Description

BACKGROUND

Field of the Present Disclosure

The present disclosure relates to the field of a cabinet x-ray irradiator incorporating a system and method for incorporating a camera, either high definition or standard resolution, taking an optical image both live and static and displaying the resulting images.

Background

Today, conventional cabinet x-ray irradiators do not have a way to visualize the sample placed into the cabinet once the door is closed.

With a unit incorporating a camera, the technician can utilize the resultant photo or optical image to expeditiously visualize the specimen and verify that it is situated properly within the sample chamber.

Cabinet X-ray Irradiators are considered the optimal replacement for live-source irradiators and with the incorporation of a video link and/or option that can be displayed on the control console monitor it would expedite and verify that the specimen being irradiated is located properly.

DETAILED DESCRIPTION

In general, aspects of this disclosure include a device (cabinet x-ray irradiator system) utilizing a camera to capture an optical image (in black and white, gray scale or color, preferably color), preferably in real-time, of a sample or specimen also being irradiated.

The photo/captured camera optical image, preferably in real-time, may be displayed on the monitor either overlaid onto the program on the monitor of the sample or as back to back viewing on a monitor between two images or a side-by-side or Picture-In-a-Picture (PIP) displayed adjacent to the program. A device capturing an optical image, preferably in real-time, of the specimen facilitates confirmation and orientation for the technician.

A preferred embodiment system would be to incorporate an HD (high-definition) optical camera into a cabinet x-ray irradiator unit allowing the system to capture an HD optical image so obtained can be displayed as disclosed herein.

The present disclosure and embodiments included therein can relate to specimen irradiation but the disclosure is not isolated to specimen irradiation but may be utilized, for irradiation of organic and non-organic samples or specimens, requiring a cabinet x-ray irradiation system but is not limited to just an HD camera but to any camera fitting within the confines of the cabinet x-ray system.

Specimen tomography is a three-dimensional specimen imaging system. It involves acquiring images of a sample at multiple viewpoints, typically over an arc or linear path. The three-dimensional image is constructed by the reconstruction of the multiple image data set.

FIG. 1 schematically illustrates one embodiment of the orientation of the X-ray source 10 as seen when the door 24 is opened and the X-ray source 10 is locate at approximately 0°, reference point 14 in this example, within the X-ray cabinet 22. In this embodiment, the motion of the X-ray source 10 can generally occur from the back to the front of the X-ray cabinet 22 with the specimen tray 20 oriented, or otherwise disposed, at the base 26 of the X-ray cabinet 22,

FIG. 3 illustrates one embodiment of an exemplary workflow from initiating 302 the system 100 through irradiation, and display 324 of data images collected of the sample 18.

As will be generally understood, the system 100 is initiated 302, the X-ray cabinet door 24 opened 304, and the sample 18 placed into 306 the X-ray cabinet chamber 28. As shown in FIG. 1, for example, the sample 18 is positioned on the sample tray 20 in a suitable manner. The door 24 is closed 308.

The data and information regarding the sample 18, including any other suitable information or settings relevant to the irradiation process and procedure, is entered 310 into the computer 470. The irradiation is initiated 312. The system 100 will capture 316 images.

The captured images are stored 318 and then displayed 324 in real-time

FIG. 3 shows one embodiment of an X-ray Cabinet System 400 incorporating aspects of the present disclosure. In this embodiment, the X-ray Cabinet System 400 is mounted on wheels 458 to allow easy portability. In alternate embodiments, the X-ray Cabinet System 400 can be mounted on any suitable base or transport mechanism. The cabinet 422 in this example, similar to the exemplary X-ray cabinet 22 of FIG. 1, is constructed of a suitable material such as steel. In one embodiment, the cabinet 422 comprises painted steel defining a walled enclosure with an opening or cabinet chamber 428. Within the cabinet chamber 428, behind door 424, resides an interior space forming a sample chamber 444, which in this example is constructed of stainless steel. Access to the sample chamber 444 is via an opening 446. In one embodiment, the opening 446 of the sample chamber 444 has a suitable door or cover, such as a moveable cover 448. In one embodiment, the moveable cover 448 comprises a door which has a window of leaded glass.

Between the outer wall 421 of cabinet 422 and the sample chamber 444 are sheets of lead 452 that serve as shielding to reduce radiation leakage emitted from the X-ray source 10. In the example of FIG. 4, the X-ray source 10 is located in the upper part 456 of the cabinet 422, in the source enclosure 468. The sample tray 20 is housed in the detector enclosure 460 at an approximate midpoint 462 of the cabinet 422.

The computer 470 receives commands and other input information entered by the operator via a user interface 476, such as a keyboard and mouse for example. In one embodiment, the computer 470 can comprise a touch screen or near touch screen device. Although the aspects of the disclosed embodiments will generally be described with respect to a computer 470, it will be understood that the computer 470 can comprise any suitable controller or computing device. Such computing devices can include, but are not limited to, laptop computers, mini computers, tablets and pad devices.

The computer 470 can be configured to communicate with the components of the X-ray cabinet system 400 in any suitable manner, including hardwired and wireless communication. In one embodiment, the computer 470 can be configured to communicate over a network, such as a Local Area Network or the Internet.

Referring to FIG. 4, there is shown the interconnection of an embodiment of a camera 30 incorporated into a Cabinet X-Ray Unit which connects to and can be controlled by the computer 470 via cable 800 including, for example a USB cable. Other wireless formats for communication between camera 30 and computer 470 can also be used in embodiment of the present disclosure. Camera 30 may include an optical lens assembly 32 through which an optical image passes and is focused upon an electronic light-sensitive sensory array included in the camera body 34. The optical image can then be sent using an electronic signal from the sensory array to the computer 470 via cable 800 or other wireless formats. The optical image can also be stored in the computer 470 for future examination and viewing, including storage in memory (e.g., RAM) or a disc recording medium (e.g., CD, DVD, etc.)

Camera 30 is included in FIG. 1 as well showing embodiments in camera 30, for example, located at position 15 in the cabinet x-ray unit such that it is capable of capturing a visual image of sample 18 in cabinet 22 and x-ray cabinet chamber 28 in FIG. 1 and in cabinet 422

In the systems and methods included in this disclosure as well as the embodiments disclosed herein, the resulting optical camera images can be displayed each alone or together as overlaid together, adjacent or PIP (Picture-in-Picture) on the monitor FIGS. 4-472. This, in turn, provides more flexibility for a clinician or other user of the system and simplifies the procedure. The separate images from the camera can be stored in the computer hard drive on the system 470 or a separate memory device, such as for example, a separate hard drive, flash drive, CD-ROM, DVD, etc. for future analysis. The camera can capture a visible light or other electromagnetic wavelength reflected or emitted by the sample or portions thereof, for example, though the use of fluorescent or other markers using a suitable light source where required. Manual input for operation of the cabinet x-ray unit may be initiated via keyboard or monitor touch screen and the resulting image from both the manual-initiated examination can be displayed on the screen and configured in accordance with one example embodiment of the present disclosure.

Indeed, it is appreciated that the system and its individual components can include additional features and components, though not disclosed herein, while still preserving the principles of the present disclosure. Note also that the base computer can be one of any number devices, including a desktop or laptop computer, etc.
