Description

background Technical Field

[0002] The present disclosure relates to computer-assisted recognition, and more particularly to computer-assisted recognition for medical procedures. Background Art

[0004] In the past, failure to correctly identify a patient could result in transfusion errors, medication errors, incorrect personnel procedures, test errors, and / or incorrect medical procedure sites, etc. Patient misidentification can be a root cause of medical procedure errors. Areas where patient misidentification may occur may include surgical interventions, transfusions, medication administration, and / or phlebotomy, etc. Patient misidentification may be caused by name structure (e.g., very similar names), inaccurate dates of birth, clothing that conceals identity, unconscious patients, errors in registering patients via computerized systems, absence of an identification wristband, identification of a different (e.g., incorrect) patient by the identification wristband, etc. In addition, failure to correctly identify a patient's eyes may also result in transfusion errors, medication errors, incorrect personnel procedures, test errors, and / or incorrect medical procedure sites, etc. Summary of the Invention

[0005] The present disclosure provides a system capable of receiving an identification of a first patient. In one example, the system may receive the identification of the first patient from medical personnel. In another example, the system may receive the identification of the first patient by scanning a patient's wristband. The system may further retrieve first eye identification information based at least on the identification of the first patient, the first eye identification information including a first plurality of iris structures associated with a first eye of the first patient. The system may further determine a second plurality of iris structures of an eye of the current patient. The system may further determine whether the second plurality of iris structures matches the first plurality of iris structures. If the second plurality of iris structures matches the first plurality of iris structures, the system may further provide an indication that the first eye has been correctly identified. If the second plurality of iris structures does not match the first plurality of iris structures, the system may further provide an indication that the first eye has not been correctly identified.

[0006] The first eye identification information may further include at least one distance measurement associated with the first eye. For example, the at least one distance measurement associated with the first eye may include at least one of a distance measurement from the cornea of ​​the first eye to the lens of the first eye, a distance measurement from the lens of the first eye to the retina of the first eye, a corneal thickness of the first eye, and a lens thickness of the first eye. The system may further determine at least one distance measurement for the current patient's eye. For example, the at least one distance measurement associated with the current patient's eye may include at least one of a distance measurement from the cornea of ​​the current patient's eye to the lens of the current patient's eye, a distance measurement from the lens of the current patient's eye to the retina of the current patient's eye, a corneal thickness of the current patient's eye, and a lens thickness of the current patient's eye. The system may further determine whether the at least one distance measurement for the current patient's eye matches the at least one distance measurement associated with the first eye. If the second plurality of iris structures matches the first plurality of iris structures and the at least one distance measurement of the current patient's eye matches the at least one distance measurement associated with the first eye, the system may perform the providing of the indication that the first eye has been correctly identified. If the at least one distance measurement of the current patient's eye does not match the at least one distance measurement associated with the first eye, the system may perform the providing of the indication that the first eye has not been correctly identified.

[0007] The system may further retrieve medical procedure information based at least on the identification of the first patient and one of a second plurality of iris structures of the current patient's eye.The system may further provide the medical procedure information via at least one of a display and a microscope integrated display.

[0008] A first iris structure in the first plurality of iris structures may be separated from a second iris structure in the first plurality of iris structures at a first angle relative to a center of the pupil of the first eye. A first iris structure in the second plurality of iris structures may be separated from a second iris structure in the second plurality of iris structures at a second angle relative to a center of the pupil of the current patient's eye. For example, to determine whether the second plurality of iris structures matches the first plurality of iris structures, the system may further determine whether the second angle matches the first angle.

[0009] A first iris structure of the first plurality of iris structures can be a first distance from a pupil center of the first eye. A first iris structure of the second plurality of iris structures can be a second distance from a pupil center of the current patient's eye. For example, to determine whether the second plurality of iris structures matches the first plurality of iris structures, the system can further determine whether the second distance matches the first distance.

[0010] The current patient can be the first patient. The current patient's eye can be a second eye of the first patient different from the first eye. In one example, the first eye can be a right eye of the patient and the second eye can be a left eye of the patient. In another example, the first eye can be a left eye of the patient and the second eye can be a right eye of the patient.

