[Technical Field]

[0001] SUMMARY OF THE INVENTION Embodiments of the subject matter disclosed herein relate to methods and systems for supporting an imaging subject. [Background technology]

[0002] Imaging systems (such as computed tomography (CT) imaging systems) are typically used to obtain three-dimensional images of an imaging target. From such imaging, the size and mass of the imaging target can be estimated. The imaging target can be a patient's body and / or a phantom used to characterize and calibrate the imaging system. The position of the imaging target relative to the imaging system's radiation source affects the radiation exposure of the imaging target and the quality of the images produced. Support systems for imaging targets are used in a variety of environments and can be used to position the imaging target in a preferred position relative to the imaging system's radiation source and other elements. For example, support systems for imaging targets are used in medical institutions, where the support system can support the imaging target so that it protrudes from one end of the imaging system's cradle. Summary of the Invention

[0003] In one embodiment, a support system includes a cradle clamp holder for use in an imaging system, the cradle clamp holder including a platform, at least one leveling member, each leveling member including at least one rod, a coupling clamp coupled to the platform at a first end of the platform, the coupling clamp being adjustable between a first position and a second position, and an attachment plate configured to support an imaging subject, the attachment plate coupled directly or indirectly to the platform at a second end opposite the first end of the platform.

[0006] The following description relates to embodiments of an imaging subject support system. In one example, the imaging subject support system is a cradle clamp holder of an imaging system (such as a CT imaging system) illustrated in FIGS. 1-2. An example of a cradle clamp holder is shown in FIGS. 3-5. Additional examples of cradle clamp holders are shown in FIGS. 6-8, with mounting attachments coupled to the cradle clamp holder. The cradle clamp holder can be connected and coupled to a cradle of an imaging system (such as the CT imaging system of FIGS. 1-2), as shown in FIGS. 9-12. FIG. 12 further illustrates using the cradle clamp holder to position an imaging subject (such as a phantom). FIG. 13 illustrates how the cradle clamp holder can be positioned and coupled to the cradle of the imaging system. While FIGS. 3-12 are drawn to scale, other relative dimensions may be used as desired.

[0007] Cradle clamp holders can assist in positioning imaging targets, such as phantoms, table extenders, and / or patient bodies (e.g., arms, hands, heads, other limbs, or the entire body) during computed tomography (CT) examinations and / or calibrations. Some conventional methods for calibrating CT systems using phantoms include placing the phantom directly on a cradle (e.g., on the table of a CT system). The size and / or shape of some phantoms may prevent them from being placed directly on the cradle for scanning. Instead of placing the phantom on a cradle, the phantom may be placed in the scanner using a holder that uses a head holder slot provided on the cradle. The introduction of newer CT systems has made it possible to use larger phantoms for CT system calibration. Depending on the size, shape, and weight of the larger phantom, it may not be possible to use a conventional holder. For example, a large phantom may be too heavy to support a holder that uses a head holder slot so that the large phantom protrudes beyond the edge of the cradle. Current methods for addressing the problem of large phantoms include placing a counterweighted long holder at the top of the cradle to support the large phantom so that it protrudes. However, counterweighted long holders have proven to be large, heavy, and difficult to transport. Furthermore, counterweighted long holders do not provide a mechanism for easily leveling them.

[0008] Rather than using a counterweighted design, a cradle clamp holder is described herein that can support large phantoms and / or other imaging subjects and is further configured to be self-positioning and include features for easier leveling of the cradle clamp holder compared to conventional holders. The cradle clamp holder described herein uses clamps to hold the sides and bottom of a cradle, significantly reducing the overall size and weight of a support system (such as the cradle clamp holder) used to position a phantom and / or patient body. Reducing the size and weight of the support system makes it easier for a user to handle the holder (e.g., position the holder in the cradle) and simplifies packaging and on-site storage of the cradle clamp holder. The cradle clamp holder can provide relatively greater stability to the imaging subject (e.g., reducing vertical and / or horizontal movement of the imaging subject) and can also increase the weight of the imaging subject that can be supported by the support system. Because the weight of the imaging subject can cause the cradle to flex, the cradle clamp holder is provided with multiple adjustment points that allow for adjustment of the leveling of the cradle clamp holder to simplify imaging and / or calibration procedures when the subject is heavy. For example, the cradle clamp holder can be configured to support at least 100 pounds. The cradle clamp holder is configured to support heavy imaging subjects without the use of counterweights, reducing overhang deformation compared to conventional support systems.

[0009] The clamp is used to position and center the cradle clamp holder. When the clamp is tightened (e.g., adjusted from a first position to a second position), the clamp contacts the edge of the cradle, centering the cradle clamp holder relative to the cradle. The cradle clamp holder further includes at least one leveling member, each including at least one rod. The first leveling member, the second leveling member, and the swivel joint are examples of configurations of leveling members used to level the cradle clamp holder relative to the cradle. By adjusting the first leveling member and / or the second leveling member, the vertical position of the cradle clamp holder's platform relative to the cradle can be adjusted. Furthermore, the swivel joint allows the platform to rotate about the central axis of the cradle clamp holder, thereby assisting in platform leveling. In some embodiments, the cradle clamp holder includes a level sensor located on the top surface of and / or embedded in the platform, which provides a visual indicator of whether the cradle clamp holder is level. The cradle clamp holder can also include a verification line on the platform, which is another visual aid for aligning the cradle clamp holder relative to the cradle. For example, the imaging system may output a laser or other alignment line on the cradle. Positioning and leveling the cradle clamp holder can include aligning the verification line with the alignment line output by the imaging system. The cradle clamp holder can also be used to support multiple phantom threats. In some embodiments, the cradle clamp holder can be used to support and / or position a child / infant in a CT system. The cradle clamp holders described herein can be used to increase the efficiency of setup and scan times for CT imaging systems.

