Abstract: A self-shielded and computer controlled system for performing non-invasive stereotactic radiosurgery and precision radiotherapy using a linear accelerator mounted within a two degree-of-freedom radiation shield coupled to a three-degree of freedom patient table is provided. The radiation shield can include an axial shield rotatable about an axial axis and an oblique shield independently rotatable about an oblique axis, thereby providing improved range of trajectories of the therapeutic and diagnostic radiation beams. Such shields can be balanced about their respective axes of rotation and about a common support structure to facilitate ease of movement. Such systems can further include an imaging system to accurately deliver radiation to the treatment target and automatically make corrections needed to maintain the anatomical target at the system isocenter.

Abstract: An array of force sensors for determining a position of an object, detecting motion of object, and tracking motion of objects in 3D space are described herein. In particular, an array of force sensors can be used to monitor anatomical motion during medical procedures, such as head motion during cranial radiosurgery, to maintain a desired alignment with the anatomical feature. Alerts can be posted to the medical machine operator and the radiosurgery system or scanner can make compensatory adjustments to maintain the desired alignment either after suspension of treatment or dynamically during treatment. Methods of detecting a position, movement or tracking motion of an anatomical feature are also provided herein.

Abstract: Methods and systems are provided useful in various procedures, including hair harvesting and implantation, and further including computer-implemented and/or robotic hair transplantation. Methodologies are provided which enable a tool, such as a hair harvesting or a hair implantation tool, to proceed at least under a partial computer control in a selected direction of travel along a donor or recipient area of the patient, as well as changing direction of travel based on desired harvesting and/or implantation criteria.

Abstract: Devices and methods that allow a user to elect between performing treament planning by inverse planning or to be accomplished by utilizing one or more parameters input that are typically associated with forward planning are described herein. The systems can be configured to produce a treatment plan in a single iteration upon initiation of treatment planning or in response to determining or receiving a target geometry. While the system may be used iteratively in an extensively interactive fashion, viable inverse plans can be generated with a single user interaction, such as a single click, or optionally with no click at all. Advantageously, the system can optionally allows a clinnician to add or adjust parameters or constraints, for example in another iteration, to provide additional autonomy if desired.

Abstract: Systems and methods for creating a treatment plan for cosmetic procedures are provided. The treatment plan automatically modifies or generates one or more proposed sites within a first body surface element based on one or more parameters in one or more second body surface elements. Various techniques and methods described in the application provide for improved planning of a procedure.

Abstract: Methods and systems are provided useful in various procedures, including hair harvesting and implantation, and further including computer-implemented and/or robotic hair transplantation. Methodologies are provided which enable selection of follicular unit harvesting or implanting sites within the same row in a direction of travel of the tool, or by incrementing to another row. In various cases, such selection may be made using a lowest and closest method, overlap-based methods, position-based methods, pattern-based methods, and/or a combination of these methods. In various combinations of the methods, the output selection from one of the methods may be used as an input for one of the other methods.

Abstract: Methods and systems are described for hair transplantation and other surgical procedures on a body surface. Specifically, methods and systems for computer-implemented and/or robotic hair transplantation and other surgical procedures, using time constrained image processing techniques are described. In various examples, multiple images of a body surface may be divided into overlapping sub regions for comparison. In various other cases, a percentage of an image of a body surface to be processed may be adjusted based on a time constraint. In some implementations, the output of one of these methods may be used as input for the other method.
