Description

TECHNICAL FIELD The present invention relates to a medical device. In particular, this invention relates to a system for determining the differential temperature in a breast, a sensor device, and a method for determining the differential temperature in a breast. BACKGROUND Several techniques have been used to monitor body temperature of a person. Accurate monitoring of body temperature is crucial in order to determine the health of a person. A condition of high body temperature might indicate the presence of an infection. In some cases, a differential body temperature (having different temperatures at regions of one body part) at a specific body part may indicate the presence of a lifethreatening disease. For example, the differential high temperature of a breast of a person indicates abnormalities in the breast of the person . As the abnormalities in the breast often produce additional heat through abnormal metabolic activity resulting in increased temperature of the breast. These abnormalities can lead to the development of potentially malignant tumour cells which can prove to be a fatal situation for the person. Several techniques are currently employed for the detection of malignant tumours in the beast in order to determine if the person's breast has been afflicted with cancer. Various techniques, include thermography, mammography, xerography, or the like. However, at the present, thermography is most widely used in medical diagnostics for the detection of breast cancer. Thermography is based on infra-red scanning of the surface of the breast and developing a thermogram which contains temperature information corresponding to the scanned surface. Since the temperature of malignant mammary tissues are usually higher than the temperature of normal tissues. However, this technique involves the use of expensive equipment and expert technicians or radiologists to analyse and interpret the thermogram. In addition to the thermogram, other simpler devices have also been used to check temperature of the breast at home with ease. However, these devices also pose some challenges to user as their results are needed to be visually examined by the user which might severely affect accuracy and authenticity of the result. Moreover, these devices are often faced with a problem of usability as they are operational at a specific temperature range. Thus, these devices may fail to provide accurate results when used outside the specific temperature range. Furthermore, other limitations offered by conventional devices are the absence of any check while using or reusing the device, which severely compromises the accuracy and consistency of results obtained using the conventional device. Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks associated with conventional systems and devices for monitoring the differential temperature of the breast of the user. SUMMARY OF THE INVENTION A first aspect of the invention provides a system for determining the differential temperature in a breast, the system comprising: at least one sensor device comprising - a base having a first side and a second side opposite to the first side, wherein the base has a hole; and - at least one temperature-sensitive element at least partially surrounding the hole, the at least one temperature-sensitive element being provided on the first side of the base, wherein when the at least one sensor device is in use, the first side is in contact with the breast of a user for a predefined time period and the at least one temperature-sensitive element senses temperatures of different regions of the breast; at least one camera configured to capture at least one image of the first side, wherein the at least one image is captured within a given time period from a time of removal of the first side from the breast; and at least one processor communicably coupled to the at least one camera, wherein the at least one processor is configured to: identify, in the at least one image, at least one image segment representing the at least one temperature-sensitive element; recognize pixel values of pixels in the at least one image segment; and determine the temperatures of different regions of the breast, based on the pixel values of pixels in the at least one image segment, wherein the temperatures of different regions of the breast form a differential temperature profile of the breast. The at least sensor device may be a wearable device. The at least one device is worn on the breast of the user to detect any potential abnormalities in the breast. The at least one sensor device functions by measuring the temperature difference of various regions of the breast to detect any potential abnormalities in that breast, some abnormalities can lead to, or already be, tumours or cancer tumours. It will be appreciated that teachings of the present disclosure are not limited to breast. However, the at least one sensor device of the present disclosure can be worn on any part of the body to detect any potential abnormalities based upon temperature in that region. The at least one sensor device can be worn on the breast of the user for a predefined time period. The predefined time period may lie in a range of 5 minutes to 30 minutes. The base has the first side and the second side. The second side is opposite to the first side. Furthermore, the base has the hole in order to wear the at least one sensor device appropriately on the breast. The hole could be in the middle of the base, on towards a given side of the base, on a corner of the base, and the like. The at least one temperature-sensitive element is provided surrounding the hole on the first side of the at least one sensor device. The first side, having the at least one temperature-sensitive element stays in contact with the user, when in use. The at least one temperature-sensitive element may include one large temperature-sensitive element or a plurality of small temperature-sensitive