[0010] FIG. 1 illustrates an exemplary imaging system 100 configured for CT imaging. In particular, imaging system 100 is configured to image an object, such as a patient, an inanimate object, one or more manufactured parts, and / or a foreign object present in a body (e.g., a dental implant, a stent, and / or a contrast agent). In one embodiment, imaging system 100 includes a gantry 102, which may further include at least one X-ray source 104 capable of emitting an X-ray radiation beam 106 (see FIG. 2 ) for use in imaging an object residing on a table 114 and / or supported to extend beyond the edge of table 114. Specifically, X-ray source 104 is configured to emit X-ray radiation beam 106 toward a detector array 108 located on the opposite side of gantry 102. While FIG. 1 illustrates a single X-ray source 104, in certain embodiments, multiple X-ray sources and multiple detectors may be used to emit multiple X-ray radiation beams and acquire projection data at different energy levels corresponding to the patient. In some embodiments, the X-ray source 104 can achieve dual-energy gemstone spectral imaging (GSI) through rapid kilovolt peak voltage (kVp) switching. In some embodiments, the X-ray detector used is a photon-counting detector capable of distinguishing between X-ray photons of different energies. In other embodiments, two sets of X-ray sources and detectors are used, one set at low kVp and the other at high kVp, to generate dual-energy projections. Thus, it should be understood that the methods described herein can be implemented with single-energy and dual-energy collection techniques.

[0011] In certain embodiments, the CT system 100 further includes an image processor unit 110 configured to reconstruct an image of the target volume of the imaged subject using an iterative image reconstruction method or an analytical image reconstruction method. For example, the image processor unit 110 may reconstruct an image of the target volume of the patient using an analytical image reconstruction method (such as filtered back projection (FBP)). In another example, the image processor unit 110 may reconstruct an image of the target volume of the imaged subject using an iterative image reconstruction method (such as advanced statistical iterative reconstruction (ASIR), conjugate gradient (CG), maximum likelihood expectation maximization (MLEM), model-based iterative reconstruction (MBIR), etc.). As described further herein, in some examples, the image processor unit 110 may use an analytical image reconstruction method (such as FBP) in addition to an iterative image reconstruction method.

[0012] In some CT imaging system configurations, an x-ray source emits a cone-shaped beam of x-ray radiation that is collimated to lie within an XYZ plane in a Cartesian coordinate system, commonly referred to as the "imaging plane." The x-ray radiation beam passes through the object being imaged (such as a patient or subject). After being attenuated by the object, the x-ray radiation beam impinges on an array of detector elements. The intensity of the attenuated x-ray radiation beam received by the detector array depends on the amount of attenuation of the radiation beam by the object. Each detector element in the array produces a separate electrical signal that is a measurement of the attenuation of the x-ray beam at the detector location. The attenuation measurements from all detector elements are acquired separately to produce a transmission profile.

[0013] In some CT systems, the X-ray source and detector array, along with the gantry, rotate around the object to be imaged within the imaging plane, constantly changing the angle at which the radiation beam intersects the object. A group of X-ray attenuation measurements, e.g., projection data, obtained from the detector array for one gantry angle is called a “view.” A “scan” of an object involves obtaining a set of views at different gantry angles, or view angles, during one rotation of the X-ray source and detector. It is contemplated that the benefits of the methods described herein may also be obtained with medical imaging modalities other than CT, and therefore, the term “view” herein is not limited to its use above for projection data from a gantry angle. The term “view” is used to refer to a single data acquisition whenever there are multiple data acquisitions from different angles, whether from CT, positron emission tomography (PET), or single-photon emission CT (SPECT), and / or other modalities, including modalities yet to be developed, as well as combinations thereof in fused embodiments.

[0014] The projection data is processed to reconstruct an image corresponding to a two-dimensional slice taken through the object. Alternatively, in some cases where the projection data includes multiple views or scans, the projection data is processed to reconstruct a three-dimensional rendering of the object. One method for reconstructing an image from a projection data set is referred to in the art as filtered backprojection. Reconstruction techniques for transmission and emission tomography include statistical iterative methods such as maximum likelihood expectation maximization (MLEM) and ordered-subsets expectation-reconstruction techniques, as well as iterative reconstruction techniques. In this process, attenuation measurements from the scan are converted to integers called "CT numbers" or "Hounsfield units," which are used to control the brightness of corresponding pixels on a display device.

[0015] To reduce the total scan time, a "helical" scan can be performed by moving the patient while data for a predetermined number of slices is acquired. In such a system, a single helix is ​​generated from a cone-beam helical scan. The helix described by the cone beam provides projection data from which images for each of the predetermined slices can be reconstructed.

[0016] As used herein, the phrase "reconstructing an image" is not intended to exclude embodiments of the invention in which data representing an image is generated, but a viewable image is not generated. Thus, as used herein, the term "image" refers broadly to both a viewable image and data representing a viewable image. However, in many embodiments, at least one viewable image is generated (or configured to be generated).

[0017] The table 114 includes a cradle 120 supported by a base 122. In some embodiments, the base 122 may include wheels that allow the table 114 to move into and out of a bore 124 of the gantry 102. The cradle 120 includes a support system 116 configured to support an imaging subject (e.g., a phantom and / or a patient body). The support system 116 is coupled to a first end 118 of the cradle 120, allowing the support system 116 and the imaging subject supported by the support system to be inserted into the gantry 102 of the imaging system 100. Conventional examples of the support system 116 may be coupled to the cradle 120 by inserting the support system 116 into a slot in the first end 118 of the cradle 120. However, this coupling method may be insufficient to support large phantoms and / or patient body parts weighing, for example, more than 20-30 pounds. If the conventional support system 116 is used to support an imaging subject so that the imaging subject protrudes beyond the first end 118 of the cradle 120 and into the gantry 102, the conventional support system 116 may become distorted. This may result in the imaging subject being positioned in an undesirable position. For example, the support system 116 (and therefore the imaging subject) may not be level.

[0018] Described herein is an exemplary support system 116, which is a cradle clamp holder configured to couple to the cradle 120 of the imaging system 100 using clamps that contact the sides of the cradle 120. The cradle clamp holder also includes an adjustable leveling element that is used to adjust the level of the cradle clamp holder. The cradle clamp holder can be lighter and more compact than prior art support systems 116. The cradle clamp holder is configured to support (e.g., protrude from the first end 118 of the cradle 120) an imaging subject that is heavier than the imaging subject supported by the prior art support system 116. Further details of the cradle clamp holder are described with reference to FIGS. 3-13.

