Background

Medical imaging apparatuses such as CT (Computed Tomography) apparatuses, DSA (Digital Subtraction Angiography) apparatuses, and the like all scan a slice of a certain thickness of a part of a scanned object such as a human body by emitting X-ray beams through a bulb to obtain a CT scan image, and thus the bulb is a core component of such medical apparatuses.

For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

The control method for the preheating-free scanning of the bulb tube can be applied to medical equipment for obtaining an image of a detected object in an X-ray scanning mode, and the medical equipment can comprise a CT (computed tomography) device, a PET-CT device, a DSA (digital signal processor) device and the like. Taking a CT apparatus as an example, the tube is a core component of the CT apparatus because the CT apparatus radiates an X-ray beam through the tube to scan a layer of a certain thickness of a certain part of a subject, for example, a human body in general, and obtain a CT scan image.

After the CT apparatus is turned on, in order to prevent the filament from breaking due to sudden scanning in a long-time cooling state, the bulb tube is usually preheated first, and the filament can be paid off and scanned after the preheating is completed. As the preheating process of the bulb tube mainly generates a large dose of X-ray beams in a period of time through the bulb tube, the cathode filament of the bulb tube is heated to a working state. And, after each preheating of the bulb is completed, the bulb of the CT apparatus may have a usable time, for example, 4 hours, and during the usable time, the bulb may perform the payoff scanning directly without preheating. Within the tube availability time, e.g. 4 hours, if the tube has been payed out for a scan, the remaining availability time of the tube will be recalled from the moment of the last payout scan, e.g. the CT device is at 8: 00, completing one-time bulb tube preheating, 10 a.m.: 00, paying off and scanning a patient, and recovering the preheating-free remaining available time of the bulb tube to 4 hours; if the duration of the non-operational state of the bulb of the CT device has reached 4 hours, for example, from 10 a.m.: during the period from 00 to 14:00 pm, the bulb tube of the CT apparatus is always in a non-working state, after 14:00 pm, the remaining preheating-free available time of the bulb tube is already 0, and if the CT apparatus needs to be used for performing the line-releasing scan on the patient, the bulb tube should be preheated again.

Based on the description, the method controls the bulb tube to perform one-time preheating-free pay-off scanning when the bulb tube is in a non-working state and the preheating-free remaining available time of the bulb tube is greater than 0, so that the preheating-free remaining available time of the bulb tube is recovered to the maximum value of the available time of the bulb tube again, the bulb tube preheating process is avoided as much as possible, and the problem that the bulb tube is easy to lose in the existing bulb tube preheating process is solved; meanwhile, the problem that inconvenience is caused to patients and medical staff due to long preheating time of the bulb tube is solved.

The method provided by the present application is described in detail below with reference to specific examples.

Referring to fig. 1, a flowchart of an embodiment of a control method for preheating-free scanning of a bulb according to the present application is shown. The method may comprise the steps of:

step 101: when a preheating-free scanning trigger instruction is detected, acquiring a corresponding preheating-free scanning condition; when a preheating-free scanning trigger instruction is detected, the bulb tube of the medical equipment is in a non-working state, and the preheating-free remaining available time is more than 0.

Taking the CT device as an example, the CT device can display the preheating-free remaining available time of the bulb tube in real time on the main control interface; or, the preheating-free remaining available time of the bulb tube can be reminded at intervals according to the system setting of the CT equipment by the manager.

First, when the bulb of the CT apparatus is in the non-operating state and the remaining free time of the preheating-free operation is greater than 0, a process of detecting a scanning trigger command of the preheating-free operation is described as an example:

in an alternative implementation, after the subject, such as a patient, registers the scanning reservation information, the CT device may detect the scanning reservation information of the patient. At this time, the CT apparatus may output the preheating-free remaining available time of the bulb, for example, remind the output of the preheating-free remaining available time of the bulb by a sound, or display the preheating-free remaining available time of the bulb on the main control interface.

