Systems and methods and for identifying a mechanical axis of a bone may include identifying an orientation of an intercondylar feature on the bone, projecting a plane based on the orientation of the intercondylar feature, and identifying the orientation of the mechanical axis of the bone based on the plane. The plane may contain at least a portion of the intercondylar feature and the mechanical axis of the bone therein.

Various embodiments of an emitter-aligned surgical guide and methods of use are disclosed. The emitter-aligned surgical guide includes a body extending between a first surface and a second surface. The body defines at least one hole extending from the first surface to the second surface. At least one alignment jig is coupled to the second surface. The at least one alignment jig includes a jig arm extending from a first end coupled to the second surface of the body to a second end and an emitter support configured to couple an emitter device to the at least one alignment jig in a predetermined position relative to the body.

A surgical suturing tracking system is disclosed. The surgical suturing tracking system is configured to detect and guide a suturing needle during a surgical suturing procedure. The surgical suturing track system comprises a control circuit configured to predict a path of a needle suturing stroke after receiving an input from a clinician, detect an embedded tissue structure, and assess proximity of the predicted path and the detected embedded tissue structure.

An ultrasound probe is guided to an optimal position on a patient's body by illuminating the patient's body with a laser, by displaying icons of the probe position and the optimal position on a 3-D model of the patient's body, or by playing an audio signal that varies according to distance of the probe position from the optimal position. In certain embodiments, the probe is guided to a series of optimal positions for conducting a vascular exam, responsive to a database of human anatomy and vasculature and responsive to a database of vascular exam procedures.

A method of analysis using mass spectrometry and/or ion mobility spectrometry is disclosed. The method comprises: using a first device to generate smoke, aerosol or vapour from a target comprising or consisting of a microbial population; mass analysing and/or ion mobility analysing said smoke, aerosol or vapour, or ions derived therefrom, in order to obtain spectrometric data; and analysing said spectrometric data in order to analyse said microbial population.

The present disclosure relates to a system and method for locating a target subject associated with an X-ray system. The X-ray system may include an X-ray source, a detection component, an arm, and a platform. The X-ray system may also include a first positioning component, a second positioning component, or a third positioning component. The first positioning component may be configured to determine a target point where a region of interest (ROI) of the target subject locates. The second positioning component may be configured to locate the target subject. The third positioning component may be configured to obtain location information of a target device associated with the target subject in real-time.

A medical movable body system according to the present disclosure includes a medical movable body, a robot, a manipulator, and a controller. The robot is in a first space. The manipulator is in a second space. The controller executes: (A) making the robot self-travel to approach a patient; and after the (A), (B) operating an arm and/or a hand .

An instrument, a magnetic resonance imaging scanner and a method for operating the magnetic resonance imaging scanner with the instrument in which the instrument is aligned with a patient. The medical instrument comprises a first projector for projecting a luminous pointer in a predetermined alignment relative to the medical instrument. The magnetic resonance imaging scanner comprises a positioning aid configured to mark a predetermined position on an inner wall of a patient tunnel in a manner that is visible to a user. In the method, a predetermined alignment of the first projector relative to the medical instrument or position of the positioning aid on the wall of the patient tunnel is ascertained in which the luminous pointer of the first projector coincides with the positioning aid when the medical instrument is aligned parallel to a trajectory through an entry point on the patient and a target point in the patient and the medical instrument is aligned such that the luminous pointer and the positioning aid coincide.
