The CTS Contour Series Bellyboard is the ultimate prone positioning device for patients undergoing colorectal and other pelvic treatments where small bowel displacement is prescribed. Manufactured from the finest carbon fiber, the pelvic prone board avoids the reproducibility challenges of other common foam belly boards that may compress differently under the patient's weight from day-to-day. Side rulers provide additional setup reproducibility, enabling the clinician to easily and quickly align patient and board, reducing the need for large shifts and additional scans after the initial setup CBCT.
