Problems solved by technology

[0004] Therefore, the present invention aims to provide a method for measuring oral bone density and its equipment to solve the problem that the density image of bone tissue cannot be directly obtained in the prior art, and it is necessary to rely on the dental clinician to observe the patient's tooth film with the naked eye, and rely on the reconstruction of the bone density image in the image. The sparseness of the spatial arrangement of the trabeculae is used to assess the bone density of the oral and jaw bones, resulting in poor accuracy of bone density assessment

Embodiment 1

[0069] A method for measuring oral bone density, comprising the steps of:

[0070] S1, sending X-rays towards the object to be scanned; X-rays alternately switch the exposure conditions during the process of emitting beams, so that X-rays form high-energy X-rays under high-pressure exposure conditions to obtain a set of high-energy attenuation data; in addition, make X-rays Form low-energy X-rays under low-pressure exposure conditions to obtain a set of low-energy attenuation data;

[0071] S2, respectively receiving the high-energy X-rays and the low-energy X-rays passing through the scanned body through a detector;

[0072] 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. In the above step S3, the processing unit acquires the CBCT rotation scan projection image, and obtains the bone tissue density image by using an image rec...

Embodiment 2

[0091] A method for measuring oral bone density, comprising the steps of:

[0092] S1, sending high-energy X-rays and low-energy X-rays towards the scanned body;

[0093] S2, respectively receiving the high-energy X-rays and the low-energy X-rays passing through the scanned body through a detector;

[0094] 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. In the above step S3, the processing unit obtains the tomographic projection map of the curved surface, and obtains the density image of the bone tissue by using an image reconstruction algorithm.

Embodiment 3

[0096] A method for measuring oral bone density, comprising the steps of:

[0097] S1, sending high-energy X-rays and low-energy X-rays towards the scanned body;

[0098] S2, respectively receiving the high-energy X-rays and the low-energy X-rays passing through the scanned body through a detector;

[0099] 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. In the above step S3, the processing unit acquires the DR photographed image, and obtains the bone tissue density image by using an image reconstruction algorithm.

Abstract

The invention discloses an oral cavity bone mineral density measuring method and equipment thereof. The oral cavity bone mineral density measuring method comprises the following steps: S1, sending high-energy X-rays and low-energy X-rays to a scanned body; S2, respectively receiving the high-energy X-ray and the low-energy X-ray which penetrate through the scanned body through a detector; and S3, by a processing unit, obtaining the high-energy X-rays and the low-energy X-rays penetrating through the scanned body, and obtaining a density image of the bone tissue through an image reconstruction algorithm. By means of the method, the density image of the bone tissue can be obtained, and therefore the problem that in the prior art, an oral clinician needs to observe a dental film of a patient through naked eyes, oral jaw bone mineral density evaluation is conducted through the sparse degree of spatial arrangement of bone trabecula in a reconstructed image, and consequently the accuracy of bone mineral density evaluation is poor is solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and mainly relates to a method for measuring oral bone density and equipment thereof. Background technique [0002] Dental implants are by far the most ideal way to restore missing teeth, and the implementation process is quite complicated. Before implanting dental implants, patients first need to perform radiographic examinations on the pre-implantation sites to evaluate various aspects, including gum space, alveolar bone hardness, Implantation angle and depth, etc. Among them, the assessment of bone density in the implant area is a key step in the success of dental implants. How to measure the bone density of the jaw accurately, effectively and practically is important for the formulation and prognosis of implant and periodontal surgery. The judgment has a very important guiding role. In addition, oral bone loss is an important factor affecting the retention of teeth and the success ...