[0019] FIG. 2 illustrates an exemplary imaging system 200 similar to the imaging system 100 of FIG. 1. According to one aspect of the present disclosure, the imaging system 200 is configured to image an imaging object 204. In one embodiment, the imaging system 200 includes a detector array 108 (see FIG. 1). The detector array 108 further includes a plurality of detector elements 202 that sense an x-ray radiation beam 106 (see FIG. 2) passing through the imaging object 204 (e.g., a patient) to acquire corresponding projection data. Accordingly, in one embodiment, the detector array 108 is fabricated in a multi-slice configuration including multiple rows of cells or detector elements 202. In such a configuration, one or more additional rows of detector elements 202 are arranged in a parallel configuration to acquire projection data.

[0020] In certain embodiments, the imaging system 200 may be moved to different angular positions around the imaged object 204 to acquire desired projection data. Thus, the gantry 102 and the components mounted thereon may be configured to rotate about a center of rotation 206 to acquire projection data at different energy levels, for example. Alternatively, in embodiments where the projection angle relative to the imaged object 204 varies over time, the mounted components may be configured to move along a general curve rather than along a portion of a circle.

[0021] As the x-ray source 104 and detector array 108 rotate, the detector array 108 collects data of the attenuated x-ray beam. The data collected by the detector array 108 is pre-processed and calibrated to condition the data to represent the line integrals of the attenuation coefficients of the scanned imaged object 204. The processed data is commonly referred to as a projection.

[0022] In some embodiments, the individual detectors or detector elements 202 of the detector array 108 may include photon-counting detectors that record the interactions of individual photons in one or more energy bins. It should be understood that the methods described herein may also be implemented with energy-integrating detectors.

[0023] The acquired set of projection data can be used in reference material decomposition (BMD). During BMD, the measured projections are converted into a set of material density projections. The material density projections can be reconstructed to form a pair or set of material density maps (such as maps of bone, soft tissue, and / or contrast agent) or material density images of each reference material. The density maps or density images can be combined in turn to form a volume rendering of the reference materials (e.g., bone, soft tissue, and / or contrast agent) of the imaged volume.

[0024] Once reconstructed, the reference material images produced by the imaging system 200 reveal internal features of the imaged subject 204, represented by the densities of the two reference materials. Density images may be displayed to illustrate these features. In traditional methods of diagnosing medical conditions (such as disease states), and more generally medical events, a radiologist or physician examines hard copies or displays of density images to identify features of interest. Such features include lesions, the size and shape of particular anatomical structures or organs, and other features identifiable within the images based on the skill and knowledge of the individual medical professional.

[0025] In one embodiment, imaging system 200 includes a control mechanism 208 that controls the movement of components, such as the rotation of gantry 102 and the operation of x-ray source 104. In certain embodiments, control mechanism 208 further includes an x-ray controller 210 configured to provide power and timing signals to x-ray source 104. Control mechanism 208 further includes a gantry motor controller 212 configured to control the rotational speed and / or position of gantry 102 based on imaging requirements.

[0026] In certain embodiments, the control mechanism 208 further includes a data acquisition system (DAS) 214 that samples analog data received from the detector elements 202 and converts the analog data into a digital signal for subsequent processing. The DAS 214 may be further configured to selectively collect analog data from a subset of the detector elements 202 into a so-called macro-detector, as described further herein. The data sampled and digitized by the DAS 214 is transmitted to a computer or computing device 216. In one example, the computing device 216 stores the data in a storage device or mass storage 218. The storage device 218 may include, for example, a hard disk drive, a floppy disk drive, a compact disk read / write (CD-R / W) drive, a digital versatile disk (DVD) drive, a flash drive, and / or a solid-state storage drive.

[0027] Additionally, the computing device 216 provides commands and parameters to one or more of the DAS 214, the X-ray controller 210, and the gantry motor controller 212 to control system operation (e.g., data acquisition and / or data processing). In certain embodiments, the computing device 216 controls system operation based on operator input. The computing device 216 receives operator input, including, for example, commands and / or scan parameters, through an operator console 220 operably coupled to the computing device 216. The operator console 220 may include a keyboard (not shown) or a touch screen to enable an operator to specify commands and / or scan parameters.

[0028] 2, multiple operator consoles may be coupled to imaging system 200, for example, to input or output system parameters, request examinations, plot data, and / or display images. Additionally, in certain embodiments, imaging system 200 may be coupled to multiple displays, printers, workstations, and / or similar devices, located locally, remotely, or at entirely different locations, e.g., within a facility or hospital, through one or more configurable wired and / or wireless networks (e.g., the Internet and / or virtual private networks, wireless telephone networks, wireless local area networks, wired local area networks, wireless wide area networks, wired wide area networks, etc.).

[0029] In one embodiment, for example, imaging system 200 includes or is coupled to a picture archiving and communication system (PACS) 224. In an exemplary implementation, PACS 224 is further coupled to remote systems (such as a radiology information system, a hospital information system, and / or an internal or external network (not shown)) to enable operators at different locations to provide commands and parameters and / or access image data.

[0030] The computing device 216 uses operator-supplied and / or system-defined commands and parameters to operate a table motor controller 226, which in turn controls the table 114. The table 114 may be a motorized table. In particular, the table motor controller 226 may move the table 114 so that the imaging subject 204 is properly positioned within the gantry 102 to acquire projection data corresponding to a target volume of the imaging subject 204.

[0031] As described above, DAS 214 samples and digitizes the projection data acquired by detector elements 202. Image reconstructor 230 then performs high-speed reconstruction using the sampled and digitized x-ray data. While image reconstructor 230 is shown as a separate entity in FIG. 2 , in certain embodiments, image reconstructor 230 may form part of computing device 216. Alternatively, image reconstructor 230 may not be present in imaging system 200, and computing device 216 may perform one or more functions of image reconstructor 230. Furthermore, image reconstructor 230 may be located locally or remotely and operably connected to imaging system 200 using a wired or wireless network. In particular, in one exemplary embodiment, the computing resources of a “cloud” network cluster may be used for image reconstructor 230.

