A support system configured to support the lower extremities of a patient, for example during radiotherapy and imaging procedures, and methods for employing the same is provided. The support system includes a knee support apparatus and a foot support apparatus, each of which may be used together or independently in order to customize the support needed for the particular procedure. When used on the patient table of an appropriate imaging or treatment modality, the support system is configured to allow the clinician to independently adjust the knee support and foot support's positioning in the superior-inferior axis of the patient table in both a gross and fine manner for optimal positioning of the patient for the target procedure. The robust adjustment capabilities of the support system enable enhanced patient comfort, setup reproducibility, and workflow efficiency.

A method is for providing a medical image of a patient, acquired via a computed tomography apparatus. An embodiment of the method includes acquiring first projection data of a first measurement region; acquiring second projection data of a second measurement region; registering a reference image to the at least one respiration-correlated image of the patient, wherein the reference image corresponds to the at least one functional image of the patient or is reconstructed under a second reconstruction rule from the second projection data, to produce a deformation model; applying the deformation model to the at least one functional image of the patient; combining the at least one functional image of the patient, deformed by the applying of the deformation model, with the at least one respiration-correlated image of the patient, to produce the medical image of the patient; and providing the medical image of the patient.

Disclosed is apparatus and method for motion tracking of a subject in medical brain imaging. The method comprises providing a light projector and a first camera; projecting a first pattern sequence (S1) onto a surface region of the subject with the light projector, wherein the subject is positioned in a scanner borehole of a medical scanner, the first pattern sequence comprising a first primary pattern (P.sub.1,1) and/or a first secondary pattern (P.sub.1,2); detecting the projected first pattern sequence (S1′) with the first camera; determining a second pattern sequence (S2) comprising a second primary pattern (P.sub.2,1) based on the detected first pattern sequence (S1′); projecting the second pattern sequence (S2) onto a surface region of the subject with the light projector; detecting the projected second pattern sequence (S2′) with the first camera; and determining motion tracking parameters based on the detected second pattern sequence (S2′).

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 longitudinal-positioning indicator, improved marking grid, and a method of use. The longitudinal-positioning indicator includes a substrate that has a first side on which a set of longitudinal-positioning guidelines are disposed, the set of longitudinal-positioning guidelines configured to indicate a position along a length of the longitudinal-positioning guidelines based on a cross-section of the longitudinal-positioning indicator taken substantially orthogonally to the set of longitudinal-positioning guidelines. The substrate also has a second side that is at least partially coated with an adhesive.

The invention comprises a substance suitable for external marking of a patient's skin during a radiographic procedure, such as angiography and endovascular procedures. The substance comprises a volume of radiopaque marking substance suitable for creating a rapidly stable and precise image on a radiographic medical device when said material is placed externally on a patient and imaged by the radiographic medical device. The substance comprises a volume of forming material for combination with the radiopaque material. An associated dispenser is also disclosed.

The present disclosure relates to the generation of partial surface models from volumetric datasets for subsequent registration of such partial surface models to surface topology datasets. Specifically, given an object that is imaged using surface topology imaging and another volumetric modality, the volumetric dataset is processed in combination with an approach viewpoint to generate one or more partial surfaces of the object that will be visible to the surface topology imaging system. This procedure can eliminate internal structures from the surfaces generated from volumetric datasets, thus increases the similarity of the dataset between the two different modalities, enabling improved and quicker registration.

A head stabilization system including a head restraint mechanism and a head harness configured to engage a head of a patient. The head restraint mechanism is configured to be operatively disposed on a patient support device and includes a generally vertically upstanding arcuate tilt guide. The head harness is releasably attachable to and at least partially supported by the head restraint mechanism. The head harness is selectively repositionable generally vertically relative to the tilt guide. The head restraint mechanism is configured to stabilize the head harness relative to the patient support device. The head restraint mechanism is configured to selectively allow lateral flexion of a neck of the patient, lateral rotation of the head of the patient, and extension and flexion of the neck of the patient.

The invention relates to a position indicator for a system for moving a patient in a non-invasive therapy system, wherein the system for moving includes a patient support arranged outside a treatment space of a medical apparatus of the non-invasive therapy system, a treatment table arranged inside the treatment space in the medical apparatus, and a patient bed movable in a longitudinal direction from the patient support to the treatment table and back by means of activation of a transferring mechanism, wherein the position indicator comprises a number of light emitting elements arranged in the patient support and each being arranged to receive activation signals instructing a receiving light emitting element to emit light to indicate positions for treatment equipment.
