[0028] One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers’ specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0029] When introducing elements of various embodiments of the present subject matter, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Furthermore, any numerical examples in the following discussion are intended to be nonlimiting, and thus additional numerical values, ranges, and percentages are within the scope of the disclosed embodiments.

[0030] As used herein, the terms “automatic” and “automatically” refer to actions that are performed by a computing device or computing system (e.g., of one or more computing devices) without human intervention. For example, automatically performed functions may be performed by computing devices or systems based solely on data stored on and/or received by the computing devices or systems despite the fact that no human users have prompted the computing devices or systems to perform such functions. As but one nonlimiting example, the computing devices or systems may make decisions and/or initiate other functions based solely on the decisions made by the computing devices or systems, regardless of any other inputs relating to the decisions. [0031] While aspects of the following discussion are provided in the context of handling components (e.g., larger components such as gantry covers or other components (e.g., collimator) of a medical imaging system, the disclosed embodiments can be utilized any components related to other types of object or machines. In addition, although a CT imaging system is provided as an example of a medical imaging system, the disclosed embodiments may be utilized with handling components of MR imaging systems, PET imaging systems, SPECT imaging systems, nuclear NM imaging systems, multi-modality (PET/CT, PET/MR, SPECT/CT) imaging systems, and RT systems.

[0032] Current imaging system gantry cover handling and removal systems have several issues. For example, a typical current gantry cover removal system utilizes a lead screw as an actuation mechanism involving turning the lead screw for up-down movement of the gantry cover, making the up-down movement very cumbersome and timeconsuming. A high pitch lead screw may be faster but needs increased effort to raise the cover. A non-standard high pitch lead screw requiring a customized thread increases the cost and makes use more difficult and complex. In addition, the lead screw is prone corrosion and damage based on environmental conditions and prolonged usage. Thus ,the lead screw requires additional maintenance such as lubrication, cleaning, and prevention of dust. Further, the height to which a dolly can be raised is limited by a lead screw. Thus, in order to achieve higher up-down movement, the length and the pitch has to be increased further. But increasing the pitch reduces the mechanical advantage of the lead screw requiring more effort by the operator for upward lift. If the pitch is not increased, it would lead to a higher time consumption with increasing height to which the dolly can be raised. The typical current gantry cover removal system also requires external tools (either a hand tool or a power tool) for its use, which adds additional cost and causes a dependence on tools making the process less efficient.

[0033] The present disclosure provides embodiments for a component handling system for use during manufacturing or servicing for lifting, removing, supporting, maneuvering and installing large heavy bulky components, equipment, parts, and assemblies. The component handling system reduces the time to maneuver parts or assemblies with ease and reduction of time. In the case of imaging system gantry covers, the time for imaging system gantry cover removal was reduced by 93 percent. The component handling assembly does not require any hand or powered tools for operation, making it easier to use. The component handling assembly does not require maintenance during the product lifecycle as there is no lubrication to be done for moving parts, since there are less parts that are prone to wear and tear. The component handling assembly may not only be used for imaging system gantry cover removal, support, maneuvering, and installation, but the component handling system or assembly may be used for other products as well. The component handling system is configured to accommodate different weights, thus, making it a multiload carrying capacity component handling system (e.g. dolly) by only changing the load of the gas spring. The component handling system is configured to be scalable across all platforms with no or minimal change. The component handling system is also configured to enable components such as a gantry cover to be titled 180 degrees from its normal position to aid in cover maneuverability and ease of serviceability in a limited room layout condition.

[0034] The disclosed embodiments include a component handling system. The component handling system includes at least one component handling assembly. The at least one component handling assembly includes a wheeled base. The at least one component handling assembly also includes a stationary bracket coupled to the wheeled base.

[0038] In certain embodiments, the component handling system includes an imaging system component handling system. In certain embodiments, the component includes a gantry cover. In certain embodiments, the component includes a collimator.

