A kind of high-pressure injector in imaging examination and its information integration method

Abstract

The invention discloses a high-pressure injector in image inspection and an information integration method thereof. The high-pressure injector in the present invention includes a module capable of information interaction and processing with the RIS / PACS system. After the high pressure injector receives the message from the RIS / PACS system, it initializes the injector, and matches and extracts the injection protocol. After the inspection is completed, a graphical injection information report is formed and sent to the RIS / PACS system by means of DICOM Storage. The invention realizes the automatic cooperative work of the high-pressure injector in the image inspection process to the greatest extent in the background by means of message driving and data interaction, effectively reduces the workload of inspection technicians, reduces errors and improves work efficiency. At the same time, the archive of contrast agent injection records is realized, and an important part of radiological image quality control is added to standardize the imaging inspection process and improve the inspection quality.

Description

technical field [0001] The invention belongs to the technical field of hospital imaging examination (CT, MR, DSA), and particularly relates to a high-pressure injector and an information integration method thereof in imaging examination. Background technique [0002] With the development of medical imaging technology, the application scope of various medical imaging equipment is becoming wider and wider, and the application hospitals are becoming more and more popular. At the same time, the workload of the hospital medical technology department (radiology department) is increasing. In the process of CT, MR, DSA and other examinations, it is often necessary to inject contrast agents into patients to improve the detection rate of lesions, including tumors, and to improve the qualitative diagnosis of lesions. [0003] As a device that can control the injection rate and dose of contrast media, high-pressure syringes have been used in radiology popularization and application in h...

AI Technical Summary

Problems solved by technology

[0004] In fact, the technology described in literature [1][2] has not been widely used in actual inspections. The reason is that there are many defects: the data interface coupling between the computed tomography equipment and the syringe in literature [1] is too tight , in the sub-stages of start-up (preparation), inspection (scan execution and injection execution), single device failure (interruption of the other party), not only involves data exchange, but also affects the actions of the other party

Problems caused by this: (1) Manufacturers of imaging equipment and syringes need to define detailed data exchange private protocols, and carry out a lot of transformation and development (Note: No standardized interface has been reached so far, and there is only one syringe manufacturer in the market with a certain type of syringe and a certain The CT of the equipment manufacturer has carried out private interface docking); (2) The imaging equipment is highly tied to the syringe, and the inspection technician needs to untie the syringe during ordinary scanning (during normal scanning), which increases the workload instead

The resulting problems: (1) allow the inspection technician to manipulate the syringe, making the console more complicated

If it is a switchable interface (document [2] Figure 15), instead, the inspector frequently switches, which increases the complexity of the operation; if it is an integrated interface (document [2] Figure 16), the realization of the function requires two manufacturers With close cooperation and extensive transformation, inspection technicians must master more action instructions; (2) the combination of operating parameters also makes the imaging equipment and syringes too tightly coupled, and the difficulty of technical realization increases sharply (Note: no such "common control console" has appeared so far. ")

[0005] The above-mentioned existing technologies all involve a large number of transformations by manufacturers of imaging equipment and syringes, resulting in the problem of coordinated control of imaging equipment and syringes not being well solved in actual work. At the same time, there are still many practical problems in the current imaging inspection of high-pressure syringes :

The inconvenient input of the touch screen display of the high-pressure injector itself, and the multi-line operation between the inspection equipment and the high-pressure injector that the inspection technician needs to make the above situation worse, resulting in greater work pressure for the inspection technician. A slight negligence may cause Major errors in confirming patient information

[0008] 2. Contrast medium injection protocol issues

Since the control operation of such parameters is directly related to the patient's examination site and examination items, if the examination technician needs to manually operate and adjust the injection plan every time, it is very easy to make mistakes and affect the final imaging quality

[0010] 3. The preservation of contrast agent injection records

[0012] 4. Image quality control issues related to contrast medium injection

Due to the lack of detailed records of relevant contrast agent injection information at the time of inspection, it is impossible to determine or rule out whether there is a difference in contrast agent injection or an abnormality during the injection process when evaluating the image quality afterwards, especially the image quality related to the patient's image enhancement effect Effects of Conditions on Image Quality
