DATABASE CREATED FROM MAGNETIC-RESONANCE IMAGES OF A SPRAGUE-DAWLEY RAT, RHESUS-MONKEY, AND PYGMY GOAT

To obtain a database of accurate anatomical images onto which dosimetr y data of electromagnetic fields could be mapped, a healthy Sprague-Da wley rat, rhesus monkey, and pigmy goat were scanned using magnetic re sonance imaging (MRI). Axial sections throughout the length of the ani mals were collected. Sections were 3 mm thick for the rat and 5 mm thi ck for the monkey and goat. Sagittal sections (2 mm thick) of the rat head were also scanned. Images were recorded on magnetic tape and tran sferred to computer disk for image enhancement and network distributio n. Images are available in 16 bit Big Endian signed or 8 bit TIFF form ats. This is the first database of contiguous MRI axial scans of rat, monkey, and goat available for distribution via magnetic tape (4 mm DD S) or Internet file transfer protocol. Digital transfer of the data wa s selected to preserve the integrity of each image, circumventing the need for the user to scan the images back into a digital format for us e with their software. These images should be useful to physiologists, neuroscientists, veterinarians, anatomists, and teachers. Reconstruct ing these 2-dimensional images into 3-dimensional structures is an eff ective media for conveying spatial anatomical information in a quick a nd comprehensive manner.
