The preset rule mentioned here may specifically be: firstly, searching a characteristic information group with the same examination part as the examination part to be contrasted of the current patient in the database, and then searching a characteristic information group with a difference value smaller than a preset threshold value with other characteristic information values of the current patient in the searched characteristic information group to obtain a matched characteristic information group and an injection scheme thereof.
Such as:
currently, the height of a patient is 177cm, the height of the patient is male, the height of the patient is 36 years old, the examination part is a brain, in the process of matching the injection scheme, the injection scheme of which the examination part is not the brain in the database is firstly excluded, the injection scheme of which the female part is female is excluded, then for example, the age value is matched with the floating value of 1 year old, the height is matched with the floating value of 2cm, the injection scheme of which the age is less than 35 years old or more than 37 years old is excluded, and the injection scheme of which the height is less than 175cm or more than 179cm is excluded, so that the rest matching injection scheme is obtained. Except for the case where the remaining matched injection protocol is exactly one, the following two more cases occur:
the first case is matching to more than one injection protocol, and then one of the injection protocols may be selected according to a set strategy, for example, randomly, or (in a certain weight calculation manner), a closer injection party is selected from the injection protocols, and the characteristic information set includes two kinds of characteristic information, namely height (cm) and age (month), besides the examination location (and sex), the weight values of the two are 0.8 and 0.2, for example, the first injection protocol is related to height 175cm, male, age 35.5, the examination location is a characteristic information set of the brain, and the difference between the characteristic information set and the characteristic information of the current patient is 0.8 × 2+0.2 × 6 ═ 2.8; the second injection scheme is related to the height of 178cm, male, age 37, and the examination part is a characteristic information group of the brain, and the difference between the characteristic information group and the characteristic information of the current patient is 0.8 × 1+0.2 × 12-3.2; in contrast, the difference of the first is small, and the first injection protocol may be preferred.
In the second case, there is no matching injection protocol, i.e. the injection protocols in the database are all excluded during the above exclusion process, in which case a prompt, such as a voice prompt and/or a light prompt, may be issued that requires manual establishment of an adapted injection parameter model; after the adaptive injection parameter model is manually established, an injection scheme is generated by combining the characteristic information of the current patient and is additionally written into the database, so that the database content is more and more abundant.
In this embodiment, the system does not include a manual central control device for inputting injection parameters corresponding to the patient into the injector device, i.e. the injection parameters do not need to be manually input item by item, for example, the following technical solutions can be implemented: the patient sees a doctor, a doctor develops an examination order for pulmonary radiography in the electronic medical record of the patient, and the patient obtains a list of bar codes after paying by the examination order, wherein the bar codes comprise part or all information of the electronic medical record of the patient; the patient holds the sheet and goes to a control room outside the examination room, and a technician or nurse in the control room reads the sheet by using the code scanner, in a way that the reading content is displayed on a display connected with the code scanner and then is manually input into the control host, such as the working parameters (frequency, power, radiation dose and scanning speed) of the scanning device and the characteristic information of the patient, such as the examination part to be scanned and also any one or more of the height, the weight, the sex, the age, the blood pressure, the blood sugar and the blood viscosity of the patient;
The semi-manual input mode can also be adopted as follows: and performing data processing on the content read by the code scanner, for example, extracting the content required to be input into the control host, automatically inputting the content into the control host, and then inputting the rest information which cannot be acquired through the code scanner into the control host so as to further reduce the workload of a technician or a nurse for inputting parameters on the control host.
In another embodiment of the present invention, another medical contrast imaging system is provided, which is different from the previous embodiment in that a processor of a control system of an injector of this embodiment is connected with a data reading interface, the data reading interface is used for being electrically connected with an external removable storage medium, priorities of the external removable storage medium and a database are not specifically limited, taking the case that the priority of the external removable storage medium is higher than that of the database as an example, as a working process referring to fig. 3, firstly, whether the external removable storage medium is plugged in the data reading interface is judged, if yes, the processor retrieves an injection scheme matching with characteristic information of a current patient from the external removable storage medium according to a preset rule, and if the retrieval is successful, the injector injects the current patient according to injection parameters of an injection parameter model in the retrieved injection scheme, and (6) ending. The above may be directed to a control system in which the injection protocol is not written to the database, using only an extrapolated removable storage medium, such as a usb-disk or SD-card, etc., as a carrier for storing the injection protocol.
If the movable storage medium extrapolated from the interface is not detected, or the injection scheme cannot be matched in the extrapolated movable storage medium, the processor calls the injection scheme matched with the characteristic information of the current patient from the database according to the acquired characteristic information of the patient and a preset rule, and then the injector injects the current patient according to the injection parameters of the injection parameter model in the called injection scheme.
If the priority of the database is higher than that of the external removable storage medium, otherwise, the description is omitted.
For the above two different embodiments, after the injection of the contrast medium and the scan imaging are completed, it may be determined whether the imaging result of the actual contrast medium is qualified, and if the imaging result is not qualified, the currently executed injection parameter model is corrected in the database, for example, if the imaging is not clear enough, the dose value in the currently used injection parameter model may be attempted to be increased.
