This invention relates generally to method of reducing patient identification errors in medical images through customization of medical images and more particularly to, a method and system for providing patient identification information in medical images in patient's preferred language.
Conventionally, English is used as a common language in annotating medical images and reports. Once the medical report and image film are given to a patient, the patient needs to keep it safe and re produce the same during further examination stages.
However in rural area the literacy, especially the English literacy is low and the people may be well versed with their local language only. In some countries, there are different languages and people may not be comfortable with English language or any other common language.
Since almost all hospitals use English as the mode of communication, this flows down to even the reports or films that is generated and handed over to the patient. As medical reports and films are in English language, the patient ends up in confusion when they have to store or bring it back for repeated visits to the hospital and this could result in misplacing the reports.
In a family, all the family members might need to store their diagnostic reports or diagnostic images. Generally, the patient parameters are annotated in the medical image in English language. Unfortunately, the people who are not able to read English, may not be able to identify his or her own films or reports. This results in misplacing or destroying the medical reports in error, as the patient might get confused with other family member's report. This leads to repeat travel to the hospitals or extra scans in situations that demand urgent attention, rising both the cost/time to treat the patient.
In the event of clinician not verifying the authenticity of the images, he may consider the image brought by the patient as genuine and this may result in wrong treatment plans.
Thus there exist a need for an improved method and system for customizing medical images using patient's preferred or local language.
The above-mentioned shortcomings, disadvantages and problems are addressed herein which will be understood by reading and understanding the following specification.
One embodiment of the present invention provides a method of customizing medical images based on patient preference. The method comprises: receiving patient preference on displaying patient identification information in a medical image; providing customized patient identification information on the image based on the patient preference; and storing the image with customized patient information in a media.

To the extent that the figures illustrate diagrams of the functional blocks of various embodiments, the functional blocks are not necessarily indicative of the division between hardware circuitry. Thus, for example, one or more of the functional blocks (e.g., processors or memories) may be implemented in a single piece of hardware (e.g., a general purpose signal processor or a block of random access memory, hard disk, or the like). Similarly, the programs may be stand alone programs, may be incorporated as subroutines in an operating system, may be functions in an installed software package, and the like. It should be understood that the various embodiments are not limited to the arrangements and instrumentality shown in the drawings.
Embodiments of the present invention provide a method and system for customizing medical images. The method further discloses displaying patient identification parameter such as patient's name in a language preferred by the patient. This will help easy identification of the medical film or report corresponding to a patient even if the patient doesn't have the knowledge of English language. In an embodiment, a graphical interface is provided on an image viewer or on a reporting tool, such that patient information could be incorporated into the image in patient's preferred language.
The term “patient identification information” referred in the specification need not refer to one parameter, but includes a list of parameters unless otherwise specified and need not be limited to the examples mentioned in the specification. Rather, the patient identification information may be any unique information related to patient. The invention could be extended to illiterate people by customizing the medical image with some symbols that could be unique to the patient such as thumb impression and the patient can relate his medical image or report to that symbol.
The user input device 220 is configured to provide the patient preference on display of the medial image. In an embodiment, the patient's preference on customizing the medical image is obtained through the user input device. The user input collects the patient information, especially the language in which the patient information needs to be displayed on the medical image. Various user preferences may be collected, such as language, color, style or any other unique parameter that will help the patient to relate the medical image to the patient or to help the patient in identifying the image belonging to him. User input device 120 may collect the patient preference at the time of registration or while processing the image data. The user input device 120 may also assist the patient in selecting the patient identification parameter that need to be translated into patient's preferred language and to be incorporated into the medical image.
The user interface 130 is provided in association with the processing unit 110. The user interface 130 will assist the radiologist/technologist in selecting the preferred language. The patient may communicate the patient preferred language to the image processing system through the user input device 120. A radiologist/technologist may manually select the patient preferred language using the user interface 130. The selected language could be communicated to the processing unit 110. In an embodiment, a drop down menu having a list of languages may appear next to the patient's name. The user interface 130 may be used to select the patient preferred language by selecting one of the languages from the drop down menu. The user interface 130 could include graphical user interface and or other interfaces such as mouse, joystick, light pen, a touch screen and stylus, a keyboard with cursor keys, or combinations thereof.
In an embodiment, graphic tablet can be used as a medium to input the patient information. It can be stored as it is in the patient's handwriting and could be rendered on the medical image. The information which is in the patient's handwriting can be stored in a private tag.
