The details of one or more variations of the subject matter described herein are set forth in the accompanying drawings and the description below. Other features and advantages of the subject matter described herein will be apparent from the description and drawings, and from the claims.
These and other features will be more readily understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
It is noted that the drawings are not necessarily to scale. The drawings are intended to depict only typical aspects of the subject matter disclosed herein, and therefore should not be considered as limiting the scope of the disclosure.
Determining an operation of an X-ray tube can require external components to be coupled to internal components of the X-ray tube, such as a cathode of the X-ray tube, in order to measure diagnostic data indicative of the operation of the X-ray tube. Often X-ray tube applications may not permit or can be difficult to enable such coupling due to size or space constraints within the X-ray tube or the application environment in which the X-ray tube is operating.
In addition, the use of various wires to couple the X-ray tube or components therein to monitoring systems can also be problematic. For example, in high voltage applications, high voltage tension can be generated at the input receptacle of the X-ray tube, which can unload to internal wiring and cause the wiring to short. The wiring used for a grid voltage supply or for a filament voltage supply can experience defects, or shorts, as a result of the high voltage tension. Such defects can cause the X-ray tube, and a monitoring system to which the X-ray tube may be coupled, to operate inaccurately and malfunction.
An improved X-ray tube is described herein. The X-ray tube described herein can provide more reliable operational data of the X-ray tube and can reduce or eliminate the incidence of defects or malfunctions within the X-ray tube due to high voltage tension at the supply side of X-ray tube. The X-ray tube described herein can include a connector configured within an input receptacle of the X-ray tube. The connector an include one or more circuits configured to receive an input signal and to generate an output signal indicative of an operational characteristic of the X-ray tube.
The connector 210 can include electronic circuitry configured to determine operational characteristics of the X-ray tube 105. For example, the connector 210 can include a printed circuit board. One or more circuits can be configured on the connector 210 to receive an input signal and to generate an output signal indicative of an operational characteristic of the X-ray tube. For example, the operational characteristics can include a tube-type identifier, a filament temperature, a filament current, an electron emission current, or at least one parameter associated with a beam shape emitted by the X-ray tube 105.
For example, the connector 210 can include one or more supply voltage transformers 305. The connector 210 can also include at least one communication transceiver 310. The communication transceiver 310 can be configured as a wireless communication transceiver 310 as shown in
In some embodiments, the connector 210 can include a printed circuit board and the electrical components and circuitry described above can be configured on the connector 210 via the printed circuit board.

In operation 620, the data processor 420, 535 can determine, based on the received data, at least one operational characteristic of the X-ray tube 105, 510. For example, the data processor can determine that the operational characteristic is one of a tube-type identifier, a filament temperature, a filament current, an electron emission current, or at least one parameter associated with a beam shape emitted by the X-ray tube. In operation 630, the data processor 420, 535 can provide the at least one operational characteristic. For example, the data processor 420, 535 can provide the operational characteristic via a display 445, 560.
Responsive to providing a tube-type identifier as the operational characteristic, the data processor 420, 535 can further determine a tube setting corresponding to the tube-type identifier in operation 640. In response, in operation 650, the data processor 420, 535 can transmit the tube-setting to a controller 430, 545 coupled to the data processor 420, 535 and to a voltage generator coupled to the input receptacle 110, such as the voltage generator 450, 565 shown in
Exemplary technical effects of the apparatus, systems, and methods described herein include, by way of non-limiting example, determining an operational characteristic of an X-ray tube using a maintenance free connector configured within the input receptacle of the X-ray tube. The operational characteristic can be used by a system in which the X-ray tube is included to control an input signal or input voltage supplied to the input receptacle from a voltage generator. Determining the operational characteristics of the X-ray as described herein can enable operational diagnosis and monitoring of the X-ray tube for a wide variety of applications. For example, determining the operational characteristic of the X-ray tube can be used to monitor filament temperature, filament current, electron emission current, tube-types, and beam shape parameters of the X-ray tube. The X-ray tube system configured to perform the methods described herein can provide more accurate diagnosis of operational faults or malfunctions and thus enable more robust operation of X-ray tubes. The X-ray system described herein can also include improved interfaces for providing an integrity state. Further, the X-ray tube system can cause a change in operation of the X-ray tube based on the determined operational characteristic which can ensure the X-ray tube operates within acceptable or safe operating parameters.

The features illustrated or described in connection with one exemplary embodiment can be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention. Further, in the present disclosure, like-named components of the embodiments generally have similar features, and thus within a particular embodiment each feature of each like-named component is not necessarily fully elaborated upon.

A computer program (also known as a program, software, software application, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file. A program can be stored in a portion of a file that holds other programs or data, in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub-programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network.
The processes and logic flows described in this specification, including the method steps of the subject matter described herein, can be performed by one or more programmable processors executing one or more computer programs to perform functions of the subject matter described herein by operating on input data and generating output.

Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processor of any kind of digital computer. Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks.

The techniques described herein can be implemented using one or more modules. As used herein, the term “module” refers to computing software, firmware, hardware, and/or various combinations thereof. At a minimum, however, modules are not to be interpreted as software that is not implemented on hardware, firmware, or recorded on a non-transitory processor readable recordable storage medium (i.e., modules are not software per se). Indeed “module” is to be interpreted to always include at least some physical, non-transitory hardware such as a part of a processor or computer. Two different modules can share the same physical hardware (e.g., two different modules can use the same processor and network interface). The modules described herein can be combined, integrated, separated, and/or duplicated to support various applications. Also, a function described herein as being performed at a particular module can be performed at one or more other modules and/or by one or more other devices instead of or in addition to the function performed at the particular module. Further, the modules can be implemented across multiple devices and/or other components local or remote to one another. Additionally, the modules can be moved from one device and added to another device, and/or can be included in both devices.
The subject matter described herein can be implemented in a computing system that includes a back-end component (e.g., a data server), a middleware component (e.g., an application server), or a front-end component (e.g., a client computer having a graphical user interface or a web browser through which a user can interact with an implementation of the subject matter described herein), or any combination of such back-end, middleware, and front-end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), e.g., the Internet.
Approximating language, as used herein throughout the specification and claims, can be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “about,” “approximately,” and “substantially,” are not to be limited to the precise value specified. In at least some instances, the approximating language can correspond to the precision of an instrument for measuring the value. Here and throughout the specification and claims, range limitations can be combined and/or interchanged, such ranges are identified and include all the sub-ranges contained therein unless context or language indicates otherwise.
One skilled in the art will appreciate further features and advantages of the invention based on the above-described embodiments. Accordingly, the present application is not to be limited by what has been particularly shown and described, except as indicated by the appended claims.
