Description

Device for upgrading simulation X-ray machine

Technical Field

The invention relates to a device used in upgrading, in particular to a device for upgrading an analog X-ray machine.

Background

Digital X-ray machines are becoming more and more widely used because of their inherent advantages over analogue X-ray machines. For a large number of analog X-ray machines still in use at present, a method of adding an upgrading device can be generally adopted to upgrade the analog X-ray machines into digital X-ray machines.

The existing upgrading device can enable an upgraded X-ray machine to have a function of wirelessly transmitting data, namely: and transmitting the data generated by the X-ray detector to a server in a wireless mode. Such an X-ray detector can be easily moved and used between different X-ray machines. Data transmission between the X-ray detector and the server is typically accomplished through a wireless Access Point (AP) as a bridge.

For the wireless between the X-ray detector and the AP, one existing device for upgrading the simulation X-ray machine fixedly connects one X-ray detector to one AP after upgrading is completed, and the other existing device for upgrading the simulation X-ray machine adopts a means similar to wireless roaming, and allows one X-ray detector to be connected to any AP after upgrading is completed. If an X-ray detector is fixedly connected to an AP, the detector cannot be shared among multiple sets of X-ray machines, and if the X-ray detector is allowed to be connected to any AP, the quality of a wireless link may be unreliable due to switching of wireless connections.

Therefore, it is desirable to provide a device for upgrading an analog X-ray machine, which ensures reliable quality of the radio link and which enables the upgrading device to be shared among multiple sets of X-ray machines.

It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

According to the upgrading device provided by the embodiment of the invention, generation and setting of the Service Set Identifier (SSID) transmitted by the wireless AP and the Service Set Identifier (SSID) of the X-ray detector corresponding to the SSID are improved, so that after the analog X-ray machine is upgraded to the digital X-ray machine by using an upgrading Kit (Updide Kit), the X-ray detector can be shared among a plurality of sets of X-ray machines, and the quality of a wireless link is reliable.

In one embodiment of the invention, the device can be used for upgrading a stationary X-ray machine. Referring to fig. 1, fig. 1 is a schematic diagram of one embodiment of the apparatus of the present invention for upgrading a stationary analog X-ray machine.

In the embodiment shown in fig. 1, the means for upgrading the analog X-ray machine 100 may comprise: at least one X-ray detector 101, a hard wireless Access Point (AP)102, and an imaging server 103. The X-ray detector 101 is operable to receive X-rays transmitted through the subject emitted by the stationary analog X-ray machine 100 and convert them into digitized electrical signals. The X-ray detector 101 may be integrated with a wireless network card, and at least one of the Service Set Identifiers (SSID) configured in the wireless network card is fixed. In an embodiment of the present invention, only one Service Set Identifier (SSID) may be configured in the wireless network card, that is: the wireless network card can only connect to one wireless Access Point (AP) that transmits the SSID. The hard AP102 may be configured to receive data from the wireless network card, and the hard AP102 may communicate with the imaging server 103 in a wired manner. The hard AP102 may be located within an exposure chamber (within the dashed box in FIG. 1) in which the stationary simulated X-ray machine 100 is located.

When the device of the invention is used in the application scenario shown in fig. 1, namely: for upgrading a stationary X-ray machine, the imaging server 103 may be inserted onto the base 104 such that it is always electrically connected to the base 104, thereby providing power to it via the base 104. In one embodiment of the present invention, when the imaging server 103 is electrically connected to the base 104, the imaging server 103 may turn on the circuit that powers the hard AP102, i.e.: the hard AP may be powered and operated by the cradle 104 under control of the imaging server 103. Data communication lines from the hard AP102 may also be connected to the base 104 to enable communication between the hard AP104 and the imaging server 103.

