摘要： An X-ray fluoroscopic radiographing apparatus comprises a display unit that processes a received X-ray moving image and instantaneously displays the moving image; a storing unit that stores the received moving image as a non-processed raw image; an instructing unit that instructs the raw image to be referred to from the stored raw images; a second display unit that processes the instructed raw image and displays the processed raw image; a changing unit that changes the image process in the second display unit; a second storing unit that stores image process information obtained by the changing unit in association with the instructed raw image; a second instructing unit that instructs the raw image to be transferred from the stored raw images; and a transferring unit that executes the image process associated by the second storing unit to the instructed raw image and transfers the processed raw image to a destination.

摘要： Provided is a radiation phase difference imaging apparatus in which a separation distance between a phase grating and a radiation detector is optimized. The separation distance between the phase grating and a detection surface of an FPD is determined based on the magnitude of noise corruption in a self-image projected onto the detection surface. The magnitude of the effect of the noise is used as a basis for assessing the separation distance. It is determined whether a distance Zd is appropriate for imaging, based on the magnitude of noise corruption in the self-image in a self-image picture which is obtained when the distance Zd is the distance between the phase grating and the detection surface of the FPD. The separation distance can thus be optimized based on actual conditions of an actual X-ray source that emits a plurality of types of X-rays.

摘要： Systems and methods are disclosed for navigating a surgical device toward a target organ in the body of a patient. An example method includes providing a surgical needle and a guide wire, the surgical needle configured for insertion into a vein or a beating heart. The method also includes holding the guide wire within the surgical needle while the surgical needle is inserted into the vein or the beating heart. The method also includes generating output in two modes, the output based on at least one medical positioning system (MPS) sensor on the guide wire, the output corresponding to a position of the surgical needle and the guide wire for navigating the surgical needle and the guide wire toward a target in the vein or the heart. The methods can be carried out directly by a physician or via a computer processor-based surgical system.

摘要： Robust calcification tracking is provided in fluoroscopic imagery. A patient with an inserted catheter is scanned over time. A processor detects the catheter in the patient from the scanned image data. The processor tracks the movement of the catheter. The processor also detects a structure represented in the data. The structure is detected as a function of movement with a catheter. The processor tracks the movement of the structure using sampling based on a previous location of the structure in the patient. The processor may output an image of the structure.

摘要： Provided is a radiation phase-contrast imaging device capable of assuredly detecting a self-image and precisely imaging the internal structure of an object. According to the configuration of the present invention, the longitudinal direction of a detection surface of a flat panel detector is inclined with respect to the extending direction of an absorber in a phase grating. This causes variations in the position (phase) of a projected stripe pattern of a self-image at different positions on the detection surface. This is therefore expected to produce the same effects as those obtainable when a plurality of self-images are obtained by performing imaging a plurality of times in such a manner that the position of the projected self-images on the detection surface varies. This alone, however, results in a single self-image phase for a specific region of the object. Therefore, according to the present invention, it is configured such that imaging is performed while changing the relative position of the imaging system and the object.

摘要： A computer-assisted imaging and localization system assists the physician in positioning implants and instruments into a patient's body. The system displays overlapping images—one image of the surgical site with the patient's anatomy and another image showing the implant(s) or instrument(s). The overlapping image of the implant/instrument is moved over the static image of the anatomy as the implant/instrument is moved. These moving image of the implant/instrument can be an unaltered image or an image altered to intensify or mitigate the anatomical or non-anatomical aspects of the moving image. Sliding these images over one another helps the surgeon in positioning devices or instruments with a high degree of accuracy and with a limited number of additional x-rays.