Medical personnel can judge whether the bulb is enough to support the unwrapping wire scanning to the disease at present through the exempting from of bulb and preheating remaining available time to and the scanning reservation information of disease. For example, if the preheating-free remaining available time of the bulb only remains 3 minutes, and the medical staff judges that the setting time of the patient needs at least 3 minutes according to the scanning reservation information of the patient, the medical staff may consider that the bulb is not enough to support the paying-off scanning of the patient currently. At the moment, medical staff can trigger and generate a preheating-free scanning triggering instruction to the CT equipment through a main control interface of the CT equipment.

In another alternative implementation, when the bulb of the CT apparatus is in the inactive state, and the remaining free time of the bulb is greater than 0 and does not exceed a preset threshold, for example, 30 minutes, the CT apparatus may automatically trigger generation of the scan trigger instruction without preheating.

In yet another optional implementation manner, when the bulb of the CT device is in a non-working state, and the CT device monitors that the preheating-free remaining available time of the bulb is greater than 0 and does not exceed a preset threshold, the preheating-free remaining available time of the bulb may be output, and when the medical care personnel determines that the preheating-free remaining available time of the bulb does not exceed the preset threshold through the output preheating-free remaining available time of the bulb, a scanning trigger instruction that is free of preheating may be generated by triggering the CT device through a main control interface of the CT device.

In yet another optional implementation manner, when the bulb of the CT device is in a non-working state, and the CT device monitors that the preheating-free remaining available time of the bulb is greater than 0 and does not exceed a preset threshold, the CT device may output a prompt message that the pay-off scanning needs to be performed, where the prompt message may be represented by turning on or off a signal lamp or by a preset sound prompt, which is not limited in this application. After receiving the prompt message, the medical staff can trigger and generate a preheating-free scanning triggering instruction to the CT device through the main control interface of the CT device.

Next, based on the above-described process of detecting the preheating-free scan trigger instruction by the CT device, a process of obtaining a corresponding preheating-free scan condition by the CT device is described:

in an alternative implementation, the CT apparatus may obtain the target preheat-free scan sequence through the detected scan reservation information of the object. Specifically, the scan reservation information of the object may include a scan protocol, the scan protocol may correspond to at least one scan sequence, and the CT device may determine a target preheat-free scan sequence from the at least one scan sequence corresponding to the scan protocol.

For example, as shown in table 1 below, an example of a scan sequence corresponding to a scan protocol included in the scan reservation information of the subject is:

TABLE 1

The above table 1 includes two Scan sequences, from which the CT apparatus can determine a target preheat-free Scan sequence, for example, "Scan-1" is determined as the target preheat-free Scan sequence. In practical applications, there may be various ways to determine a target preheating-free scan sequence from at least one scan sequence, for example, selecting the scan sequence arranged at the top according to the arrangement order of the scan sequences, and the like, which is not limited in this application.

In another alternative implementation, the CT device may obtain a target warmup-free scan sequence based on historical patient scan information. Specifically, a patient information database for recording historical patient scanning information may be stored in the CT device, and a corresponding relationship between patient scanning IDs and patient scanning sequences is stored in the patient information database, where each patient scanning ID corresponds to at least one patient scanning sequence. The CT device may obtain the patient scanning sequence with the largest occurrence number by counting through the patient scanning sequence corresponding to each patient ID, and use the patient scanning sequence with the largest occurrence number as the target preheating-free scanning sequence, where the detailed description of the above process may refer to the description of the embodiment shown in fig. 2, which is not described in detail herein first.

In the two alternative implementations described above, after determining the target preheat-free scan sequence, the CT device may acquire an air correction scan condition corresponding to the target preheat-free scan sequence.