[0039] The disclosed embodiments include a component handling system. The component handling system includes at least two component handling assemblies. Each component handling assembly of the at least two component handling assemblies includes a wheeled base. Each component handling assembly of the at least two component handling assemblies also includes a stationary bracket coupled to the wheeled base. Each component handling assembly of the at least two component handling assemblies further includes a moving bracket coupled to the stationary bracket, wherein the moving bracket is configured to move in a vertical direction relative to the stationary bracket. Each component handling assembly of the at least two component handling assemblies even further includes a gas spring configured to actuate movement of the moving bracket in the vertical direction relative to the stationary bracket. Each component handling assembly of the at least two component handling assemblies further includes a pivoting bracket assembly coupled to the moving bracket. The pivoting bracket assembly is configured to be rotated in a circumferential direction about a fastener coupling the pivoting bracket assembly to the moving bracket.

[0040] In certain embodiments, respective pivoting bracket assemblies of the at least two component handling assemblies are configured to be disposed on and interface with opposite sides of the component. In certain embodiments, the component includes a gantry cover.

[0041] The disclosed embodiments include a component handling assembly. The component handling assembly includes a wheeled base.

The pivoting bracket assembly is configured to rotate the component interfacing with the pivoting bracket assembly to different positions between 0 and 180 degrees.

[0042] The disclosed gantry cover handling assembly includes a gas spring for lifting the gantry covers. The gas spring is used as the up and down actuation mechanism. The disclosed gantry cover handling assembly is a portable imaging system front gantry cover removal system that uses a gas spring for lifting and supporting the gantry covers. The assembly provides upward movement of the gantry covers. The entire cover removal process with the disclosed gantry cover handling system takes less than one minute. [0043] The disclosed component handling assembly is a portable gas spring assisted component handling system for removing, supporting, moving, and installing components, equipment, parts, and assemblies during manufacturing and/or servicing. In an exemplary embodiment, the disclosed component handling assembly is a disclosed portable gas spring assisted gantry cover handling assembly for removing, supporting, moving, and installing imaging system gantry covers during manufacturing and/or servicing.

[0044] In an exemplary embodiment, it usually requires at least two gantry cover handling assemblies for removing, supporting, moving, and installing imaging system gantry covers during manufacturing and/or servicing. One gantry cover handling assembly on each side of a gantry cover. The gas spring is used for load balancing, supporting and moving a gantry cover up and down. The gas spring further provides for guided vertical movement using one of the following: 1) an aluminum rod and guided bracket for smooth up-down movement; or 2) telescopic rails for up-down movement. Two levels of handles are provided to accommodate a field engineer’s height variation. Lifting height is variable and adjustable by changing the length of the stationary bracket or bottom post. An up-down movement guide is provided by using one of the following: 1) a linear profile guide; or 2) a pivot bracket and a linear bracket.

[0045] The gantry cover handling assembly includes a gas spring telescopic design with separate bolts for pivot movement and up-down movement. The design may be scaled up to any height and adjusted accordingly as per user requirement, based on necessity. Also, gantry cover handling assembly can accommodate different weights making it muti-load carrying capacity material handling apparatus by only changing load of the gas spring.

[0046] With the preceding in mind and referring to FIG. 1, a computed tomography (CT) imaging system 10 is shown, by way of example. The CT imaging system 10 includes a gantry 12. The gantry 12 includes a gantry cover 11 configured to be located on a front portion of the gantry housing adjacent the CT table 46. The gantry 12 has an X-ray source 14 that projects a beam of X-rays 16 toward a detector assembly 15 on the opposite side of the gantry 12. The X-ray source 14 projects the beam of X-rays 16 through a pre-patient collimator assembly 13 that determines the size and shape of the beam of X-rays 16. The detector assembly 15 includes a collimator assembly 18 (a post-patient collimator assembly), a plurality of detector modules 20 (e.g., detector elements or sensors), and data acquisition systems (DAS) 32. The plurality of detector modules 20 detect the projected X-rays that pass through a subject or object 22 being imaged, and DAS 32 converts the data into digital signals for subsequent processing. Each detector module 20 in a conventional system produces an analog electrical signal that represents the intensity of an incident X-ray beam and hence the attenuated beam as it passes through the subject or object 22. During a scan to acquire X-ray projection data, gantry 12 and the components mounted thereon rotate about a center of rotation 25 (e.g., isocenter) so as to collect attenuation data from a plurality of view angles relative to the imaged volume.

