Description

Technical Field

[0001] The present invention relates to the field of imaging medicine, and particularly to an interactive method, system and storage medium for imaging examination applications based on anatomical atlases. Background Art

[0002] Imaging examinations are one of the most commonly prescribed examination items by doctors, covering almost all systems, organs and any body parts of the whole body. Currently, imaging examination applications are arranged in text form in the imaging examination column of outpatient or inpatient case systems, mixed with men and women, with numerous items and lack of prominence. When work is busy, it is easy to select the wrong gender, left or right position or different organs, which is inconvenient to operate and error-prone, bringing inconvenience and even accidents to doctors and patients. For example, in the secondary options of color Doppler ultrasound vascular examinations, there are only for lower limb vessels: bilateral lower limb arteries, bilateral lower limb veins, right lower limb artery, right lower limb vein, left lower limb artery, left lower limb vein. In addition, there are upper limb vessels, neck vessels, abdominal vessels and their corresponding multiple secondary options. Therefore, incorrect examination forms are often issued during normal work. Usually, doctors only find the error when they see the report after the examination, and at this time, the mistake has already occurred, seriously delaying the condition and even triggering medical disputes. The reason lies in the imperfect current examination form issuing system, and the sensitivity of humans to text is far less than that of graphics. Therefore, the imaging examination form issuing system module needs to be designed to be more intelligent and graphically visual, which can greatly reduce the error rate of application form issuance.

[0021] The following describes the implementation manners of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0022] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0023] For the purpose of illustration, some exemplary embodiments of the present invention are described. It should be understood that the present invention can be implemented in other ways not specifically shown in the drawings.

[0024] As Figure 1 、 Figure 2 shown, this embodiment provides an image examination application interaction method based on an anatomical atlas, which is characterized by including:

[0025] S1. Receive patient information, including gender, medical history, and examination type instructions; in this embodiment, the patient information is obtained in real time through the HIS system (Hospital Information System) interface. For the patient ID received by the HIS system, the RESTful API is called to obtain information such as gender, age, and allergy drugs (such as iodine contrast agent allergy markers).

[0026] S2. Dynamically generate a corresponding three-dimensional anatomical atlas according to the gender, and the mutually exclusive organs in the male and female atlases are automatically hidden; avoid the occurrence of gender-exclusive items, thereby eliminating the possibility of prescribing male (female) examination items for female (male) patients.

[0027] S3. Display the anatomical structures in layers in the graphical interface according to the three-dimensional anatomical atlas: as Figure 2 、 Figure 3 shown, divide the human body system modules according to the examination type, and different colors are used to display different human body system modules. The human body system modules include the vascular system, the skeletal system, and the visceral system. During this process, the name of the anatomical structure in the area where the mouse pointer hovers can be displayed in the form of text. In the text, for the anatomical structures that exist on both sides, the left and right positions are clearly marked.

[0028] S4. Respond to user interaction operations: Single click to select the examination site and generate a selection mark; double click to deselect, and the selection mark disappears; when multiple sites are selected simultaneously, the system automatically detects conflicting items and pops up a warning for the conflicting items. Use a mask with color features or texture features as the selection mark. For example, when selecting blood vessels in color Doppler ultrasound, blood vessels in red and blue colors will appear throughout the body. The red blood vessels are arteries and the blue ones are veins. Single or all selections are available. When selected, the corresponding blood vessels turn black.

[0029] In a specific embodiment, the user interface uses WebGL technology to achieve hierarchical rendering, supporting differential display of examination types such as CT, MRI, and ultrasound. The arterial layer is rendered in semi-transparent red with RGBA(255, 0, 0, 0.6), and the venous layer is rendered in semi-transparent blue with RGBA(0, 0, 255, 0.6). Click interaction: When a blood vessel is selected, the transparency is adjusted to 0.9, and a black outline (line width 2px) is added, or a semi-transparent template is added as the selection mark.

[0030] During the process of automatically detecting conflicting items, if a male patient selects "uterine ultrasound", then call alertConflict("gender incompatible") of the UI interface and automatically deselect. If MRI and enhanced CT examinations are applied on the same day, then calculate the contrast agent metabolism time. If the interval is < 24 hours, a warning box will pop up and submission will be prohibited.

[0031] In step S4, according to the selected examination item, call the knowledge graph to generate pre-examination preparation tips, including contraindication verification and preparation matters. For example, a CT examination of the urinary system will prompt the patient to drink 500 ml of water and hold urine 30 minutes in advance, which appears in a prominent position. Such as when simultaneously selecting CT enhanced scan and metal implant reminder. Such as for patients with abnormal renal function → contrast agent use warning.

[0032] In this embodiment, the node types of the knowledge graph include: examination item, preparation matter, contraindication, conflict rule. Relationship definition: For example, "urinary CT → need to drink 500 ml of water", "abnormal renal function → iodine contrast agent is prohibited". According to the patient information and examination item, preparation matters, contraindications, and conflict rules can be obtained.

[0033] S5: Generate an electronic application form and synchronously push it to the imaging department and the patient terminal, and trigger the timing reminder function.

[0034] By dynamically generating an anatomical atlas that matches the gender (such as automatically hiding the prostate examination option for female patients and hiding uterine-related examinations for male patients), errors caused by gender misselection are completely eliminated. At the same time, mutually exclusive items are verified (such as arteries and veins cannot be selected simultaneously, and the interval between the use of contrast agents for MRI and enhanced CT is insufficient), and incorrect operations are intercepted immediately. Data from pilot hospitals shows that the gender-related error rate has dropped from 7.2% to 0%.

[0035] Through a three-dimensional anatomical atlas with hierarchical rendering (such as red and blue double-layered blood vessels), doctors can visually locate the examination site, and the average order placement time is shortened from 8.5 minutes of the traditional text menu to 3.2 minutes, with an efficiency improvement of 276%. The knowledge graph automatically matches examination preparation matters (such as "drink 500 ml of water in advance for urinary CT") and contraindication prompts (such as iodine contrast agents are prohibited for patients with abnormal renal function), reducing the time for doctors to manually consult the guidelines.

[0036] The system is connected to the patient's allergy history and test indicators (such as creatinine value) in real time, automatically shielding high-risk items (such as enhanced CT is prohibited for patients with iodine allergy), avoiding medical accidents caused by human negligence. For examinations that require an interval (such as MRI and enhanced CT), the system automatically calculates the contrast agent metabolism cycle and adjusts the appointment time to ensure the compliance of medical operations.

[0037] The system of the present invention supports medical data protocols such as HL7 and DICOM, and is deeply integrated with HIS and PACS systems without the need to transform the existing hospital information architecture. Modules such as blood vessel layering and contraindication rule bases can be independently expanded to adapt to the needs of different specialties (such as strengthening the blood vessel examination logic in the cardiovascular specialty).

[0038] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
