Step 01 of 07

Frame onto the couch

AerFrame base with head rest and vacuum bag onto the imaging couch. 9.1 lb, one lift.

Simulation, done once: the patient registered to the frame, the frame registered to the room, compression set. The coordinates recorded on the worksheet reproduce the setup at every fraction; image guidance confirms the alignment before delivery, as the IFU requires. The daily routine, in section 06 →

Patient to the frame

Registering the patient to the frame.

The patient lies in a solidified vacuum bag inside the frame. With the coordinate arch on the rails, the laser box projects two alignment dots onto the chest. It is positioned so the dots fall on markable skin, and two readings fix that position: Xlaser on the transverse scale, Zarch on the rail through the sight window. That is the registration position, recorded on the worksheet.

First registration

The dots are marked or tattooed. They are the only marks the patient carries.

Every fraction

Arch and laser box return to the registration position. The patient is shifted in the bag and frame until the tattoo marks sit under the dots again.

Xlaser—transverse scale
Zarch—rail, sight window

Example values. Patient and bag are drawn schematically.

Frame to the room

Aligning the frame to the isocenter.

At simulation the couch is shifted to the isocenter and the coordinate arch goes back on the rails. Where the room lasers cross its scales are the isocenter coordinates: Xiso on the transverse scale, Yiso on the side scale, Ziso on the rail through the sight window. They go on the Isocenter Coordinate Worksheet.

At every fraction the frame is moved until the lasers meet those three numbers again. No isocenter tattoo. Image guidance confirms before delivery.

Yiso—side scale
Ziso—rail, sight window

Example values, in millimetres on the frame's own scales. Patient and bag are drawn schematically.

02Why a frame

Completes the stack.
Replaces nothing.

The bag conforms.
CBCT verifies.
SGRT watches.
AerFrame holds.

Conforming, verifying and watching were covered. Holding the patient still was not.

03Two mechanisms, one frame

The frame stabilizes the body.
Compression stabilizes the diaphragm.

The body
The body

Built around the patient.

A U-shaped base gives rigid support around the patient, limiting lateral shift and roll through treatment.

The diaphragm

Compression stabilizes the diaphragm.

Frame-mounted compression applies a controlled, repeatable pressure to limit respiratory motion.

05Online adaptive

Adaptive planning can't account for immobilization attenuation. AerFrame doesn't need it to.

Everything in the beam absorbs dose.

Bags, baseplates, headrests, couch overlays.

The adapted plan never sees it.

Adaptive replans on the patient's anatomy alone.

So the device has to be negligible.

Above 3%, hardware is supposed to be modeled.

Measured — 11 patients, three separately manufactured units

Single-beam attenuation

Axial CT in lung window: the anatomy is bright, the frame around it barely registers

Lung windows in CT.

One exception. Beams through a side rail exceed 3% at 6 and 10 MV. Avoid rail angles in IMRT planning where geometry allows; VMAT generally does not require this.

For the people who handle it

Lighter, simpler, fewer.

06In the room

Nine pounds.
Two marks.
One frame.

Under ten pounds

9.1 lb base. Easy to lift, place and move on the couchtop.

Two tattoos

The only marks the patient carries. Isocenter lives in the frame's coordinates.

Made for MR environments

Frame and MR Safe arch go in; coordinate arch and laser box come off. MR Conditional per labeling.

Less movement, less to manage

Rigid walls leave less room to drift mid-fraction.

Daily setup · four steps
1

Place

Frame and the patient's own vacuum-bag cradle onto the couch. Patient into the bag.

2

Verify the marks

Coordinate arch and laser box to the registration position. The dots land on the patient's marks; shift the patient in the frame if they don't.

3

Frame to the room

Arch to the isocenter position on the rail. Move the frame until the room lasers meet X, Y and Z on the arch.

4

Remove and verify

Arch off. Image guidance confirms the alignment before every fraction, as the IFU requires.

Frames built modern SBRT.

Extracranial SBRT was born in a body frame at Karolinska in 1994. AerFrame is that lineage, rebuilt for adaptive platforms.
