Dynamic IGRT: Focusing on precision

Versa-HD is the world’s first linear accelerator to feature integrated dynamic 3D-volume imaging (Image Guided Radiation Therapy – IGRT). This allows imaging of the tumor with CT – like quality to be acquired and reconstructed immediately before a treatment, with the patient already set-up in the treatment position.

Extracranial 4-D Radiosurgery

4-D Extracranial Radiosurgery

  • 1-7 Treatment Sessions
  • Uses powerful motion management technologies- Gating, tracking, freezing or inclusive techniques
  • No knife, painless, bloodless noninvasive procedure, hence no infections
  • Treatment on outpatient basis
  • Treatment time-15 minutes

Indications

  • Medically inoperable Stage 1 lung cancer
  • Primary liver cancer/Mets: inoperable or waiting for transplant
  • Rec. head and neck cancer
  • Pancreatic Ca: inoperable
  • Early Stage Prostate Ca
  • Spine METS- Solitary or multiple

Frameless Intracranial 6D-Stereotactic Radiosurgery

Frameless SRS Advantages

  • Single Treatment Session
  • No knife, painless, bloodless non-invasive procedure, hence no infections, no hemorrhages
  • Treatment on outpatient basis
  • Treatment time- 3mts using FFF technology
  • Max. Lesion size = 3cms

Typical SRS Targets

  • Acoustic Schwannoma: Intracanalicular, Maximum diameter- 3cms and paucity of brainstem compression
  • Non- Acoustic Schwannoma: airing from oculomotor nerve, trigeminal nerve, Abducent nerve and jugular bulb.
  • Pituitary adenoma: Recurrent or residual functioning or non-functioning adenomas located 3mm away from optic-chiasm, maximum diameter – 3cms

Frameless SRS Advantages

  • Single Treatment Session
  • No knife, painless, bloodless non-invasive procedure, hence no infections, no hemorrhages
  • Treatment on outpatient basis
  • Treatment time- 3mts using FFF technology
  • Max. Lesion size = 3cms

Typical SRS Targets

  • Convexity Meningiomas: in elderly trial patient & those near cortical functional brain areas (Language/sensory/motoretc)
  • Skull base meningiomas arising from dura of clivus/petrous, cavernous sinus sphenoid wing & olfactory groove
  • Pineal gland tumors: postop residual or recurrent disease
  • Central neurocytoma: postop residual or recurrent disease

Frameless Intracranial 6-DOF Radiosurgery

Frameless SRS Advantages

  • Single Treatment Session
  • No knife, painless, bloodless non-invasive procedure, hence no infections, no hemorrhages
  • Treatment on outpatient basis
  • Treatment time- 3mts using FFF technology
  • Max. Lesion size = 3cms

Typical SRS Targets

  • Small/large volume deep seated AVM’s with a nidus volume (<10cm3)
  • Small volume cortical AVM’s located at eloquent areas in brain
  • Large volume (>10cm3) lobar location- post embolization residual
  • Angiographic obliteration rate: 65-85% (depends on marginal dose)
  • Disadvantage of RS: 9-18mo delay in complete obliteration

Frameless Functional 6D-Stereotactic Radiosurgery

Frameless SRS Advantages

  • Single Treatment Session
  • No knife, painless, bloodless non-invasive procedure, hence no infections, no hemorrhages
  • Treatment on outpatient basis
  • Treatment time- 3mts using FFF technology

Typical SRS Targets

  • Medically refractory primary neuralgia involving:
    • Trigeminal neuralgia
    • Glossopharyngeal neuralgia
    • Cluster head ache
  • Medically refractory movement disorders: ET/parkinsons disease
  • Medically refractory epilepsy: Medial Temporal lobe sclerosis