elements, depending upon the application of the at least one sensor device. The at least one temperature-sensitive element senses the temperatures of the different regions of the breast. The at least one camera could be a Red-Green-Blue (RGB) camera, a grayscale camera, or the like. The at least one camera captures the at least one image of the first side of the base. The at least one image is captured within the given time period upon removal of the at least one sensor device from the breast. The given time period may lie in a range of 0-15 minutes. The given time period is determined based upon the temperature-sensitive material used in the at least one sensor device. The given time period is determined such that a visual effect produced by the temperature-sensitive material does not get diminished and the at least one image of the first side is captured properly by the at least one camera to further interpret results of the at least one sensor device. In an example, the at least one image is captured within 2 minutes after removal of the at least one sensor device from the breast. Throughout the present disclosure, the term "processor" relates to a computational element that is operable to respond to and process instructions. The at least one processor, in operation, implements the method for determining the differential temperature in the breast. Furthermore, the term "processor" may refer to one or more individual processors, processing devices and various elements associated with a processing device that may be shared by other processing devices. Such processors, processing devices and elements may be arranged in various architectures for responding to and executing the steps of the method. The at least one processor is communicatively coupled to the at least one camera. For example, the at least one processor is communicatively coupled to the processor via a communication network. It will be appreciated that the communication network may be wired, wireless, or a combination thereof. The communication network could be an individual network or a combination of multiple networks. Examples of the communication network may include, but are not limited to one or more of, Internet, a local network (such as, a TCP / IP-based network, an Ethernet-based local area network, an Ethernet-based personal area network, a Wi-Fi network, and the like), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), a telecommunication network, and a short-range radio network (such as Bluetooth®). The at least one processor is configured to execute at least one software application for implementing at least one processing task that the at least one processor is configured for. The at least one software application could be a single software application or a plurality of software applications. The at least one software application is preferably implemented as application for a mobile device such as a smartphone. The at least one software application helps to interpret and read results of the at least one sensor device. The at least one processor receives the at least one image of the first side of the at least one sensor device. The at least one image could be received by the at least one processor as a video, an image, a live stream, and the like. Preferably, the at least one image is received by the at least one processor via the communication network. The at least one processor identifies, the at least one image segment representing the at least one temperaturesensitive element of the at least one sensor device, in the at least one image. The at least one processor identifies the at least one image segment by employing at least one image processing algorithm. Optionally, a given image processing algorithm is an object identification algorithm, a feature detection algorithm, and the like. Post identification of the at least one image segment, the at least one processor is configured to recognize pixel values of pixels in the at least one image segment. The term "pixel value" of a pixel refers to colour information represented by the pixel. The colour information may be expressed as Red-Green-Blue (RGB) colour component values, grayscale values, or similar. The Red-Green-Blue (RGB) colour component values of a given colour component in the at least one image segment may lie in a range of 0-256. The grayscale values of the at least one image segment may lie in a range of 0-1. Furthermore, the at least one processor determines the temperatures of different regions of the breast. The at least one image have pixels of varying pixel values. Each of the pixel values of the at least one image determines the corresponding temperature of the breast. In an example, the at least one image segment may have three regions of varying colours, wherein for example, a first region may have an orange colour (243, 203, 23), a second region may have a pink colour (243, 122, 124) and a third region may have a yellow colour (243, 214, 10). Among these three regions, the region having the orange colour may be the region with a highest temperature, the region having the yellow may be the region with a lowest temperature amongst the three regions. In another example, the at least one image segment may have three regions. A first region may have a pixel value of 0.2, a second region may have a pixel value of 0.24 and a third region may have a pixel value of 0.8. Amongst three regions, the third region may be the region having the highest temperature indicating a potential abnormality in the corresponding region of the breast. It will be appreciated that the at least one camera, communicably coupled to at least one processor, that is able to execute a software application could be embodied through a singular device, for example, a user's camera smartphone and the like. In this regard, when the at least one sensor device is worn by the user, the at least one temperature-sensitive element senses the temperatures of different regions