For example, a target preheating-free scanning sequence acquired by the CT apparatus is shown in table 1, and table 2 is an example of air correction scanning conditions corresponding to the target preheating-free scanning sequence:

TABLE 2

In yet another optional implementation manner, the CT device may acquire a preset scanning parameter, and generate a corresponding preheating-free scanning condition according to the preset scanning parameter. The preset scan parameters may include focus mode, focus position, focus size, bulb voltage, scan resolution, rotation speed, slice gear, and the like.

Step 102: and executing the preheating-free paying-off scanning according to the preheating-free scanning condition, so that the bulb tube of the medical equipment is always in a working state.

In an optional implementation manner, the CT device may set air correction scanning parameters of the CT device according to scanning parameters included in the acquired air correction scanning conditions; and controlling each device to perform initialization adjustment so that the CT device is in an environment where air correction can be performed, for example, reading the position of the scanning bed, and if the position of the scanning bed is not zeroed, controlling the position of the scanning bed to be zeroed; reading the inclination angle of the rack, and controlling the inclination angle of the rack to return to zero if the inclination angle of the rack does not return to zero; reading the rotation position of the rack, and controlling the rotation position of the rack to be zero if the rotation position is not zero; and so on. Subsequently, the CT apparatus may perform air scan correction according to the set air correction scan parameters and generate air correction data under the preheat-free scan condition.

In the implementation mode, the CT equipment executes air scanning correction according to the obtained air correction scanning conditions, so that preheating-free paying-off scanning of the bulb tube is realized, air scanning correction is conveniently executed, air correction data are generated, and the quality of a CT image is improved. Particularly, before a patient needs to perform the paying-off scanning, in order to prevent the CT device from being preheated, the corresponding air correction scanning condition is obtained through the scanning reservation information of the patient, the air scanning correction is performed according to the air correction scanning condition, the latest air correction data can be obtained, and therefore the quality of the CT image to be obtained is effectively improved.

In addition, after the CT device completes one air scanning correction according to the acquired air correction scanning condition, the update time corresponding to the air correction scanning condition may be updated in the air correction table. For example, table 3 is an example of an air correction table after completing one air scan correction according to the air correction scan conditions exemplified in table 2 above:

TABLE 3

In table 3, since the update time corresponding to the air correction scanning condition is updated, subsequently, if the CT device has reached the preset air correction table maintenance time, the CT device may determine that the air correction data corresponding to the air correction scanning condition has been updated according to the update time corresponding to the air correction scanning condition, and may not perform air correction again according to the air correction scanning condition, thereby updating the air correction table conveniently and improving the maintenance efficiency of the air correction table.

Referring to fig. 2, a flowchart of another embodiment of a control method for bulb tube preheating-free scanning according to the present application is shown, and the embodiment describes in detail a process of obtaining a target preheating-free scanning sequence according to historical patient scanning information based on the embodiment shown in fig. 1, and includes the following steps:

step 201: and loading a patient information database, wherein the patient information database stores the corresponding relation between patient scanning IDs and patient scanning sequences, and each patient scanning ID corresponds to at least one patient scanning sequence.

In this embodiment, each time the medical device scans a patient, the medical device may assign a patient scanning ID to the patient, and may scan the patient using at least one patient scanning sequence. The correspondence between the patient scan ID and the patient scan sequence may be stored in a patient information database, wherein each patient scan ID corresponds to at least one patient scan sequence.

When obtaining the corresponding scanning conditions according to the historical patient scanning information, the medical device may first load a patient information database, as shown in table 4 below, which is an example of a patient information database:

TABLE 4

In the above table 4, taking the patient Scan ID as ID-1 as an example, ID-1 corresponds to two patient Scan sequences, Scan-1 and Scan-2 respectively, which indicate that the patient corresponding to ID-1 has been scanned by Scan-1 and Scan-2 respectively during the actual clinical Scan. In table 4 above, each patient scan sequence may include a plurality of scan parameters, which are not specifically shown in table 4, and refer to the scan parameters in the patient scan sequence included in the scan appointment information illustrated in table 1 above.

