TECHNICAL FIELD

[00Θ21 The subject matter disclosed herein relates to a medical imaging system and a portable detector control device for image acquisition. More specifically, relates to a portable detector control device capable of communicating with multiple image detectors for image acquisition.

BACKGROUND OF THE INVENTION

[0003] The emergence of different medical imaging systems has brought enhanced workflow and high image quality to medical imaging. However, many of the earlier radiographic imaging systems employ conventional X-ray imaging using film and/or computed radiography. In order to obtain images from these systems, the imaging medium must be transported and processed after each exposure, resulting in a time delay in obtaining the desired images. A subject whose image has been taken may need to wait for a long time in a medical center so as to confirm the image and do another exposure if needed. This led to the advent of digital radiography that provides an alternative solution allowing acquisition of image data and reconstructed images on the spot for quicker viewing and diagnosis, and allows for images to be readily stored and transmitted to consulting and referring physicians and specialists. However, the cost of replacing the earlier conventional imagining systems with digital imaging systems may be imposing to a hospital or a tertiary care medical center. Hence, there is a need to retrofit the earlier imaging systems for digital imaging in a cost effective manner involving as few components of the systems as possible.

DETAILED DESCRIPTION OF THE INVENTION

[0018] In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific embodiments that may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments, and it is to be understood that other embodiments may be utilized and that logical, mechanical, electrical and other changes may be made without departing from the scope of the embodiments. The following detailed description is, therefore, not to be taken as limiting the scope of the invention.

[0019] As discussed in detail below, embodiments of the invention including a medical imaging system for image acquisition is disclosed. The medical imaging system includes an imaging source, and a source controller coupled to the imaging source and configured to command emission for image exposures. An imaging detector in the medical imaging system is configured to acquire the image data without communication from the source controller. A portable detector control device is configured to identify the imaging detector within the vicinity when the portable detector control device boots up. Subsequently it is determined whether the imaging detector is associated with the portable detector control device and then communicates with the imaging detector if associated.

[0020] Referring generally to FIG. 1 schematically illustrating a perspective view of an exemplary medical imaging system 100 such as an X-ray imaging system in accordance with an embodiment. In the illustrated embodiment, the medical imaging system 100 as adapted is a digital X-ray imaging system. The medical imaging system 100 is designed both to acquire image data and to process the image data for display in accordance with the present technique. Throughout the following discussion, however, while basic and background information is provided on the digital X-ray imaging system used in medical diagnostic applications, it should be born in mind that aspects of the present techniques may be applied to digital detectors, including digital X-ray detectors, used in different settings (e.g., projection X-ray, computed tomography imaging, tomosynthesis imaging, etc.) and for different purposes (e.g., parcel, baggage, vehicle and part inspection, etc.).

[00211 Ϊ^{Ω tne} embodiment illustrated in FIG. 1, the medical imaging system 100 includes an X-ray imaging system 102. The X-ray imaging system 102 may be a conventional analog X-ray imaging system, retrofitted for digital image data acquisition and processing as described below. In one embodiment, the X-ray imaging system 102 may be a stationary system disposed in a fixed imaging room, such as that generally depicted in and described below with respect to FIG. 1. It will be appreciated, however, that the presently disclosed techniques may also be employed with other imaging systems, including mobile X-ray imaging systems in other embodiments. The X-ray imaging system 102 includes an overhead tube support arm 104 for positioning an imaging source 106, such as an X-ray source, and a collimator 108 with respect to a subject or patient 1 10 and an imaging detector 112. The imaging detector 112 may be a digital X-ray detector. In some embodiments, the imaging detector 1 12 may be selected from a plurality of imaging detectors 1 12, represented by an imaging detector 1 14, from a docking station 1 16 (e.g., charging docking station). Each imaging detector 1 12 of the plurality of imaging detectors 1 12 may be labeled and designed for a particular type of imaging (e.g., fluoroscopic and radiographic imaging). The imaging detector 1 12 is configured to acquire X-ray image data without communication from a controller of the imaging source 106. In other words, the imaging detector 1 12 is without communication of timing signals from the controller of the source 106 as to an X-ray exposure. As a result, in preparation for acquiring X-ray image data the imaging detector 1 12 is configured to continuously sample data prior to and during an X-ray exposure. Also, the imaging detector 1 12 is configured to combine multiple frames that include imaging data to generate X~ray images. In addition, the imaging detector 1 12 is configured to at least partially process X-ray image data.