[0047] Rotation of gantry 12 and the operation of X-ray source 14 are governed by a control system 26 of CT imaging system 10. Control system 26 includes an X-ray controller 28 that provides power and timing signals to an X-ray source 14, a collimator controller 29 that controls a length and a width of an aperture of the pre-patient collimator 13 (and, thus, the size and shape of the beam of X-rays 16), and a gantry motor controller 30 that controls the rotational speed and position of gantry 12. An image reconstructor 34 receives sampled and digitized X-ray data from DAS 32 and performs high-speed image reconstruction. The reconstructed image is applied as an input to a computer 36, which stores the image in a storage device 38. Computer 36 also receives commands and scanning parameters from an operator via console 40. An associated display 42 allows the operator to observe the reconstructed image and other data from computer 36. The operator supplied commands and parameters are used by computer 36 to provide control signals and information to DAS 32, X-ray controller 28, collimator controller 29, and gantry motor controller 30. In addition, computer 36 operates a table motor controller 44, which controls a motorized table 46 to position subject 22 and gantry 12. Particularly, table 46 moves portions of subject 22 through a gantry opening or bore 48. [0048] FIG. 2 is a perspective view of an existing component handling system or assembly 60, such as a gantry cover handling system or assembly. The existing gantry cover handling system includes a lead screw 62 for lifting the gantry covers. The lead screw rotation 64 is used as the up and down actuation mechanism. In particular, a moving bracket 66 (e.g., top post) is moved up and down relative to a to a stationary bracket 68 (e.g., bottom post). The current gantry cover handling system 60 is a portable imaging system front gantry cover removal system that uses the lead screw 62 for lifting and supporting the gantry covers. The system provides upward movement of the gantry covers. The entire cover removal process with the current gantry cover handling system takes about 35 to 40 minutes. The component handling system or assembly 60 utilizing the lead screw 62 is prone to corrosion and damage based on the environmental conditions and prolonged usage. This requires additional maintenance like prevention from dust, lubrication, and cleaning.

[0049] The height to which the gantry cover handling system 60 can be raised is limited by the length of the lead screw 62, so to achieve a higher up-down movement, the length and pitch of the lead screw 62 will need to be increased. Increasing the pitch would reduce the mechanical advantage of the lead screw 62 requiring more effort by the operator for upward lift. If the pitch is not increased, it would lead to higher time consumption with increasing height. These conditions limit the height to which the gantry cover handling system can be raised. A longer lead screw 62 is needed.

[0050] FIG. 3 is a perspective view of a component handling assembly 70 (e.g., dolly) of a component handling system 72. In certain embodiments, the component handling system 72 (and the component handling assembly 70) is configured for use during manufacturing or servicing for lifting, removing, supporting, maneuvering and installing large heavy bulky components, equipment, parts, and assemblies. In certain embodiments, the component handling system 72 is a medical imaging component handling system and the component handling assembly 70 is a medical imaging component handling assembly. In certain embodiments, the component handling system 72 is a medical imaging gantry cover handling system and the component handling assembly 70 is a medical imaging gantry cover handling assembly.

For example, in handling a gantry cover, a respective component handling assembly 70 may be utilized on opposite sides of the gantry cover.

[0051] As depicted, the component handling assembly 70 includes a wheeled base 74 having a base 76 coupled to a plurality of wheels 78 (which enable free lateral movement). The component handling assembly 70 includes a stationary bracket 80 (e.g., bottom post) coupled (e.g., directly) to the wheeled base 74. For example, the stationary bracket 80 may be welded to the wheeled base 74. The component handling assembly 70 further includes a moving bracket 82 coupled to the stationary bracket 80. The moving bracket 82 is configured to move in a vertical direction 84 (e.g., up and down) relative to the stationary bracket 80. The moving bracket 82 is configured to move in the vertical direction 84 relative to the stationary bracket 80 in a telescopic manner (e.g., with the stationary bracket 80 at least partially disposed within the moving bracket 82). The component handling assembly 70 even further includes a gas spring 86 configured to actuate movement of the moving bracket 82 in the vertical direction 84 relative to the stationary bracket 80. As depicted, the gas spring 86 is disposed within the moving bracket 82. A load of the gas spring 86 is configured to be changed to enable the component handling assembly 70 to handle different weights.