[0032] In one embodiment, image reconstructor 230 stores the reconstructed image in storage device 218. Alternatively, image reconstructor 230 may transmit the reconstructed image to computing device 216 for generating patient information useful for diagnosis and evaluation. In certain embodiments, computing device 216 may transmit the reconstructed image and / or patient information to a display or presentation device 232 communicatively coupled to computing device 216 and / or image reconstructor 230. In some embodiments, the reconstructed image is transmitted from computing device 216 or image reconstructor 230 to storage device 218 for short-term or long-term storage.

[0033] Although a CT system is described as an example, it should be understood that the present technology is applicable to other imaging modalities, including X-ray imaging systems, magnetic resonance imaging (MRI) systems, nuclear medicine imaging systems, positron emission tomography (PET) imaging systems, single photon emission computed tomography (SPECT) imaging systems, ultrasound imaging systems, and combinations thereof (e.g., multi-modality imaging systems such as PET / CT imaging systems or PET / MR imaging systems). This description of the CT imaging modality is provided merely as an example of a suitable imaging modality.

[0034] 3-5, various views of an example cradle clamp holder 300 are shown. FIG. 3 shows a first perspective view 380 of the cradle clamp holder 300. FIG. 4 shows a second perspective view 400 of the cradle clamp holder 300 of FIG. 3. FIG. 5 shows a side view 500 of the cradle clamp holder 300 of FIGS. 3-4. The cradle clamp holder 300 is an example of a support system 116 that can be attached to and coupled to a cradle 120 to reduce distortion of the cradle clamp holder 300 when the cradle clamp holder 300 is used to support an imaging subject such that the imaging subject protrudes from an end of the cradle (e.g., the first end 118 of the cradle 120). The cradle clamp holder 300 is self-centering with respect to the cradle and includes at least three leveling features that can be used to level the cradle clamp holder 300. The cradle clamp holder 300 will be simultaneously described with reference to Figures 3-5. Some elements may be visually shown in one or more of Figures 3-5, and some elements may be at least partially obscured in one or more of Figures 3-5.

[0035] A coordinate system 390 is shown that includes three axes (i.e., an x-axis parallel to the horizontal direction, a y-axis parallel to the vertical direction, and a z-axis perpendicular to the x-axis and y-axis). For reference, coordinate system 390 is shown in Figures 3-12. Cradle clamp holder 300 has a central axis 399 that lies in the xz plane. Cradle clamp holder 300 includes a first end 392 and a second end 396.

[0036] The cradle clamp holder 300 includes a platform 302. For example, the platform may be a flat body, a bar, or another type of elongated surface. The platform 302 may have an elongated rectangular shape. The platform 302 may have a first width 306 along a first length 304 of the elongated rectangular shape, which widens to a second width 308 along a second length 310. The platform 302 is a single, continuous body across the first length 304 and the second length 310. The platform 302 may be formed from a combination of metal, plastic, and / or rigid materials. The platform 302 may include one or more cutouts 312 extending through a thickness 314 of the platform 302. The one or more cutouts 312 may be provided to reduce the weight of the cradle clamp holder 300 while maintaining the structural integrity of the platform 302. The platform 302 further includes one or more through-holes 316 extending through a thickness 314 of the platform 302. The one or more through-holes 316 are located near a second end 396 of the cradle clamp holder 300 (and therefore of the platform 302). Additionally, the through-holes 316 are located near a first end 392 of the cradle clamp holder 300. Each through-hole 316 can be used to position a leveling feature of the platform 302, as described further herein.

[0037] In some examples, the platform 302 includes a level sensor 318. The level sensor 318 can be embedded and / or positioned on a flat surface 326 of the platform 302. The level sensor 318 can be a bubble level (e.g., a spirit level, a bull's eye level, or any other type of level that contains a liquid and a bubble and is used to indicate whether a surface (e.g., the platform 302) is horizontal or vertical). The level sensor 318 can be any type of spirit level (e.g., a digital level, a laser level, a water level, etc.). In some examples, the cradle clamp holder 300 can include multiple level sensors 318 embedded and / or positioned on a surface of one or more components of the cradle clamp holder 300. Furthermore, if multiple level sensors 318 are included, each level sensor can be the same or a different type of level sensor.

[0038] The platform 302 can further include verification lines 320 used to verify the position and / or level of the cradle clamp holder 300. For example, the verification lines can extend along the first length 304 and the second length 310 of the platform 302 and can extend along and / or parallel to the central axis 399. Additional verification lines 320 can extend perpendicular to the central axis 399. The verification lines 320 can be etched, burned, stamped, or otherwise cut into the flat surface 326 of the platform 302. In other examples, the verification lines 320 can be provided on the flat surface 326 using tape, markers, and / or another method that does not cut into the platform 302. With further reference to FIGS. 9-12 , the verification lines 320 can be aligned with alignment lines output by the imaging system to the cradle of the imaging system to aid in positioning and leveling the cradle clamp holder 300.