of the breast with the help of a temperaturesensitive material provided on the at least one temperature-sensitive material. The temperature-sensitive material may undergo colour transformation depending upon varying temperatures across regions of the breast. As an example, the temperature-sensitive material may turn its colour from a blue colour to a pink colour as the temperature rises across the breast. As another example, the temperature-sensitive material may turn its state from solid to liquid. Therefore, the at least one image of the at least one temperature-sensitive element has varying colours across the at least one image segment. Therefore, the at least one processer is able to determine temperatures of different regions of the breast by analysing the pixel values of pixels of the at least one image segment. The temperatures of different regions of the breast form the differential temperature profile of the breast. To increase the accuracy of the at least one sensor device, the user is instructed to avoid using the at least one sensor in a heated condition of the body, such as after exercise, after sunbath, or the like. The system as disclosed above provides a diagnostic kit to check for abnormalities in the breast of the user by determining differential temperatures in the breast. The system of the present disclosure is an early diagnostics medical system that is safe, reliable, economical, accurate, and easier to use than conventional systems. The system is effectively used to routinely monitor for breast abnormalities and is intended to be used as an adjunct to other procedures, including established procedures, for the detection of breast diseases, such as clinical breast examination and mammography. The system can be efficiently used for users of all ages. The system for determining the differential temperature in a breast is technically superior to other conventional systems. The present system uses the software application to measure the differential temperature of the breast. The system can position temperature from the breast effectively to the software application. The software application significantly increases the accuracy and consistency of measurement obtained using the at least one sensor device and provides an interactive and / or easy platform for the user to view results. Optionally, the at least one processor may be further configured to: for each region amongst the different regions of the breast, determine whether a temperature of said region exceeds a predefined temperature threshold value; and generate a thermal map of the breast based on the differential temperature profile of the breast, wherein the thermal map indicates any region whose temperature exceeds the predefined temperature threshold value. When the temperature of the said region exceeds a predefined temperature threshold value, that may indicate said region could potentially have an abnormality. The presence of the abnormality in the breast often results in additional heat generation through abnormal metabolic activity, therefore, a change in the temperature of the breast could mark the presence of potential abnormality in the breast. The temperature threshold value could lie in a range of 35 degrees Celsius to 38 degrees Celsius. The temperature threshold value lies in a range of 35 degrees Celsius to 36 degrees Celsius, 35 degrees Celsius to 37 degrees Celsius, 35 degrees Celsius to 38 degrees Celsius, 35.5 degrees Celsius to 36.5 degrees Celsius, 35.5 degrees Celsius to 37 degrees Celsius, 35.5 to 37.5 degrees Celsius, 36 degrees Celsius to 37 degrees Celsius, 36 degrees Celsius to 38 degrees Celsius, 36.5 degrees Celsius 37.5 degrees Celsius, 36.5 degrees Celsius to 38 degrees Celsius, or similar. Further, the at least one processor generates a thermal map based upon the differential temperature profile of the breast. The thermal map is a representation of the temperature profile of different regions of the breast having temperature exceeding the predefined temperature threshold value. Optionally, the thermal map is at least one of: a colour map, a grayscale map, or the like. As an example, the thermal map may have three regions. Two regions out of the three regions may have a same colour, say for example, a blue colour, and a third region may have a yellow colour. Therefore, the region of the thermal map having the yellow colour may indicate abnormality in the corresponding region of the breast. Advantageously, the technical benefit of this is that the results of the at least one sensor device that are generated in form of the thermal map, can be accurately read and understood by the user. Optionally, the system may further comprise an infrared temperature measurement device configured to measure test temperatures of different regions of the breast, and wherein the at least one processor is further configured to receive the test temperatures of different regions of the breast from the infrared temperature measurement device. The infrared temperature measurement device is communicatively coupled to the at least one processor via the communication network, The test temperatures measured by the infrared temperature measurement device are received by the processor via the communication network. The test temperatures are measured using infrared radiation (for example, radiation having a wavelength lying in a range of 0.7 micrometres to 1000 micrometres) in a contactless manner. The infrared radiation is not visible to the human eye. Operation of infrared temperature measurement devices is well known in the art. Optionally, upon receiving the test temperatures of different regions of the breast from the infrared temperature measurement device, the at least one processor is further configured to compare the test temperatures of different regions of the breast with the temperatures of different regions of the breast that are determined based on the pixel values, to validate the differential