Abches series

Abches ET

A devise indispensable to enhance accuracy of radiological diagnoses and therapies in the patient’s body area

In the rapidly growing field of radiotherapy, the stability and reproducibility of the patient respiration level are critical issues.
Abches is a respiratory monitoring device based on the unique concept of patient’s self-control of respiration that can be readily integrated in the medical practice in the thoracic and abdominal area.

  • Wireless:  Integrating Bluetooth
  • Gating: Supporting respiratory gated radiation and four-dimensional computed tomography (4D-CT)

Features of Abches ET

Downsized main unit significantly contributes to the flexibility of the mounting position of the unit on the treatment table, reducing interference with the gantry.
The respiratory level is displayed in the compact liquid crystal display (LED). Place the LCD in the position where the patient can directly check his/her respiration level without using the patient mirror.
The unit is completely wireless. The respiratory wave signals detected by the sensor are transmitted wirelessly to the controller.
Battery operated; no cable required.

AbchesET Network Configuration

AbchesET Network Configuration
  • The Abches control terminal operates on a client-server basis, and can register patients' demographic data, record and manage their respiratory data.
  • Integrated with HIS/RIS, the Abches terminal can acquire patient demographic data and output results.
  • The Abches terminal transfers the respiration data to CT for 4D-CT reconstruction.

Respiratory gated radiation and 4D-CT

The unique respiratory phase calculation algorithm enables two types of respiration gated radiation each based on the respiratory phase or on the gating window. The optimal selection depending on the patient respiratory status provides high precision in respiratory- gated radiation.

Respiratory phase is calculated from the acquired respiratory waveform and the respiratory data for 4D-CT can be transferred to the CT gantry.


LCD monitors for the patient

The patient can check the respiratory level marker and actual respiration level on the LCD.

The LCD can be installed separately from the main unit so that the patient can see the marker clearly and directly.