[0039] The cradle clamp holder 300 includes a first leveling member 322a and a second leveling member 322b, each of which includes a rod 324 that extends through the thickness 314 of the platform 302 perpendicular to a flat surface 326 of the platform 302. The position of the platform 302 along the length 328 of each rod 324 of the first leveling member 322a and the second leveling member 322b is independently adjustable, as described further herein. Because the first leveling member 322a and the second leveling member 322b have the same configuration, any description of the first leveling member 322a should be understood to also include a description of the second leveling member 322b, unless otherwise specified. The first leveling member 322a is shown in detail in and will be described with reference to FIG. 5. The first leveling member 322a can further include an adjustment head 502, a foot 504, and one or more fastening elements. The rod 324 includes a thread extending along a length 328 of the rod 324. The adjustment head 502 is fixedly coupled to the rod 324 at a first end 510 of the rod 324, such that rotation of the adjustment head 502 (e.g., clockwise and / or counterclockwise about the central axis 399) can rotate the rod 324 in the same direction. The foot 504 is fixedly coupled to the rod 324 at a second end 512 opposite the first end 392 of the rod 324. Rotation of the rod 324 (e.g., by rotation of the adjustment head 502) rotates the foot 504 in the same direction. In another example, the foot 504 can be coupled to the rod 324 such that rotation of the rod 324 does not rotate the foot 504. In some examples, the foot 504 can be coupled to the rod 324 to allow the foot 504 to tilt relative to the rod 324 and / or to allow the foot 504 to tilt relative to the surface on which the foot 504 is placed. For example, the foot 504 can be coupled to the rod 324 via a ball-and-socket joint that allows the foot 504 to rotate (pivot) relative to the rod 324. The foot 504 can include an engagement surface 514 formed of a cushioning or other non-abrasive material.For example, the engagement surface 514 can be formed of rubber, plastic, foam, fabric, or other non-abrasive material. As described further herein with respect to FIGS. 9-12 , the engagement surface 514 of the foot 504 can make surface contact with a surface of an imaging system cradle (e.g., the table 114 of the imaging system 100 of FIG. 1 ). The fastening elements of the first leveling member 322 a can be used to position the rod 324 perpendicularly relative to the flat surface 326 and other elements of the first leveling member 322 a. For example, the first fastening element 506 a can be disposed between the platform 302 and the adjustment head 502, and the second fastening element 506 b can be disposed between the platform 302 and the foot 504. These fastening elements can thus prevent the adjustment head 502 and the foot 504 from making surface contact with the platform 302.

[0040] 3 and 4, the rod 324 passes through a through-hole 316 in the platform 302. The through-hole 316 is configured with threads that complement (e.g., mate with) the threads of the rod 324, allowing the vertical position of the platform 302 in the direction of the length 328 of the rod 324 to be adjusted. For example, when the adjustment head 502 rotates clockwise, the rod 324 rotates clockwise. The platform 302 moves upward in the direction of the length 328 of the rod 324, thereby increasing the portion of the length 328 of the rod 324 that is below the platform 302. In other words, when the adjustment head 502 rotates clockwise, the rod 324 rotates clockwise, causing the rod 324 to move downward relative to the platform 302, increasing the portion of the length 328 of the rod 324 that is below the platform 302.

[0041] Rotating the adjustment head 502 of the first leveling member 322a can move the platform 302 in the direction of the length 328 of the rod 324 of the first leveling member 322a. For example, rotating the adjustment head 502 clockwise can move the first leveling member 322a (e.g., the rod 324, the first fastening element 506a, the second fastening element 506b, and the foot 504) downward relative to the platform 302, as shown by the first arrow 536 in FIG. 5 . As the first leveling member 322a moves downward relative to the platform 302, the portion of the length 328 of the rod 324 on the third side 520 (e.g., lower side) of the platform 302 increases, and the portion of the length 328 of the rod 324 on the fourth side 522 (e.g., upper side) of the platform 302 decreases. As further described with respect to Figures 9-13, by increasing the portion of the length 328 of the rod 324 below the platform 302, the vertical distance between the platform 302 and the surface on which the platform 302 is positioned (such as a cradle of an imaging system) can be increased.

[0042] An attachment plate 330 configured to support an imaging subject is coupled directly or indirectly to the platform 302 at a second end 396 opposite the first end 392 of the platform 302. For example, the attachment plate 330 can be directly coupled to the platform 302 by welding, brazing, or other bonding method, making the attachment plate 330 and the platform 302 a single, continuous part. In another example, the attachment plate 330 is indirectly coupled to the platform 302, for example, via one or more adjustment rods. The one or more adjustment rods can be removably attached to the platform 302 at a first end of the rod and to the attachment plate 330 at a second end of the rod. For example, the one or more adjustment rods can be attached to the platform 302 and the attachment plate 330 by a snap fit, a threaded attachment, and / or other removable attachment mechanism. The one or more rods can be replaceable, thereby allowing for adjustment. For example, a first rod set including one or more rods of a first length can be used to indirectly couple platform 302 to attachment plate 330. Platform 302 is thus spaced a distance equal to the first length from attachment plate 330 and coupled to attachment plate 330 by the first rod set. As described with respect to the first rod set, a second rod set including one or more rods having a second length different from the first length can be used to indirectly couple platform 302 to attachment plate 330. Platform 302 is thus spaced a distance equal to the second length from attachment plate 330 and coupled to attachment plate 330 by the second rod set. In some embodiments, the length of each of the one or more rods can be independently adjustable, such as by an extendable body of each of the one or more rods.Attachment plate 330 can have a variety of configurations that enable cradle clamp holder 300 to support an imaging subject via attachment plate 330 and / or via a mounting attachment selectively coupled to attachment plate 330, as will be further described with respect to Figures 6-8. In the example of Figures 3-5, attachment plate 330 includes a plurality of cutouts 332 and through-holes 334, which may be included to reduce the weight of cradle clamp holder 300 while maintaining the structural integrity of attachment plate 330. Cutouts 312 and through-holes 316 may also provide features for coupling a mounting attachment to attachment plate 330.

[0043] The cradle clamp holder 300 further includes a coupling clamp 340 at a first end 392 of the cradle clamp holder 300. The coupling clamp 340 is adjustable between a first position and a second position. The coupling clamp 340 can thus selectively couple the cradle clamp holder 300 to a surface (such as a cradle of an imaging system). The coupling clamp 340 includes a handle 356 that can be used to hold, carry, adjust, or position the cradle clamp holder 300. The coupling clamp 340 includes a support beam 344 having a first clamp 342 a and a second clamp 342 b. The support beam 344 is disposed perpendicular to the length 328 of the platform 302, and the first clamp 342 a and the second clamp 342 b are disposed on opposite sides of the platform 302 (e.g., a fifth side 350 and a sixth side 352 opposite the fifth side 350). Each of the first clamp 342a and the second clamp 342b is coupled to the support beam 344 at a pivot joint 346. Each of the first clamp 342a and the second clamp 342b is adjustable between a first position and a second position. The first clamp 342a and the second clamp 342b may be independently adjustable and / or may be adjustable using a single mechanism. By adjusting between the first and second positions, the first clamp 342a and the second clamp 342b can be used to clamp the cradle clamp holder 300 to a surface, such as a cradle of an imaging system, as described with respect to FIGS. 9-12. Because the first clamp 342a and the second clamp 342b have the same configuration, unless otherwise specified, any description of the first clamp 342a should be understood to also include a description of the second clamp 342b. First clamp 342a has a corner region 348 configured to contact the surface at a first angle and a flat region 354 configured to contact the surface at a second angle different from the first angle. As will be further described with respect to Figures 9-12, the surface may be a side and / or bottom surface of an imaging system cradle (e.g., cradle 120 of Figure 1).