In one embodiment of the invention, the hard AP may transmit only one SSID when the imaging server 103 is electrically connected to the base 104. Thus, at a certain point in time, only one wireless network card on the probe 101 can access the hard AP 102. When another X-ray detector needs to be connected to the hard AP102, a service set identification change command may be issued to the hard AP102 to change the SSID transmitted by the hard AP102 to the SSID configured in the X-ray detector that needs to be newly accessed. In an embodiment of the present invention, the SSID transmitted by the hard AP102 and the SSID configured in the wireless network card of the X-ray detector 101 may be generated based on or equal to the MAC address of the wireless network card. In an embodiment of the present invention, the wireless access password (e.g., the access password in WPA 2) corresponding to the SSID may be generated based on the MAC address of the wireless network card and by using a preset password generation algorithm. Thus, a newly accessed X-ray detector is required to successfully access the hard AP102 and the X-ray detector originally connected to the hard AP102 is disconnected. This makes it possible to share the X-ray detector 101 of the present invention between different stationary analog X-ray machines and to ensure the reliability of the wireless connection.

In one embodiment of the invention, the service set identification change command may be issued by a user or configuration engineer through a console that simulates the wired connection already available to the X-ray machine. In another embodiment of the present invention, the service set identification change command may also be issued by the mobile console 105 in the apparatus of the present invention. In one embodiment of the present invention, the mobile console 105 may be a tablet computer, a laptop computer, or the like.

In one embodiment of the present invention, mobile console 105 may be wirelessly connected to imaging server 103, such that a soft AP may be integrated within imaging server 103, which may transmit only one SSID for communication with mobile console 105, and accordingly, may configure mobile console 105 with only one SSID that is the same as the SSID transmitted by the soft AP. In this way, it is ensured that a mobile console 105 is reliably connected to an imaging server 103. In one embodiment of the present invention, both the SSID transmitted by the soft AP and the SSID configured in the mobile console 105 can be generated based on the device identifier (Serial Number) of the imaging server 103 or be equal to the device identifier of the imaging server 103. In one embodiment of the present invention, the wireless access code corresponding to the SSID (e.g., the access code of WPA2 standard) may be generated based on the hardware address of mobile console 105 and using a predetermined code generation algorithm.

In one embodiment of the invention, when the imaging server 103 is electrically connected to the base station 104, the softap in the imaging server may transmit only one SSID (when using the mobile console 105) or may not transmit any SSID (when using a wired console).

In one embodiment of the present invention, in order to ensure reliable data transmission between the X-ray detector 101 and the hard AP102, the user may select the wireless transmission channel through the console according to the quality of each wireless channel at the current time. In addition, before starting an exposure, the imaging server 103 may detect the Received Signal Strength (RSSI) of the hard AP102 and the data transmission bandwidth from the X-ray detector 101 to the imaging server 103, and when one of the RSSI and the data transmission bandwidth is smaller than a preset threshold value, an exposure prohibition command may be issued to the analog X-ray machine.

In one embodiment of the invention, the device can also be used for upgrading a mobile X-ray machine. Referring to fig. 2, fig. 2 is a schematic diagram of an embodiment of the apparatus of the present invention for use with a mobile analog X-ray machine.

In the embodiment shown in fig. 2, the means for upgrading the analog X-ray machine 100 may comprise: at least one X-ray detector 101, a soft wireless Access Point (AP), and an imaging server 103. The X-ray detector 101 can be used to receive X-rays emitted by the mobile analog X-ray machine 200 that pass through the subject and convert them into digitized electrical signals. The X-ray detector 101 may be integrated with a wireless network card, and at least one of the Service Set Identifiers (SSID) configured in the wireless network card is fixed. In one embodiment of the present invention, the wireless network card may be configured with only one Service Set Identifier (SSID), that is: can only connect to one wireless Access Point (AP) that transmits the SSID. The soft AP may be configured to receive data from the wireless network card and may communicate with the imaging server 103. In one embodiment of the present invention, the apparatus may further comprise a mobile console 105 connected to the imaging server 103 through a soft wireless access point for convenient manipulation in mobile applications. In one embodiment of the present invention, the mobile console 105 may be a tablet computer, a laptop computer, or the like.

When the device of the invention is used in the application scenario shown in fig. 2, namely: when the mobile X-ray machine is upgraded, the imaging server 103 can be pulled out of the base 104, so that the imaging server is disconnected from the base 104 and works by the power supply of an internal battery. Alternatively, the base 104 may not be required when the device of the present invention is used in the application scenario illustrated in FIG. 2.

