Image data can be obtained with an imaging device. A location of the imaging device relative to a subject can be determined. A location of an instrument can be tracked relative to the subject using two or more tracking systems operating with different tracking modalities. Also, the tracked location of the instrument can be illustrated relative to the image data.

A first imaging unit obtains a first radiation image, which is imaged under first imaging conditions. A second imaging unit obtains a plurality of projection images by tomosynthesis imaging under second imaging conditions. A reconstructing unit reconstructs a plurality of projection images to generate a plurality of tomographic images of cross sectional planes of a subject. An image synthesizing unit generates a second radiation image employing the plurality of tomographic images. A subtraction processing unit administers a subtraction process on the first and second radiation images, to generate a subtraction image.

A device for fixing the outer boundaries of a region of body tissue in a secondary plane (and optionally in a tertiary plane) during medical imaging, examination, and/or intervention. The caliper device includes a caliper bar with two sliding caliper arms that provide fixation of the region of tissue in the secondary plane. One embodiment provides tertiary fixation with a center plate fixator that extends from a center plate positioner. The caliper device is positioned around the region of body tissue within the primary plane fixation instrumentation. The caliper arms (and optionally, the center plate fixator) move together to “thicken” the region of tissue between them. The device is preferably constructed of radiotransparent material and for single-use applications.

A tomography apparatus for readily imaging an object while reducing radiation exposure doses includes a filter that adjusts distribution of a radiation dose transmitted therethrough from a radiation source, a radiation detection unit that detects a radiation dose transmitted through the filter and through an object, a holder that holds the object, an acquisition unit that acquires information about the holder, and a control unit that controls the distribution of the transmitted radiation does according to the information about the holder acquired by the acquisition unit.

An X-ray table and an X-ray system including the X-ray table are provided. The X-ray table can reversibly rotate without interfering with an X-ray imaging unit while a top surface thereof faces the X-ray imaging unit.

During orthopedic surgeries, body parts are moved in different ways to cause different anatomic features (e.g. muscles or the trochanters) to tighten or loosen, or become more or less prominent during the intended surgical incisions, which can result in easier surgical procedures. Body parts can be moved using a variety of different structures. The exemplary structures described herein can allow for: (1) a person's leg and foot to be rotated about the axis of the leg (i.e., femur/tibia axis); (2) a person's leg can be pivoted generally about the hip/femoral head/acetabulum to vary the angle between the axis of the leg and a median sagittal plane; (3) a person's leg can be moved in a direction parallel to the leg axis; and/or a person's leg can be pivoted in a generally vertical plane, about the femoral head/acetabulum while the axis of the leg and the median sagittal plane remaining substantially parallel.

A medical imaging support includes a substantially flat radiotransparent platform, a plurality of radiotransparent flaps, and closure mechanisms. The platform has a longitudinal direction between a top edge and a bottom edge. The plurality of sets of radiotransparent flaps have a first set of the radiotransparent flaps positioned closer to the top edge in the longitudinal direction than the second set of radiotransparent flaps, and at least one set of flaps includes a first flap and a second flap where the first flap is fixed to the platform proximate a first side edge and the second flap is fixed to the platform proximate a second side edge. The closure mechanisms are positioned on the first flap or second flap of each set of radiotransparent flaps, wherein the closure mechanism selectively fixes the first flap to the second flap of each set of radiotransparent flaps.

A modular patient positioning system includes: a first pegboard having a first pegboard hole; a second pegboard rotatably coupled to the first pegboard and having a second pegboard hole, the first pegboard and second pegboard lying along a common plane in a first configuration and the first pegboard and second pegboard lying along different planes in a second configuration. A first body portion and a second body portion of a patient's body may be positioned and supported in different planes by having the first pegboard support the first body portion and the second pegboard support the second body portion; and a leg positioner including a mounting structure for mounting the leg positioner on the second pegboard and positioning a leg in a predetermined position relative to the second pegboard. The mounting structure of the leg positioner allows for adjusting axial rotation, abduction/adduction, elevation/depression, and/or flexion/extension of the leg.

An immobilization apparatus having at least one or more straps that engage a surface; wherein at least one of the straps comprises a force gauge to determine the amount of force applied to a patient immobilized with said straps; wherein the position of the patient is replicable for treatment of radiation and other head or neck treatments.

Disclosed herein is a complex spine-inspection support apparatus capable of multi-posture correction, which can apply various acting forces in a longitudinal direction of a spine while stably maintaining a patient's posture, can transmit a constant bending force to the left and right, thus facilitating accurate and various inspections, and can observe a spinal disc ligament varying depending on a posture. The present invention provides a spine-inspection support apparatus for supporting a patient's posture in equipment including a spine inspection, the apparatus including an apparatus bed configured to allow a patient to lie on an upper surface thereof; a lower-body support unit movably provided on a first end of the apparatus bed in a longitudinal direction of the apparatus bed to come into close contact with a patient's buttocks and configured to allow a leg region to be seated in an “L” shape; a lower-body support unit driving means provided on the first end of the apparatus bed to linearly move the lower-body support unit; a leg holding means provided on the lower-body support unit to hold the patient's leg region; an upper-body support means provided on the apparatus bed to support and hold the patient's upper body; and a control panel for controlling an operation of the lower-body support unit driving means.
