The present disclosure is related to a system. The system may include a gantry, a detector assembly including a plurality of detector modules arranged on the gantry, and/or a cooling assembly configured to cool the detector assemble. Each of the plurality of detector modules may include a crystal array configured to detect radiation rays, and a shielding component configured to shield the crystal array from an electromagnetic interference. The cooling assembly may include a plurality of cooling components. Each of the plurality of cooling components may be embedded in a corresponding detector module of the plurality of detector modules.

A system or method for improving quality in projection and tomographic x-ray, which includes a depth sensing device to measure a depth of at least one body part of a patient from the depth sensing device and a control unit to calculate a thickness and/or circumference of the body part using the depth information. The calculated thickness and circumference information is used to determine an optimal level of x-ray exposure for the body part. The system or method also includes a camera to identify the body part that needs to be examined and to detect any motion of the identified body part.

The present invention relates to navigating in bronchial pathways. In order to provide further improved navigation guidance, a sequence of 2D X-ray images of a region of interest of a bronchial structure with an intrathoracic device (visible in the X-ray images) inserted in a bronchial pathway is provided. The intrathoracic device is tracked in the 2D X- ray images and direction and magnitude of repetitory cardiovascular and respiratory induced motion is assessed based on the tracked intrathoracic device. The assessed motion is modelled and a navigation information indicative of a range of the modelled motion is generated. The navigation information is shown as a confidence reference (310), for example a rEBUS historical trajectory confidence reference, to a user operating the intrathoracic device. As an example, an augmented fluoroscopy 2D image (302) of a thorax region is registered and shown overlaid with segmentation (304) of the bronchial structure and target lesion (312). Further, a confidence reference (314) of the current position of the rEBUS catheter may also be shown.

A nuclear medicine (NM) multi-head imaging system is provided that includes a gantry, plural detector units mounted to the gantry, and at least one processor operably coupled to at least one of the detector units. The detector units are mounted to the gantry. Each detector unit defines a detector unit position and corresponding view oriented toward a center of the bore. Each detector unit is configured to acquire imaging information over a sweep range corresponding to the corresponding view. The at least one processor is configured to, for each detector unit, determine plural angular positions along the sweep range corresponding to boundaries of the object to be imaged, generate a representation of each angular position for each detector unit position, generate a model based on the angular positions using the representation, and determine scan parameters to be used to image the object using the model.

A medical imaging system that includes a gantry having an inner bore surface that defines a bore for receiving a patient, wherein a digital display is attached to the inner bore surface of the bore. The system also includes a patient bed for moving the patient into the bore. Further, visual content is displayed on the display that has a calming effect on the patient.

There is provided a radiographic imaging apparatus capable of facilitating a comparative radiological interpretation of symmetric portions or a temporal comparative radiological interpretation of a same imaging target. The radiographic imaging apparatus includes an image control unit configured to cause a display unit configured to display a plurality of divided screens to display a first radiographic image of a first imaging target on a first divided screen of the plurality of divided screens. The image control unit causes a radiographic image of the first imaging target that is captured at a different time from the first radiographic image or a radiographic image of a second imaging target that is a symmetric imaging target of the first imaging target to be displayed on a second divided screen of the plurality of divided screens as a second radiographic image.

Apparatus and methods are described including an endoluminal device configured to move along a portion of a lumen of a subject's body, an extraluminal imaging device, and at least one computer processor. While the endoluminal device moves along the portion of the lumen, a display displays an extraluminal image of the lumen in which a first indication of a location of the lumen is shown. The extraluminal imaging device acquires a sequence of extraluminal images of the endoluminal device moving along the portion of the lumen. The indication of the location of the lumen that is displayed is updated based upon the acquired sequence of extraluminal images, and the acquired sequence of images is displayed with the updated indication of the location of the lumen overlaid upon the images. Other applications are also described.

The present disclosure provides methods for path planning, and methods, devices, and systems for determining operation guidance information. The methods include obtaining an X-ray image of a target object, and marking a location of a lesion on the X-ray image of the target object; obtaining an ultrasonic image of the target object, and obtaining a fused image by fusing the ultrasonic image of the target object with the marked X-ray image; and obtaining a planned path by performing a path planning based on a location of the lesion in the fused image. According to the methods provided herein, the problem that a single medical image providing relatively little information and without effective reference for surgery can now be solved. The surgical instrument can be implanted based on the planned path, thereby improving the success rate of surgery and reducing surgical complications.

Differences of electromagnetic (EM) properties between healthy and cancerous tissues allow detection of abnormal conditions occurring in a tissue of an animal, for example, intra-operative cancer detection. By using a time-varying EM field, electrical eddy currents are generated in the tissue sample, and assessed using phase-sensitive detection. In some aspects, a change in phase shift between the voltage in a receiver coil and the voltage in a driver coil provide a direct and immediate indication of differences in EM properties of specimens.

An image guidance system for tracking a surgical instrument within the oral cavity. The image guidance system includes a plurality of cameras adapted to be located within the oral cavity to provide intraoral images of optically visible patterns within oral cavity. A processing system receives and processes the intraoral images to recognize patterns and triangulate the locations and orientations of each camera. The processing system uses a reference dataset which defines a reference coordinate system based on alignment to a portion of the oral anatomy. The processing system determines the location and orientation of the tracked instrument based on the reference dataset. In an embodiment, the system includes an oral fixture that is removably attachable to teeth in a patient and is configured to hold one of the cameras.
