Abstract

According to the present invention, there is provided an image data detecting apparatus for X-ray CT comprising a scanning apparatus including an X-ray tube for emitting X-rays while rotating about a patient, a detector for detecting X rays emitted by the X-ray tube and passing through the patient, and a memory unit for storing transmission X-ray data detected by the detector, and a transmitting/receiving unit for transmitting the transmission X-ray data stored in the memory unit together with an identification number for identifying the image data detecting apparatus. The image data detecting apparatus of the present invention can be set solely in an inspection site, thereby making it possible to save the space for inspection.

Claims

1. An X-Ray CT scanner system comprising:

a plurality of image data detecting apparatus, each apparatus having a pre-given, individual identification code to distinguish each image data detecting apparatus from the other image data detecting apparatus; and

an image processor placed separately from and operatively connected to each of the plurality of image data detecting apparatus through a communication medium,

wherein each of the plurality of image data detecting apparatus comprises;

an X-ray generating means for generating X rays toward an object;

an X-ray data acquisition system for detecting the X rays passing through the object and outputting X-ray projection data corresponding to the detected X rays, and

an information transmitting means for transmitting through the communication medium to the image processor the pre-given identification code and information including the X-ray projection data; and

wherein

the image processor comprising;

an inputting means for inputting the identification code and the information transmitted through the communication medium, the inputting means including means for verifying the identification code; and

an image reconstruction means for reconstructing a tomography image based on the X-ray projection data.

2. The X-ray CT scanner system of claim 1 wherein said communication medium includes an electric wave.

3. The X-ray CT scanner system of claim 1 wherein said communication medium includes a telephone line.

4. The X-ray CT scanner system of claim 1 wherein said communication medium includes an information record medium.

5. The X-Ray CT scanner system of claim 1, wherein said information transmitting means comprises:

means for transmitting the pre-given, individual identification code to the image processor through the communication medium;

means for receiving a verifying signal from the image processing means through the communication medium; and

means for transmitting the information including the X-ray projection data acquired by the X-ray data acquisition system to the image processor through the communication medium after the verifying signal is received by the receiving means; and

wherein said verifying means comprises;

means for receiving the pre-given, individual identification code transmitted through the communication medium by the identification code transmitting means;

means for verifying the identification code received by the identification code receiving means; and

means for transmitting to the information transmitting means for the verifying signal through the communication medium after verification of the pre-given, individual identification code of the image data detecting apparatus.