[0044] The coupling clamp 340 is coupled to the platform 302 at a first end 392 of the platform 302. For example, a swivel joint 360 can selectively couple the coupling clamp 340 to the platform 302. The swivel joint 360 includes a head 362 that is fixedly coupled to the support beam 344 of the coupling clamp 340. The swivel joint 360 also includes a threaded extension 364 extending from the head 362. The threaded extension 364 receives an opening 366 in the platform 302 at the first end 392 of the platform 302. The opening 366 is positioned parallel to and / or axially aligned with a central axis 399 of the cradle clamp holder 300 and can be sized to be complementary to the threaded extension 364. Opening 366 includes threads that mate with the threads of threaded extension 364, such that swivel joint 360 threadably engages platform 302. Swivel joint 360 allows platform 302 to rotate about central axis 399 relative to coupling clamp 340. In other words, coupling clamp 340 is stationary (e.g., does not move relative to central axis 399) and platform 302 can tilt left and right relative to central axis 399, as indicated by arrow 368. In conjunction with adjustment of first leveling member 322a and second leveling member 322b, swivel joint 360 allows leveling of cradle clamp holder 300, as will be further described with reference to FIGS. 9-13.

[0045] The first leveling member 322 a, the second leveling member 322 b, and the swivel joint 360 are arranged in a Y-shape relative to the platform 302. The first leveling member 322 a and the second leveling member 322 b are axially aligned (e.g., along line 370), and the swivel joint is located between the members 322 a and 322 b along a central axis 399. The swivel joint 360 is located a distance away from the first leveling member 322 a and the second leveling member 322 b. For example, the swivel joint 360 is located toward the first end 392 of the platform 302, and the first leveling member 322 a and the second leveling member 322 b are located toward the second end 396 of the platform 302.

[0046] 6-8 show an example of a cradle clamp holder 300 having a mounting attachment 602 coupled to an attachment plate 330. Some elements of the cradle clamp holder 300 shown in FIGS. 3-5 may not be labeled and / or shown in FIGS. 6-8 for simplicity. FIG. 6 shows a first perspective view 600 of the cradle clamp holder 300 having the mounting attachment 602. FIG. 7 shows a second perspective view 700 of the cradle clamp holder 300 having the mounting attachment 602. FIG. 8 shows a side view 800 of the cradle clamp holder 300 having the mounting attachment 602. The cradle clamp holder 300 is described with respect to FIGS. 6-8, and some elements are visually shown in one or more of FIGS. 6-8 but may be at least partially invisible in one or more of FIGS. 6-8.

[0047] The mounting attachment 602 includes a shelf 604 having a planar surface 606 parallel to the platform 302 of the cradle clamp holder 300 and a back 608 perpendicular to and coupled to the shelf 604. The mounting attachment 602 may be a single piece in which the shelf 604 is continuous with the back 608. In the example of FIGS. 6-8 , the back 608 of the mounting attachment 602 includes a number of cutouts 632 extending through the thickness 314 of the back 608; these cutouts may be included to reduce the weight of the cradle clamp holder 300 while maintaining the structural integrity of the mounting attachment 602, and / or may be used to carry, hold, and / or position the mounting attachment 602 and / or cradle clamp holder 300. The mounting attachment 602 further includes a through-hole 634 extending through a thickness 638 of the spine 608, which can be used to couple the mounting attachment 602 to the attachment plate 330. For example, the mounting attachment 602 and the attachment plate 330 can each include one or more fastener through-holes 316. A fastener can be aligned with each fastener through-hole 316 in the mounting attachment 602 and the attachment plate 330, and inserted into each fastener through-hole 316 to couple the attachment plate 330 and the mounting attachment 602. In other examples, the mounting attachment 602 can be coupled to the attachment plate 330 via a clip-on, slide-in, or other selective coupling mechanism (which includes a first portion of the mounting attachment 602 and a second portion of the attachment plate 330 configured to engage the first portion). The mounting attachment 602 may, in some cases, be fixedly coupled to the attachment plate 330 by, for example, welding and / or by being formed as a single, continuous element with the attachment plate 330 .In other examples, the mounting attachment 602 can be removably coupled to the attachment plate 330, for example, via one or more removable fasteners. In the example of FIGS. 6-8, the mounting attachment 602 is coupled to the attachment plate 330 at the back 608. The mounting attachment 602 can further include one or more cutouts 312 in the sides of the shelf 604, where the shelf 604 is hollow and the cutouts 632 in the shelf 604 provide access to the hollow interior of the shelf 604. The mounting attachment 602 can have other shapes and / or dimensions than those shown in FIGS. 6-8, and variations of the mounting attachment 602 can be fixedly and / or selectively coupled to the attachment plate 330 and configured to support one or more imaging subjects.

[0048] When the mounting attachment 602 is coupled to the attachment plate 330, movement of the platform 302 is translated into movement of the mounting attachment 602. For example, adjusting one or more of the first leveling member 322a and the second leveling member 322b to adjust the vertical position of the platform 302 also adjusts the vertical position of the mounting attachment 602, as described with respect to FIG.

[0049] The coupling clamp 340 is configured to engage an imaging system cradle to center the cradle clamp holder 300 relative to the cradle and secure the position of the platform 302 relative to the cradle. The first leveling member 322a, the second leveling member 322b, and the swivel joint 360 are configured to adjust the level of the cradle clamp holder 300 when the cradle clamp holder 300 is positioned in the cradle. FIGS. 9-12 show an example of the cradle clamp holder 300 of FIGS. 3-8 positioned in and coupled to a cradle 910 of an imaging system. The cradle 910 may be an example of the cradle 120 of the imaging system 100 of FIGS. 1-2. FIGS. 9-11 show the cradle clamp holder 300 without the mounting attachment 602, while FIG. 12 shows the cradle clamp holder 300 with the mounting attachment 602. For the sake of brevity, some components of the cradle clamp holder 300 introduced in Figures 3 to 8 may not be numbered and / or may not be shown again in Figures 9 to 12.

