This special marker is designed to imprint important information on the Cine film during diagnostic procedures. You can specify custom information that we will permanently embed into the paddle with lead letters, such as hospital name, address, department name, etc. These letters are colored white for good contrast and easy readability. Changeable data such as patient name, number, or procedure date can be added by sliding mounted lead letters into precision channels. A complete set of 1/4" lead letters, mounted on 1/2" plastic, are furnished with paddle. The set includes four each, A through Z and 0 through 9.