temperature profile of the breast. The infrared temperature measurement device could be implemented in combination with at least one camera or as a part of the at least one camera. The infrared temperature measurement device could be implemented as a measuring device capable of safely measuring temperature of the part of the body of the user with ease. For example, the infrared temperature measurement device may be a measuring device (such as an infrared thermometer) which can be used to measure the temperature in a contactless manner. The technical benefit of using the test temperatures is that the results obtained by the system using the at least one sensor device can be accurately validated by the infrared temperature measurement device, thereby increasing efficiency and authenticity of the results obtained by the system. Optionally, the system may further comprise at least one user device communicably coupled to the at least one processor, wherein the at least one processor is further configured to send, to the at least one user device, at least one of: the temperatures of different regions of the breast, a thermal map of the breast, test temperatures of different regions of the breast, for presentation at the at least one user device. The at least one user device has a display. A user interface (UI) is rendered on the display in order to view results, such that the user can easily and accurately view the results. Examples of a given user device include, but are not limited to, a smartphone, a smartwatch, a tablet computer, a laptop computer, a desktop computer, an infotainment device, and a personal digital assistant. The at least one processor is communicatively coupled to the at least one user device via the communication network. The at least one processor sends the temperatures of the different regions of the breast to the user device. At the UI rendered on the display of the at least one user device, the temperatures of the different regions of the breast may be visually represented in form of one or more of a table, a histogram, a schematic, a heat map, and the like. Further, the at least one processor sends thermal map and the test temperatures measured by the infrared temperature measurement device to the user device. Optionally, the at least one user device comprises the at least one camera. For example, a mobile phone equipped with camera can be used to read the temperatures of different regions of the breast by taking a picture of the first side of the base of the at least one sensor device using the camera as well as view the temperatures determined upon processing. A processor of the at least one user device may be employed for the processing. In such a case, a single user device may be beneficially used for implementing the camera as well as the at least one processor of the system. The technical advantage of this is that the results obtained by the system can be efficiently captured and viewed using the at least one user device making the system of the present disclosure very compact and easy to use. Optionally, the at least one sensor device may comprise a unique identifier provided on the base, the at least one camera being configured to capture at least one identification image representing the unique identifier, wherein the at least processor is configured to: identify the unique identifier in the at least one identification image; associate the temperatures of different regions of the breast that are determined to the unique identifier; and perform one of: block future interpretation of sensed temperatures from the at least one sensor device, permit future interpretation of sensed temperatures from the at least one sensor device upon successful reuse actions being implemented. The at least one unique identifier could be provided on either the first side or the second side of the base. As an example, the unique identifier may be provided on the first side of the base. The unique identifier could be any of a quick response (QR) code, an alphanumeric code, an Radio Frequency Identification (RFID) marker, a noise pattern, and the like. The at least one camera captures the at least one identification image. The at least one identification image includes the one unique identifier. The at least one identification image is received by the at least one processor via the communication network. The at least one processor identifies the at least one identification image using at least one feature recognition algorithm. Further, the at least one processor associates the unique identifier on the at least one sensor device with the temperatures of different regions of the breast determined using the at least one sensor device. Optionally, the at least one processor also records uses of the unique identifier which is essential to determine uses of the at least one sensor device. Optionally, the unique identifier could also be used to ensure a condition of the at least one sensor device prior to use. For example, the unique identifier may be used to ensure the at least one device is working properly. Furthermore, the at least one processor may be configured to block future interpretation of the sensed temperatures from the at least one sensor device. The at least one processor can only interpret temperatures of different regions of the breast which are associated with the unique identifier. Further, the at least one processor permits future interpretation of sensed temperatures from the at least one sensor device upon successful reuse actions being performed. The reuse could be performed by the user, for example, after a reuse action of replacing the unique identifier with another one. The at least one processor may associate the sensed data with a new unique identifier and allow interpretation of the temperatures. Optionally, the at least one processor allows reuse of the at least one sensor device only after a reuse action of a predefined check or confirmations