(0022] In one embodiment, the imaging system 102 may be used in consort with one or both of a patient table 1 18 and a wall stand 120 to facilitate image acquisition.

Particularly, the table 1 18 and the wall stand 120 may be configured to receive the imaging detector 1 12. For instance, the imaging detector 1 12 may be placed on an upper, lower or intermediate surface of the table 1 18, and the patient 1 10 (more specifically, an anatomy of interest of the patient 1 10) may be positioned on the table 1 18 between the imaging detector 1 12 and the imaging source 106. Also, the wall stand 120 may include a receiving structure 122 also adapted to receive the imaging detector 1 12, and the patient 1 10 may be positioned adjacent the wall stand 120 to enable the image data to be acquired via the imaging detector 1 12. The receiving structure 122 may be moved vertically along the wall stand 120.

(0023 j Also depicted in FIG. 1 , the imaging system 102 includes a workstation 124, display 126, and printer 128. In one embodiment, the workstation 124 may include or provide the functionality of the imaging system 102 such that an operator or user 130, by interacting with the workstation 124 may control operation of the source 106 and imaging detector 1 12. In other embodiments, the functions of the imaging system 102 may be decentralized, such that some functions of the imaging system 102 are performed at the workstation 124 (e.g., controlling operation of the source 106, while other functions (e.g., controlling operation of the imaging detector 1 12) are performed by another component of the imaging system 102, such as a portable detector control device 1 2. The portable detector control device 132 may be a mobile device, a personal digital assistant (PDA), a palmtop computer, a laptop computer, a smart telephone, a tablet computer, or any suitable general purpose or a dedicated portable interface device. The portable detector control device 132 is configured to be held by the user 130 and to communicate wirelessly with the imaging detector 1 12, It is noted that the imaging detector 1 12 and the portable detector control device 132 may utilize any suitable wireless communication protocol, such as an IEEE 802.15.4 protocol, an ultra-wideband (UWB) communication standard, a Bluetooth® communication standard, or any IEEE 802.1 1 communication standard. Alternatively, the portable detector control device 132 may be configured to be tethered or detachably tethered to the imaging detector 112 to communicate via a wired connection.

[0Θ24] The portable detector control device 132 is also configured to communicate instructions (e.g., detector operating mode) to the imaging detector 1 12 for the acquisition of X-ray image data, in turn, the imaging detector 1 12 is configured to prepare for an X-ray exposure in response to instructions from the portable detector control device 132, and to transmit a detector ready signal to the portable detector control device 132 indicating that the imaging detector 1 12 is prepared to receive the X-ray exposure. The portable detector control device 132 may also be configured to

communicate patient information or X-ray technique information to the imaging detector 1 12. Similar to the imaging detector 1 12, the device 132 may be without communication from the controller of the radiation source 106. Further, the portable detector control device 132 is configured to receive X-ray image data from the imaging detector 1 12 for processing and image reconstruction. Indeed, both the imaging detector 1 12 and the portable detector control device 132 are configured to at least partially process the X-ray image data. However, in certain embodiments, the imaging detector 112 and/or the portable detector control device 132 are configured to fully process the X-ray image data. Also, the imaging detector 1 2 and/or the portable detector control device 132 is configured to generate a DICOM compliant data file based upon the X-ray image data, patient information, and other information. Further, the imaging detector 1 12 and/or the portable detector control device 132 is configured to wirelessly transmit (or via a wired connection) processed X-ray image data (e.g., partially or fully processed X-ray image data) to an institution storage system over a network 34. The institution storage system may include but not limited to a hospital information system (HIS), a radiology information system (RSS), and/or picture archiving communication system (PACS). In some embodiments, the institution storage system may process the X-ray image data. In one embodiment, the workstation 124 may be configured to function as a server of instructions and/or content on the network 134 of the medical facility. The imaging detector 1 12 and/or portable detector control device 132 are also configured to transmit, via a wired or wireless connection, processed X-ray images to the printer 128 to generate a copy of the image.

