera and the right camera to rotate. After the images taken by the left camera and the right camera are matched and corrected, the same point about the patient's body parts in the left and right images A one-to-one correspondence is obtained to obtain a depth image composed of the distance between the bod...

Embodiment 3

[0045] like image 3 As shown, as a preferred solution, the EI standard range table is established based on the standard radiation quality RQA5 of a specific image chain system and a large amount of clinical data of a specific image chain system, including one-to-one corresponding body part names, body shape thickness values, and working tubes. Voltage value and working current product value.

[0046] Among them, the standard radiation quality RQA5 is the radiation quality of the phantom based on the aluminum additional filter plate, which is used to describe the laying field from the exit surface of the simulated patient, which is clearly quoted in the YY / T 0590.1-2005 industry standard; industry standard YY / T 0590.1-2005 specifies in detail how to adjust the X-ray tube voltage to the required half-valence layer within a given limit to obtain the radiation quality, that is, the corresponding X-ray tube operating voltage and operating current product In addition to the above-...

Abstract

The invention belongs to the technical field of X-ray imaging, and discloses a method for determining the X-ray imaging dosage according to a thickness value. The method comprises the following stepsthat S1, a body type measurement system acquires a body type thickness measurement value of a patient, and transmits the measurement value to a processor; S2, the processor looks up an exposure parameter needed by an X-ray generator corresponding to the body type thickness measurement value of the patient in an EI standard range table, and transmits the exposure parameter to the X-ray generator; S3, the X-ray generator sends out X-rays with the corresponding radiation quality within the specified time; and S4, a flat panel detector receives the X-rays with the suitable radiation quality, and then the clear and accurate imaging is realized. According to the method, through the in-depth ranging technology, the body type thickness data of the patient is acquired, the corresponding exposure parameter is acquired through the 'E1 standard range table', and the X-ray generator is guided to emit the X-rays with the corresponding radiation quality. The invention provides the method which can automatically and accurately acquire the radiation quality of the X-rays needed by the patient to be subjected to shooting at low cost in real time.

Description

technical field [0001] The invention belongs to the technical field of X-ray imaging, and in particular relates to a method for determining X-ray imaging dose according to a thickness value. Background technique [0002] X-ray is a kind of ray, which is what we often call X-ray, which is a kind of energetic electromagnetic wave or radiation. X-rays occur when fast-moving electrons strike any form of matter. X-rays are penetrating and have different penetrating powers for substances of different densities. In medicine, X-rays are used to project images of the human body to assist diagnosis; or to irradiate lesions for treatment. [0003] There has been a long-standing need to accurately obtain the X-ray radiation quality required by the patient to be photographed. The X-ray radiation quality is mainly reflected in the X-ray tube, the working tube voltage kvp of the X-ray source, and the working current product mA· s, the former determines the energy level of the X-ray emit...