The pivoting bracket assembly 88 is configured to interface with a component (e.g., of an imaging system) to be handled by the component handling system 72. The features (e.g., slots, protrusions, etc.) on the pivoting bracket assembly 88 may vary based on the component to be handled by the component handling assembly 70. The pivoting bracket assembly 88 is configured to rotate the component (e.g., gantry cover) interfacing with the pivoting bracket assembly 88 to different positions between 0 and 180 degrees. As depicted, the component handling assembly 70 includes a handle 91 coupled to the moving bracket 82. In particular, a respective handle 91 is disposed on opposite sides of the moving bracket 82. The handle 91 is configured to facilitate the movement of the moving bracket 82 in the vertical direction 84. As depicted, the handle 91 extends in a perpendicular direction relative to a length of the moving bracket 82.

The number of additional fasteners 92 may vary (e.g., 1, 2, 3, or more additional fasteners). As depicted, the moving bracket 82 is coupled to the stationary bracket 80 via the additional fasteners 92 separate from the fastener 90 coupling the pivot bracket assembly 88 to the moving bracket 82 so that the movement of the moving bracket 82 in the vertical direction 84 is separate from rotation of the pivoting bracket assembly 88 in a circumferential direction 94 about the fastener 90. The tightening of the fastener 90 (e.g., via a nut) provides controlled movement in the circumferential direction 94. The additional fasteners 92 extend through a slot 96 (e.g., vertical slot) in the moving bracket 82 to enable movement of the moving bracket 82 relative to the stationary bracket 80.

[0057] FIG. 10 is a schematic diagram illustrating design scalability of the component handling assembly 70 in FIG. 7. This design scalability also applies to the component handling assembly 70 in FIG. 3. A length of the stationary bracket 80 utilized with the component handling assembly 70 may vary as indicated by arrow 116. The component handling assembly 70 (e.g., dolly) on the left of FIG. 10 has a height range of up to 250 millimeters. With alteration of the length of the stationary bracket 80 and a change in a stroke of the gas spring 86, the component handling assembly 70 (e.g., dolly) can be scaled to any height. The component handling assembly 70 (e.g., dolly) on the right of FIG. 10 has a height range of up to 500 millimeters. The load of the gas spring 86 can be changed to enable the component handling assembly 70 to handle different weights. The component handling assembly 70 includes handles 91 as described above.

[0058] FIG. 11 is a schematic diagram illustrating the ability of the pivoting bracket assembly 88 of the component handling assembly 70 to be rotated to different positions.

The component handling assembly 70 includes a pin 120 configured to be inserted within a respective hole 118 of the plurality of holes 118 and a corresponding hole 122 in the moving bracket 82 to hold a respective rotational position of the pivoting bracket assembly 88 (i.e., locking pivot movement) and a position of the component being handled by the component handling assembly.

[0059] FIG. 12 is a schematic diagram of the component handling system 72 tilting the gantry cover 11 (e.g., of a CT system) into different positions. The component handling system 72 includes a pair of component handling assemblies 70 (such as described in FIG. 3) disposed on opposite sides of the gantry cover 11. The respective pivoting bracket assemblies 88 of the pair of component handling assemblies 70 interface with opposite sides of the gantry cover 11. In a first position 124 (e.g., normal position), the gantry cover 11 is at 0 degrees tilt one end of table 46. In a second position 126, the gantry cover 11 is at 90 degrees tilt and can be moved in the second position 126 to the other end of the table 46. In a third position 128, the gantry cover 11 is at 180 degrees tilt with the gantry cover 11 located at the other end of the table 46. The gantry cover 11 (or any other component couple to the pivoting bracket assemblies) may be tilted in 20 degree increments between 0 and 180 degrees.