[0025] The portable detector control device 132 includes a user-viewable screen 136 and is configured to display patient data and reconstructed X-ray images based upon X- ray image data on the screen 136, The screen 136 may include a touch-screen and/or input device (e.g., keyboard) configured to input data (e.g., patient data) and/or commands (e.g., to the detector). For example, the portable detector control device 132 may be used to input patient information and other imaging related information (e.g., type of source 106, imaging parameters, etc.) to form a DICOM image header. In one embodiment, the patient information may be transferred from a patient database via a wireless or wired connection from the network or the workstation 124 to the portable detector control device 132. The imaging detector 1 2 and/or the portable detector control device 132 may incorporate the information for the image header with the X-ray- image to generate the DICOM compliant data file. Also, the portable detector control device 132 may be used to navigate X-ray images displayed on the screen 136, Further, the portable detector control device 132 may be used to modify the X-ray images, for example, by adding position markers (e.g., "L"/ "R" for left and right, respectively) onto the image. In one embodiment, metal markers may be placed on the imaging detector 1 12 to generate position markers.

[0026] FIG. 2 is a schematic illustration of the portable detector control device 132 capable of communicating with multiple medical imaging systems such as an X-ray imaging system 200 and an X-ray imaging system 202 in more detail. The X-ray imaging system 200 includes the imaging source 106 positioned adjacent to a collimator 108 and connected to a support arm 204. The collimator 1.08 permits a stream of radiation to pass into a region in which a subject 206, such as a human patient is positioned. The subject 206 is present on a table 208. A portion of the radiation passes through or around the subject 206 and impacts the imaging detector 1 12. As described in more detail below, the imaging detector 1 12 converts the X~ray photons received on its surface to lower energy photons, and subsequently to electric signals which are acquired and processed to reconstruct an image of the features within the subject 206.

[ΘΘ27] The X-ray imaging system 200 is coupled to a power supply 210 which furnishes power for examination sequences. The X-ray imaging system 200 and the power supply 210 are coupled to a source controller 212 configured to command X-ray emission of X-rays for image exposures. As mentioned above, the imaging detector 1 12 is configured to acquire X-ray image data with or without communication from the source controller 212. In an. embodiment the imaging detector 1 12 is responsive to the portable detector control device 132 configured to communicate instructions the imaging detector 1 12 for acquisition of the X-ray image data. The portable detector control device 132 is configured to receive the X-ray image data from the imaging detector 1 12 for processing and imaging reconstruction. Further the X-ray imaging system 200 also includes a display 126 and a control unit 214. The X-ray imaging system 200 is capable of moving to different places using wheels present in a base unit 216. Thus the X-ray- imaging system 200 may be a mobile X-ray imaging system.

[Θ028] The portable detector control device 132 also communicates with other medical imaging systems present in the same location or vicinity for example the X-ray imaging system 202. The X-ray imaging system 202 may be functionally and structurally similar to the X~ray imaging system 200 and hence the components of this system are same as the X-ray imaging system 200. Once the exposure of an anatomy of the subject 206 is completed then the portable detector control device 132 may connect with the X~ ray imaging system 202 to start the exposure of an anatomy of a subject 218.

[0Θ29] FIG, 3 is a schematic illustration of functional components of the portable detector control device 132 communicating with the imaging detector 1 12 in accordance with an embodiment. FIG. 4 is a schematic illustration of the portable detector control device of FIG. 3. FIG. 5 illustrates a communication flow between the imaging detector, the portable detector control device and an operator or user in accordance with an embodiment. . FIG. 3, FIG. 4 and FIG. 5 are hereinafter described together. An imaging detector may need to be associated with the portable detector control device 132 in order to establish a communication. The portable detector control device 32 may store a list or a database of associated imaging detectors in a memory 300. The list may include identifier and configuration information of each associated imaging detector. These associated imaging detectors may be compatible to communicate and operate with the portable detector control device 132. Hence any other imaging detectors attempting to connect with the portable detector control device 132 may not be able to connect as they are not associated.

