摘要： A medical examination apparatus including an imaging means (2,3), a viewing system (4), wherein image data processing means (5) is arranged to facilitate production of different images of a feature of interest such that the pose of the feature is comparable in the different images. The image data processing means (5) estimates the pose of the anatomical feature in a first image generated by the imaging means, produces imaging means control data indicative of the desired imaging geometry for controlling one or more parameters of the imaging means (2,3) for producing a further image having the feature of interest in the estimated pose, and outputs the produced imaging means control data. The output control data may be output in a viewable form and/or output directly to the imaging means (2,3) so as automatically to control the parameters thereof. The output control data can also control the imaging means so as to produce an image having desired intensity characteristics.

The lamp and mirror are configured so that, when the lamp is on, the light therefrom is reflected by the mirror so that the reflected ray field coincides with the hypothetical X-ray field. At least one filter for filtering the X-rays is disposed in the diaphragm housing. To form a relatively small, simple and inexpensive unit for the mirror and the filter or filters that the mirror and the filter or filters are attached to a single disk that rotates around an axis such that either the mirror or a filter is within the hypothetical X-ray field.

摘要： A medical imaging system comprises a C-arm unit having an x-ray source for generating x-rays and a receptor for obtaining image exposures from received x-rays. The C-arm unit moves the x-ray source and receptor along an image acquisition path between at least first and second exposure positions. The C-arm unit rotates about a central axis. Source and receptor brackets mount the x-ray source and receptor, respectively, to the C-arm unit. The source and receptor brackets move at least one of the x-ray source and receptor in a radial direction toward and away from the central axis of the C-arm unit to maintain a desired distance between the patient and the x-ray source and receptor. An image processor collects a series of image exposures from the receptor and constructs a three dimensional volumetric data set which is displayed on a display.