is / are made by the user. In this regard, the at least one processor could prompt the user to provide some inputs values in order to enable another use of the at least one sensor device. As an example, the input value may be an ambient temperature of a place where the at least one sensor is being used. In case, the ambient temperature is less than 25 degrees Celsius, reuse may be permitted owing to fewer chances of sweating. As another example, the input value may be the sensed temperature of a previous test. In case, the previous temperatures of any region of the breast are not above the temperature threshold value, the reuse may be allowed, as the at least one temperature-sensitive element will not impact the accuracy of future detection of temperatures. The technical benefit of this is that the unique identifier on the at least one sensor device is associated with the measurement obtained using the at least one sensor device. The association of the measurements with the unique identifier prevents future interpretation using the at least one sensor device, thereby solving the problem of multiple uses of conventional systems. The multiple uses might significantly decrease the accuracy of the results. Therefore, the at least one sensor device is restricted to single use only until certain checks are provided by the user. Owing to the above, the accuracy of the system is significantly improved. Optionally, the at least one camera is configured to capture at least one body image representing at least the breast of the user, wherein the at least one processor is further configured to: identify features of the breast that are represented in the at least one body image; digitally superimpose at least one virtual object on the at least one body image for enabling correct placement of the at least one sensor device on the breast; and send the at least one body image having the at least one virtual object superimposed thereon to a user device for display thereat. Optionally, the user device is associated with a user. Examples of the user device include, but are not limited to, a mobile phone, a computer, a laptop, and a smartwatch. The features could be edges, shapes, size, colour of different regions, or the like. Optionally, the at least one processor is configured to identify the features of the breast that are represented in the at least one body image using at least one feature detection algorithm. Optionally, a given feature detection algorithm is at least one of: an edge-detection algorithm, corner-detection algorithm, a blob-detection algorithm, a feature descriptor algorithm. Further, at least one processor is configured to digitally superimpose the virtual object on the different regions of the at least one body image, as required. The virtual object is a computer-generated object used to indicate different features of the breast that are represented in the at least one body image. The virtual object could be a geometric shape, an arrow, a pattern, or similar, that enables in correct placement of the at least one sensor device on the breast. As an example, the virtual object may be the arrow pointing towards a nipple region of the breast. As another example, the virtual object may be a circle encircling an outer region of the breast. The at least one body image superimposed with the virtual object is an augmented reality image. Further, the at least one processor sends the at least one augmented reality image to the user device in order to be displayed to the user. The technical benefit of this is that the augmented reality image is utilized to provide accurate positioning of the at least one sensor device on the breast of the user thereby improving the efficiency and accuracy of the results. Optionally, the at least one sensor device may comprise a first sensor device and a second sensor device, wherein the first sensor device is used for determining first temperatures of different regions of a left breast of the user and the second sensor device is used for determining second temperatures of different regions of a right breast of the user, and wherein the at least one processor is configured to: for a given region of the breast, compare its corresponding first temperature and second temperature to determine a temperature difference therebetween. Optionally, the at least one processor is further configured to determine whether the temperature difference exceeds a predefined difference. Optionally, when for the given region of the breast, the temperature difference exceeds the predefined difference, the at least one processor is configured to indicate a possibility of an abnormality being present. The predefined difference could lie in a range of 0.5 to 2.5 degrees Celsius. The predefined difference could lie in a range of 0.5 to 1 degrees Celsius, 0.5 to 1.5 degrees Celsius, 0.5 to 2 degrees Celsius, 0.75 to 1.5 degrees Celsius, 0.75 to 2 degrees Celsius, 0.75 to 2.5 degrees Celsius, 1 to 1.5 degrees Celsius, 1 to 2 degrees Celsius, 1.5 to 2 degrees Celsius, 1.5 to 2.5 degrees Celsius or similar. In an example, the temperature difference between two regions of each of the breast may be equal to or greater than 2 degrees Celsius, may relate to a condition of abnormality in the breasts. The technical benefit of this is that the at least one sensor device is able to detect the abnormality accurately. A second aspect of the present disclosure provides a sensor device comprising: a base having a first side and a second side opposite to the first side, wherein the at least one base has a hole; and at least one temperature-sensitive element surrounding the hole, the at least one temperature-sensitive element being provided on the first side of the base, wherein when the sensor device is in use, the first side is in contact with the breast of a user for a predefined time period and the at least one temperature-sensitive element senses temperatures of different regions of the breast.
