## Abstract

A positron emission tomography (PET) scanner in which a horizontal detector ring is arranged to be moved vertically up and down by a lifting mechanism, thereby eliminating the need for a patient to be in a supine position when performing PET or other types of image scanning.

## Claims

### Claim 1

A method for vertically imaging a region of interest of a patient while the patient is sitting or standing within a PET scanning area, the method comprising the steps of:
providing a horizontal PET scan detector ring having a horizontal aperture, the detector ring having a detector depth of at least six inches and a diameter of at least sixty inches for fully imaging a cross section of significant organ areas of said patient;
attaching at least three vertical ring columns equally spaced apart from each other at an outer surface of said scan detector ring for providing support and to stabilized image acquisition over the minutes required for scan detector ring;
providing transport means to transport said patient to said PET scanning area, the transport means having a seat portion, a handlebar portion, an arm portion, and a leg portion where the handlebar portion and the arm portion are pivotable downward to allow the patient sitting in the seat portion to be scanned while in the transport means;
attaching at least three synchronized motorized devices each respectively to said at least three vertical ring columns for vertically raising said scan detector ring to allow said transport means to enter said PET scanning area in a vertical position and lowering said horizontal aperture of said scan detector ring to scan said region of interest of said patient while said patient is sitting or standing in said transport means and providing vertical precise repeatability imaging so that multiple cross sections are aligned within a software; and
controlling said horizontal aperture of said scan detector ring to scan said patient vertical cross sections which are horizontally flat with repeatable horizontal image planes so that multiple cross sections are aligned while said patient is sitting or standing within said scanning area of said detector ring.

### Claim 2 (depends on 1)

The method in accordance with claim 1 wherein said at least three synchronized motorized devices are electrical motors.

### Claim 3 (depends on 1)

The method in accordance with claim 1 wherein said at least three synchronized motorized devices are hydraulic.

### Claim 4 (depends on 1)

The method in accordance with claim 1 wherein said seat portion is made out of scannable material.

### Claim 5 (depends on 1)

The method in accordance with claim 1 wherein said controlling said horizontal aperture of said scan detector ring includes a computer system.

### Claim 6

A PET imaging scanner for vertically imaging a region of interest of a patient within a scanning area, the PET imaging scanner comprising:
a horizontal scan detector ring having a horizontal aperture, the detector ring having a detector depth of at least six inches and a diameter of at least sixty inches for fully imaging a cross section of significant organ areas of said patient;
at least three vertical ring columns equally spaced apart from each other and attached to an outer surface of said scan detector ring for providing support and to stabilized image acquisition over the minutes required for said PET imaging scanner;
at least three synchronized motorized devices each respectively attached to said at least three vertical ring columns for providing vertical precise repeatability imaging so that multiple cross sections are aligned within a software; and
a computer system for controlling a vertical scanning of said organ areas of said patient within said horizontal aperture of said scan detector ring while said patient is sitting or standing within said horizontal aperture.

### Claim 7 (depends on 6)

The PET imaging scanner in accordance with claim 6 wherein said at least three synchronized motorized devices includes electrical motors.

### Claim 8 (depends on 6)

The PET imaging scanner in accordance with claim 6 wherein said at least three synchronized motorized devices includes hydraulic.

### Claim 9

A PET imaging scanner for vertically imaging a region of interest of a patient within a scanning area, the PET imaging scanner comprising:
a horizontal scan detector ring having a horizontal aperture, the detector ring having a detector depth of at least six inches and a diameter of at least sixty inches for fully imaging a cross section of significant organ areas of said patient;
four vertical ring columns equally spaced apart from each other and attached to an outer surface of said scan detector ring for providing support and to stabilized image acquisition over the minutes required for said PET imaging scanner;
four synchronized motorized devices each respectively attached to said four vertical ring columns for providing vertical precise repeatability imaging so that multiple cross sections are aligned within a software; and
a computer system for controlling a vertical scanning of said organ areas of said patient within said horizontal aperture of said scan detector ring while said patient is sitting or standing within said horizontal aperture.

### Claim 10 (depends on 9)

The PET imaging scanner in accordance with claim 9 wherein said four synchronized motorized devices includes electrical motors.

### Claim 11 (depends on 9)

The PET imaging scanner in accordance with claim 9 wherein said four synchronized motorized devices includes hydraulic.