| 003 | When the portable detector control device 132 is within the vicinity of imaging detectors in a medical imaging environment and boots up as shown by a region 302 in FIG. 5, then a processor 304 searches for one or more imaging detectors for connection. The image detectors also need to be booted up for connection. The processor 304 identifies the imaging detector 1 12 as associated with the portable detector control device 132, and the imaging detector 1 12 boots up as shown by a region 306 in FIG. 5. This is performed by comparing identifier and configuration information of the imaging detector 1 12 with identifier and configuration information of the associated imaging detectors. In an embodiment the list of associated imaging detectors may include a primary imaging detector as illustrated in FIG. 4. The portable detector control device 132 may establish connection with the primary imaging detector for the first instance or the preference may he for the primary imaging detector amongst the other imaging detectors. The list may also include a secondary imaging detector that may be a second preference of the portable detector control device 132, The imaging detectors may he sorted in the form of their order of preference in the list or the database.

{0031] in an embodiment the imaging detector 112 may publish its status information and be received by the portable detector control device 132 as indicated by an arrow 308. The processor 304 may receive status information from all the imaging detectors. The status information may indicate a currents status for example, ready for examination, idle, booting up, booted, under examination associated with an imaging detector. The imaging detector 112 currently communicating with the portable detector control device 132 may be a primary imaging detector. The portable detector control device 132 may

communicate with the imaging detector 3 12 using a communication interface 31.0. The communication interface 310 may be based on communication protocols such as but not limited to IEEE 802.15.4 protocol, an ultra-wideband (UWB) communication standard, a Bluetooth® communication standard, or any ΪΕΕΕ 802, 1 1 communication standard. The portable detector control device 132 also includes a control circuitry 312 that controls the functioning of the device. When the communication with the imaging detector 1 12 is completed or suspended the portable detector control device 132 may perform a search to connect with an imaging detector 314 stored as a secondary imaging detector as shown in FIG. 4. As the primary imaging detector is not connected with the portable detector control device 132 then a second preference, i.e., the imaging detector 314 is considered for connection, it may be contemplated that these imaging detectors may be arranged in any other configuration or order for connecting with the portable detector control device 132. This is further explained in conjunction with FIG. 6.

[0032} Referring back now to the communication between the imaging detector 1 12 and the portable detector control device 132, the imaging detector 112 and the portable detector control device 132 may be in a ready for exam status as indicated by a region 316 and a region 31 8 respectively. The processor 304 instructs the imaging detector 112

.1 ! to start an examination process as indicated by a region 320 and a region 322. This process may be initiated based on user input (i.e., an input from an operator or user 324), The examination process involves capturing one or more images of an anatomy of a subject. The processor 304 assigns a unique identifier 326 for this examination process and communicates to the imaging detector 1 12 as indicated by an arrow 328. The imaging detector 112 receives the unique identifier 326. The processor 304 may also communicate an identifier associated with the portable detector control device 132 to the imaging detector 112 depicted by the arrow 328. in an instance the imaging detector 1 12 may be configured to store the identifier and compare with a database of identifiers of associated portable detector control devices. This database may be stored in a memory of the imaging detector 1 12. The processor 304 may also query for the patient information trom the user. The patient information received may be stored on the memory 300, In an embodiment the processor 304 may be configured to initiate the examination process without the patient information. Such examination process may happen during emergency situations.

