PAM-200 Accurate Gating Trigger for the MRI Environment Precision Engineering The PAM Module is an embedded instrumentation pack which provides an accurate gating trigger for use in an MRI environment. The PAM-200 is a complete solution consisting of ECG Acquisition, an Optical Plethysmograph for pulse acquisition, and a pneumatic respiration pad for respiration acquisition. ECG Patient Acquisition The PAM utilizes a 4 lead configuration in a Right Arm, Left Arm, Right Leg and Left leg setup. The Right Leg is the reference lead with Right Arm, Left Arm and Left Leg as the active leads. The PAM provides for two simultaneous vectors. The first vector is Right Arm and Left Leg. The second vector is Right Leg and Left Leg. The two vectors are orthogonal to each other and will result in one vector less effected by magnetic gradients. Accessories PAM System Module by a flexible plastic tube, there is no electrical connection. The bellows has a stiff backing which aids in the compression action of the chest movement. Positive pressure (exhalation) will result in a positive going signal. The respiratory signal is transmitted in the digital stream to the console computer, but the PAM has provision for an analog signal to drive a LED bar indicator which could be located on the gantry or magnet housing. The PAM utilizes a pneumatic technique which responds to the expansion of the chest during respiration. A foam filled bellows is attached to the patient with a strap, and the air pressure in the bellows changes as the chest moves and compresses the bellows. The internal foam provides the spring action to return the bellows to the pre-compressed state. The bellows is attached to the ©2015 Ivy Biomedical Systems Inc. All Rights Reserved.

The optical emitter and detector are located within the PAM housing and the light energy is coupled to the patient through fiber optic cable. The patient connection is through a finger clip similar to a pulse oximetry sensor. The peripheral pulse signal is transmitted in the digital stream to the console computer, but the PAM has provision for an analog signal to drive a LED bar indicator which could be located on the gantry or magnet housing.