[0011] The present disclosure further includes a non-transitory computer-readable memory device having instructions that, when executed by a processor of the system, cause the system to perform the above steps.

[0036] In the following description, details are set forth by way of examples to facilitate discussion of the disclosed subject matter. However, it will be apparent to one of ordinary skill in the art that the disclosed embodiments are exemplary and not exhaustive of all possible embodiments.

[0037] As used herein, a reference numeral refers to a class or type of entity, and any letter following such a reference numeral refers to a specific instance of a particular entity of that class or type. Thus, for example, a hypothetical entity designated '12A' may refer to a particular instance of a particular class / type, and generally, the designation '12' may refer to the set of instances belonging to that particular class / type, or any one instance of that particular class / type.

[0038] Medical systems can be used to identify patients. In one example, a first medical system can be used at a first time to identify a patient before a medical procedure. In another example, a second medical system can be used at a second time to identify a patient before a medical procedure. The second time can be later than the first time. In one example, the first medical system can be used at a doctor's office. In another example, the second medical system can be used at a surgical facility.

[0039] The first medical system may associate two or more identification attributes associated with the patient. For example, the two or more identification attributes associated with the patient may include two or more of the following: the patient's name, the patient's address, the patient's telephone number, the patient's government-issued identification number or string, the patient's date of birth, the patient's first medical facility identifier, and the patient's first eye identifier. The patient's first eye identifier may be used to identify the patient and / or the patient's eye via an eye recognition process, method, and / or system.

[0040] The second medical system may associate two or more identification attributes associated with the patient. For example, the two or more identification attributes associated with the patient may include two or more of the following: the patient's name, the patient's address, the patient's telephone number, the patient's government-issued identification number or string, the patient's date of birth, the patient's first medical facility identification, the patient's second first medical facility identification, the patient's first eye identification, and the patient's second eye identification. The second medical system may utilize an eye recognition process, method, and / or system to obtain the patient's second eye identification and determine whether the patient's first eye identification and the patient's second eye identification match. If the patient's first eye identification and the patient's second eye identification match, a medical procedure associated with the patient may be performed. For example, the medical procedure associated with the patient may include a surgical procedure associated with the patient.

[0041] If the patient's first eye identifier and the patient's second eye identifier match, a medical procedure can be retrieved based at least on the identifier associated with the patient. The identifier associated with the patient can include the patient's first eye identifier and / or the patient's second eye identifier. For example, the medical system can retrieve medical procedure information from a database. The medical system can retrieve medical procedure information from a database based at least on the identifier associated with the patient. In one example, the database can use the patient's identifier as a key for multiple medical procedure information. In another example, the database can use the iris structure of the corresponding eye as a key for multiple medical procedure information. The eye identifier of the corresponding patient can include information associated with the iris structure of the corresponding one or more eyes. The eye identifier of the corresponding patient can include information associated with one or more measurements of the corresponding one or more eyes. The medical procedure can be automatically retrieved. For example, automatically retrieving the medical procedure can include automatically loading the medical procedure. The medical procedure can include a pre-planned treatment plan. For example, a pre-planned treatment plan can be automatically loaded for a matching patient and / or matching patient eye. Automatically loading the medical procedure can allow a physician (e.g., a surgeon) to begin and / or initiate the medical procedure. The medical procedure can be displayed via the microscope's integrated display and / or a display of the medical system. In one example, this can reduce the amount of time a medical procedure takes compared to not automatically loading the medical procedure. In another example, this can reduce one or more possible errors in performing one or more medical procedures. If a medical procedure is automatically loaded for a physician based on at least an identifier associated with a patient, the medical procedure will not be performed on an incorrect patient.

[0042] If the patient's first eye identifier and the patient's second eye identifier do not match, then the medical procedure associated with the patient will not be performed. In one example, an error or warning may be issued, which may alert medical personnel that the patient was not correctly identified. In another example, an error or warning may be issued, which may alert medical personnel that the patient's eye was not correctly identified.

