Embodiment Construction

[0020] The implementation of the extended skeleton camera of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Skeletal imaging machine is a kind of nuclear medicine imaging examination of whole body bones. The difference between it and X-ray imaging examination of local bones is that radioactive drugs (bone imaging agent) should be injected before the examination. After 2 to 3 hours, radioactivity detection equipment (such as gamma camera, ECT) is used to detect the distribution of radioactivity in the bones of the whole body. If the absorption of radioactivity in a certain bone increases or decreases abnormally, there is abnormal concentration or sparseness of radioactivity. Abnormal bone radioabsorption in bone scan is the reflection of abnormal bone metabolism. Therefore, bone scans can detect lesions earlier than X-ray examinations, as early as 3 to 6 months.

[0022] Bone scans can detect bone metastatic tumors...

Abstract

The invention relates an extending type skeleton fibrograph which comprises a radiography part and an effectiveness distinguishing device. The radiography part comprises an enhancing screen, a CCD sensing device, an image collecting card and a field display screen. The enhancing screen is arranged on the upper side of a detected patient and used for receiving ray signals permeating the detected patient. In the radiography part, the CCD sensing device is connected with the enhancing screen and used for converting the ray signals enhanced by the enhancing screen into radiography image signals. In the radiography part, the image collecting card is connected with the CCD sensing device and the field display screen and used for collecting the radiography image signals and sending the collectedradiography image signals to the field display screen. The effectiveness distinguishing device is connected with a pixel point authenticating device and used for receiving a plurality of skeleton pixel points in a subsequent processed image and sending out a signal effectiveness command when the number of the skeleton pixel points exceeds the limit. Through the extending type skeleton fibrograph,the abuse of the low-quality radiography image is avoided.

Description

technical field [0001] The invention relates to the field of skeletal cameras, in particular to an extended skeletal camera. Background technique [0002] According to the different degrees of absorption of X-rays by bones and tissues of different densities, the skeletal camera inputs the received digital signal with human body information into the computer for analysis to obtain the result of bone density. This type of equipment has an X-ray source, a detector, an information analysis and display system, and possibly a patient support device. Contents of the invention [0003] In order to solve the technical problem of lack of judging mechanism for the validity of the imaging signal of the current skeleton camera, the present invention provides an extended skeleton camera, which uses the wireless communication method based on the GPRS communication link to obtain the latest standard test chart, Analyze the linear distortion degree of the image after linear distortion pro...