In one embodiment of the invention, the softap may be controlled to transmit at least two SSIDs when the imaging server 103 is disconnected from the base station 104. An SSID may be generated based on the device identifier (Serial Number) of the imaging server 103 for establishing a wireless connection between the soft AP and the mobile console 105. The wireless access password (e.g., the access password of WPA 2) corresponding to the SSID may be generated based on the hardware address of the mobile console 105 and by using a preset password generation algorithm.

Another SSID may be generated based on a hardware address of a wireless network card in the X-ray detector 101, and is used to establish a wireless connection between the soft AP and the wireless network card, and a wireless access password (e.g., an access password in the WPA2 format) corresponding to the SSID may be generated based on the MAC address of the wireless network card and by using a preset password generation algorithm. Thus, at a certain point in time, only one wireless network card on the probe 101 can access the soft AP. When another X-ray detector needs to be connected to the soft AP, a service set identification change command can be sent to the soft AP, and the SSID transmitted by the soft AP is changed into the SSID configured in the X-ray detector needing to be newly accessed. Thus, a newly accessed X-ray detector is required to be successfully accessed to the soft AP and the X-ray detector originally connected to the soft AP is disconnected. This makes it possible to share the X-ray detector 101 of the present invention between different mobile analog X-ray machines and to ensure the reliability of the wireless connection.

In one embodiment of the invention, the service set identification change command may be issued by a user or an engineer in charge of the device through a console that simulates an existing wired connection of the X-ray machine. In another embodiment of the present invention, the service set identification change command may also be issued by the mobile console 105 in the apparatus of the present invention.

In an embodiment of the present invention, when the apparatus of the present invention is used to upgrade a mobile X-ray machine, the imaging server 103 may further comprise a wireless network card, which may be used to establish a connection between the imaging server 103 and a hospital network.

In one embodiment of the invention, the device can also be shared between a stationary X-ray machine and a mobile X-ray machine. Referring to fig. 3, fig. 3 is a schematic diagram of a further embodiment of the apparatus for upgrading an analog X-ray machine of the present invention.

As shown in fig. 3, when the apparatus of the present invention is required to be used in the fixed X-ray machine 100, the imaging server 103 may be instructed to enter the fixed operating state, and after the imaging server 103 receives the instruction to enter the fixed operating state, the circuit for supplying power to the hard AP102 may be turned on to operate normally. When mobile console 105 is employed, imaging server 103 may control its internal soft AP to transmit only one SSID for connecting to mobile console 105. When only a wired console is used without using the mobile console 105, the imaging server 103 may control its internal soft AP to be inactive.

When the device of the present invention is required to be used on the mobile X-ray machine 200, the imaging server 103 can be instructed to enter the mobile working state, and after the imaging server 103 receives an instruction to enter the mobile working state, the circuit for supplying power to the hard AP102 can be cut off. When the apparatus of the present invention includes the mobile console 105, the imaging server 103 may further control the soft AP therein to transmit at least two SSIDs, one for connecting to the mobile console 105 and the other for connecting to the X-ray detector 101. The imaging server 103 may also open its internal wireless network card to connect to the hospital network.

In one embodiment of the present invention, the imaging server 103 may be instructed to enter a fixed operating state or a mobile operating state based on the state of the data path between the imaging server 103 and the hard AP 102. Specifically, when it is detected that the state of the data path between the imaging server 103 and the hard AP102 is normal, the imaging server 103 may be instructed to enter the stationary operation state, and when it is detected that the data path between the imaging server 103 and the hard AP102 is disconnected, the imaging server 103 may be instructed to enter the mobile operation state.

In one embodiment of the present invention, the data line from the hard AP102 may be connected to the cradle 104, and thus, when the imaging server 103 is pulled out of the cradle 104 and disconnected from the cradle 104, the data path between the imaging server 103 and the hard AP102 is disconnected, which may trigger the imaging server 103 to enter a mobile operating state. Also, when the imaging server 103 is inserted into the cradle 104, if the data path between the imaging server 103 and the hard AP102 is normally turned on, the imaging server 103 may be triggered to enter a fixed operating state.

The device of the invention can ensure the reliable quality of the wireless link, avoid the X-ray detector from being connected to an unexpected wireless AP, and enable the upgrading device to be shared among a plurality of sets of X-ray machines.

The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention.
