A trajectory is determined for inserting a patient into an MR scanner. An avatar representing specific body dimensions is provided. The avatar includes location information relating to an implant. A spatial magnetic field gradient data set relating to the scanner is provided. An avatar pose at a starting point of the trajectory is defined, and a course for the trajectory is provided. For several points on the trajectory, the corresponding magnetic field value are determined by combining the spatial magnetic field gradient data set with the avatar pose. The trajectory and/or the avatar pose are determined so that the at least one implant only passes regions within the MR scanner that are below a predetermined threshold value concerning the magnetic field gradient.

Systems and method for optical imaging of an animal include a body conforming animal mold, which is shaped and sized to hold an animal in an immobilized and geometrically defined position and a gantry, which can include multiple optical mirrors to provide for simultaneous imaging of multiple different views of an animal within a body conforming animal mold.

A method is described for positioning of an examination object for an imaging method. The method is used to record an external image of externally visible features of the examination object. The recording of the external image is used as the basis for determining a position and/or orientation of at least one part of the examination object assigned to the imaged features. Subsequently, a check is performed as to whether the determined position and/or orientation of the at least one part of the examination object conforms to a reference position and/or reference orientation. Finally, if the determined position and/or orientation of the at least one part of the examination object does not conform to the reference position and/or reference orientation, the position and/or orientation of the at least one part of the examination object is corrected. Also described is an object-positioning facility. Furthermore, an imaging medical facility is described.

According to an aspect there is provided a method of determining a calibration parameter for a first blood pressure, BP, measurement device, the method comprising obtaining a first physiological characteristic measurement of a subject using the first BP measurement device, wherein the first BP measurement device is for obtaining physiological characteristic measurements of a physiological characteristic of the subject and for determining a BP measurement of the subject from the physiological characteristic measurements using the calibration parameter, wherein the first physiological characteristic measurement is obtained when a torso of the subject is in a first posture; obtaining a second physiological characteristic measurement of the subject using the first BP measurement device, wherein the second physiological characteristic measurement is obtained when the torso of the subject is in a second, different, posture; determining the change in the posture of the torso from the first posture to the second posture; estimating a change in BP of the subject or a change in the physiological characteristic of the subject from the determined change in the posture of the torso; and determining the calibration parameter for determining BP measurements from physiological characteristic measurements obtained by the first BP measurement device from an analysis of the first physiological characteristic measurement, the second physiological characteristic measurement and the estimated change.

An optical measurement system includes a wearable device configured to be worn on a body of a user and a position alignment system. The wearable device includes a support assembly and a wearable assembly supported by the support assembly. The wearable assembly includes a plurality of light sources configured to emit a plurality of light pulses toward a target within the body of the user and a plurality of detectors each configured to receive a set of photons included in a light pulse included in the plurality of light pulses after the set of photons is scattered by the target. The position alignment system is configured to facilitate positioning of the wearable assembly at a same position on the body of the user during different use sessions of the wearable device.

A transport apparatus may include a patient bed unit for supporting the patient; a transferring unit for moving the patient bed unit along a first direction of the MRI device; and an elevating module for moving the patient bed unit along a second direction of the MRI device.

The present disclosure directs to a system and method for automated positioning of a subject. The method may include obtaining a scout image of a subject when the subject is positioned at a first position in an apparatus. The method may also include determining location information of a reference structure of the subject based on the scout image. The method may also include determining an offset between the first position of the subject relative to a characteristic point of the apparatus according to the location information of the reference structure. The method may further include moving the subject to a second position based on the offset. The method may still further include performing, using the apparatus, a procedure relating to a target structure of the subject located at the second position.

Described herein are systems and methods of processing immobilization molds for application of treatment, A computing system may generate a three-dimensional mold model of immobilization mold within with a subject is to be positioned for application of a treatment. The computing system may subtract a three-dimensional scan of at least a portion of the subject from the three-dimensional mold model to define an opening therein. The computing system may remove, from the three-dimensional mold model, a first portion to define an imprint in the opening from a first axis along which the subject is to enter. The computing system may remove, from a second portion of the three-dimensional mold model remaining with the removal of the first portion, inward protrusions into the imprint of relative to the second axis intersecting the first axis.

The invention describes a measuring system for the continuous non-invasive determination of blood pressure at one or more fingers. The fingers chosen for measurement and the adjacent parts of the palm rest on a supporting surface of a housing, which has the shape of a computer mouse. Inside the housing of the “CNAP Mouse”, i.e. underneath the supporting surface for the hand, the pressure generating system is located. The finger sensors are mounted on the supporting surface for the hand. The forearm and the back of the hand are left free and may be used to place intra-venous or intra-arterial access elements. Since the hand will rest on the supporting surface motion artefacts are largely avoided. Tilting or turning of the sensors is hardly possible since the fit of the sensors and thus the coupling of light and pressure are optimized.

The patient couch (1) serves for carrying out radiological medical imaging examinations by X-ray, tomography, nuclear magnetic resonance and other imaging methods. The person rests thereon in lying position for the creation of tomographic and other images. The patient couch is equipped with a capturing device, for measuring the patient's body or certain sites of the patient's body by optical, laser-optical, mechanical or electromechanical methods and/or devices. The couch has footrests for positioning the soles of the feet as when standing on vertical supporting faces with natural spreading of the feet, as well as portions for capturing at least the positions of the knee joints, the hip joint, the pelvic bone, the shoulders and the head. Further, the couch is equipped with pressure sensors for measuring the local supported weights of the various supported body sites, for reproducibly capturing the position of the skeleton with regard to its center axis as well as any rotations of shoulder and/or hip.