[0043] One or more eye recognition systems, one or more eye recognition methods, and / or one or more eye recognition processes can be used to identify a patient's eye. For example, eye recognition can be based at least on identifying the patient by analyzing patterns based at least on one or more structures of the patient's eye and / or one or more shapes of one or more parts of the patient's eye. In one example, eye recognition can identify eye features by extracting landmarks and / or features from an image of the patient's eye. In a second example, eye recognition can identify eye features by identifying one or more structures of the iris of the patient's eye. In a third example, eye recognition can identify eye features by identifying one or more patterns of the retina of the patient's eye. In another example, eye recognition can identify eye features by determining one or more depth measurements of the patient's eye. The depth measurement of the patient's eye can include a distance measurement from the cornea of ​​the patient's eye to the lens of the patient's eye. The depth measurement of the patient's eye can include a distance measurement from the lens of the patient's eye to the retina of the patient's eye. The one or more eye recognition systems, one or more eye recognition methods, and / or one or more eye recognition processes can determine data associated with the patient's eye. The data associated with the patient's eye can include a template. For example, a template may be distinguishable from a photograph because the template may include data that may be used to distinguish an eye of a first patient from an eye of a second patient that is different from the first patient.

[0044] One or more eye recognition systems, one or more eye recognition methods, and / or one or more eye recognition processes can utilize three-dimensional technology that utilizes one or more projectors and / or one or more sensors, etc., to determine information about the shape of the patient's eye. For example, information about the shape of the patient's eye can be used to determine one or more features of the surface of the patient's eye. The one or more features of the surface of the patient's eye can include, for example, an eye outline. An advantage of utilizing three-dimensional eye recognition technology can be that the three-dimensional eye recognition technology can be unaffected by changes in lighting. One or more eye recognition systems, one or more eye recognition methods, and / or one or more eye recognition processes can utilize multiple image sensors. For example, the multiple image sensors can include multiple cameras. Three-dimensional eye recognition technology can utilize multiple image sensors.

[0045] The eye recognition system may include one or more image capture devices. For example, the one or more image capture devices may include one or more cameras. The eye recognition system may include one or more light projectors. In one example, the light projector may project infrared light. In another example, the light projector may include a laser. The eye recognition system may determine a location on the patient's eye. For example, the location on the patient's eye may be used to determine a template of the patient's eye. The template of the patient's eye may be associated with the topography of the patient's eye. The template of the patient's eye may be used for eye recognition. In one example, the template of the patient's eye may be compared with another template when confirming or denying the identity of the patient. In another example, the template of the patient's eye may be compared with another template when confirming or denying the identity of the patient's eye.

[0046] A medical procedure associated with a patient may include a portion of the patient (e.g., the site of the medical procedure). For example, a portion of the patient may be similar to another portion of the patient. For example, the patient's right eye may be similar to the patient's left eye. For example, the patient's right eye may appear similar to the patient's left eye. A medical procedure associated with a patient may target one portion of the patient but not another portion of the patient. For example, a medical procedure associated with a patient may target the patient's right eye but not the patient's left eye. The second medical system may utilize computer vision processes, methods, and / or systems to distinguish the portion of the patient from other portions of the patient. The computer vision processes, methods, and / or systems may utilize eye recognition processes, methods, and / or systems to distinguish the portion of the patient from other portions of the patient. For example, the second medical system may determine that a surgical tool or instrument is in an area not associated with the portion of the patient. If the second medical system determines that the surgical tool or instrument is in an area not associated with the portion of the patient, the second medical system may issue a warning or error. In one example, if a medical procedure is targeted at the patient's right eye (e.g., the site of the medical procedure), and if the second medical system determines that the surgical tool or instrument is in an area not associated with the patient's right eye, the second medical system may issue a warning or error. In another aspect, if the medical procedure is directed to the patient's right eye (e.g., the site of the medical procedure), and if the second medical system determines that the surgical tool instrument is within the area associated with the patient's left eye, the second medical system can issue a warning or error.

