Problems solved by technology

[0004] Therefore, the present invention aims to provide a method for measuring bone density through DR shooting and a DR shooting device to solve the problem that in the prior art, jaw bone density images cannot be directly obtained, and it is necessary to rely on dental clinicians to observe the patient's preoperative images with the naked eye. For dental films, the bone density of the jaw is graded and judged by the sparseness of the spatial arrangement of the bone trabeculae. Due to the lack of accurate bone density values ​​as an accurate reference, it is easy to cause large errors and affect the success rate of surgery.

Embodiment 1

[0085] A method for measuring bone density by DR shooting, comprising the following steps:

[0086] S1, sending X-rays towards the scanned body to obtain an intraoral film; in step S1, including: a ray source; during the process of obtaining the intraoral film, the ray source scans twice to obtain a set of high-energy attenuation data and a set of low-energy attenuation data; the ray source is carried out under high-voltage exposure conditions during one scanning process, and the ray source sends high-energy X-rays to the scanned body to obtain a set of high-energy attenuation data; The ray source is performed under low-voltage exposure conditions during another scanning process, and the ray source sends low-energy X-rays to the scanned body to obtain a set of low-energy attenuation data;

[0087] S2. Obtain high-energy X-rays and low-energy X-rays passing through the scanned body, respectively;

[0088] S3. The processing unit separately acquires high-energy X-rays and low-e...

Embodiment 2

[0107] A method for measuring bone density by DR shooting, comprising the following steps:

[0108] S1, sending X-rays toward the scanned body, so as to obtain an intraoral film; in step S1, including: a radiation source; the radiation source scans once, and sends high-energy X-rays toward the scanned body; and, in step S1, Attenuating part of the high-energy X-rays through a filtering principle, so that the radiation source sends low-energy X-rays toward the scanned body at the same time;

[0109] S2. The ray receiving mechanism receives high-energy X-rays and low-energy X-rays passing through the scanned body;

[0110] S3. The processing unit separately acquires high-energy X-rays and low-energy X-rays passing through the scanned body, and uses an image reconstruction algorithm to obtain a bone tissue density image.

Embodiment 3

[0112] A DR shooting device, such as figure 1 and figure 2 As shown, the DR shooting device is an intraoral dental film machine,

[0113] It includes:

Abstract

The invention discloses a method for measuring bone mineral density through DR shooting and DR shooting equipment, wherein the method for measuring bone mineral density through DR shooting comprises the following steps: S1, transmitting X-rays to a scanned object, to obtain an intraoral film; S2, respectively acquiring high-energy X-rays and low-energy X-rays which penetrate through the scanned object; and S3, enabling the processing unit to obtain high-energy X-rays and low-energy X-rays penetrating through the scanned body, and obtaining a density image of a bone tissue through an image reconstruction algorithm. According to the method, the density image of the bone tissue can be obtained, so that the problems that in the prior art, an oral clinician needs to observe a dental film shot before an operation of a patient through naked eyes, grading judgment of jaw bone density is carried out through the sparse degree of spatial arrangement of bone trabecula, and an accurate bone density numerical value is lacked as an accurate reference, large errors are easily caused, and the success rate of the operation is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and mainly relates to a method for measuring bone density through DR shooting and DR shooting equipment. Background technique [0002] Dental implant is by far the most ideal way to restore missing teeth, and its implementation process is also quite complicated. Before dental implantation, patients first need to perform radiographic examinations on the pre-implantation site for various evaluations. Among them, the bone density assessment of the implantation area is How to measure the bone density of the jaw accurately, effectively and practically is the key step to achieve the success of dental implant, which plays a very important guiding role in the formulation of implant and periodontal surgery and the judgment of prognosis. In addition, oral bone loss is an important factor affecting the retention of teeth and the success of denture restoration. studied by measuring the bone densit...