[0033J Now in order to perform the examination process appropriate imaging protocols may need to be selected. To this end, the processor 304 may present multiple imaging protocols to a user i.e., the operator 324. An imaging protocol may indicate a type of imaging, an anatomy to be examined, recommended settings for image exposure and a type of examination study that needs to be performed. The operator 324 selects an imaging protocol as indicated by an arrow 330 and subsequently the processor 304 sends instructions to the imaging detector 1 12 for image exposure. The processor 304 may also present recommended settings for the image exposure based on the selected imaging protocol to the user. The user may modify the settings based on the need. Once the settings are finalized the processor 304 may send calibration data to the imaging detector 1 12 for calibrating the imaging detector before initiating the image exposure indicated by an arrow 332. The calibration data may be specific for the imaging detector 1 12 or a room where the subject and the medical imaging system are placed or a combination of both. The imaging detector 1 12 then captures one or more images of the anatomy of the subject upon exposure. The one or more images are then transmitted to the portable detector control device 132 along with the unique identifier associated with the examination process by the imaging detector 1 12 depicted by an arrow 334. in addition the imaging detector 1 12 may assign an image identifier for each image generated and thus the image identifier may he also transmitted along with the images, in an

embodiment an image identifier may be added to an image of the anatomy as a tag.

However it may be contemplated that the image identifier may be added to the image using any other techniques,

|ΘΘ34] The processor 304 may compose one or more captured images and present a preview of these images to the user indicated by an arrow 336. The user may examine and confirm the images that are acceptable based on the suggested examination process. If some images are not acceptable then the user rejects these images. Consequently the processor 304 may instruct the imaging detector 1 12 in case more images need to be captured. When the images are confirmed, the processor 304 may send instructions for closing the examination process to the imaging detector 1 12 as indicated by an arrow 338. During a close exam stage (indicated by a region 340 and a region 342) the imaging detector 1 12 may send back information associated with the portable detector control device 132 (for example the unique identifier) to the processor 304. Thereafter the processor 304 may instruct, the imaging detector 1 12 for performing another examination process by communicating a new unique identifier. Once the examination process is closed the imaging detector 112 and the portable detector control device 132 may move into an idle mode as indicated by a region 344 and a region 346. The portable detector control device 132 may be in the idle mode if it is not communicating with any other imaging detectors. Further in case the communication between the portable detector control device 132 and the imaging detector 1 12 gets suspended, the imaging detector 1 12 may store the captured images in a memory. The imaging detector 1 12 in this event may also remove or send back the information associated with the portable detector control device 132 as indicated by an arrow 348. Then when the portable detector control device 132 reconnects with the imaging detector 112, the removed unique identifier may be send again to the imaging detector 1 12. The imaging detector 112 retrieves the captured images based on the received unique identifier and transfers them to the portable detector control device 132 for preview and confirmation.

[00351 The confirmed images may need to be transferred to a storage system by the processor 304. The storage system may be but not limited to a PACS 350 and a storage device 352. The confirmed images may be transmitted to the storage system over a network such as the network 134. In an embodiment prior to transfer the confirmed images may be annotated with patient information associated with the subject, i.e., patient. The patient information may include for example name, age, sex, and health history. For example, the patient information may be tagged with an image. Moreover the confirmed images may be also annotated with other information such as, hospital or medical center information. In another instance the patient information and the other information may be appended in a header of the image. This information facilitates in retrieving the images in a convenient manner from the storage system for future use. The annotated images may also be sent to a printing device and a storage device of the printing device by the processor 304. The processor 304 may be capable of

preprocessing an annotated image. The preprocessing process may include but not limited to cropping, adding position markers, and other enhancement techniques that may be applied on the annotated image.

[0036] in an embodiment the processor 304 may be configured to override a communication link between another portable detector control device and the imaging detector 1 12. For instance when the imaging detector 1 12 is initially communicating with a first portable detector control device and the portable detector control device 132 may attempt to communicate with the imaging detector 1 12. Then the portable detector control device 132 may be able to override the connection between the imaging detector 1 12 and the first portable detector control device when the connection is in an idle or suspended state. This is explained below in conjunction with FIG. 6. Moreover in an embodiment the processor 304 may be configured to send instructions to the imaging detector 1 12 to stay in a sleep mode and an active mode. [0037] FIG. 6 is a schematic illustration of an exemplary environment 600 where a portable detector control device 132 and a portable detector control device 602 communicates with multiple imaging detectors in accordance with an embodiment. In the exemplary environment 600, two medical imaging systems such as an X-ray imaging system 604 and an X-ray imaging system 606. The X-ray imaging system 604 may include an imaging detector 608 and the X-ray imaging system 606 may include an imaging detector 610. When the portable detector control device 132 boots up, it receives status information from both imaging detectors. The portable detector control device 132 starts communication with the imaging detector 608 which is the primary imaging detector and initiates an examination process. The portable detector control device 602 may enter the location where the imaging detector 608 and the imaging detector 610 are present or near their vicinity and attempt to communicate with one of them. The device 602 also receives status information from both the imaging detectors. In an instance the portable detector control device 602 may try to connect with the imaging detector 608 and the portable detector control device 132 may be intimated of this connection attempt. The portable detector control device 132 may allow the device 602 to override the connection if it is not communicating with the imaging detector 608, i.e., the imaging detector 608 is in an idle mode. However if the communication between the portable detector control device 132 and the imaging detector 608 is active then the device 602 is not allowed to override the connection. Then the device 602 may need to check if it needs to connect with any other imaging detectors for example, the imaging detector 610.