[0060] FIG. 13 is a schematic diagram illustrating imaging system gantry cover removal in a restricted room layout (without the ability to utilize a 180 degree cover tilt option) (e.g., utilizing the existing component handling system or assembly 60 in FIG. 2). One of the major factors used to determine a minimum room layout for an imaging system is based on the area needed for gantry cover removal. The minimum room size required has a width 130 of 3800 millimeters and a length 132 of 4900 millimeters.

[0061] FIG. 14 is a schematic diagram illustrating imaging system gantry cover removal in a restricted room layout (with the ability to utilize a 180 degree cover tilt option) (e.g., utilizing the component handling system 72 in FIG. 3 or FIG. 7). The minimum room size required now has a width 134 of 3000 millimeters and a length of 136 of 4700 millimeters. Thus, use of the component handling system 72 and the 180 degree cover tilt option results in the width 134 of the room required being reduced by 800 millimeters and the length 136 of the room required being reduced by 200 millimeters. The component handling system 72 with the 180 degree cover tilt option aids gantry cover maneuverability and ease of serviceability in limited room layout conditions.

[0062] FIG. 15 is a schematic diagram of different features to enable multiple height variations for the component handling assembly 70. As depicted on the left side of FIG. 15, the stationary bracket 80 includes toward the bottom a slot 138 that accommodates for variation in the height of the component (e.g., gantry cover) handled by the component handling assembly 70. The component handling assembly 70 also includes a pin 140 configured to be inserted within corresponding holes 142, 144 of both the moving bracket 82 and the stationary bracket 82 when aligned to fix a height of the component handling assembly 70 (and the component such as gantry cover 11 handled by the component handling assembly 70). On the right side of FIG. 15, the component handling system 72 is handling the gantry cover 11 (with a pair of the component handling assemblies 70 flanking the gantry cover 11). On the top right of FIG. 15, the gantry cover 11 is at maximum height (via the component handling system 72). On the bottom right of FIG. 15, the gantry cover 11 is at minimum height (via the component handling system 72). Via the component handling system 72, the vertical movement (up and down movement) of the gantry cover 11 has range of 250 millimeters. Removal of pins 140 from the respective component handling assemblies 70 handling the gantry cover results in the semi-automatic vertical raising of the gantry cover 11 (due to the gas spring).

[0063] FIG. 16 is a schematic diagram of different positions for the handles 91 of the component handling assembly 70. As depicted, component handling assembly 70 may include multiple receptacles 146 vertically spaced apart on opposite sides of the moving bracket 82 for ends of the handles 91 to inserted in. The receptacles 146 provide different positions for placing the handles 91 to accommodate the height of the operator (e.g., field engineer (FE)). As depicted, the receptacles 146 are spaced by a distance 148 of 150 millimeters. The distance 148 may vary. A length 150 of the handles 91 may vary. As depicted, the depicted the length 150 of the handles is 150 millimeters. FIG. 17 depicts the handle 91 inserted within the receptacle 146. The handles 91 are easy to use and have enough length and grip for easy up and down movement. As depicted, the handles 91 are round and have a washer 152 at the end adjacent the receptacle 146

[0064] FIG. 18 is a schematic diagram of the stationary bracket 80 of the component handling assembly 70 having a marking 154 for maximum height.

In certain embodiments, the marking 154 may be a silk screen printing on the stationary bracket 80 as depicted in FIG. 18. In certain embodiments, the marking 154 may be etched on the surface of the stationary bracket 80.

[0065] FIG. 19 is a perspective view of the component handling assembly 70 of the component handling system 72 (e.g., handling a collimator 13). The component handling system 72 is as described in FIG. 3 with the exception of the pivoting bracket assembly 88. As depicted, the pivoting bracketing assembly 88 has features 156 configured specifically for interfacing with the collimator 13 (e.g., for collimator servicing and assembly).
