    摘要: A system and method for registering pre-operative images of an object with an intra-operative image of the object is disclosed. Prior to an operative procedure, Digitally Reconstructed Radiographs (DRRs) are generated for the pre-operative images of each individual patient. Signatures are extracted from the DRRs. The signatures are stored in a knowledge base. During the operative procedure, a signature is extracted from the intra-operative image. The intra-operative signature is compared to the stored pre-operative signatures. A pre-operative image having a best signature match to the intra-operative signature is retrieved. The retrieved pre-operative image is registered with the intra-operative image.

    摘要: A method for four-dimensional (4D) image verification in respiratory gated radiation therapy, includes: acquiring 4D computed tomography (CT) images, each of the 4D CT images representing a breathing phase of a patient and tagged with a corresponding time point of a first surrogate signal; acquiring fluoroscopic images of the patient under free breathing, each of the fluoroscopic images tagged with a corresponding time point of a second surrogate signal; generating digitally reconstructed radiographs (DRRs) for each breathing phase represented by the 4D CT images; generating a similarity matrix to assess a degree of resemblance in a region of interest between the DRRs and the fluoroscopic images; computing a compounded similarity matrix by averaging values of the similarity matrix across different time points of the breathing phase during a breathing period of the patient; determining an optimal time point synchronization between the DRRs and the fluoroscopic images by using the compounded similarity matrix; and acquiring a third surrogate signal and turning a treatment beam on or off according to the optimal time point synchronization.

    摘要: A system and method for registering pre-operative magnetic resonance (MR) images with intra-operative MR images is disclosed. A pre-operative MR image of an object is received. A set of intra-operative MR images of the object is received. The pre-operative MR image is rigidly registered with the initial intra-operative MR image. The subsequent set of intra-operative images is deformably registered. The pre-operative MR image undergoes both rigid and deformation transformation to match specification of each image with in intra-operative MR image set.

    摘要: An ultrasound scanning system having an ultrasound transducer (10) which provides ultrasound images (33), a computer to process the ultrasound information and to render the ultrasound image (33) correctly positioned and scaled for display on a flat panel monitor (29) which has a display size similar to the actual physical size of the ultrasound image (33). A half silvered mirror (30) redirects the image (33) so that the user (32) perceives the image (33) as if it occupied the actual physical location of the structures (34, 35) appearing in the image (33). An illumination (22) unit projects onto a patient (13) a line of light (3) that is within the imaging plane (4) projected by the ultrasound transducer (10) into the patient (13). Alternatively a video camera may be used to display a guide line (15) that is coplanar with the imaging plane (4). A mechanical mount (16) combines the transducer (10), monitor (29), mirror (30), and source of illumination (22) or video camera in a correct geometrical alignment.
