Toshiba CT systems, Asteion and Aquilion, that are equipped with a PC based computer, or to those older systems (SGI based) that received an improved table by an upgrade purchase. This device is designed to produce cross-sectional images of a human body by reconstruction of xray transmission data from the same axial plane taken at different angles. These images have been proven to be clinically useful in the diagnosis of spine and head injuries, intracranial tumors, blood clots in the brain, eye trauma, soft tissue lesions in the extremities, gastrointestinal lesions, abdominal and pelvic malignancies, and hepatic metastases. CT is also used to evaluate intestinal obstruction!;, assess intra-abdominal abnormalities and to examine musculoskeletal degeneration. This device employs no intended uses that are not in cleared devices already found in the marketplace.

The systems all have a similar table control board. It has been found that this board may cause the table position to be incorrect if the table cradle is moved manually. This is referred to as "Free" mode in the operation manuals. If this error does occur it is possible that the patient could be scanned at an incorrect position.

Toshiba sent a "URGENT: MEDICAL DEVICE CORRECTION" letter to all affected customers. The letter identified the product, the problem, and the action needed to be taken by the customer. Customers were instructed to please avoid moving the table in the "Free" or manual mode as much as possible. If it is necessary to move the table in this manner please verify the table position prior to initiating the scan sequence. If it is noted that the position is not correct, exit the eXam plan and start a new one beginning with the scanoscopy. Please share this information with all users of the equipment and your clinical or biomedical engineering departments. Please find the attached customer reply form. The purpose of this form is for FDA tracking. Please take a moment to complete the form and fax it to the toll free number on the form.".
