## Abstract

A method for obtaining an intra-oral X-ray image of a subject on a flexible information carrier plate for computed radiography affixes a memory to a surface of the information carrier plate, wherein the affixed memory stores information about the plate and wherein the affixed memory is in wireless communication with a computer, stores at least a first scan date in the affixed memory, exposes the subject and obtains the intra-oral X-ray image of the subject using steps of: (i) storing identification data about the subject and about the image exposed in the affixed memory; (ii) acquiring image data from a scan of the flexible information carrier plate following exposure to X-rays, acquiring at least the stored identification data from the affixed memory, and associating the acquired image data with the acquired identification data; (iii) erasing image content from the flexible information carrier plate; and (iv) storing the acquired image data in a second, computer-accessible memory according to the acquired identification data.

## Claims

### Claim 1

A method for obtaining an intra-oral X-ray image of a subject on a flexible information carrier plate for computed radiography, comprising:
affixing a memory to a surface of the information carrier plate, wherein the affixed memory stores information about the plate and wherein the affixed memory is in wireless communication with a computer;
storing at least a first scan date in the affixed memory; and
obtaining the intra-oral X-ray image of the subject by:
(a) storing at least a job identifier and a scan status for the plate in the affixed memory;
(b) acquiring image data from a scan of the flexible information carrier plate following exposure to X-rays, acquiring at least the job identifier from the affixed memory, and associating the acquired image data with the acquired job identifier;
(c) incrementing a scan count value and updating the scan status in the affixed memory of the exposed flexible information carrier plate;
(d) erasing image content from the flexible information carrier plate; and
(e) storing the acquired image data in a second, computer-accessible memory according to the acquired job identifier.

### Claim 2

A method for identification, monitoring, and tracking of a flexible information carrier plate used in intra-oral dental computed radiography, comprising the step of receiving and transmitting from an interrogator to an RFID tag attached to the carrier plate, the carrier plate being spaced a distance of at least 6 meters from the interrogator.

### Claim 3

A system for identification, monitoring, and tracking of flexible information carrier plates used in intra-oral dental computed radiography.

### Claim 4 (depends on 3)

The system of claim 3 wherein at least one carrier plate has an RFID tag capable of reception and transmission to a distance D1 of about 6 m from an interrogator.

### Claim 5 (depends on 3)

The system of claim 3 wherein the interrogator is in communication with a computer for accessing data, and transmits information to be recorded in memory on an RFID tag.

### Claim 6 (depends on 5)

The system of claim 5 wherein the information to be recorded includes one or more of the following: patient identifier and job number; date/time stamp; intended resolution and other image-related data; image type and orientation; and practitioner or technician name.

### Claim 7

A method for obtaining an intra-oral X-ray image of a subject on a flexible information carrier plate for computed radiography, wherein a memory is affixed to a surface of the information carrier plate, wherein the affixed memory stores information about the plate, and wherein the affixed memory is in wireless communication with a computer, comprising:
(i) storing identification data about the subject and about the image exposed in the affixed memory;
(ii) acquiring image data from a scan of the flexible information carrier plate following exposure to X-rays, acquiring at least the stored identification data from the affixed memory, and associating the acquired image data with the acquired identification data;
(iii) erasing image content from the flexible information carrier plate; and
(iv) storing the acquired image data in a second, computer-accessible memory according to the acquired identification data.