[0038] Besides in certain instances the portable detector control device 132 may move beyond the vicinity or a wireless coverage area of the imaging detector 608 thereby leading to an interruption in the communication. The imaging detector 608 may store any captured images associated with the examination process in its memory and remove information associated with the device 132. In an embodiment the imaging detector 608 may remove the information and store the captured images after a threshold time period elapses. In this occasion the device 602 may connect with the imaging detector 608 and perform any other imaging operation. When the device 132 comes back and reconnects

IS with imaging detector 608 the captured images may be send to the device 132. In order to reconnect and receive the captured images the device 132 needs to send a unique identifier associated with the examination process to correlate the captured images with the unique identifier.

[0039J FIG. 7 illustrates a flow diagram of a method 700 of managing a plurality of imaging detectors for imaging of subjects in a medical imaging environment in accordance with an embodiment. The medical imaging environment includes the plurality of imaging detectors capable of communicating with a plurality of portable detector control devices. Each portable detector control device searches for multiple imaging detectors in its vicinity at step 702 once they boot up. The portable detector control device and the imaging detectors may boot up at different instances, i.e., not at the same time. The imaging detectors may publish their status information to all the portable detector control devices. Based on the status information, the portable detector control device communicates with an imaging detector associated with the portable detector control device. The portable detector control device stores the database of associated imaging detectors. The portable detector control device compares all the imaging detectors with the associated imaging detectors stored in the database.

[0040] The portable detector control device identifies an imaging detector with which it may communicate at step 704. The imaging detector identified may be associated with the portable detector control device. Thereafter at step 706 a

communication link between the portable detector control device and the identified imaging detector is established. The portable detector control device instructs the imaging detector to perform imaging of a subject. The image of an anatomy of the subject may be transferred to the portable detector control device to be presented to a user. The user sees the preview of the image in the portable detector control device and confirm the image if it satisfies the needs.

[0041] Turning now to FIG. 8 illustrating a flow diagram of a method 800 of managing the plurality of imaging detectors for imaging of subjects in the medical imaging environment in accordance with another embodiment. Each portable detector control device searches for multiple imaging detectors in its vicinity at step 802 once they boot up. The portable detector control device and the imaging detectors may boot up at different instances, i.e., not at the same time. The imaging detectors may publish their status information to all the portable detector control devices. Based on the status information, the portable detector control device communicates with an imaging detector associated with the portable detector control device. The portable detector control device stores the database of associated imaging detectors. The portable detector control device compares all the imaging detectors with the associated imaging detectors stored in the database.

(0042] The portable detector control device identifies an imaging detector with which it may communicate at step 804. The imaging detector identified may be associated with the portable detector control device. Thereafter at step 806 a