[0047] Now turn Figure 1A, which illustrates an example medical system. As shown, medical system 110 can be used with patient 120. As shown, medical system 110 can include computer system 112. Computer system 112 can be communicatively coupled to displays 116A and 116B. As an example, computer system 112 can be integrated with display 116. Computer system 112 can be communicatively coupled to biometric device 114. In one example, biometric device 114 can include one or more cameras. In another example, biometric device 114 can include a three-dimensional scanner. Biometric device 114 can be used to perform biometric measurements on an eye 122 of patient 120. As shown, display 116A can display an image 130A associated with eye 122 of patient 120. As shown, display 116B can display an image 130B associated with eye 122 of patient 120.

[0048] The computer system 112 may determine eye identification information. For example, the eye identification information may include biometric information associated with the eye 122 of the patient 120. The biometric information associated with the eye 122 may include one or more of a vascular pattern of the sclera of the eye 122, an iris structure of the eye 122, a position of the iris structure of the eye 122, a distance measurement from the cornea of ​​the eye 122 to the lens of the eye 122, a distance measurement from the lens of the eye 122 to the retina of the eye 122, a corneal tomography scan of the eye 122, a retinal pattern of the eye 122, a corneal thickness of the eye 122, a lens thickness of the eye 122, and a wavefront measurement.

[0049] As shown, display 116B can display a pattern of blood vessels 132 of the sclera of eye 122. As illustrated, display 116B can display the structure of iris 134A-134C of eye 122. As shown, display 116B can display display areas 136A-136D. In one example, display area 136 can display other biometric information associated with eye 122, such as a distance measurement from the cornea of ​​eye 122 to the lens of eye 122, a distance measurement from the lens of eye 122 to the retina of eye 122, the location of iris structure 134, corneal tomography, or wavefront measurement information. In another example, display area 136 can display any information associated with patient 120.

[0050] A person 150 can operate the medical system 110. For example, the person 150 can be a medical professional. The person 150 can input identification information associated with the patient 120 into the computer system 112. The identification information associated with the patient 120 can include one or more of the following: a name of the patient 120, an address of the patient 120, a phone number of the patient 120, a governmentally issued identification number of the patient 120, a governmentally issued identification string of the patient 120, and a date of birth of the patient 120, among others. In one example, the computer system 112 can associate the identification information associated with the patient 120 with eye identification information. In another example, the computer system 112 can associate the identification information associated with the patient 120 with a template.

[0051] Prior to the computer system 112 associating the identification information associated with the patient 120 with the eye identification information, the person 150 can verify one or more portions of the identification information associated with the patient 120. For example, one or more portions of the identification information associated with the patient 120 can have been stored via a storage device accessible by the computer system 112 prior to use of the medical system 110 for the patient 120. The person 150 can configure data associated with a portion of the patient 120. For example, the person 150 can configure data associated with a right eye of the patient 120.

[0052] The person 150 can provide medical procedure information associated with the patient 120 to the computer system 112. The medical procedure information can be associated with a medical procedure. The medical procedure information can be the identification information associated with the patient 120. The computer system 112 can store the medical procedure information. For example, the computer system 112 can store the medical procedure information for later use. The medical procedure information can be associated with a surgery. For example, the medical procedure information can be retrieved prior to a surgery. The medical procedure information can be used during a medical procedure. For example, the medical procedure can include a surgery.

[0053] Turning now to Figure 1B, an example of a biometric device is shown. As shown, the biometric device 114 can include image sensors 160A-160C. For example, the image sensors 160 can include cameras. As shown, the biometric device 114 can include light projectors 162A-162C. In one example, the light projectors 162 can project visible light. In another example, the light projectors 162 can project infrared light. The light projectors 162 can project circles and / or dots onto the patient’s eye. The image sensors 160 can receive reflections of the circles and / or dots projected onto the patient’s eye. The computer system can determine one or more locations and / or one or more templates associated with the patient’s eye based at least on the reflections of the circles and / or dots projected onto the patient’s eye. As shown, the biometric device 114 can include depth sensors 164A-164C. The depth sensors 164 can include light projectors 162. The depth sensors 164 can include optical sensors. As shown, the biometric device 114 can include an optical low coherence reflectometry (OLCR) device 166. As shown, the biometric device 114 can include a wavefront device 168.

