Medical Oral and Maxillofacial Cone Beam Tomography (CBCT)X-ray Radiation Source Calibration Device

Medical Oral and Maxillofacial Cone Beam Tomography (CBCT)X-ray Radiation Source Calibration Device

Background Introduction

Medical Oral and Maxillofacial Cone Beam Computed Tomography (CBCT)X-ray radiation source According to 

the different absorption coefficients of X-rays from different tissues of the human body, using highly sensitive 

photon detection technology, the detector receives the X-ray attenuation value of the scanning plane and converts

 it into current, and then it is processed by the computer system into pixel matrices of different gray levels through

 analog-to-digital and digital-to-analog converters and displayed on the computer screen, thus, the detection results

 are represented by a series of accurate and detailed images of the tissue level, and the three-dimensional image and 

pathological changes of the tissue structure can be obtained, so as to achieve the purpose of auxiliary diagnosis.

The X-ray radiation source calibration device of medical oral and maxillofacial cone beam tomography (CBCT) is

 mainly composed of two parts: [Dose and area product (DAP) measurement system] and [Oral CBCT test phantom]. 

The calibration device adopts integrated and wireless design and cooperates with special data processing system to 

measure medical image diagnostic X-ray equipment and dose area value (DAP), the dose-area product, spatial 

resolution, uniformity, contrast noise index and other parameters of X-ray radiation source of medical oral and 

maxillofacial cone beam computed tomography (CBCT) can be tested and calibrated, which is in line with 

the "JJG1198-2023 medical oral and maxillofacial cone beam computed tomography (CBCT) X-ray radiation source". 

Product Introduction

Dose and Dose and Area Product (DAP) Measurement System Area Product (DAP) Measurement System

Dose and area product (DAP) measurement system is used to measure dose and area product (DAP), dose and area 

product rate (DAPrate) and irradiation time S. It is an accessory to radiological and fluoroscopic diagnostic X-ray 

equipment.applications, it is very suitable for monitoring whether the dose received by the patient meets the 

requirements of local regulations. Bluetooth Upgradeversion offers the advantages of a wireless solution and is more

 suitable for portable and mobile X-ray equipment.

Oral CBCT test phantom

oral CBCT test phantom is composed of plexiglass (PMMA) and polyvinyl chloride (PVC). The phantom is 16cm in 

diameter and consists of 4 modules. The main test parameters are: Nyquist frequency (NF), contrast, noise and 

contrast-to-noise ratio (CNR), uniformity, modulation transfer function (MTF) at 10%-50%, artifacts, acceptance 

indicators, phantom position accuracy, geometric testing, etc.

Product Features

data can be transmitted wirelessly between the display unit and the DAP dosimeter

Unique QA/QC Software

data can be transmitted directly to X-ray equipment via Bluetooth

automatically evaluates and displays all collected parameters

No need to install cables, more economical, convenient, and save time

can automatically calculate the quality factor (system index)

Powered by rechargeable lithium battery or plug-in power supply

measured dose values and image quality
