Introduction. Spatially registering SPECT with CT makes it possible to anatomically localize SPECT tracers. In this study, an accurate method for the coregistration of ultra-high-resolution SPECT volumes and multiple cone-beam CT volumes is developed and validated, which does not require markers during animal scanning. Methods. Transferable animal beds were developed with an accurate mounting i...

OBJECTIVES To analyze the availability of bone in the interforaminal region and to demonstrate the variation in diagnosis between panoramic x-ray and cone-beam computed tomography (CBCT). MATERIAL AND METHODS In 50 patients and in 5 areas of each, a series of parameters concerning available bone were measured on both the panoramic and the CT images. RESULTS Panoramic images underestimate th...
