Problems solved by technology

Using this method, the doctor has to switch between the SPECT scanning interface and the CT scanning interface multiple times, which increases the workload, and it takes a certain amount of time to determine the lesion and the bed location.

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] After the image is obtained by SPECT scanning, the present invention uses the scanned image of SPECT to display it on the scanning interface of CT, and uses it as the positioning image of CT scanning, so that doctors can easily arrange CT according to the positioning image when performing CT scanning operations. The scan range of the scan, such as figure 2 As shown, the steps are as follows:

[0031] Step 201, on the SPECT side, select a pair of SPECT images corresponding to the patient from the image database, and transmit the identification of the image to the CT side.

[0032] In step 202, the CT side fills the identifier of the received SPECT image into the scan item of the scan protocol selected by the CT side, and associates the scan item with the SPECT image.

[0033] Step 203, the CT side reads the SPECT image from t...

Abstract

The invention discloses an automatic generation method of CT scan positioning images in a SPECT-CT system, which relates to a fusion technology of SPECT image and CT image. The invention is used for automatically obtaining CT scan positioning images according to SPECT images, which comprises the following steps: first, a SPECT image of a sufferer is selected from an image database at the side of the SPECT and a mark of the SPECT image is sent to the CT side; the CT side fills the received marking of the SPECT image in the scan option of an optional scan protocol of the CT side, the scan option is associated with the SPECT image; the SPECT image is read from the image data base by the CT side according to the marking of the SPECT image and showed in a localization frame as the CT scan positioning image. Adopting the automation generation method of the invention can save scanning time, reduce scanning dose and improve the interfacial amicability level and workability.

Description

technical field [0001] The present invention relates to the fusion technology of SPECT (single photon emission computed tomography, single photon emission computed tomography) image and CT (Computer Tomography, X-ray computer computed tomography) image, specifically, relate to the CT in SPECT-CT system Acquisition technology of scout images of scanned images. Background technique [0002] Combined with CT technology, SPECT can use X-rays to perform image attenuation correction, and integrate anatomical images into functional images on the same machine, which has made a big leap in the quality of nuclear medicine images and the amount of diagnostic information. [0003] In the previous SPECT-CT system, the lesion was scanned with SPECT first, and then the scanning range of SPECT was informed to CT for two scans. Then use relevant software to fuse the image obtained by SPECT scan and the image obtained by CT scan to obtain an image that has both the advantages of SPECT and CT...