[0050] 9 shows a perspective view 900 of the cradle clamp holder 300 coupled to a cradle 910. The cradle 910 includes a compressible side runner 912 extending from a first side 902 of the cradle 910 and a compressible side runner 912 extending from a second side 904 opposite the first side 902. The compressible side runner 912 may be formed from a compressible material (such as foam, rubber, and / or other material that deforms in response to an applied force and returns to its original shape when the force is removed). The cradle clamp holder 300 is positioned on the cradle 910, with the sixth side 352 adjacent to and parallel to the first side 902 of the cradle 910, and the fifth side 350 of the cradle clamp holder 300 adjacent to and parallel to the second side 904 of the cradle 910.

[0051] The cradle clamp holder 300 can be positioned on the cradle 910 using different methods. In some embodiments, the cradle clamp holder 300 includes a clamp lock 906 coupled to each of the first clamp 342a and the second clamp 342b, and when each clamp lock 906 is in a first position (e.g., the position shown in FIG. 9 ), each of the first clamp 342a and / or second clamp 342b can prevent adjustment of the clamp position between the first and second positions of the respective clamp. When the first clamp 342a and the second clamp 342b are in the first position, a distance 914 between the flat region 354 of the first clamp 342a and the flat region 354 of the second clamp 342b can be shorter than a surface length 916 of the cradle 910. This prevents the cradle clamp holder 300 from lowering into the position of the cradle 910 (e.g., moving downward parallel to the y-axis). The clamp lock 906 of each of the first clamp 342a and the second clamp 342b can be adjusted to a second position, causing the first clamp 342a and the second clamp 342b to rotate about their respective pivot joints 346 to a second position and increasing the distance 914 between the flat area 354 of the first clamp 342a and the flat area 354 of the second clamp 342b. The distance 914 may be increased to be longer than a surface length 916 of the cradle 910. Thus, the cradle clamp holder 300 can be lowered onto the cradle 910 and / or slid toward the cradle 910 in a direction parallel to the z-axis. Once the cradle clamp holder 300 is positioned on the cradle 910, the first clamp 342a and the second clamp 342b can be adjusted to the first position, shortening the distance 914 between the flat areas 354 of the clamps. Thus, the first clamp 342 a and the second clamp 342 b can clamp the surface 920 of the cradle 910 and hold the cradle clamp holder 300 in place relative to the cradle 910 .In another example, the cradle clamp holder 300 does not include the clamp lock 906, but instead the pivot joint 346 is spring-loaded, which can extend the distance 914 to allow the cradle clamp holder 300 to be placed on the cradle 910, and the spring bias of the pivot joint 346 can clamp the cradle clamp holder 300 to the cradle 910. In another embodiment, the cradle clamp holder 300 can include a screw tightening mechanism that allows the first clamp 342 a and the second clamp 342 b to be adjusted and / or prevents the first clamp 342 a and the second clamp 342 b from being adjusted. For example, instead of including the clamp lock 906 on the support beam 344, a screw tightening mechanism can be included on the support beam 344. The screw tightening mechanism can be adjusted between a first position and a second position, where the first position allows each of the first clamp 342 a and the second clamp 342 b to move freely and where the second position prevents each of the clamps from moving. For example, the screw tightening mechanism may include a threaded extension that penetrates the support beam 344 (e.g., parallel to the y-axis) at and / or near the pivot joint 346 of each clamp. The threaded extension may contact the pivot joint 346 when the screw tightening mechanism is in the second position, thereby preventing movement of the pivot joint 346. When the screw tightening mechanism is in the first position, the threaded extension may not contact the pivot joint 346, thereby allowing movement of the pivot joint 346. In some embodiments, a single screw tightening mechanism may be used to control both the first clamp 342 a and the second clamp 342 b. As further described with respect to FIG. 10 , a corner region 348 of each of the first clamp 342 a and the second clamp 342 b may contact a compressible side runner 912.

[0052] FIG. 9 shows the foot 504 of each of the first and second leveling members 322a and 322b contacting a surface 918 of the cradle 910. The engagement surface 514 of the foot 504 prevents the foot 504 from sliding against the surface 918. As will be further described with respect to FIGS. 10-13, once the cradle clamp holder 300 is positioned on the cradle 910, it may be desirable to adjust the vertical position of the platform 302 of the cradle clamp holder 300. Adjustment of the vertical position of the platform 302 may be achieved by adjusting one or more of the first and second leveling members 322a and 322b. Additionally, the swivel joint 360 of the coupling clamp 340 aids in leveling the cradle clamp holder 300 relative to the cradle 910.

[0053] FIG. 10 shows a front view 1000 of the cradle clamp holder 300 coupled to a cradle 910. As described with respect to FIG. 9 , the flat region 354 of each of the first clamp 342 a and the second clamp 342 b is in surface contact with the surface 920 of the cradle 910. The corner region 348 of each of the first clamp 342 a and the second clamp 342 b is in surface contact with the compressible side runner 912 of the cradle 910. When the clamp lock 906 of each of the first clamp 342 a and the second clamp 342 b is in the first position (e.g., as shown in FIG. 10 ), the first clamp 342 a and the second clamp 342 b can at least partially compress the compressible side runner 912, thereby allowing the flat region 354 of each clamp to be in full surface contact with the respective surface 920 of the cradle 910. In this manner, the coupling clamp 340 uses the first clamp 342a and the second clamp 342b to self-position the cradle clamp holder 300 relative to the cradle 910. The coupling clamp 340 can resist deflection of the cradle clamp holder 300 from the cradle 910 when an imaging subject is supported so that it protrudes from the end of the cradle 910, as will be further described with respect to FIGS.