In another embodiment, the user interface 130 may be a graphical user interface with a drop down menu, configured to assist the radiologist/technologist in manually selecting the patient identification parameter that need to be customized and displayed on the medical image. With reference to the input received from the user input device 120, the user interface 130 assists the radiologist/technologist in selecting the desired patient identification parameter and his preferred language.
In an embodiment, the patient identification parameter and his preferred language could be communicated automatically to the processing unit 110 and the processing unit 110 could translate the desired patient parameter into patient's preferred language and incorporate the same into the medical image.
The processing unit 110 has a translation module 115 and the translation module 115 translate the patient identification parameter or the identification information that need to be displayed in patient's preferred language. The processing unit 110 is configured to receive the patient identification information or the patient identification parameter and preferred language.
The processing unit 110 assists in displaying the medical image with the customized patient information on a display device 140. The display device 140 and the user interface 120 operate together to facilitate the radiologist/technologist to select patient's identification parameter or patient's preferred language. The display device 140 could be any monitor including a CRT display.
Dedicated hardware may be used instead of software and/or firmware for performing image processing, or a combination of dedicated hardware and software, or software in combination with a general purpose processor, or a digital signal processor may be used as the processing unit 110. Once the requirements for such software and/or hardware and/or dedicated hardware are gained from an understanding of the descriptions of embodiments of the invention contained herein, the choice of any particular implementation may be left to a hardware engineer and/or software engineer. However, any dedicated and/or special purpose hardware or special purpose processor is considered subsumed in the block labeled processor 110.
Whether a stand-alone workstation or an image processing system is used, software and/or firmware (hereinafter referred to generically as “software”) can be used to instruct the computer to perform the inventive combination of actions described herein. Portions of the software may have specific functions, and these portions are herein referred to as “modules” or “software modules.” However, in some embodiments, these modules may comprise one or more electronic hardware components or special-purpose hardware components that may be configured to perform the same purpose as the software module or to aid in the performance of the software module. Thus, a “module” may also refer to hardware or a combination of hardware and software performing a function.
The image processing system is further associated with a storage unit 150. The storage unit 150 could be a printer wherein the medical report or image film could be printed. The storage unit 150 could store the image or report in memory (ROM), random access memory (RAM), a miniature hard drive, a flash memory card, or any kind of device (or devices) configured to store instructions to a machine-readable medium or media.
In an embodiment, the patient preference could be obtained through voice recognition technique. The patient could orally communicate his preference and from that his preferred language could be interpreted/obtained.
In an embodiment, the patient identification information or the identification parameter may be displayed in patient's preferred language and in a common language, so that the clinician or reviewer does not have any problem in identifying the image correctly.
The medical image could include multimodality image such as X-ray system, Computer Tomography (CT) Imaging System, Magnetic Resonance Imaging System, Ultrasound Imaging System. It could include DICOM as well as non-DICOM images. Further the customization could be done to medical images including medical film and/or to medical reports.
In an embodiment, the image data 220 could be in the form of non-DICOM image data such as JPEG, PNG, MOV, MPEG etc. The image data 220 may have a header with patient information or the patient information could be provided along with the image data.
The image data 220 including the image information 222 and the patient identification information is fed to a processor 230. The processor 230 processes the image data 220 and generates medical images. The processor 230 is configured to include a translator 232 and a writer 234.
The user interface 240 is provided in association with the processing unit 110. The user interface 240 will assist the radiologist/technologist in selecting the preferred language. A radiologist/technologist may manually select the patient preferred language using the user interface 240. The selected language could be communicated to the processing unit 110.
Patient preferred language is communicated to the processor 230 and based on the patient input, desired language is selected using the user interface 240. In an embodiment, the user interface 240 could be a graphic interface wherein the image could be displayed and a list of options could be available for the radiologist/technologist/user/patient to select the patient's preferred language. The user interface 240 works in association with the processor 230. The translator 232 translates the patient identification information to the language selected by the radiologist/technologist through the user interface 240. The writer 234 incorporates the patient identification information in the translated language into the medical image. The patient identification information is incorporated into the image 220 such that it is visually detectable. Different techniques could be used to achieve this, and one example is layering technique. Once the patient identification information or parameter is incorporated in a visually detectable format, customized image 255, i.e the medical image with localized patient identification information is generated. The customized image 255 can be displayed on a display 250 before storing into different media.
