Abstract

A thermal scanning system and method. The thermal scanning system comprises a handheld thermal scanning device with wheels and three infrared sensors that are spaced to scan skin temperature on opposite sides of patient spinal columns of different sizes. Two out of the three sensors are selected for a particular patient, and the wheels are adjustable to accommodate the two selected sensors. The handheld device further calculates the distance traveled by the wheels by measuring the rotation of the wheels. The device has a trigger that allows a user to annotate the location of various anatomical landmarks, such as particular regions of a patient'"'"'s spinal column. The device is adapted to take discrete temperature readings or rolling temperature readings. The thermal scanning system provides graphical displays and data analysis of the temperature readings from the sensors.

a computer receiving and processing the data signals received from two or more of the sensors; and

a selector defining at least first, second and third operational modes for the thermal scanning system, wherein the computer in the first operational mode uses the data signals received from the first and second sensors to determine the skin temperature on opposite sides of a patient'"'"'s spinal column, wherein the computer in the second operational mode uses the data signals received from the first and third sensors to determine the skin temperature on opposite sides of a patient'"'"'s spinal column, and wherein the computer in the third operational mode uses the data signals received from the second and third sensors to determine the skin temperature on opposite sides of a patient'"'"'s spinal column.

2. The system of claim 1, wherein the first size range relates to an infant, the second size range relates to a child and the third size range relates to an adult.

3. The system of claim 1, wherein the sensors scan at least a first point and a second point, the points being located on opposite sides of a patient'"'"'s spinal column or vertebra selected by the user.

4. The system of claim 1, wherein the sensors scan a plurality of points on opposite sides of the patient'"'"'s spinal column.

5. The system of claim 1, further comprising a display device, the display device displaying a first temperature reading from a point located on a left side of a patient'"'"'s vertebra and a second temperature reading from a point located on a right side of the patient'"'"'s vertebra.

6. The system of claim 1, further comprising a display device, the display device displaying a first comparison value and a second comparison value, the first comparison value comprising a first temperature reading from a point located on a left side of a patient'"'"'s vertebra adjusted by a reference value, the second comparison value comprising a second temperature reading from a point located on a right side of the patient'"'"'s vertebra adjusted by the reference value.

7. The system of claim 1, further comprising a display device, the display device displaying a difference between a first temperature reading from a point located on one side of a patient'"'"'s vertebra and a second temperature reading from a point located on the other side of the patient'"'"'s vertebra.

8. The system of claim 1 wherein the sensors are aligned in a linear fashion, with the first sensor on one end, the third sensor on another end and the second sensor positioned between the first and third sensors, the second sensor closer to the first sensor than to the third sensor.

9. A thermal scanning system adapted to scan skin temperature on opposite sides of a patient'"'"'s spinal column for patients of different sizes, the thermal scanning system comprising:

a handheld body having at least a portion which is adapted to be gripped by a user at least when scanning;

a plurality of temperature sensors oriented in a fixed position relative to said body, including a first sensor, a second sensor and a third sensor, wherein the sensors are mounted on the body and arranged in a linear fashion such that the first and second sensors are spaced to scan skin temperature on opposite sides of a patient'"'"'s spinal column of a first size range, the second and third sensors are spaced to scan skin temperature on opposite sides of a patient'"'"'s spinal column of a second size range, and the first and third sensors are spaced to scan skin temperature on opposite sides of a patient'"'"'s spinal column of a third size range, wherein the size range defined between any two of the three temperature sensors is different from the size range between any other combination of two sensors;
