[TETRIS-RT]Automatic compensation filter manufacturing system

Based on the block arrangement defined during therapy planning, a compensation filter is automatically manufactured and installed in the Linac system to facilitate IMRT.

[FM-R1 Advanced]Automatic compensation filter manufacturing system with rod arrangement

The compensation filter is manufactured from rod-formed material and installed in the Linac system to facilitate IMRT that requires a particular dose profile.

Product Features

High-precision IMRT

Complex MLC movement is avoided to provide high-precision IMRT by assuring a beam intensity with the block filter.

Shorter treatment time

Rectangular field radiation eliminates intermittent sequences, resulting in a 60% shorter IMRT treatment time.

Secure and eco friendly

The manufacturing system is equipped with an arrangement check function that avoids arrangement errors. The block materials are reusable, thereby avoiding the production of clinical waste.

Manufacturing compensation filters

Multi-layered bolus

apexadmin — Fri, 27 Dec 2013 03:34:57 +0000

A range-compensation filter constructed from plastic for each proton beam plays a crucial role in forming the treatment volume corresponding to the targeted tumor profile.

Based on the bolus shape defined during therapy planning, 3 mm thick plates of bolus material are punch-pressed at high speed. After inspection of the shape, these plates are placed in a dedicated case and formed into a bolus block.

Product Features

High-precision processing and inspection

The bolus is divided into 3 mm thick plates and processed by a high-precision turret punch press machine. The bolus is then optically inspected to achieve an overall processing accuracy of < 1 mm.

High-speed processing and inspection

Processing the maximum target volume bolus (200 · 150 · 195 mm) takes no longer than 1 hour and less than 30 minutes for a standard size bolus.

No need to deburr

The punching process suppresses burr formation and requires no deburring after processing. The block manufacturing method also automates the flow of processing and inspection and simplifies the entire manufacturing process.

Turret punch press

The bolus material plate is punch pressed with a regular die. The punch-pressed plates are multi-layered and placed onto the bolus case.

abches

apexadmin — Thu, 26 Dec 2013 08:22:42 +0000

abches is a device that allows the patient to self-control the respiratory motion of the chest and abdomen.

The control of respiratory motion is crucial for enhancing precision and assuring reproducibility in CT data acquisition and radiotherapy involving respiratory movement of the lungs and other organs.

A high degree of respiratory control requires patient cooperation. Stable respiration is very difficult to achieve in situations in which patients cannot monitor their own respiration.

Therefore, a patient-friendly, easy-to-use device has long been sought.
Abches is the ideal solution.

Product Features

Simple structure with no power source or batteries

The principal parts of Abches are constructed of resin. No metal is used.

The main body of the device, consisting of the measurement unit and stand, weighs only 1.5 kg.
No electrical parts are used; therefore, no electricity or battery is required.

Simple and accurate respiratory control

Abches enables visual confirmation of respiration level on the basis of the following principles:

1.Simple, easily viewed display of respiratory level

The arms with chest and abdominal contacts move together with respiratory motion.

2.Clear indication of respiratory level

The motion amplitude of the two contact points on the body is displayed as rotational movement of the needle of the indicator unit.

3. Visual confirmation of respiratory level

The patient controls their respiratory level by confirming it on the indicator. (Visibility is enhanced with the dedicated mirror on.) The transparent indicator allows the operator to confirm the level from the other side of the patient.

Applicable to a wide range of modalities

Abches is compatible not only with Linac and X-ray CT, but also with PET, and can be used inside the gantry.

Abches is effective at reducing image degradation and artifacts caused by body motion.