communication link between the portable detector control device and the identified imaging detector is established. The portable detector control device instructs the imaging detector to perform imaging of a subject. The portable detector control device initiates an examination process in the associated imaging detector based on user input at step 808. The user input may be received through an input device of the portable detector control device. The portable detector control device may also send a unique identifier related to the examination process to be performed to the imaging detector at step 810. The unique identifier may be specific for the examination process. Further the portable detector control device may also communicate an identifier to the imaging detector at step 812. The identifier may be for example a serial number of the portable detector control device that facilitates the imaging detector in identification. [0043J In order to start the examination the portable detector control device needs to select appropriate imaging protocol. Thus the portable detector control device selects an imaging protocol from multiple imaging protocols presented to the portable detector control device at step 814. The imaging protocols may be presented to the user through a display device of the portable detector control device, and the appropriate imaging protocol is selected based on user input. The selected imaging protocol is then communicated to the imaging detector by the portable detector control device at step 816. The selected imaging protocol helps the imaging detector to start the examination process. While conducting the examination process the portable detector control device captures one or more images of the anatomy at step 818. Thereafter at step 820, the captured images may be then communicated to the portable detector control device by the imaging detectors along with the unique identifier associated with the examination process. The captured images are presented as a preview to the user in the portable detector control device at step 822. The portable detector control device comprises a display unit for presenting the captured images. The user reviews these images and it is determined whether the captured images are meeting user's needs based on the

examination process at step 824. If the images are not acceptable then the imaging detector captures images of the anatomy again. Now if the images are acceptable and meets the requirements then portable detector control device instructs the imaging detector to close the examination process and confirm the images at step 826. The images may be confirmed by receiving a user input through the portable detector control device. Then the imaging detector reaches a close exam status and sends back the information of the portable detector control device such as, the unique identifier and the identifier to the portable detector control device.

[0044] The portable detector control device may query for patient information from the user at step 828, Then at step 830 the confirmed images are annotated with the patient information. The patient information may include for example name, age, sex, and health history. For instance the patient information may be tagged with an image. Moreover the confirmed images may be also annotated with other information such as, hospital or medical center information. In an embodiment the patient information and the other information may be appended in a header of the image. This information facilitates in retrieving the images in a convenient manner from the storage system for future use. Further the annotated images may be transferred to one or more of a storage device and printer storage by the portable detector control device at step 832. These annotated images may be retrieved from the storage device when required. Also the annotated images may be preprocessed before sending to the storage device or the printer storage. The preprocessing process may include but not limited to cropping, adding position markers, and other enhancement techniques that may be applied on the annotated images.

[0045] In the medical imaging environment all the imaging detectors may be visible to the multiple portable detector control devices. Thus each portable detector control device may send a connection request to the imaging detectors that are associated. FIG. 9 illustrates a flow diagram of a method 900 of managing a communication link between an imaging detector and a portable detector control device in accordance with an

embodiment. Thus in instance the imaging detector connected to the portable detector control device may receive a new connection request from another portable detector control device at step 902. This connection request may be to initiate the communication between the requester portable detector control device and the imaging detector. The imaging detector then communicates the receipt of the connection request to the connected portable detector control device. The portable detector control device then examines the communication link to check its status. The portable detectors control device allows the requester portable detector control device to override the

communication link based on a status of the communication link at step 904. This communication link is overridden when the status is idle or suspended. In another scenario the portable detectors control device may force close the exam process and thus the communication link is closed thereby allowing overriding of the communication link. Thereafter a communication link is established between the requester portable detector control device and the imaging detector at step 906. However if the communication link between the portable detector control device and the imaging detector is active then the requester portable detector control device is not allowed to override the communication link. Then the requester portable detector control device may need to check if it needs to connect with any other imaging detectors in the medical imaging environment.

[0046] The methods 700, 800 and 900 can be performed using a processor or any other processing device. The method steps can he implemented using coded instructions (e.g., computer readable instructions) stored on a tangible computer readable medium. The tangible computer readable medium may be for example a flash memory, a read-only memory (ROM), a random access memory (RAM), any other computer readable storage medium and any storage media. Although the method of managing the plurality of imaging detectors for imaging of subjects in the medical imaging environment in accordance with another embodiment are explained with reference to the flow chart of F!GS. 7, 8 and 9, other methods of implementing the method can be employed. For example, the order of execution of each method steps may be changed, and/or some of the method steps described may be changed, eliminated, divide or combined. Further the method steps may be sequentially or simultaneously executed for managing the plurality of imaging detectors for imaging of subjects in the medical imaging environment in accordance with another embodiment.
