The invention relates to an orthodontic diagnostic method wherein at least one initial two-dimensional X-ray image (1) of a first zone (2) of a head (3) is taken. Then at least one three-dimensional X-ray image (4) of a second zone (5) of a dental situation is taken, and the three-dimensional X-ray image (4) is combined with the initial two-dimensional X-ray image (1) using a registration process in order to obtain a full image (8).

Methods and devices are disclosed for the tomographic imaging of a biological sample from almost all rotational perspectives in three-dimensional space and with multiple imaging modalities. A biological sample is positioned on an imaging stage that is capable of nearly full 360-degree rotation in at least one of two substantially orthogonal axes. Positioned about the stage is an X-ray imaging module enabling the recording of a series of images. A reflected light imaging module can also be positioned about the stage to enable recording of black and white or color white light images. A computer can use the images to construct three-dimensional models of the sample and to render images of the sample conveying information from one or more imaging channels.

A displacement mechanism for placing an optical device onto a patient's eyes and removing the optical device from the patient's eyes when the patient is located in a patient bore of a medical imaging system. The mechanism includes a pneumatic device and a resilient element attached between an inner surface of the patient bore and the optical device wherein the resilient element extends through the pneumatic device and wherein the optical device is spaced apart from the patient's eyes in a first position. A pump inflates the pneumatic device to move the optical device to a second position wherein the optical device is placed on the patient's eyes. Inflation of the pneumatic device extends the resilient element and biases the resilient element to return to the first position. A vent valve vents air from the pneumatic device to return the optical device to the first position.

The present invention relates to a phantom for quality assurance of magnetic resonance imaging (MRI) and computed tomography (CT) for multi-artifact correction. An aspect of the present invention provides a phantom capable of simultaneously evaluating performance of magnetic resonance imaging (MRI) and computed tomography (CT), the phantom including: a first hemispheric container; and a second hemispheric container which has the same structure and the same size as the first container, in which the first container and the second container are connected by being in direct contact with each other so as to form a symmetrical structure, each of the first container and the second container includes a teeth retainer into which a plurality of teeth mimics, which mimics teeth of a body, is inserted, and an insertion hole into which at least one bone mimic is inserted, and an interior of each of the first container and the second container is filled with at least one solution that mimics a brain metabolite.

The present disclosure addresses above-mentioned issues by providing a system and method for preparing a correlation data set to be used in parametric grading of malignant tissues. Systems and methods of the present disclosure further provide for a visualization scheme, wherein all the parameters can be viewed at the same time and processed together to arrive at an accurate grading of the tissue based on threshold based comparison of the parameter values for each voxel.

The present invention provides an ergonomic operational system and method thereof for a human operator such as a dental surgeon in image guided implantation. A physical or virtual display in close proximity to, or integrated with, the dental drill shows the information that demands a high frequency of observation from the surgeon. The surgeon is thus able to monitor the drilling site and the display at the same time, without moving his head toward other display not within his field of view. The invention exhibits numerous technical merits such as simplicity of operation, improved operational safety, higher productivity, and enhanced efficiency, among others.

A camera assembly for use in medical tracking applications having a range camera and a thermographic camera in a fixed relative position. The range camera is configured to acquire a first image of an object at a first instant of time and a second image at a second instant of time. The thermographic camera is configured to acquire a first thermal image of the object at the first instant and a second thermal image at the second instant. A processor identifies at least one point pair in the first thermal image and the second thermal image. The at least one point pair is mapped to corresponding point pairs associated with the first image and the second image. Movement of the object is determined based on the mapping.

The invention related to a method and a device for displaying an object, in particular biological tissue. Said method having the following steps: a) generating a first image of at least one sub-region of the object using a first device; b) generating a second image of at least one sub-region of the object using a second device; c) ascertaining first coordinates of at least some image points of the second image in a first coordinate system; d) ascertaining second coordinates of the image points of the second image by projecting the first coordinates in a second coordinate system which is different from the first coordinate system and which is assigned to the first device; and e) generating a combined image of the object from the first and the second image using the ascertained second coordinates of the image points of the second image.

Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.