[0054] Referring to Figure 11, a perspective view 1100 of the cradle clamp holder 300 coupled to the cradle 910 of an imaging system 1102 is shown. The imaging system 1102 may be an example of the imaging system 100 of Figures 1-2, and is shown in partial view in Figure 11. Figure 11 shows the gantry 1104 of the imaging system 1102. The cradle 910 is partially inserted into the gantry 1104 for imaging, and the second end 396 of the cradle clamp holder 300 (and thus the attachment plate 330) is inserted into the gantry 1104. It should be understood that the mounting attachment 602 can be coupled to the attachment plate 330 as described with reference to Figures 6-8, and thus the mounting attachment 602 can also be inserted into the gantry 1104.

[0055] The imaging system 1102 has a laser alignment line 1120. The laser alignment line 1120 is projected onto the interior of the gantry 1104 and can be used to align the cradle clamp holder 300 with respect to the cradle 910. For example, the laser alignment line 1120 can be projected onto the cradle 910, and the verification line 320 can be aligned with the laser alignment line 1120 to place the cradle clamp holder 300 in a desired position on the cradle 910. The level sensor 318 can also be used to adjust the level of the cradle clamp holder 300. For example, one or more of the first leveling member 322 a, the second leveling member 322 b, and the swivel joint 360 can be adjusted to adjust the vertical position of the cradle clamp holder 300 so that the bubble of the level sensor 318, configured as a bubble level, is centered on the level sensor 318.

[0056] FIG. 12 shows a perspective view 1200 of a phantom 1202 supported by the mounting attachment 602 of the cradle clamp holder 300. The cradle clamp holder 300 is coupled to the cradle 910. The mounting attachment 602 shown in FIG. 12 is configured with a shelf 604, as described with respect to FIGS. 6-8, and the phantom 1202 is positioned on the shelf 604. In some examples, a patient (such as an infant and / or child) and / or an extremity of an adult patient can be positioned on the mounting attachment 602 rather than the phantom 1202. In other examples, the mounting attachment 602 can have another configuration capable of supporting an imaging subject. For example, the mounting attachment 602 can include a U-shaped, cylindrical, and / or other cradle-shaped support. Because the mounting attachment 602 protrudes from the first end 1204 of the cradle 910 , the cradle clamp holder 300 supports the imaging subject (eg, the phantom 1202 ) beyond the first end 1204 of the cradle 910 .

[0057] 13 shows a flowchart of a method 1300 for positioning a cradle clamp holder in a cradle of an imaging system. The method 1300 will be described with reference to the cradle clamp holder 300 of FIGS. 1-12. The cradle of the imaging system may be an example of the cradle 120 of the imaging system 100 of FIG. 1.

[0058] In step 1302, method 1300 includes positioning a cradle clamp holder on a cradle of an imaging system. The cradle clamp holder can be slid horizontally onto the cradle from a first end of the cradle. The first and second clamps of the coupling clamps are adjustable (e.g., by unlocking clamp locks and / or by spring joints) at their respective pivot points so that the cradle clamp holder can be positioned on the cradle. In another example, the cradle clamp holder can be lowered vertically onto the cradle. The cradle clamp holder can be positioned so that the attachment plate and the mounting plate extend from the first end of the cradle. In some embodiments, a back surface of the attachment plate (e.g., a side of the attachment plate opposite a front surface where the attachment plate is coupled to the mounting plate) abuts the first end of the cradle.

[0059] In step 1304, method 1300 includes leveling the platform of the cradle clamp holder by adjusting the vertical position of the platform using at least one leveling member of the cradle clamp holder. With respect to cradle clamp holder 300 of FIGS. 3-12 , the adjustment head of the first leveling member can be rotated in a clockwise direction to raise the vertical position of the platform on the rod of the first leveling member, thus increasing the vertical distance between the platform and the cradle. Additionally or alternatively, the adjustment head can be rotated in a counterclockwise direction to lower the vertical position of the platform on the rod of the first leveling member, thus decreasing the vertical distance between the platform and the cradle. The second leveling member can be adjusted in a similar manner. The first and second leveling members are independently adjustable, and thus, adjusting the first leveling member can adjust the vertical position of the platform on the fifth side of the cradle clamp holder. Adjusting the first leveling member does not adjust the vertical position of the platform on the sixth side of the cradle clamp holder. Because the platform is a single piece, adjusting one of the first and second leveling members allows the platform to rotate about the central axis of the cradle clamp holder via a swivel joint. The first and second leveling members can be adjusted independently by rotating their respective adjustment heads to level the platform. The platform can be determined to be level using a level sensor (such as a bubble level) on the cradle clamp holder.

[0060] In step 1306, method 1300 includes centering the cradle clamp holder relative to the cradle by adjusting the combined clamp from a second open position to a first closed position. For example, a clamp lock of each of the first and second clamps can be adjusted from an open position to a closed position (e.g., a locked position), where the open position allows each clamp to rotate (pivot) about its respective pivot joint, and the closed position prevents the clamp from rotating. If the pivot joints of the first and second clamps are configured with springs, the first and second clamps can automatically tighten when the cradle clamp holder is positioned on the cradle, thereby allowing the cradle clamp holder to self-center on the cradle.

[0061] 3 through 12 illustrate exemplary arrangements of various components relative to one another. Where elements are shown as being in direct contact with or directly coupled to one another, they can, in at least one example, be said to be in direct contact with or directly coupled to one another. Similarly, elements shown as being contiguous or adjacent to one another can, in at least one example, be said to be contiguous or adjacent to one another, respectively. As an example, components in surface contact with one another can be said to be surface contacting components. As another example, elements positioned apart from one another, with only a space between them and no other components present, can, in at least one example, be said to be such. As yet another example, elements shown above and below one another, opposite one another, or left and right of one another can be said to be such relative to one another. Furthermore, as shown in the figures, in at least one example, a top element or point on that element can be said to be the “top” of a component, and a bottom element or point on that element can be said to be the “bottom” of a component. As used herein, terms such as "top / bottom," "above / below," and "above / below" are relative to the vertical axis of the figure and can be used to describe the placement of elements of the figure relative to one another. For example, if an element is shown above another element, the element is, by way of example, vertically disposed above the other element. As yet another example, the shapes of elements shown in the figures can be referred to as having that shape (e.g., circular, rectilinear, planar, curvilinear, rounded, chamfered, angled, etc.).
