J. Morita, Irvine, Calif, has introduced the 3D Accuitomo 170, the fourth generation of the Accuitomo product line. According to the company, updates in image acquisition have enhanced the clarity of the images the unit can produce, yet it also offers a reduction in dosage.
The new Dose Reduction Feature decreases patient exposure 30% to 40% compared to the previous Accuitomo model. Now, even the largest field of view of the entire head and neck area can be captured with 25% less dosage than an FMX, F-speed film.* Nine field of view options allow practitioners to keep dosage to a minimum by closely matching the region of interest.
The 3D Accuitomo features a voxel size of 80 micrometers, 14 bit grayscale capability, and resolution greater than two line-pairs per millimeter. It also offers a secure patient stabilization method for both the head and chin to help prevent patient movement during acquisition.
According to the company, Zoom reconstruction is a feature unique to 3D Accuitomo. It always acquires data at 80 micrometers, the highest level of resolution. In order to reduce reconstruction time and file size, the user can choose a lower resolution for display of large fields of view. If a small region of interest is identified in the original scan and more detail is needed in that area, Zoom Reconstruction will produce an 80-micrometer image of that small region without retaking the image.