Step 202: traversing the patient scanning sequence corresponding to each patient ID, determining whether the patient scanning sequence is repeated with a plurality of scanning sequences recorded in the patient scanning condition table, if not, executing step S203; if so, step S204 is executed.

Step S203: writing a patient scanning sequence into a patient scanning condition table, and setting the corresponding use times as 1; step S205 is performed.

Step S204: in the patient scanning condition table, the number of uses corresponding to the scanning sequence repeated by the patient scanning sequence is added by 1.

In this embodiment, the medical device may traverse the patient scan sequence corresponding to each patient ID, and maintain a patient scan condition table according to the traversal result, for example, table 5 below is an example of the patient scan condition table:

TABLE 5

The process of traversing the patient scanning sequence corresponding to each patient ID and maintaining the patient scanning condition table shown in table 5 according to the traversal result is as follows:

the CT device may sequentially traverse the patient scanning sequence corresponding to each patient scanning ID in the patient information database illustrated in table 4, for example, first execute step S202, i.e., traverse the scanning parameters in Scan-1 of ID-1, when the patient scanning condition table illustrated in table 5 is empty, determine that Scan-1 of ID-1 is not repeated with a plurality of scanning sequences recorded in the patient scanning condition table, continue to execute step S203, i.e., write Scan-1 of ID-1 into table 5, and set the number of uses corresponding to ID-1(Scan-1) to 1 in table 5; continuously traversing the Scan parameters in Scan-2 of ID-1, at this time, one Scan sequence ID-1(Scan-1) is recorded in table 5, comparing the Scan parameters in Scan-2 of ID-1 with the Scan parameters of ID-1(Scan-1) recorded in table 5, if the comparison result that each Scan parameter is consistent is obtained, it can be determined that Scan-2 of ID-1 is repeated with several patient Scan sequences in the patient Scan condition table, for example, with ID-1(Scan-1) recorded in table 5, and continuously executing step S204, i.e., adding 1 to the number of uses corresponding to ID-1(Scan-1) recorded in table 5. According to the above process, until all patient scanning sequences corresponding to the patient IDs are traversed.

Step S205: after traversing the patient scanning sequence corresponding to each patient ID, taking the scanning sequence with the highest using frequency in the patient scanning condition table as the target preheating-free scanning sequence.

In this embodiment, after traversing the patient Scan sequence corresponding to each patient ID, the CT device takes the Scan sequence with the highest use frequency in the patient Scan condition table illustrated in table 5 as the target preheating-free Scan sequence, for example, if the highest use frequency is 78, then ID-3(Scan-1) is taken as the target preheating-free Scan sequence.

In addition, it should be noted that if more than one scan sequence with the highest number of times of use in the patient scan condition table exemplified in table 5 is determined, that is, more than one determined target preheating-free scan sequence is determined. Then, the air correction scanning condition corresponding to each target preheating-free scanning sequence can be obtained subsequently, the updating time of each air correction scanning condition is obtained, and finally the air correction scanning condition with the updating time longest from the current time is selected.

As can be seen from the above embodiments, the patient scanning sequence with the largest occurrence number is used as the target preheating-free scanning sequence by traversing the patient scanning sequence of the medical device, and then the air correction scanning condition corresponding to the target preheating-free scanning sequence is obtained. Because preheating-free paying-off scanning is executed according to the obtained air correction scanning conditions, compared with the traditional bulb tube preheating process, ray beams generated by the bulb tube are less, so that the bulb tube loss can be reduced, and the service life of medical equipment is prolonged; meanwhile, the target preheating-free scanning sequence has the highest use frequency, so that the air correction scanning conditions corresponding to the target preheating-free scanning sequence are commonly used for the medical institution where the medical equipment is located, so that the air scanning correction can be conveniently carried out, the quality of CT images is improved, and the use requirements of the medical institution are met to a greater extent.
