## Abstract

Devices and methods for performing CPR on a patient within an imaging field of an imaging device. The device has a compression belt and a belt tensioning mechanism, both located on or in the device such that the head, neck, thorax and abdomen of the patient may be place within the imaging field with the compression belt installed about the patient and the belt tensioning mechanism will be located outside of the imaging field.

## Claims

### Claim 1

A device for compressing the chest of a patient while imaging the patient in an imaging system, said imaging system defining an imaging area which may encompass a portion of the patient's abdomen, thorax, neck or head, said device comprising:
a platform adapted to be disposed beneath the patient's thorax while the patient is disposed within a gantry of the imaging system;
a belt operably connected to the platform and adapted to extend at least partially around the thorax of the patient,
the belt comprising a load distributing portion adapted extend across the patient's chest, and left and right tensioning portions extending from the load distributing portion, downwardly toward a first set of spindles, said spindles fixed on the platform so as to be disposed laterally and aligned inferiorly/superiorly relative to the patient and further to a second set of spindles disposed medially and anteriorly/posteriorly relative to the patient;
a linear actuator, disposed relative to the load distributing portion of the belt such that it is located along the superior/inferior axis relative to the patient and outside of the imaging area when the patient is disposed on the platform with the belt extending around chest of the patient and the patient is disposed within the gantry of the imaging system, said linear actuator operably connected to the tensioning portions of the belt.

### Claim 2 (depends on 1)

The device of claim 1 wherein the linear actuator comprises a pneumatic actuator with an actuator rod, and the tensioning portions of the belt extend inferiorly/superiorly from the second set of spindles to the actuator rod.

### Claim 3 (depends on 2)

The device of claim 2 wherein the pneumatic actuator with an actuator rod are disposed outside the imaging area of the imaging device when the load distributing portion of the belt is disposed within the imaging area.

### Claim 4 (depends on 2)

The device of claim 2 wherein the pneumatic actuator with an actuator rod are disposed outside the imaging area of the imaging device when the load distributing portion of the belt is disposed about the patient's thorax and the patient's head, neck or abdomen are disposed within the imaging field.

### Claim 5 (depends on 1)

The device of claim 1 wherein the linear actuator comprises a rotary-to-linear converter.

### Claim 6 (depends on 1)

The device of claim 1 wherein the linear actuator is located superiorly relative to the patient.

### Claim 7

A method of performing CPR chest compressions on a patient while imaging a patient with an imaging device having a gantry, said imaging device characterized by an imaging field, said method comprising:
providing a CPR compression device comprising a compression belt with a load distributing portion and a tensioning portion, and a tensioning means for repetitively tightening the belt about the thorax of a patient at a resuscitative rate;
placing a portion of the patient within the imaging field;
installing the load distributing portion of the compression belt over the chest of the patient while locating the tensioning means outside of the imaging field;
operating the chest compression device to provide multiple CPR chest compressions and imaging a portion of the patient while the load distributing portion of the compression belt is disposed over the chest of the patient.

### Claim 8 (depends on 7)

The method of claim 7, further comprising the step of providing multiple CPR chest compressions in multiple periods separated by ventilation pauses, and performing the imaging during said ventilation pauses.

### Claim 9 (depends on 7)

The method of claim 7, further comprising the step of providing multiple CPR chest compressions, each compression defining a compression cycle, and performing the imaging at predetermined points in the compression cycle.
