A method includes receiving data acquired with a light detection and ranging (LiDAR) scanning system physically coupled to a computed tomography (CT) imaging system of a subject to be imaged disposed on a cradle of a table, wherein the table is configured to move the subject into and out of a bore of a gantry of the CT imaging system. The method also includes generating a multi-dimensional avatar of the subject representing a topography of the subject. The method further includes causing display of the multi-dimensional avatar positioned on the cradle that represents a current position of the subject on the display, wherein the display is disposed adjacent the table within view of the subject. The method even further includes providing instructions on the display to enable the subject to guide themselves to a target position on the cradle for a CT scan with the CT imaging system.

Various methods and systems are provided for an imaging subject support system for an imaging system. The imaging subject support system may be a cradle clamping holder comprising: a platform; at least one leveling member, each of which includes at least one rod; a coupling clamp that is coupled to the platform at a first end of the platform, and where the coupling clamp is adjustable between a first position and a second position; and an attachment plate configured to support an imaging subject, the attachment plate directly or indirectly coupled to the platform at a second end of the platform, opposite the first end.

A head-stabilizing apparatus is adapted to position a head of a patient undergoing a medical procedure. The head-stabilizing apparatus includes a patient locator and a patient mask. The patient locator includes a mouthpiece adapted to be placed in a mouth of the patient undergoing the medical procedure. The patient mask is configured to change between an unworn position in which the patient mask is spaced apart from the face of the patient and an patient-worn position in which the patient mask overlays the face of the patient and receives the head of the patient undergoing the medical procedure. The patient locator is configured to selectively couple with the patient mask.

A system and method for a lidar guided patient positioning are described. An example imaging system includes a gantry having a bore, a table to move a subject relative to the bore, a radiation source mounted on the gantry and to emit an X-ray beam, and a detector to detect the X-ray beam. The system further includes a light detection and ranging (LiDAR) scanning system to acquire data of the subject. The system further includes processing circuitry to process the LiDAR data to generate a 3D point cloud representing a topography of the subject, estimate a center of a region of interest of the subject, calculate an offset of the center of the region of interest relative to an isocenter of the gantry, and adjust a height of the table based on the offset to align the center of the region of interest with the isocenter of the gantry.

One or more example embodiments relates to a support structure for supporting an examination object in a pediatric computed tomography examination. The support structure includes a bearing surface for the examination object; a first side wall; and a second side wall, wherein the bearing surface, the first side wall and the second side wall in each case extend flat along a longitudinal axis of the support structure, and the first side wall and the second side wall protrude relative to the bearing surface such that the examination object is placeable on the bearing surface between the first side wall and the second side wall.
