Reducing Radiation Dose on CT: How IMR Technology Ensures Safety
Learn how modern IMR (Iterative Model Reconstruction) technology on Philips CT scanners reduces radiation dose by up to 80% while providing crystal clear images.

Ultrasound (sonography) has become a medical standard for monitoring health. However, patients often ask: "Is it safe to have frequent ultrasounds?", "Does it harm tissues?", or "Are there long-term effects?". The specialists at Brigid Medical Center help debunk common myths with scientifically proven facts.
Myth 1: Ultrasound is "radiation" that accumulates in the body.
FACT: Ultrasound is NOT radiation. Unlike X-rays or CT scans, which use ionizing radiation, ultrasound uses high-frequency sound waves inaudible to humans. These waves reflect off tissues like an echo, similar to how dolphins navigate. There is zero radiation exposure.
Myth 2: Frequent scans can "overheat" and damage fetal tissues.
FACT: The thermal effect is minimal and strictly regulated. Modern machines display safety indices: Thermal Index (TI) and Mechanical Index (MI). Doctors follow the ALARA principle (As Low As Reasonably Achievable), ensuring the minimum power necessary for a clear diagnosis.
Scientific Evidence
Over the past 40 years, hundreds of large-scale studies involving hundreds of thousands of women have found no association between standard obstetric ultrasound and developmental abnormalities, childhood cancers, or neurological disorders.
Myth 3: It is dangerous to scan the same organ multiple times a year.
FACT: Frequency is determined by medical necessity. For chronic conditions like kidney stones or thyroid nodules, monitoring every 3–6 months is a safe and vital practice to track disease dynamics and prevent complications.
When to be Cautious?
- Doppler Mode: Uses slightly higher power; in the first trimester, it is used only for strict medical indications.
- Non-Medical 3D/4D: Long "souvenir" sessions without clinical purpose are discouraged by professional associations.
