Ct integrated respiratory monitor

Abstract

An integrated respiratory monitor and imaging device apparatus () is provided. The apparatus is useful for establishing pre-operative and intra-operative breath hold congruency in patients and for other interventional work. The apparatus () includes a respiratory monitor system () and an imaging device (). The respiratory monitor system is adapted to engage a patient and generate a respiratory signal representative of a breath hold level of the patient during a breath hold. The imaging device () is adapted to scan the patient during the breath hold and generate a volumetric image data set of the patient. The respiratory sensor and imaging device are operatively connected to associate the respiratory signal representative of the breath hold level of the patient together with the volumetric image data set of the patient. A data storage device () is provided for storing a set of respiratory signals in association with a corresponding set of volumetric image data sets in the subject apparatus (). A scanner gating function is provided to center the image acquisition time at selected points in the respiratory cycle such as at a minimum to minimize motion artifacts in the resultant image.