[0054] The wavefront device 168 can include one or more of a light source and a wavefront sensor, among others. The light source can provide a first light wave to the eye 122. The wavefront sensor can receive a first perturbed light wave from the eye 122 based at least on the first light wave. In one example, the wavefront device 168 can determine a first optical correction based at least on the first perturbed light. In another example, the computer system can determine the first optical correction based at least on the first perturbed light. The wavefront device 168 can provide data to the computer system based at least on the first perturbed light wave. For example, the computer system can determine the first optical correction based at least on the data from the wavefront device 168.

[0055] Any two or more of the image sensors 160, the light projectors 162, the depth sensors 164, the OLCR device 166, and the wavefront device 168 can be combined. One or more of the image sensors 160A-160C, one or more of the light projectors 162A-162C, one or more of the depth sensors 164A-164C, the OLCR device 166, and / or the wavefront device 168, among others, can produce data that can be utilized by the computer system.

[0056] Now turning to Figures 2A to 2C , an example of measurements associated with an eye is shown. As Figure 2AAs shown, measurements 210A, 212A, and 214A may be associated with eye 122. In one example, measurement 210A may be associated with a distance measurement from cornea 220 of eye 122 to lens 222 of eye 122. In a second example, measurement 212A may be associated with a distance measurement from lens 222 of eye 122. In another example, measurement 214A may be associated with a distance measurement from lens 222 of eye 122 to retina 224 of eye 122. Measurements 210A, 212A, and 214A may be on-axis measurements.

[0057] like Figure 2B As shown, measurements 210B, 212B, and 214B may be associated with eye 122. In one example, measurement 210B may be associated with a distance measurement from cornea 220 of eye 122 to lens 222 of eye 122. In a second example, measurement 212B may be associated with a distance measurement from lens 222 of eye 122. In another example, measurement 214B may be associated with a distance measurement from lens 222 of eye 122 to retina 224 of eye 122. Measurements 210B, 212B, and 214B may be off-axis measurements. For example, measurements 210B, 212B, and 214B may be offset from axis 230. Measurements 210B, 212B, and 214B may be offset from axis 230 in a vertical direction. Measurements 210B, 212B, and 214B may be offset from axis 230 in a horizontal direction.

[0058] like Figure 2C As shown, measurements 210C, 212C, and 214C may be associated with eye 122. In one example, measurement 210C may be associated with a distance measurement from cornea 220 of eye 122 to lens 222 of eye 122. In a second example, measurement 212C may be associated with a distance measurement from lens 222 of eye 122. In another example, measurement 214C may be associated with a distance measurement from lens 222 of eye 122 to retina 224 of eye 122. Measurements 210C, 212C, and 214C may be off-axis measurements. For example, measurements 210C, 212C, and 214C may be offset from axis 230. Measurements 210C, 212C, and 214C may be offset from axis 230 in a vertical direction. Measurements 210C, 212C, and 214C may be offset from axis 230 in a horizontal direction.

[0059] The biometry device 114 can perform measurements associated with the eye 122. For example, the biometry device 114 can determine one or more of the measurements 210, 212, and 214, etc. The measurements 210, 212, and / or 214, etc. can be used to determine a shape of the eye 122. The biometry device 114 can perform measurements associated with the eye 122 without contacting the eye 122. For example, the biometry device 114 can determine one or more of the measurements 210, 212, and 214, etc. without contacting the eye 122. The OLCR device 166 can determine one or more of the measurements 210, 212, and 214, etc. without contacting the eye 122. For example, the OLCR device 166 can determine one or more of the measurements 210, 212, and 214, etc. using a single-beam interferometer or a multi-beam interferometer and a beam deflection mechanism to determine one or more of the measurements 210, 212, and 214, etc. along an axis 230 (e.g., a visual axis) and / or a certain number of degrees horizontally and / or vertically from the axis 230.
